The Virginia also has such tubes ahead of the sail.

big meaty 10k ton ssgns are the future of the industry.

the next yasen with 10tubes will be able to carry 10 bulava also i think..a mini ssbn

7th Fleet Tests Innovative Missile Defense System
GUAM (NNS) -- U.S. 7th Fleet and the Navy Warfare Development Command (NWDC) tested how radar-absorbing, carbon-fiber clouds can prevent a missile from detecting and striking its target, June 21-25.

The Navy tested these manmade clouds, called maritime obscurant generator prototypes, to assess their tactical effectiveness for anti-ship missile defense.

The systems and tactics were tested under a variety of at-sea conditions using assets from the U.S. Army, Navy, and Air Force to evaluate how the radar-absorbing, carbon-fiber clouds can protect naval assets as part of a layered defense.

Adm. Robert L. Thomas Jr., commander U.S. 7th Fleet, kicked off the multi-ship experiment in Guam.

"Pandarra Fog is example of the quick-turn integrated technical and tactical development the Fleet is doing to master electromagnetic maneuver warfare and assure access of joint forces," said Thomas.

"Pandarra Fog showed the value of quickly bringing together scientific and joint forces to tackle our hardest warfighting problems," said Antonio Siordia, U.S. 7th Fleet's science advisor. "This isn't just smoke or chaff, this is high tech obscurant which can be effective against an array of missile homing systems."

A shipboard device generated the carbon-fiber particles which were suspended in a cloud of smoke. These clouds can absorb or diffuse radar waves emanating from the seekers of incoming missiles and potentially obscure friendly ships from those missiles.

The experiment demonstrated how maritime obscurant generation can be a key enabler of offensive maneuver of the Fleet despite the global proliferation of anti-ship cruise and ballistic missiles.

"We are developing a layered approach using a full spectrum of active and passive capabilities to give us the advantage," said Capt. David Adams, who leads the 7th Fleet Warfighting Initiatives Group. "It is not just about the technology, but also practicing how the Fleet will employ these emerging capabilities."

"A defense in depth approach has a lot of advantages. Not only do we know the smoke is effective, it adds a level of uncertainty and unpredictability to the equation," said Adams.

In addition to having a significant level of effectiveness, the systems are relatively inexpensive when compared to other countermeasures and can be tactically employed through typical Fleet maneuvers. The materials are environmentally friendly and sized to maximize operational effectiveness.

"Our initial assessment is the testing was very successful in terms of tactical employment, usability and cost-effectiveness." said Adams.

we have often wondered what to do about the necessary nuisance known as the RBU6000 that is present on every IN warship and has the RCS of a village.
the royal navy is going to mount this Centurion universal decoy launcher system on the Type45 and some other ships it seems.
stealth housing, easy loading, mixed payload of anti-torpedo decoys, IR decoys and radar decoys.

we need to develop something similar domestically and finally get done with the rbu.

talk about lobbying power! boeing has put up a Growler microsite and has a ad in washingtonpost.com saying @protect the growler@ http://fa-18.com/

it has videos, maps, details on why the Growler must be protected by the congress with more funds!!

it has easy links to sign petitions and contact congressmen!!

Support EA-18G Growler
We believe that the U.S. Government must responsibly invest taxpayer dollars on EA-18G Growler aircraft to increase electronic attack air support, critical to dominating current and future battlefields. During this time of serious economic challenge, it is critical for Americans to come together to protect this unique capability, our nation’s industrial base, workforce and security.

The Growler and Super Hornet production line is an investment in the United States economy. In total it supports more than 60,000 highly skilled jobs in 44 states, including small businesses. If production ends, so would the ability to sustain these jobs and businesses. The below map shows the Growler and Super Hornet’s impact in every state.

Navy’s $670 Million Fighting Ship Is ‘Not Expected to Be Survivable,’ Pentagon Says

Pretty much nothing works.
Ah, the Little Crappy Ship. It's a white elephant, but a million times better than what they originally tried to build – a glorified FAC-M known as "Streetfighter". The basic idea was to cram 8 AShMs into a 300-ton vessel capable of doing 60 knots. That's the equivalent of building a Sopwith Camel size aircraft capable of carrying a dozen BVR AAMs and flying at Mach 3.

After the whole Streetfighter concept died a natural death, the geniuses who conceptualised it came with with the LCS; a "multirole" replacement for the missile boat, FAC, minesweeper, ASW corvette, amphibious ship, and everything in between. Hell, the bright spark that conceived of the LCS/Streetfighter even imagined putting a squadron of F-35s and a handful of SH-60s on it. Go figure.

The main problem with the LCS stems from its size. A small vessel cannot defend itself effectively (which is in keeping with the design's premise that ships are indefensible against modern missiles anyway, so you would rather have a large number of small ships), it lacks the seakeeping qualities of larger vessels, it carries fewer weapons, the electronics have to be put in sub-optimal locations because of the restricted space, and so on and so forth. All these shortcomings are only amplified by the magic pill that is "modularisation". You can't just modularise mission-specific weapon and sensor fits in a warship. Each mission really requires a platform tailored to it. Air defence requires a powerful radar, a highly capable comms suite/datalink, and a magazine that can carry a significant number of missiles. The first two need to be positioned to mitigate the effects of electronic interference – a tough challenge at the best of times. ASW, on the other hand, requires the ability to carry more than one helicopter, a powerful sonar, and a hull designed to minimise flow noise. The combat management hardware and software of the two bear very few similarities. Both are eminently doable; the problem arises when you try to build one small vessel to support both mission types with 'modules' that can be swapped out quickly. The requirements are so different that you end up making great compromises and build a ship that is neither here nor there.

In the end, the 'modules' turned out to be so expensive that there simply weren't enough to go around. What that means is that each vessel will basically be equipped with one module onlee; and the "swap stuff out and plug new stuff in" dreams aren't going to come to fruition. Ultimately, the US Navy ended up with a glorified frigate that works great in theory but breaks down at the drop of a hat (where have we heard that story before?)

And then there's the speed. I'm not sure if anyone has really explained for what the USN intends to do with a ship that can travel at 40+ knots. The most sensible answer yet has come from the USS Freedom's first captain. He said he could use the massive wake created by the high speed to topple and sink pirate skiffs. Nobody was sure if he was serious or joking.

When you have a boondoggle on your hands that makes the Zumwalt look good, you know you've got problems.

what is wrong with the zumwalt?

other than cost and the fact I am not sure where they want to use its huge main cannons and 100 mile shells?

it might be better used as a stealthy boost phase ABM/LACM vehicle as it can lurk alone somewhere along expected flight paths and still retain a huge self defence SAM battery if the two guns are deleted. problem is there are not that many enemies who need the massive firepower to engage - only two come to mind India and Cheen.
with nearly 60 DDGs already in service they dont need VLS cells for a long long time.

the gun system might actually be more useful in the LCS or smaller 'modular FACs' :mrgreen: - these can dart close to shore at high speed, unleash 100s of shells in a few mins and dart back to cover again.

Kilos 636.3s are being built in large numbers.6 for Vietnam,6 for Russia and now 2 for Algeria.The IN could easily acquire to make up for the loss of the SRakshak and the dismembered one at HSL.The pic of the SRakshak after salvaged showing the hull still intact after the massive explosions which scuttled it,indicates the intense strength of Russian double hulled subs.No western conventional sub would've remained intact after such a disaster.

Algeria orders two Kilo submarines from Russia

Written by defenceWeb, Friday, 27 June 2014
A Kilo class submarine.Algeria has ordered two Kilo class diesel electric submarines from Admiralty Shipyards in St Petersburg, Russia, with the contract currently underway. They will join the four already in Algeria’s fleet.

The ITAR-TASS news agency yesterday quoted Admiralty Shipyards director-general Alexandre Bouzakov as saying that "The date of the start of construction of two submarines to the foreign customer has been fixed, the contract is underway.”

The two Project 636 Varshavyanka (Kilo class) submarines will be delivered by 2018. The value of the contract may be more than $1.2 billion, according to Interfax.

Algeria already operates four Kilo class submarines. In June 2006 Rosoboronexport signed a contract with the Algerian Navy for the construction of two Project 636 Improved Kilo class submarines under a roughly US$400-600 million contract. Construction of the first submarine started in 2006 and the second began in 2007. They were handed over to the Algerian Navy in March and September 2010 where they joined two Project 877EKM Kilo diesel electric submarines, which Algeria received in 1987-1988. The latter two were upgraded by Russian shipyards.

The Project 636 Varshavyanka class is mainly intended for anti-shipping and anti-submarine operations in relatively shallow waters. The tear-drop hulled submarine is 72.6m long, 9.9m wide and can dive to 300 meters. The design has a displacement of 3 076 tons. Underwater, it reportedly has a speed of up to 25 knots. The complement is 52 and the submarine has an endurance of 45 days. The boat is fitted with six 533 mm torpedo tubes and carries up to 18 homing or wire-guided torpedoes, or 24 AM-1 mines.

The outer hull is covered with sound damping tiles and its machinery as well as design is regarded as very quiet. Designed by the Rubin Central Maritime Design Bureau of St Petersburg, the submarine entered service in 1982. The type was originally built at the Komsomolsk shipyard and lately by the Admiralty Shipyard in St Petersburg. It is in service with the navies of Russia, China, Vietnam, Iran, India and Poland, among others. Some 50 have been built.

Algeria is in the process of expanding its navy in recent years as it faces problems such as smuggling, illegal migration and indigenous terrorism. In April 2012 it emerged that Algeria had signed a contract with the China Shipbuilding Trading Company for three light frigates, after ordering two Meko A200N frigates from Germany’s ThyssenKrupp Marine Systems in March 2012. The three light frigates will displace around 2 800 tons fully loaded, and will be powered by MTU diesel engines. Algeria has also ordered two new Tiger class corvettes from Russia. The Tiger corvette (Project 20382) is an export model of the Project 20380 Steregushchy class, which is the Russian Navy’s newest corvette class.

In January Italian shipyard Fincantieri launched the Algerian Navy’s Kalaat Beni-Abbes landing helicopter dock ship, which will be delivered to Algeria later this year. Algeria may order a second of the type.

So many things.

The hull, because of its 'tumblehome' shape, causes the vessel to suffer serious stability issues, especially in bad sea states. The wave-piercing bow just makes matters worse. Instead of 'parting' a wave as good hulls do, the Zumwalt goes straight through. What that means is that the wave washes over the deck and slams into the gun mount and bridge like a ton of bricks. Ships tend to dislike salt water crashing into structures and moving surfaces. That leads us to another problem. With all the water flowing over the deck, you can't service and repair things unless the ship is stationary, because crew members would get swept off.

The sensors are another problem. Here's a picture of the Arleigh Burke class Destroyer, and here's one of the Kongo. Notice how the sensors and comms are all nice and spread out? On the Zumwalt, they crammed everything into one small superstructure. There were reports that the electronic interference was just nasty. The SPY-3 was apparently jamming the comms antennae and gun controls, among other things.

And there's the automation as well. Automation is nice and dandy when sailing in peacetime. It's even helpful when it comes to reducing manpower requirements in engine rooms and the like. But it's a problem when it comes to servicing and damage control. All the automation (food, ammunition, HVAC, engines) means there are more moving parts that require servicing and repair. But with your reduced manpower, you can service fewer things at a time; simple math. You can get past a few of these things with better, more reliable equipment, but only up to a limit. It only gets worse when there's an enemy shooting at you and causing large-scale damage to your vessel. Between putting put fires, plugging holes, and getting machinery back up again, and fighting the enemy, how much do you expect a reduced crew to do? Oh wait, there's an automated firefighting system. This is what Wiki has to say about it: "Water spray or mist systems are proposed for deployment in the Zumwalt-class destroyer but the electronic spaces remains problematic to the designers. Halon/Nitrogen dump systems are preferred but do not work when the space has been compromised by a hull breach. The GAO has noted this system as a potential problem yet to be addressed."

But it has got some stealth going for it, which is nice...

er, but the zumwalt hull problems would already be well known in modelling and lab tests, yet they are building 3 of these massively expensive ships.
surely it cannot be as bad as you say...

at least it would prove a few ideas like the PVLS, the AGS, the integrated back end for multiple front end radars, electric drive propulsion, lots of conformal antennas is confined spaces, effects of splashing heavy seas on low slung stealth hulls, operating rotary drones, automation......if they revert back to a more conventional DDG51 type design for the future I figure all these techs will be well proven and cost effective with less errors....simply take a normal type hull and stick the kernel of the zumwalt inside it.

I am getting a strong feeling the future of american escort AAW / ASW ships is going to be unmanned LCS sized vessels of high stealth, next gen SAMs and radar ... all controlled remotely in a hive-mind network from the manned carrier or Command ship in the battegroup. these can provide close escort or rove around providing SAM coverage and launching HWT/UUV/drones for ASW ..... AAW & CIWS is a pretty standard problem - beat back dozens of a/c and missiles using available networked resources in the fleet...amenable to unmanned launch platforms and automation imo. CIWS is already fully automated once the operator lets it into auto mode.
ASW is probably a bit trickier as contacts can be lost and regained due to water conditions and +ve id of intent is tougher.

well, much of the criticism was around 2006-7. Since then they built a 1/4 size model and tested it. Being the first ship of its kind I am sure there will be some challenges (the Russians and French gave up on this design decades ago). Cost was the factor that reduced the number of Zumwalts from 32 to 3 (so claim various articles).

However:

From Paint To Littoral Combat Ships, Navy Scrambles To Save Dough
................................ More recently, there have been attempts to build stealthy vessels with radar-eluding hulls; but the only example to enter production, the DDG-1000 destroyer, proved so expensive the Navy cut the planned 32 ships to three.

In place of the cancelled stealth ships, the Navy restarted the production line for the VLS-equipped DDG-51 Arleigh Burkes. Like their predecessors, the CG-47 Ticonderoga cruisers, the DDG-51s are built around the Aegis system to defeat incoming air and missile attack. What determines their combat capability is not so much the hull, engine, and guns but the kinds of missiles loaded in the VLS tubes and the radar, computers, and software that direct them.
But, no one seems to claim that it is a bad design.

That is the essence of the ship. If it works as planned it will be the base for future ships. As mentioned there has been quite a bit of risk reduction of the basic design and the fact that they have proceeded seems to give a sense of relative confidence in the basic overall design. Of course this will be verified shortly as the link above mentions. They are surely not writing off the design and its expected performance based on what others may think about it. Unless one has hard testing data from the studies that have happened till date based on which they marched on one cannot claim anything with any degree of certainty. There is a reason they go out and take the ship for testing in heavy weather.

The Electromagnetic rail gun is going to begin sea testing in less then 2 years. Following that they will take what they have learnt out at sea and incorporate changes to the design. Following that will be integration and testing of a representative system. The Zumwalt will be the ship that takes this out given its surplus power. Goal is to achieve 110 nm with the first gen Railgun with the ultimate ambitions to achieve close to 200nm with future guns. This year the HASC has recommended that the Railgun program be transferred (management) over to the MDA. This will most likely result in better funding compared to the ONR budget and faster mission testing given the relaxed constraints of that agency. The EM Railgun is the future of the USN's offensive capability and missile defense and any future ship will have to be capable of handling such a weapon. The Zumwalt will prove these systems and the basic design so that it can be used as a base for ships of the future.

The Integrated power system is going to be the base without which no future technology can be incorporated into the ships of the future. The automated systems are radical, and like all radical concepts they will have to be sorted out. If challenges were a detriment nothing radical will ever come about and prove itself. Everything will be tested as per the survivability and mission effectiveness requirements set forth in the program. The radar and interference is a very minor issue. Electronics interference happens and is sorted out. Thats the entire point of testing the avionics and sensors before declaring operational capability. Stealth brings compromises and challenges. If you want stealth without any sort of compromise then its best to not design it in the first place. The GAO reports on these and these reports are transitional and do not reflect the permanent state of affairs

laser gun for ciws is also probable fleetwide. again very high surge power needed repeatedly I suppose. next gen electrical system needed to run a couple of these on each beam to zap inbounds. smaller EM railguns firing ciws rounds could impart much higher muzzle velocity to inert rounds and hence achieve greater engagement ranges than the phalanx...perhaps even out to ESSM range in LOS mode.

The Navy cancelled it a few years ago, before changing their minds and deciding to buy three. They knew of the problems, but you underestimate the zeal of those pushing "new and improved", "disruptive" ideas and show down those "hide bound curmudgeons" just for the heck of it. :lol: Yeah, it's bad. They knew about the hull problems. But they decided that this silver bullet named 'stealth' made everything worth it.

I get your points about newer techs making it to operational vessels and improving their performance. But the right place to develop and test so many path-breaking items is a laboratory, not an operational vessel supposed to replace most of your destroyer fleet.

Some home truths.Greater automation means less crew to handle emergencies,esp. when a warship suffers battle damage.Today's stealth designs also have a fatal flaw.There is no continuous open deck which runs all round the ship to allow the crew to access any part of it for maintenance/repair.The hull and superstructure meet flush with openings hidden with stealth panels for the launch/cutter,TTs,etc.Compare the Delhi with the Shivalik.The more complex a warship gets with increased automation,and packing together a whole suite of electronics into a small superstructure brings with it the deserved problems of mutual interference,etc.Such tightly packed warships can be put out of action by a single bomb or missile.The last big war was the Falklands,which reiterated the WW2 experience that warships get hit,suffer extensive damage and must be able to survive even a missile attack.Many of today's warship designs would be disabled as said before with just one hit. The larger the ship and hull,with more duplicated eqpt.,the greater its survivability.The USN's LCS ships ironically cannot operate in the littorals independently and survive.The multi-role corvette is increasingly becoming the warship of choice for medium and smaller navies,affordable and easier to operate.

When it comes to subs however,greater reliable automation definitely helps.A sub could be smaller in size.It also reduces the space req. for crew support,or extra space for extra eqpt./stores.The Swedes have had some remarkable designs with hugely reduced crew for small conventional subs.Russia too with its latest SSGN has a crew of just 90.

next gen techs are always costly and need lot of maalish-palish to keep going. the days of old rugged kit are gone for sure.

while 1 or 2 existing DDG51 vessels could have been gutted to test the new techs piecemeal, stuff like that huge radar , elec systems and the AGS would need massive changes so probably not worth it to destroy a working ship for that. so choice between building new test ships or DDG1000 why not just build a few and get some real world exp on the hull as well. helps the local shipbuilding industry like bath iron works, maine.

To the best of my knowledge the Zumwalt was never cancelled and brought back for just 3 ships, the program transitioned from a more ambitious one to where it currently stands but that is hardly a cancelation or something that is not routine. The CGX was cancelled and that still remains cancelled. It is however still the preferred design for that class and will most likely find its way into future ships in the post 2030 period. That is of course if the Zumwalt experience validates the design, architecture and electronics sub systems. The design and its stability has been tested and the entire report has never been made public and the GAO conclusions are contested, and will be proven once and for all when the heavy weather testing concludes (it begins soon). Testbeds were developed to test the design, the electric architecture and other technology inserts.

Cost is the main concern, and would have been even if the proposed 30 odd ships were procured. Cost will always be a concern if anything is tried in the USN that is not just incremental to what they are developing. The main payoff comes if the technology, design and the concepts are validated. This will pay off in the future when the basic design is used for other ships that will be procured in much larger volumes and replace the Burke.
These concerns have existed for a decade, but the US Navy continues to express confidence in the stealth-enhancing design based on their modeling and testing to date. A 1/20 scale, 30-foot scale model has been taken it up through Sea States 8-9 [hurricane-force seas and winds], based on the standard US Navy requirement for stability in ships is a 100-knot wind and using a model of 1969′s Category 5 Hurricane Camille. A 150-foot, 1/4 scale steel hull has also been built and tested for stability, and the arm’s-length US Naval Technical Authority has determined the Zumwalt’s design to be safe.

Stealth is also going to be an increasing emphasis on modern ship building. With stealth come compromises that need to be worked around. This has happened in the aerospace industry and will continue to happen in ship building.
Automation in both manning and gun loading is here to stay. It may turn out that the automation was a over estimated and that the crew requirements need to be upped. This can be done and the program has room for that. As things stand, the 3 ships and the basic designs would be the core of where the USN want from an capability addition point of view. Lasers for close defense, and the EMRG will all be tested on the various test beds and the only logical insertion ship for these is the Zumwalt. Prove these and the capability is greatly enhanced both from an offensive and a defensive stand point. As I pointed out there is a strong wave for a shift of the EMRG to the MDA, this will ensure a rapid rise in funding compared to the more steady stream that comes from the ONR. This will also most likely fund 2 programs simultaneously. The 2016 at sea testing would be pivotal and how rapidly they can produce relevant guns post that will determine the maturity of the insertion but given the priority this has been given even in a cash strapped budget, i see it sooner rather then later.

USS John Paul Jones Makes History with Live Fire Missile Tests
PACIFIC OCEAN (NNS) -- Guided-missile destroyer USS John Paul Jones (DDG 53) successfully conducted a series of five live-fire tests for the Baseline 9C Aegis Combat System during Combat Systems Ship's Qualification Trials (CSSQT) and Naval Integrated Fire Control Counter Air (NIFC-CA) capability, June 18-20.

Over the course of three days, the crew of John Paul Jones successfully engaged six targets off the coast of Southern California, firing a total of five missiles that included four Standard Missile-6 (SM-6) missiles and one Standard Missile-2 (SM-2) missile.

One of these exercises, designated as NIFC-CA AS-02A, resulted in the longest surface-to-air engagement in naval history.

During the underway period, John Paul Jones also conducted its first ballistic missile tracking exercise while simultaneously tracking two supersonic and two subsonic missile targets. This event fully demonstrated the capabilities of Aegis Baseline 9C and of John Paul Jones as the first Integrated Air and Missile Defense (IAMD) destroyer.

"It's a great step forward for the surface navy and our integrated war fighting capability," said Fire Controlman 1st Class (SW) Matthew Miller. "I'm proud, really proud, to be a fire controlman, and proud to be in the Navy."

These CSSQT successes are attributed to the hard work and dedication of each and every member of the John Paul Jones crew. The long road to these missile firings started in the BAE ship repair facility in San Diego during 2012 when the ship started combat systems modernization as part of the destroyer modernization program.

Over the course of a year, John Paul Jones received the latest commercial off-the-shelf computing infrastructure, SPY-1D transmitter upgrades, and a multi-mission signal processor which comprises the Aegis Baseline 9C suite.

Since then, the crew has worked diligently to ensure that the systems are not only operational, but that they will operate effectively for future ships.

"It is my honor to serve on such a fine warship and be able to sail with the men and women who tested and demonstrated this amazing capability," said Cmdr. Andrew Thomson, the ship's commanding officer. "From the concept development phase, through design, build, installation, and test many hard working Americans came together to field this capability. I consider myself lucky to be part of that amazing team."

Thomson said that with these tests, the crew of John Paul Jones has proven that they are ready to assume the role as the Navy's Integrated Air and Missile Defense test ship following a change of homeport to Pearl Harbor later this summer.

According to Thomson, CSSQT is just the beginning. In the coming years, John Paul Jones is expected to test newer and more advanced systems that will be used to defend the nation and U.S. and allied forces overseas.

Depends upon what you want to defend. While the initial shells they are going to be testing in 2016 are going to be command guided, GPS guided shells aren't going to be far behind. Current cost per round is $25,000 and the speeds are between mach 5 and mach 7 with a end target goal of 200nm @ mach 7.5. I am not aware of a solution to counter such ammo in any stage of its trajectory in a manner that is not cost prohibitive. But i could be wrong. The main advantage is of course for AsW and for BMD and Anti ship weapon defense and that seems to be the increasing focus as many voices call for the management of the entire program be shifted to the Missile Defense agency (from the office of naval research).

Missile Defense Agency Nudged to Pursue Navy's Rail Gun
A draft House bill envisions the Missile Defense Agency assuming management from the Navy of a project to develop an electromagnetic rail gun.

The House Armed Services Subcommittee on Strategic Forces in its mark-up of yearly defense authorization legislation noted the promise of the technology as a "more affordable air and missile defense" alternative, Inside Defense reported on Thursday.

The legislation includes a directive for the Missile Defense Agency to work with the Pentagon's Strategic Capabilities Office to draft a report by mid-November that details a testing strategy for determining the "suitability of this [electromagnetic rail gun] technology for transfer to MDA for further development activity."

The subcommittee said the Missile Defense Agency, with its special authority to speed along the acquisition process, was in a unique position to move forward the work done thus far by the Navy and the Strategic Capabilities Office.

The Missile Defense Agency has already singled out the rail gun as a "priority" technology in light of its possibilities as a comparatively reasonably priced antimissile technology for use against theater-level ballistic missile threats.

The rail gun is operated by an energy pulse instead of explosive fuel and is envisioned for use against a large number of targets, including cruise and ballistic missiles, and warships

on that note the whole idea of short range defence using VL-Mica/Derby(spyder)/Humraam active radar guided AAMs adapted for SAM role sounds very very costly to me. the pro is once out of the tube with their initial waypoint no further guidance needed as they active immediately and the target will be well within the 20km range of their onboard radar. plus enemy ARM/jamming of ground radars will not defuse them.

the con is the massive price tag of around $1 mil per missile.

if a formation of say 4 J17 launches 16 munitions, thats 20 targets...enough to saturate the battery that is within range. a follow on wave of 4 will have a free run until the VL boxes are reloaded. cheap quad packed RCS enhanced unguided drones could be also used to attract the bees and leave the beehive unguarded :cry:

imo a smaller version of Akash, using same comps but smaller more agile airframe desired from AStra, and guided by the very same set of radars and control links will slot nicely in with the current akash batteries and protect both the battery itself and the point targets like airbases and camps. cost will likely be 20% of a hi-end munna like mica-EM or python5.

Singha Ji, The close range Laser is being precisely developed to solve the major problem of a slow loitering UAV or a Stand off munition that can launched at very low cost. The number being thrown around are a 50,000$ weapon requiring a 1-3 million dollar missile to shoot down. The USN has a lead here but I believe we are designing one as well. The capability of such a system will likely evolve incrementally every generation to a point where its scope of usage will extend beyond the current abilities.

New US thinking (back to the future) fro littoral warfare ,use small single tasked warships in the littorals,aka known to have been Adm.Gorshkov's idea of the missile boat! The wheel has turned full circle.The LCS is the navy's version of the JSF,too expensive,too hyped,too few to make an eventual difference. Both weapon systems will be swamped with overwhelming numbers.

Meanwhile,the sub acquisition by intl.navies goes apace,except for the IN! Let's hope that Jait-Ley will take quick urgent decisions in this matter.

Submarine update – Greece to finally get its subs, Algeria orders more from Russia
David Pugliese More from David Pugliese
Published on: June 29, 2014

Defense News has reported that Greece will complete construction of three Type 214 diesel-electric submarines at Hellenic Shipyards, ending a decade-long dispute between Greece and Germany. In 2000, Greece signed a deal with Germany’s ThyssenKrupp for four 214 boats, but delivery of the first-in-class, Papanikolis, was delayed in 2006 when the Greek government refused to accept the boat.

The reason? Inspectors with Greece’s navy declared the submarine defective, with problems such as fuel cells overheating and excessive rolling in poor weather.

ThyssenKrupp countered that the assessment was actually a tactic to get a price reduction and away to the courts the aggrieved parties went.

Now there is an agreement – Greece will pay $102 million U.S. and the subs will be completed. Delivery of the first is expected this year, the other two in 2016.

Meanwhile, Jane’s is reporting that Algeria has signed a contract for the purchase of a further two Russian-built Kilo-class submarines, which will be expected for delivery in 2018. The boats will be built at the Admiralty Shipyards in St. Petersburg, Russia and will join four Kilo-class boats already in service with the Algerian Navy.

ThyssenKrupp agrees sale of Swedish submarine shipyard to Saab
BERLIN/FRANKFURT (Reuters) - Germany's ThyssenKrupp said late on Sunday it had agreed to sell its submarine shipyard in the south of Sweden to Swedish defence firm Saab for 340 million Swedish crowns (29.63 million pounds).

Saab had confirmed on Thursday it was nearing an agreement after business daily Dagens Industri reported that it might soon announce such a deal, with a price tag well below 1 billion Swedish crowns.

Saab and ThyssenKrupp announced in April they were in talks on the sale of the unit after the German group failed to reach a deal with Sweden for a new generation of submarines.

"The acquisition is in line with Saab's ambitions to increase its capacity within the marine area and strengthen the company's position as a full supplier of military systems," Saab said in a statement.

The transaction is not expected to have a significant impact on 2014 results, the Swedish company added, noting that ThyssenKrupp Marine Systems will be integrated within Saab's Security and Defense Solutions division.

Sweden had been seeking ways to share development costs with other potential buyers of its A-26 submarine but failed to agree on commercial terms with ThyssenKrupp, which also builds submarines in a separate business in Germany.

Sweden's government asked Saab earlier this year to come up with a strategy to support Swedish submarine naval forces.

Defence analysts saw the move as opening the door for the Swedish company to build submarines instead.

ThyssenKrupp Marine employs around 1,000 staff in Sweden, mainly in the southern Swedish cities of Malmo and Karlskrona. The Marine Systems unit, which also makes naval ships, posted sales of 1.33 billion euros last year.

US Navy awards Northrop Grumman multiyear contract for E-2D
The US Navy has awarded Northrop Grumman a $3.6 billion multiyear contract to provide 25 E-2D Advanced Hawkeye airborne early warning and control (AEW&C) system aircraft.

Announced on 30 June, the acquisition will bring the total number of USN E-2Ds on order to 50, out of a total requirement for 75 aircraft.

Thirteen production aircraft have been delivered to date, and initial operating capability is expected late in 2014.

The E-2D is a carrier-based AEW&C platform, which includes a rotating rotodome offering 360˚ surveillance and a four vertical stabiliser tail configuration.

“A multiyear procurement of these additional E-2Ds will take advantage of efficient, stable production lines at both Northrop Grumman and our suppliers, and will generate significant cost savings for taxpayers and the navy,” Bart LaGrone, vice-president of E-2/C-2 programmes at Northrop Grumman, says in a statement.

LaGrone adds that since the first delivery in 2007, every E-2D has been delivered on schedule and on budget. “It is this kind of proven program performance and partnership with our customer that results in a multiyear contract – validating that the E-2D Advanced Hawkeye is the right system at the right time for the right cost,” he says.

The E-2D was derived from earlier models of the AEW&C platform, with the current model including a more powerful APY-9 radar, as well as new avionics and a glass cockpit.

The VAW-125 squadron, based out of Norfolk, Virginia, is the first established E-2D squadron. It unit assigned to Carrier Air Wing 1, and operates from the USSTheodore Roosevelt.

while 1 or 2 existing DDG51 vessels could have been gutted to test the new techs piecemeal, stuff like that huge radar , elec systems and the AGS would need massive changes so probably not worth it to destroy a working ship for that. so choice between building new test ships or DDG1000 why not just build a few and get some real world exp on the hull as well. helps the local shipbuilding industry like bath iron works, maine.
They did try it out in the lab to a degree which has given them confidence to move ahead. If this basic design, architecture, conops is going to find its way into future designs, it has to be tried out on an operational scale, and the zumwalt is doing just that. Its not like these systems are going straight from the drawing board into a ship, the tech (radar, electric management, hull design) has been taken out of the so called lab through multiple R&D efforts.

Pentagon tester questions Navy ship's survival in attack
By Tony Capaccio, Bloomberg News Bloomberg

11:20 p.m. CDT, July 9, 2014

WASHINGTON — The Navy's $23 billion Littoral Combat Ship is less able to survive an attack than other U.S. warships, according to the Pentagon's top weapons tester.

Revised standards adopted for the vessel intended to operate in shallow coastal waters "continue to accept the risk the crew would need to abandon ship under circumstances that would not necessitate that action" on other vessels, Michael Gilmore, the Defense Department's director of operational testing and evaluation, said in a letter to Sen. John McCain, R-Ariz.

Gilmore, rebutting the Navy's contention that he's misstating the ship's requirements, said they are "significantly different" from those for other ships that may face enemy forces. His stance adds to previous questions about the future of the vessel being built in two versions by Lockheed Martin and Austal.

Defense Secretary Chuck Hagel said in February that he was limiting purchases to 32 vessels, instead of the 52 originally planned, until the Navy developed alternatives for a more survivable ship. He has called for a more "capable and lethal" option that could include an upgraded Littoral Combat Ship or a different design. Recommendations from defense contractors are due by the end of this month.

About $12 billion has been appropriated by Congress so far for 20 vessels.

In addition to $23 billion to build the ships, the Navy would spend $7.2 billion to buy mission modules that are supposed to be swapped out for mine-hunting, surface warfare and anti-submarine missions.

Gilmore offered his observations about the Littoral Combat Ship's survivability in the June 26 letter to McCain, who is critical of the program. The senator sponsored a provision in this year's defense budget that mandated a Navy and test office report on the ship.

Gilmore also submitted a report dated June 26 outlining the ship's evolution and the status of its warfighting equipment.

The letter to McCain was intended to rebut material the Navy submitted to lawmakers on June 6. It said Gilmore's office "inaccurately defines LCS capabilities" and "mis- characterizes the requirements to which LCS was designed" and its capabilities.

The LCS, "for military and survivability features, was constructed in accordance with Navy specifications and standards comparable to all surface combatants," the service said.

Chief of Naval Operations Admiral Jonathan Greenert said in a June 6 letter transmitting the service's congressionally mandated report on the ship that its survivability depended on a "total-ship concept."

The design will allow the vessel to "continue to perform its primary mission, exit the battle area under its own power or conduct an orderly abandon ship," depending on circumstances, Greenert said.

"In short, LCS is a survivable ship," Greenert wrote Rep. Rodney Frelinghuysen, R-N.J., who heads the House Appropriations defense subcommittee. "Speed, maneuverability and modern weaponry aid LCS in avoiding a hit in the first place."

"If hit, LCS was designed to minimize vulnerability" and "with modern automated damage control systems" it will be able to "recover from causalities and withdraw to fight again," Greenert said.

The Navy also outlined the five-year record of equipment failures for the USS Freedom built by Bethesda, Maryland-based Lockheed and the USS Independence built by Henderson, Australia- based Austal. It said the number of reports for each ship "is on average consistent with other surface combatants in the fleet," the Navy said.

Gilmore wrote McCain that the Freedom and Independence were built to a standard for vessels such as patrol and logistics ships that are "not expected to be survivable in a hostile combat environment and are not intended to be employed in a manner that puts them in harm's way."

"Combatants have traditionally been required to meet much more stringent survivability criteria," Gilmore said.

The Littoral Combat Ship's 50-member crew -- an increase of 10 over the original manning concept -- "should be able to extinguish small fires and control minor damage" from a "minimally damaging weapons hit or collision but might not be able to restore full combat capability at sea," Gilmore said.


Even with its advanced firefighting capability "the crew will likely be unable to fight a major conflagration and would probably be forced to abandon ship," he said

The People's Liberation Army Navy has deployed three nuclear-powered ballistic missile submarines to its South Sea Fleet base on the southern island province of Hainan, according to the Manila-based InterAksyon news website in a report published July 8.

The Chinese navy displayed a photo on the internet which suggested that three Type 094 Jin-class ballistic missile submarines are currently stationed at the Yulin naval base in Hainan, according to the report. The paper surmised that the three submarines are there to enhance the power projection of the Chinese navy in any potential conflict against Vietnam or the Philippines in the South China Sea.

This may indicate the launch of regular sea patrols by Chinese missile submarines in the South China Sea from Hainan, according to the Washington Free Beacon. Samuel Locklear, US Pacific Command chief, told the website China's submarine force is large and very capable. Locklear told the US House Armed Services Committee this March that the PLA Navy will likely have a credible sea-based nuclear deterrent by the end of 2014.

China also has two Type 056 Jiangdao-class guided missile corvettes stationed in Hainan. The vessels, equipped with surface-to-air and surface-to-surface missiles, as well as a 76mm main gun and two 30mm cannon will begin to patrol the disputed waters as well, posing a threat to the operations of the Vietnamese and Philippine navies in waters near the disputed Spratly Islands.

PLA YJ-12 missile the most dangerous threat to US Navy: US expert
In an article written for the Washington-based military website, War on the Rock, Robert Haddick, an American military analyst said that the People's Liberation Army Navy's YJ-12 anti-ship cruise missile is the most dangerous threat to the US Navy in the Western Pacific.

On page 40 of the Military and Security Developments Involving the People’s Republic of China 2014 published by the Pentagon for congress indicated, this cruise missile provides an increased threat to naval assets, due to its long range and supersonic speeds. In addition, the YJ-12 is capable of being launched from PLA Navy Air Force's H-6 strategic bombers. Haddick said, therefore that the YJ-12 poses more of a risk that the DF-21 anti-ship ballistic missiles.

Citing a study conducted by the US Naval War College in 2011, Haddick said that the YJ-12 has a range of 400 kilometers. This makes the YJ-12 one of the world's longest-range anti-ship cruise missile. Haddick said that the range of the US Navy's Harpoon missile is only 124 kilometers. The extended range allows the PLA Navy's aircraft to launch the YJ-12 beyond the engagement range of the Navy's Aegis Combat System and the SM-2 surface-to-air missiles that protect US aircraft carrier strike groups.

The missile can be even more dangerous when they are deployed in Su-30 and J-11 fighters from the PLA Navy's two Flanker regiments. With a combat radius of 1,500 kilometers, the Chinese fighters can carry between two and four missiles into the battlefield. Haddick said that the US carrier strike group will have to defend itself against over a hundred supersonic ASCMs approaching from several directions at a wave-top height, allowing the group's close-in air defenses less than 45 seconds to respond.

PLAN is reported to building the next gen of its SSBN after finishing the 3 Jin class(12 SLBM) class. this new class is reported to have 24 tubes which would make it 18,000t ohio class size. since their plan is to patrol and launch from bastion areas only given the overwhelming number of USN subs prowling around, this is a economical approach to putting more tubes under the water on fewer boats.

U.S. Navy Discovers That Sailors Need Sleep
The idea was that automation would enable fewer sailors to operate the $400-million LCS for all these missions. This saves on manpower costs as well as on precious shipboard space for crew accommodations.

But a new Government Accountability Office report proves what any Burger King worker already knows—cutting your workforce by 80 percent without also decreasing its workload … isn’t always a great idea.

When the GAO studied USS Freedom’s recent 10-month deployment to Singapore, the auditors found that crews worked too hard. “Freedom crews averaged about six hours of sleep per day compared to the Navy standard of eight hours,” the GAO stated.

“Some key departments, such as engineering and operations, averaged even fewer.”

And this happened despite the Navy temporarily adding 10 extra sailors to the crew and sending contractors aboard.
