On the way to the galley, Suresh turned the knob into a room that is full of computers and finds a packet of food on the floor. Two officers and four sailors are inside. “Let this be the first and the last time anyone eats outside the dining halls in the ship,” Suresh said.



Computer wiz are the same everywhere... :rotfl:

In future the Navy is looking to have a data exchange system with the IAF’s Airborne Warning and Control System (AWACS). A system is being integrated with the AWACS to provide data that may be out of the range of the ship. This will provide an edge in firing of weapons.

Why to burden the IAF AWCs with full time IN duty?

Cant the IN also order a few Phalcon based AWACs? This would ensure commonality also

As a result of major slippages and Mazagon Dock's inability to absorb certain technologies expediently -- but mostly through shoddy forward planning -- India's first Scorpene will only be delivered in the second half of 2015, instead of 2012. Scam or incompetence?



The MDL chief in "n"i number of interviews given to Force mag has insisted that Scorpene will be ready by 2012 , now that GOI has confirmed it would only be ready by 2nd half 2015 , Wonder if any action will be taken against MDL bosses.

Holy $@#%!...

We will actually hit single digit number of (operational) subs if the first Scorpene is to roll out in 2015!!! :( :(

Pranabji and his purse. Already there is a grave threat looming around with reports of Terror threat to Delhi. I don't know how he can do this to the Indian nation and the people. Do he thinks money in his purse is more important than people's security.

A video of the Ship generall purpose firing complex. An advertisment by the russina company which advertised the Club-k. The reason i am posting this in the mix of missiles that can be fired by these ships even brahmos is shown. The complex also looks similar to one installed on Shivalik. So our new baby must be capable of firing all these missiles from 3M-14E to brahmos and entire club range. A nice way of giving some decent land strike capability.

Man there is a lot more than that meets the eye.

If we can extend the range of brahmos a bit and in coordination withe our Recon sats should give decent Land attack capabilites. i Hope even the new sagarika fits the same launch complex.

Philip,
I agree with your suggestions psychology oriented designs, non shatterable fixtures and fixed furnitures and they also have to avoid sharp edges. I noticed sharp plywood designs in a pillar from photos in Chhindits blog notified by another reader in Ajaishukla's blog.
However, what is worng with the suggestion that drilling a hole in the helicopter's hangar. Acecpted that it is an unconventional way. Such option should not be chosen, if it affects the safety, security or capability of the ship. However, if the hole did not affect the operational part of the ship why such option should not be employed? Also plz enlighten me, if you are aware of any reasons.

This is just a publicity stunt. She is just trying to prove that her blog is better than the other blogs like livefist or ajaishukla by saying she has pics of arihant. I am sure she hasn't invited anyone, because if she would have then the pics would be in public domain by now.

I was just pondering over how the naval strategies and surface combatants have evolved from Yamato class IPN BS. Those beasts were amazingly loaded but convincingly beaten by air power and submarines.

What an interesting line of thought, but do educate this unwashed Abdul as to its relevance to the discussion. Are you comparing the P17 to the Yamato? Or IN's surface fleet in general?

A few more questions for your perusal, since you mention air power and submarines:
    What was the Yamato's ASW sensor and armament fit?
    What was the Yamato's air defence sensor and armament fit? How many of her AA cannon were radar-directed? What were the salient issues faced by her 'Beehive' AA ammunition, which were 460mm fragmentation shells that were fused to explode in the path of incoming attackers?
    What was the standard Task Force that Yamato was to be a part of? Ideally, would it include carriers, ASW destroyers, etc.? If yes, then could you describe the composition of her accompanying TF when she was sunk?

In today's IN, or in fact an navy of note, no ship-of-the-line is as skewed towards a single role as the Yamato. Primary surface combatants have a good mix of AAW, ASW and AShW sensors and weapons.

If you're going to ask "how the naval strategies and surface combatants have evolved from Yamato class", then do so in the newbie thread, not during a discussion of the P17. Your question either betrays a certain ignorance or comes across as being a highly suspect insinuation.

Cutting Edge
Deccan Herald
'Shivalik is a symbol of India’s capability.'

INS Shivalik’s commissioning into the Indian Navy is a matter of pride for India. It is India’s first indigenously-built stealth frigate. With its commissioning, India has joined an exclusive club of seven other countries that have the capability to build stealth warships. India has other stealth frigates but with Shivalik, it has a state-of the art one that carries a made-in-India label. The Indian Navy and India’s shipbuilding industry have displayed admirable capability in design and building of a new generation stealth frigate with futuristic technologies. This is undoubtedly a major accomplishment and a feather in the cap of India’s engineers. Shivalik will give the navy an important edge. It can be seen, no doubt, but cannot be easily detected by enemy radar. Every surface of the ship is so constructed to deflect radar signals.

Shivalik’s stealth will allow it to sneak up to the enemy undetected and destroy him with a range of high-tech weaponry it carries on board. And it is armed with sharp teeth, indeed. Shivalik is equipped for nuclear and chemical battles too. What adds to Shivalik’s value is that its designers have kept the comfort of its crew in mind while conceiving it. Unlike other warships which expect sailors to make do with tinned food and cramped living quarters, Shivalik will provide our naval men (and women) edible food and decent living quarters.

Shivalik provides pointers to how India’s military hardware is evolving. This stealth ship is made in India perhaps but it also carries systems and components from countries like the US, UK, Russia and Israel. This serves as a reminder that to emerge as a formidable fighting force, India should draw on the best of Russian and western technologies, in a way that best suits its military needs and strategy.

Excessive Dependence On One or The Other Country to meet our Defence Needs is not in India’s Best Interests.

Doubts have often been raised about India’s capability for defence production. DRDO is often derided as a ‘white elephant’ which has consumed funds and has little to show for it. Indeed, its projects have suffered from horrendous cost overruns and delays.

In sharp contrast India’s shipbuilding industry has scored several successes and Shivalik is among them. This is a world-class stealth warship at Indian prices.

India has the potential to emerge as a global shipbuilding powerhouse. Shivalik is a concrete symbol of that capability.

Good point.In fact the P-17 and P-28 designs can be hawked for export to friendly countries.The P-28s in particular,being smaller and cheaper,would be very useful vessels in any navy.Our biggest problem is construction time and any potential buyer,looking at our track record,will hesitate to order unles it is backed up by the GOI (with penalty payments for delays) to the hilt.The IN's warship design team has come of age with the Shivalik's commissioning ,which is a warship as I earlier detailed,very competitive capability and cost wise.

While largely true, I have to disagree a bit. Our radars are still not top notch. We need to go the A/P ESA multi beam way and clean up multiple radars and directors to have the nice clean smooth topsides to have full integrated stealth. That probably will come only in the next gen warships. The day we get out of the Fregat/Top Plate, Garpun B and individual STGRs into one AESA with multi beam and built in redundancy , we can probably clean up the second mast like in the P17, go with a one masted layout and probably free up quite a bit of space and equipment with better packaging and build further capability into the ship.

I would think the stuff that is longest in the teeth are the Shtil systems. Air defense is probably where we still are a bit weak. They probably will be replaced by VLS Barak-8s when it is ready in the bulk of the IN fleet. Oh, the Sthil launcher seems to have that "cage" in IN service, even INS Delhi seems to have that cage.

The Russian radars are probably much cheaper than the Euopean ones and deliver the goods,especially as some Russian weaponry is also aboard.Though for "full stealth" one would expect conformal sensors within masts,etc.A mix of Russian/Israeli/Indian andti-missile hard and soft kill weaponry actually enhances the design,as we saw during the last Lebanon War,the Israeli Barak armed missile corvette,the Haanit,was almost sunk by a Hiz Chinese anti-ship missile.

it is possible to go for a unified search cum missile guidance radar only if all of ASM, SAM, SR-SAM and combat system are from one source.

top plate + shtil + klub + barak + BEL EW + EL-20xx + desi combat system dont make a homogenous mix.

in P17A the chances are better:
MF-STAR-ER (which should have considerable search function + Barak8 guidance)
the barak1 STGR shall likely remain as it provides extra redundancy in case main radar is shut down vs ARM attackers
Brahmos probably doesnt need any radar at all, just a radio link for mid course updates? (for that matter I thought garpun bal
was for uran only, how come Klub has it?)
they will likely retain the search radar on rear mast as a insurance policy and because with a SMART-L sized antenna search
ranges in excess of 500km are possible (as Type45/horizon/sachsen does) vs 350 kmish with mf-star flat panels.
the Oto-breda main cannon will need some form of radar to track fall of shot (what is used today?)

I think rather than holy grail unification of the catholic , protestant and greek churches SPY3 style we should
aim for some distinct antennas but all conformal and flush with the masts.

getting rid of the shtil launcher with those ladders crawling up both sides and the high-RCS RBU launchers hidden
within a stealth turret with sliding roof are also low hanging fruit.

Its not a chinese anti ship missile it is Kowsar which is 100 kg anti ship missile made by Iran it uses IR sensor. Supposedly the Hanit was operating on radar silence and Israel was not expecting a non radar guided ashm. As for Hanit itself the ship did not come close to sinking it was lightly damaged and went back to port on its own. One thing to take away is IN needs to install EO sensors on its vessel to counter such threats.

the shivalik doesnt look too far behind the type45 in stealthy looks.

http://www.royalnavy.mod.uk/upload/img_ ... _final.jpg

t45 has a navigation radar sticking out in front of the mainmast and three small radars hidden under domes.
it scores with the empar dome vs the exposed top plate and the clean fwd deck with the "wall" around the aster30
array probably to keep out sea water in hostile storm waters of the north atlantic and artic sea.

and it sacrifices one helicopter for a brawny rear array of aster30.

I guess if P15A is to be true AAW ship we need to likewise giveup on one helicopter or both helicopters (keep a landing deck
like some burke's do but no hanger) and mount mf-star-er + 72 barak8 missiles + 32 barak1 SAMs + 4 x ak630-upg(with radar tracking of shells). only then it can truly provide cover to a task force and defend other ships.

Type 45 main advantage over P15A is that its mast is tall as result SAMPSON radar is placed relatively high allowing for better ranges against low flying target and not to mention its large S1850 search radar. Its armament is lighter than P15A only 48 Aster missiles and no Ashm vs 15A's 48 Barak 8s, 32 Barak 1 and 16 Brahmos plus torpedoes and CIWS guns which Type 45 will not receive till later on. It does have integrated electric propulsion system which hopefully IN incorporates for P15B.

Problem is , Chipanda and hence Pakis have access to the same radars and hence in some ways already "compromised".

Hmm. I was wondering if there is a Naval standard , equivalent of the USAF/NATO Mil-STD-1553 bus interface. If there is one, we should adopt it and standardize on it and buy weapon systems with standard interfaces. That way, no being held over the barrel by propreitary interfaces and standards by any vendor .. Roosi, Phrench, Isreali or whoever.

Critically, I think it is extremely important we get our act togehter in Radars and go the A/P ESA way, either indigenously or jointly with the Isrealis. We cant have crucial systems like that as "joint" assets with Chipandas and Pakis.

quite right - klub, fregat, shtil, ak630 are all with china and their strong and weak points from testing known fully to pakis. chinese
must have crawled all over the soveremeniy's too documenting even little things in detail.
except for our desi sonar, the Kilo class is also compromised being in service with PLAN in advanced 636 format. likewise all russian torpedoes. good thing we are making our own.

I think the P15A should keep the space in 8xBrahmos cells free and instead mount a light ASM fit of 8 x MM40 exocet in inclined boxes
amidships. this space should instead be kept for either enlarging the Barak8 carried or if ATBM mode is planned for the radar, then
AAD missiles.

unlike the US, we have ample scope to mount this 7.5m missile from land based TELs even in andaman so maybe we can leave ATBM
out of ships because the big length drives the need to make the ship deep and broad which drives up tonnage and cost.

Cant the type45 carry Aster15 in the same cells for close range defence? UK has little need for a AAW ship in the coming couple
of decades, and they could also cheaply mount some boxes of ESSM/RAM along the sides - its a big ship.

First Phase of Asia's Largest Shipyard by Next year
The first phase of the ambitious ship building and repair yard off Chennai, slated to be the largest in Asia, will be ready next year.

A joint venture of Larsen and Toubro and TIDCO {Tamilnadu Industrial Development Corporation}, the ship building yard was coming up at Kattupalli in Tiruvallur district. It would build very large cargo carriers, specialised cargo ships for liquid/gas transportation and cruise vessels, defence ships and submarines and off-shore platforms for oil/gas sectors.

It would also undertake refitting and re-engineering of commercial and defence ships and heavy engineering fabrication and components production for ship building.

It is the "length" that is the costliest part of a ship. Of course, if you make a warship fat and short, instead of long and fine, the resistance will increase. Yeah. You do have a point though, so for a given fineness ratio, more displacement will mean greater length.

Note.. Tonnage in ships is different from Displacement (which is the weight of the displaced water in tons.. and by Archimedes principle is the total wt of the ship). Tonnage actually refers to the internal "volume" of the enclosed spaces and is a measure of how much cargo by volume it can handle. In commerical ships, port and other charges are usually calculated using "tonnage".

"strike length" missiles of 7-10m length need very deep VL tubes going down 2 deck levels even if we have them protrude obne level up in a "brahmos style verandah" in front of the bridge.

ship will weight in around 9000-12000t to accomodate any decent number of such puppies - like say 24 or 32.

instead its cheaper to just go with 6500t hulls without ATBM and just base necessary number of land based launchers in places like andaman
which is only place where a sea based atbm makes some sense for us.

we first of all need a swarm of barak8 going out to meet any fixedwing or helicopter aeriel threats. the 60,000t carriers PLAN is building
will have a good strike punch.

thinking unlike Unkil in future a sea based deterrent could be mounted on a commercial tanker hull of the type Fincantieri is building for us.
put them in a maxtrix in the center or in rows all along the side. improve the damage control and fire fighting. these ships will come
prepacked with high degree of commercial automation and 25knot speed and long endurance. a austere CIWS of barak1 can be mounted
and a few ak630 for sentimental reasons. these ships have ample room for cranes to ease loading up fresh rounds in small docks without
shore support. a revathi type surveillance radar is good enough....a real warship would always be poking around nearby. sailing alone,
it will be hard to distinguish it from merchant ships sailing by the dozen.

a desi version of the container-klub concept. stack them up too if you want.

1. Chaff dispenser? Counter measures?

2. On the main mast, what accessory Radar is that?

3. What is that structure on the mast? An optoelectronic sight?

4. Also what are those microphone / light shaped objects along the sides and on top of the Helo Hanger?

5. Does the ship carry any soft-kill / non lethal weaponry like those noise makers that are on US ships?

EL/M-2221 STGRs for Barak-1

3. What is that structure on the mast? An optoelectronic sight?


Yes the EO sight below Top Plate and Reshmi or Rosy what ever they call its a Navigation Radar
PIN 524

4. Also what are those microphone / light shaped objects along the sides and on top of the Helo Hanger?


Just the normal lights for the hanger

5. Does the ship carry any soft-kill / non lethal weaponry like those noise makers that are on US ships?


Yes they should part be of normal Torpedo Softkill Countermeasures , there are no torpedo hard kill in there except for RBU

It carries both Aster 15 and Aster 30.

It's surprising that the type45 has no submarine attack capability whatsoever except torpedoes carried by the single embarked helicopter. It must be extremely confident of its sonar suite for early detection, and dependent on its sister ships. Quite risky, imho. Lack of ASW and weak ASuW means the type45 will probably never roam the oceans alone. For all its stealth and size, it will never frighten any enemy, however small (except if it plans to ram the enemy ship!). A destroyer that doesn't have any offensive capability is still a 'destroyer'?

I like the balanced approach that the IN has taken with its capital ships, giving them all-round capability. As for the perceived disadvantage of not having a dedicated AAW ship, since every major IN ship has decent AAW capability, the overall AAW strength of the flotilla will be equal, if not more, to a single dedicated AAW ship. In fact, such an arrangement has the advantage that it doesn't leave any quarter completely unprotected from any type of threat, and is not overly dependent on any single asset.

Singha,have you been following the latest Russian development of a "container" missile (Klub),that can be fitted onto any vessel and remain undetected? Since we already operate Kulb,it would be an excellent addition to our weaponry.The ingenious system would also be perfect for locating these container land defence missiles anywhere on the coastline/island territories,suitably camouflaged and virtually undetectable.In a crisis,we could similarly turn as mentioned,our merchantmen/fleet auxiliaries into lethal land-attack arsenal ships!

Tx John for the Haanit clarifications.If it was an Iranian missile,one can expect "interesting times" in the Gulf if Iran is attacked in the future by either Israel or the US or both.From available evidence,it appears that the Iranians are trying through assymetric warfare to swamp the Gulf with small craft,mini-subs and launch hundeds of missiles,both local and Chinese.It is going to be v.hard to counter such mass attacks at sea.

Austin garu,
Thanks for that clarification.

I was actually referring to this. On closer inspection of the mast I see several other sensors that are unidentified. Can you help?

I was referring to the crowd dispersal type soft kill measures - those directed noise producing devices that I believe US navy ships use (not the torpedo countermeasures)

Not entirely. 3 seems to be movable just like the Shitl-1 launcher.

But 1 is important enough to have its own place on the mast.

I wonder if these are counter measures - chaff / flares.

Interesting to note that all points where thermal signatures might be generated - Main Gun, around the missile launchers / SAM, Snootstack, there are water cannons which I think will spray seawater into the air and onto the hot areas to quickly suppress thermal signatures.

2 is a wide band jammer, not sure of the origin (Indian or imported). 3 is an EO device (more likely to be LLTV which is closed). I also think 1 to be some sort of ESM/ECM Sensor.

Gagan for first pics , 1 certainly looks like a jammer to me perhaps part of Sangrah EW suite to me a Multibeam Phased Array jammers. 2 from pics 1 is difficult to figure out its very vague
crowd dispersal type soft kill measure


I dont think we employ USN type crowd dispersal type soft kill atleast something I am not aware of , fire few rounds of AK-630M in the air the crowd gets dispersed :wink:

since the EO device is pointing to the rear I wonder if its a SIRIUS type missile detection type IRST(seen on dutch de zeven provincien ships) or merely a means to track the ships incoming helicopers at night without using any radar?

What is SIRIUS?

SIRIUS LR-IRST


SIRIUS is a passive LR-IRST system that operates simultaneously and continuously, scanning in two wavelengths (3-5 µm and 8-12 µm) under all atmospheric conditions and in environments ranging from the Arctic to the Equator. It is touted as a “next-generation system” with unique processing algorithms that ensure a low false alarm rate, and an effective range that extends to the horizon.

SIRIUS also provides high-resolution, panoramic video under day and night conditions that significantly improves situational awareness against multiple threats by automatically detecting and tracking targets which might otherwise go undetected by radar, especially if a ship is operating under low EMCON protocols. These threats include small surface targets, low flying aircraft, and anti-ship missiles. The TV images are especially useful for threat classification.

Unlike a radar, which has sometimes been described as a “flashlight in a dark room,” passive sensors avoid giving off detectable electro-magnetic emissions. This characteristic, plus its long-range capabilities, makes SIRIUS especially useful for covert surveillance.

Canada’s DND notes that:

“SIRIUS will be used for a variety of ship missions, including search and rescue, air operations, navigation and patrol.


El-op has a load of thermal sensors suitable for naval use. my guess is we fitted one of these.

Monica Gandhi will be most displeased!
AK-630M rounds must be Uber EXPENSIVE !
