The appointment of Ad. Joshi as LG of the A&N islands is a very welcome step.He fell on his sword as chief,taking the responsibility for multiple accidents involving IN ships and subs.These were in the main due to an utter neglect of the IN (and services in general) by the former Def. MIn.AKA ,"The Saint".Under Anthony's dereliction of duty,critical spares like batteries and other spares for our 25+ yr old subs and other warships were if at all ordered ,came late in the day.This is a v.good gesture by the GOI in rewarding a fine naval chief who had to suffer the neglect of his service by the DM.

The appointment is also v.interesting because of the critical geo-strat. location of the A&N islands,at the entrance/exit of the Malacca Straits to and from the Bay of Bengal/IOR. Beefing up the naval bases and mil. capability/defence of the islands is critical to the defence of the mainland,ensuring Indian merchant shipping safety,esp. in view of the PLAN's "pearl of strings" in the IOTR through its acquired base.logistic facilities in Djibouti,Htota in SL,BDEsh and Burma.and naval/air base at Gwadar in Pak.

Visited INS Kolkata today. Beautiful ship! Got a good tour. Decks and bunks were spacious. Good 55 inch Sony LED TV with PlayStation in Wardroom. Not at all claustrophobic. Even got a big tread mill!

Now can we order more P28s please? :roll:

http://defencenews.in/article.aspx?id=383879

Garden Reach Shipbuilders and Engineers (GRSE), under the Ministry of Defence, which recently completed major modernisation of its infrastructure facility and has doubled its capacity, has become the first Indian shipyard to build warships using carbon fibre composite material.

An official said integrating the carbon composite superstructure with the steel hull has helped reduce the total weight of the vessel and has increased its stealth capability. The Kolkata-based shipyard has incorporated this technology in its ongoing project of third and fourth ASW (anti-submarine warfare) Corvettes being built for the Indian Navy.


Imported material

The carbon fibre material, imported from Swedish stockyard Kockumo, is reportedly lighter than stainless steel, which is traditionally used to construct warships.

The official added the composite material was used to construct the superstructure of the ship, which would ensure that the vessel is 30 per cent lighter.

In the ASW Corvette, stealth is a key ingredient, said the official, and the composite material would help make it less susceptible to detection.

In a record for a ship of her size, the third ASW Corvette has successfully completed Contractor’s sea trials in the first sea sortie itself, while the final machinery trials for the vessel have also been subsequently completed.

The company had won the contract for four anti-submarine warfare Corvettes.

The first two ASW Corvettes, INS Kamorta and INS Kadmatt, delivered by the shipyard to the Indian Navy have been generating interest across the globe.

There was a report that the P-28As would have enhanced weaponry,etc. A criticism of these large corvettes,actually light frigates,is their lower capability/t than other surface combatants. They also cost a lot.However,if another 8 P-28As are built ,all in one concerted go,huge coist savings could be obtained. The problem is that the MOD issues out orders in dribbles,just a few platforms at a time,which gives the yards a feeling of insecurity,always having to kowtow to the MOD babus for more orders,developing ulcers in the bargain which makes them also raise the unit cost not knowing how long the programme will run. At least in the LCA prog. the MOD/GOI has ordered/approved 40 MK-1s and 83 MK-1As and the IAF has gone on record saying that "it would buy as many that are built"!

GIven the expected large proliferation of Paki and Chin subs in the next decade in the IOR ,the PN with 4 upgraded Agostas plus 8+ Yuan subs,plus a goodly part of the PLAN's 80+ subs,both N-boats and conv. /AIP boats,ASW will be the principal threat/task of the IN. For this the IN requires a holistic plan to win the UW war.LRMP aircraft like more P-8Is,med. MP ASW aircraft,ASW capable amphibs,and ship-borne ASW helos will be reqd. in v.large number (around 200),when one knows that at least 3 platforms are reqd. to detect and track a sub.That's just the air assets reqd.

A large no. of subs,both N-subs and conv. AIP subs are reqd, to track every enemy sub ingressing into the IOR,those permanently based in it,like PN subs and PLAN subs based at Gwadar,etc.plus hose reqd, to execute our forward offensive/defensive screen in the ICS and beyond.
As we know,the weak link in the IN is its sub fleet,v.old and whose numbers operational have drastically shrunk. This is the top priority and the IN must maintain a balance between large numbers "quantity being a quality in itself",by adding to its fleet of conv./AIP subs to enable it to saturate IOR waters and have a few engaged in forward ops.Cost here is a major factor.We should build at least two/three classes of HUK and LRCM capable subs of designs from both east and west.A western follow-on to the Scorpene and old upgraded German U-boats,and a Russian follow-on to the Klios which even after their second upgrades will start retiring from 2025 onwards.The 6 Scorpenes should be considered as U-boat replacements with another more capable western design built at MDL.

Then the req. for as many surface platforms as possible. Smaller ASW corvettes will be more affordable and available in large numbers to prosecute enemy subs.We have a plan to build 16 shallow water ASW corvettes of around 750t+ as well.While these are v.useful assets in guarding our ports and naval bases,PLAN and PN subs today have sub-launched missiles of ranges from 200-300km ,therefore the need for ASW assets like the P-28s which can conduct ops in our EEZ and even blue waters .
The Khukri/Kora class corvettes are also to be upgraded and it would be worth equipping them with better SSMs as well as ASW weaponry.Equipping the CG's OPVs with some ASW capability is another must. Our exg. Abhay/Pauk ASW corvette class of just 450t,based upon the same hull as Tarantula missile corvettes,is v.long in the tooth,but contains a lot of ASW weaponry,TAS,etc. We must leverage all surface vessels of 450/500t and above to possess some ASW capability which would prove to be v.useful during a crisis.

PS:Pak's new Chinese subs are expected to be able to carry the naval Babur equiv. LRCM plus 3-4 BMs too in one poss. config. This would be the poor man's equiv. of an SSBN. IT would make more sense for Pak to follow this route also being adopted by Israel for its second-strike capability. Should we also possess a large number of AIP subs,we could have one class equipped with 8/10 BMos missiles or even Nirbhay,N-tipped,to serve as extra second strike capability against Pak principally,using our 5-6 SSBNs of the Arihant class meant for China.

What is the logic of putting Klub on older ships and Brahmos on the new ones? Is it cost or is there some other rationale?

One is cost and the other is dimensions, remember most of the missile launchers on these ships were for Uran missile, the Bramhos is much larger missile than klub and would require significant redesign of the ships.

Until BMos-L/NG whatever nomenclature is used arrived,which is smaller and can be fired from std. torpedo tubes,Klubs will be reqd.Klubs may also be much cheaper and have proven themselves in Syria where the ER Kalibir variant has had a huge impact fired from small corvettes from the Caspian Sea too.

They're actually of a similar size though the BrahMos is about a third heavier.

I knew this for a while now (through a relative), but kept it to myself till the news became public.

Initially, the plan was to have an all steel ship. However, the weight crept up and the top also became slightly more heavier than they liked. That's why they went in with an all composite superstructure. It was not for stealth. But, this was the primary reason for the delay in building the ships. To limit the delay further, they decided to continue with the steel for the first two ships as their build was well underway, and switch to composite for the next two ships.

Consequently, the last two P-28s is as good as it gets. They are super quiet and the top half is composite. Because the top part is lighter, they have great sea-keeping qualities. That's why you see these accelerated testing.

^ I think extensive use of sheet metal for stealth shaping and housing has lead to weight increase on all ships. The most noticeable difference is on Kolkata class, versus Delhi class which share the same hull.

Nothing official unless GOI confirms , Could easily be minor incident than accident , Subs have hit and damaged sonar dome and it is NOT a major issue to fix its a composite material that dome is made of that covers the cylindirical sonar but if it hits the pressure hull then it would be out of action for some time again assuming this news is real to start with.

First, exact damages unknown. Submarine is not a write off. There has been no cataclysmic nuclear incident (Touch wood!) and well repairs and maintenance of submarines are costly. So, what is unusual here and where do we owe Ruskis a nuclear sub now, hainji?

Now calm down, take a deep breadth and thank god that bad news stopped at submarine damage. :)

Vidur, Can you ask for an Integrated Enterprise Shipbuilding plan for the various vessels for the navy?
A plan that integrates the major ship yards: Cochin, Mazgoan, Garden Reach, Hindustan Shipyard and Goa shipyards.
Add the private shipyards to the mix. I feel its ad-hoc thing going on.

Maybe major combat ships plan as first cut:
Aircraft carrier, conventional sub and nuke subs, capital ships?


It will be an eye chart but one chart that shows the milestones, spans and major hand offs.

And no need to share with mango public.


chola, Would recommend restraining yourself.

I don't believe there is any integrated plan - the current ownership and ownership history of different shipyards are not equivalent. For example HSY was a failing private sector yard which was bought by the government. While the logic given was the nuclear submarine project the rumor mill said that a MOS for Defence in the previous dispensation was a key mover. The primary defence shipyards are MDL and GRSE. The others are not really defence shipyards.

There is some method to the madness in allocating orders. MDL has the most experience and capability followed by GRSE (which has sort of risen like a phoenix in recent years). So its natural that MDL and GSRE get orders. CSY just has the size to build very large ships so naturally Vikrant is being built there. Building the (yet to come) minesweepers at Goa was a politcial choice. Pipav did not help the case of private shipyards in delaying their share of the NOPV project.

But the sad part is that L&T shipyard is lying waste. It is a shame that pvt sector makes huge investments and shows commitment but we end up protecting the current set up. It takes us almost 10 years to make a destroyer in even yards like MDL. I am sure GOOD private shipyards can do it in half the time. Perhaps that is why we never give them a chance.

Re a major combat ships plan, there are many and have had CCS approval also. P17 A was approved in 2013 by CCS ? Submarine building plans also years ago. So you can have all the combat ships plans and 5 year defence plans you want. But it doesn't matter because REAL financial sanction only comes thorugh annual budget and at that stage its a catfight and very adhoc.

Do read the second article I linked in LCA thread.

Saar, check this out...

Composites 101: Fibers and Resins
https://www.compositesworld.com/article ... and-resins

Aramid fibers, formed from aromatic polyamide, provide exceptional impact resistance and good elongation (higher than carbon, but less than glass). Standard, high-performance aramid fiber has a modulus of about 20 Msi, tensile strength of approximately 500 ksi and elongation of nearly 3%. Renowned for its performance in bulletproof vests and other armor and ballistic applications, aramid fiber has been in demand in part, due to the need for personnel protection and armor in law-enforcement and military markets. Aramid’s properties also make the fiber an excellent choice for helicopter rotor blades, marine vessel hulls and sporting goods where impact resistance is desired.

Years ago we got a good look at a Sov. Victor class sub (?) involved in an accident I think in the Meditt. off Gibraltar.The bows were badly damaged and one could clearly see the double-hull structure and damaged sonar of the Sub. Had there been a similar accident it would've been v.difficult to conceal. Let's hope that only the sonar dome was damaged and if at all ltd. damage to the sonar.

Great explanation of our warship building landscape. But the non-/mis-use of our private sector is totally infuriating. One of the reasons I was/am a supporter of the F-Solah tie-up with Tata (in spite of what it means to the LCA) is the hope that it can change things by bringing in the private sector in a disruptive way.

Why do you think it would be difficult to conceal if anything happened in open seas given that literally nothing about the Chakra is ever made known to the public?

Sat and other pics from other vessels. Any damage topside would be difficult to conceal.Take the US warships involved in collisions. Say for example if the sail was damaged,the sub would not be able to submerge and ,like the NDTV v-clip when the Arihant sailed out for its ea trials,would've been captured by some news entity.MOst likely as hinted,that the sub scraped the bottom of the channel.Old report below.

http://indianexpress.com/article/india/ ... g-channel/
The Navy’s run with accidents involving its frontline warships continues with the country’s most modern amphibious battleship running aground while returning to Vizag naval base after a regular patrol last week. INS Airavat, the latest of the Shardul class of tank-landing ships, has suffered damage to its propellers.
The warship is now set to undergo significant repairs to its propellers and likely to be docked over the next few days to assess the damage and to carry out a refit.

These two amphibs are approx. 20,000t and are are a mere 20 yrs old.We've generally used our warships for almost double that time,so these ships should have at least another 15 yrs. life in them.Look how we used the Hermes/Viraat for 25+ years!

Royal Navy could lose 'beach-landing' ships in next round of defence cuts

The Royal Navy could be stripped of its ability to attack enemy-held beaches under cost-cutting plans.

The Senior Service could see its two amphibious assault ships, HMS Albion and HMS Bulwark, taken out of service in a new round of cuts to the Armed Forces, the BBC's Newsnight claimed.

It said such a move, which the Ministry of Defence described as "pure speculation", would save money and free up crew for the two new aircraft carriers, HMS Queen Elizabeth and HMS Prince of Wales.

It comes days after Sir Michael Fallon, the Defence Secretary, used a speech at the Conservative Party Conference to call for an increase in defence funding as his ministry announced a £1billion support package for the Royal Navy fleet.

Newsnight reported that the plan, coupled with the loss of 1,000 Royal Marines, had alarmed senior commando officers.

The loss of Albion, a former flagship of the Royal Navy, and Bulwark would leave the Navy without a dedicated amphibious assault ship.

Beach landings in areas where the enemy controls the harbours have been used in many modern conflicts.

In his speech on Tuesday, Sir Michael said the Armed Forces must "modernise" the way it worked.

He said that as threats "intensify", his department was "now looking right across government to make sure we are doing enough, spending enough, to properly protect our country against all of those threats - cyber, hybrid warfare, rogue states, terrorist attacks."

An MOD spokesman said: "In the face of ever-changing threats, we are contributing to the cross-government review of national security capabilities and looking at how we best spend our rising defence budget to support that.

"No decisions have yet been made and at this stage, any discussion of the options is pure speculation."

India’s only nuclear-powered submarine damaged

India’s only nuclear-powered submarine ‘Chakra’ has suffered “some damage” in an accident and could require substantial repair work to get it back in shape.

The attack submarine, obtained on a 10-year lease from Russia, has not sailed for a month and is berthed at its home port of Visakhapatnam for repairs.

According to The Print newspaper, the submarine — currently India’s only operational nuclear-powered vessel — suffered damage to its sonar dome in the accident. The sonar dome is located at the forward portion of the submarine, beneath the torpedo tubes.

While details of the incident are yet to emerge, the newspaper said the damage could be the result of either a collision at sea or accidental scraping while entering the harbour. The Indian Navy refused to comment on the incident, reported The Print.

Repair work on the submarine is likely to be complicated given that the sonar dome is made of titanium, a difficult metal that requires both specialised machinery and manpower to work on. However, the indigenous Arihant nuclear-armed submarines are also being made in Visakhapatnam and that could help. The Visakhapatnam harbour has recorded incidents in the past when warships have touched the bottom while navigating the tight water channel. In January 2014, the INS Airavat — a Shardul class amphibious warship — suffered damage to its port propeller while entering the harbour. Inducted in April 2012, INS Chakra is a modernised Russian Akula-II class submarine, known as one of the stealthiest in the world after American vessels of similar class. While the submarine is nuclear-powered, it does not carry nuclear-tipped missiles on board and is designed to be a silent killer — it lurks underwater to sink enemy ships and take out land-based targets.

The stealthy nature of nuclear-powered boats, along with the increasing traffic at sea, has meant that accidents have become common. At least two such accidents had taken place last year itself.

In July 2016, a British nuclear attack submarine, HMS Ambush, collided with a merchant vessel off the coast of Gibraltar suffering external damage. A month later, the USS Louisiana nuclear missile submarine collided with a naval support vessel at sea, suffering damage to its starboard hull.

The story behind the Chakra is that it was taken on a 10-year lease in 2012. The Chakra has a displacement of 12,000 tonnes. It is powered by a 190 MW reactor and can reach speeds of over 30 knots. The vessel is manned by 80 crew members and is equipped with tactical missiles, a new fire control systems, sonars and contemporary optronic periscopes and surveillance systems.

Originally named the Nerpa, the submarine was launched in 1991 but was mothballed after the collapse of the Soviet Union. India later took it on a 10-year lease for close to $1 billion. India is now moving ahead with its plans to lease another nuclear attack submarine from its old ally Russia for an estimated $2.5 billion that will include the refit of the boat at a Cold War era shipyard, followed by a 10-year deployment with the navy. The new ship is likely to be inducted after the completion of the lease period of Chakra.

Delayed again? Delays due to absence of torpedoes is entirely the MOD's fault,blacklisting all group cos of AW instead of just the helo division/co.
Sea trials requiring some glitches to be ironed out another matter.

India’s Second Scorpene Advanced Attack Submarine Misses Induction Deadline
Friday, October 06, 2017
By: SPUTNIK News
India's construction of a second Scorpene submarine, the INS Khanderi, is more than five years behind schedule. Its induction into the fleet has been repeatedly postponed; most recently following the cancellation of a deal for the purchase of torpedoes.

India's Scorpene-class advanced attack submarine project has faced another setback with the second completed submarine also facing delays in sea trials.

The INS-Khanderi isd the second of the six submarines being locally built following the transfer of technology from French firm Naval Group (earlier DCNS). It was launched in January and was expected to be inducted into the Indian Navy by the end of this year, but hurdles in sea trials have made this highly unlikely. The induction of the first INS-Kalvari submarine has already faced several delays.

The Indian Navy recently announced a further delay in commissioning the first vessel, the INS Kalvari. “The Kalvari submarine has already been in the sea for some time now. Some 110 days of sea trials have been completed and more pre-commissioning sea trials are going on. We are expecting it to be commissioned by November-December this year,” Vice Admiral Girish Luthra said.

Mazgaon Dock Ltd (MDL) delivered the first vessel to the Indian Navy last month after it was put through a grueling set of trials lasting over 18 months, including successful live missile and torpedo firings.

Meanwhile, the second Scorpene-class submarine, the INS-Khanderi, has begun sea trials in the Arabian Sea following the end of the monsoon. The diesel-electric attack submarine was planned for induction by the end of this year. However, sources say trials would continue for at least until the first quarter of next year. The Khanderi had begun its first sea sorties from the port of Mumbai in June this year.

India’s state-owned Mazgaon Dock Ltd is building six Scorpene-class submarines for the Indian Navy at cost of more than $4 billion under the technology transfer agreement with French firm Naval Group. India and France signed the agreement for the project in 2005.

The six submarines will be capable of firing the French-made Exocet SM39, a sea-skimming, subsonic anti-ship missile with an approximate operational range of 50-70 kilometers. The Kalvari is equipped with six 533-millimeter torpedo tubes for launching anti-ship torpedoes, anti-ship missiles, and sea mines.

However, the first two submarines, the Kalvari and the Khanderi, have yet to be equipped with their primary weapons: heavyweight torpedoes. The Indian government had to cancel an order of WASS Black Shark torpedoes due to alleged corruption in the deal.
The Indian Navy presently commands a fleet of 121 ships, 14 submarines, and 232 aircraft. The actual requirement is far higher, with a target of 198 ships and submarines by the year 2027.

Nice! A Talwar class in action. I hope we get videos. I need to stuff them in the faces of a few Pakis.
