The Indian Navy's principal surface combatant (PSC) fleet by 2027 as per current projections (existing + to be commissioned + to be decommissioned) - 3 x P15 + 3 x P-15A + 4 x P15B (Destroyers) & 10 x Talwar Class + 3 x P17 + 7 x P17A + 3 x Brahmaputra Class (frigates) ~33 PSCs

The Indian Navy needs at least 25 large frigates and around 15 destroyers. Basically a minimum of 40 principal surface combatants. It is time to indigenize the 'move' & fight components of surface warships as quickly as possible.

So, Dalals are now using the lunatic fringe to not just spread slanderous lies about me, but my wife @DevapriyaRoy as well. However, neither will we be deterred, nor can the rising tide of indigenization be stopped.

We already discussed il-38 are not cheap just to update them with sea dragon cost over 40 million each a decade ago now it will be over 100 million and god knows how much to restore these air frame from Russian junkyards.

All this for used up ac which don't even have a decade of service in them it doesn't take a genius to figure out P-8s are better value. If we are desperate there are plenty of Orions we can grab but even then P-8s are better choice in long run due to maintenance costs.

Rakesh · Post by **Rakesh** » 21 Feb 2018 03:20

Exactly John. Please no more IL-38s. We need more P-8Is. Order as much as the MoD is willing to loosen the purse strings for.

Philip · Post by **Philip** » 21 Feb 2018 03:45

P-8s 3-4 times more expensive.We will have to wait for a new platform then.Remember that the P-8 can't fly low and slow essential in prosecuting subs .Turboprops are better at this task, both types required.

Rakesh · Post by **Rakesh** » 21 Feb 2018 03:56

And IL-38s are 8 times more expensive to maintain and operate. So it balances out

So you say Philip Saar about the P-8 not being a sub hunter. However, evidence states otherwise....

Meanwhile, in the real world there isn't a single Amur class boat (with or without VLS plug) completed yet.

Amur class is dead, Lada is know more of poc and testing new technology that will eventually make its way into next generation SSK. The whole idea 2000 ton SSK carrying 8 Brahmos was beyond ridiculous it existed only as a model that was supposed to sucker IN into buying it.

The boat has resumed series production.The development of the AIP system was why it did not enter series prod. earlier.Read the Rubin bureau's notes on the same.

However the new Kalina class of which v.little is known will in the next decade possibly be the successor to the Kilo still being built becos of capability and v.low cost and building time just 2 yrs a sub.

Viv S · Post by **Viv S** » 21 Feb 2018 20:00

Three Lada-class submarines have been ordered to date (export variant: Amur). The first was rejected by the RuN and reduced to being a experimental vessel (Kilo-636s were ordered instead). The second and third boats have been delayed and the AIP plans deferred.

The Navy refused the newest submarines of the Lada project - Nov 2011

The Chief of Staff of the Navy told Izvestia on Wednesday that the testing program for the Lada project, which it was planned 10 years ago to begin updating the non-nuclear submarine forces, had to be rolled back.

- The combat composition of the fleet "St. Petersburg" will not be accepted. This is the final decision. The boat will remain an experimental specimen, on which individual complexes will be tested, "said a senior representative of the Navy's commander-in-chief.

The main drawback of "Lada" interlocutor of "Izvestia" called an unsuccessful engine, which was unable to develop more than half of the projected capacity.

In addition, the hydroacoustic complex of the boat is not ready for the development of which 1.3 billion rubles were spent, the information and control system "Lithium", torpedoes "TE-2 Toy."

- The project was beautiful, it did not work out. In fact, we have a full-scale mock-up of the ship. The boat is completely incapacitated for a number of important areas. Its defects and the rapid aging of the existing diesel submarines force us to return to the order of the verified "Varshavianok", - summed up the representative of the Navy.

According to him, the work on the other two boats of the Lada project - Kronstadt and Sevastopol, whose hulls are completely ready, is now frozen. Perhaps, they will be equipped with already tested engines from other projects, old systems and sold abroad.

In the "Admiralty Shipyards" expressed bewilderment at the rejection of the "Lada". According to the representative of the plant, hydroacoustics on the boat is already working, there are positive developments and with the engines.

"'Lada' has not yet exhausted its potential. With serious technological improvements and financing under the defence order, this project can still be saved. Such a decision will be in the interests not only of the Navy, but also of maintaining Russia's international image as a country capable of promoting its own high-tech products in the foreign market, "the representative of the Admiralty Shipyards explained.

Russia's Lada-class submarine project suffers further delays - Jan 2016

The completion of the second and third of Russia's troubled Lada-class submarines has been delayed again, while plans to equip the submarines with an AIP have been abandoned. Source: Rubin Design Bureau

The delivery of Russia's second and third Lada-class (Project 677) diesel-electric attack submarines will be delayed until 2019, according to Russian Navy and defence industry sources.

Admiralty Shipyard, which builds the submarines, has had its contract for the project changed as a result, the company's first deputy director general, Andrei Bystrov, stated.

A source in the Russian Navy Main Staff explained that the slowed construction of the second and third submarines was so that "due account [is] taken of the shortcomings revealed during the Northern Fleet's operation of the Project 677 lead ship, St Petersburg ". In addition, although the Russian Navy has planned for the class to be fitted with an air-independent propulsion plant (AIP), this will now not be the case as development of an AIP has been pushed back beyond 2020. "We have to wait until it [AIP] has passed its sea trials," the naval staff source said.

The construction of Project 677 submarines has been under way for almost 20 years; the lead ship, St Petersburg , was laid down in 1997 and has been in operational evaluation since its service entry in 2010. Kronstadt and Velikiy Luki were laid down in 2005 and 2006 respectively. Their construction was put on hold and then restarted only in 2013. In 2015 a defence industry source told IHS Jane's that the navy would receive these two Lada-class submarines in 2017 and 2018 respectively.

The Russian Navy is counting on receiving AIP power plants for submarines in 2021-2022, the head of the Russian Navy's shipbuilding department, Captain (1st Rank) Vladimir Tryapichnikov, said. "We presume that an AIP will be developed in the near future, and the Rubin Design Bureau has started such work recently. They have laid a good foundation … Rubin's designers keep on working hard [to develop the AIP], and we believe it will be developed in 2021-2022," he said.

So not even 1 P18 (or whatever comes after P15B) by 2027? That's too bad considering what cheen will deploy around 10 years from now.

Well we have the option of increasing the orders of the P-15B to 6 or 8 right now and start building them in more than one shipyard. But we don't seem to have the budget or the vision or perhaps both. There is shipbuilding capacity available if we look beyond the govt. yards. It will take a while to get going but once it does they can chip in for all further ship orders.

BTW that list doesn't include the Kamortas. They aren't counted as PSC's because of their ASW role?

From DRDO's newsletter, Mareech

DRDO newsletter

Anti-submarine warfare or ASW as it is popularly known is perhaps the most challenging and also the most fascinating form of warfare. NPOL, a constituted establishment of DRDO, occupies a unique space in oceans and ASW technology and had already developed a full platter of systems and technologies for ASW. APSOH, HUMSA, HUMSA NG and UG versions of hull mounted sonar, developed by NPOL, have been delivered to the Indian Navy (IN). Indian submarines navigate using NPOL designed submarine sonar suite USHUS and our ASW aircraft use dunking sonar and airborne processing systems. Maareech towed array sonar based Torpedo Defence System was designed and developed by NPOL to protect the ships of IN.

The survival capability of a ship is greater if the torpedo can be detected early and also at a range more than the the escape range of the platform. Hence, present day maritime warfare necessitates the requirement of reliable early warning torpedo detection and countermeasure systems that can directly engage the attacking torpedo. Maareech provides total defence against a torpedo attack. The main objective of the Maareech is to provide a reliable defence mechanism for all the surface ships of IN against torpedo attacks. Its core functions include automatic detection and alert of acoustic homing torpedoes (passive and active) and also acoustic decoying of the torpedo. Fully indigenous system comprises detection, classification and localization systems along with multiple types of countermeasure solutions. Naval Science and Technological Laboratory (NSTL), the other naval laboratory in the Naval Systems and Materials (NS&M) cluster of DRDO, has developed the expendable decoy countermeasure system, which is integrated with the Maareech system.

SYSTEM OVERVIEW

The detection system developed by NPOL comprises two sonar, namely, the Hull mounted sonar and towed array sonar for passive detection. Between them they provide panoramic detection and tracking of torpedoes. Apart from that there is an intercept sensor to characterize the active homing signature of the torpedo. Acoustic decoying is effected using two types of decoys namely the towed and expendable decoy. The decoys work in multiple modes depending on the situation. The complete wet end sensors including the towed array sonar is launched and retrieved using a hydraulically operated winch system. The onboard electronics processing system and HMI are combined in one single cabinet system which houses the front end electronics, signal processors and Display and control hardware. Industry standard Power PC’s and Multi SHARC FPP boards are used. The Maareech system incorporates advanced adaptive beam forming techniques for detection and tracking targets. The unique auto torpedo recognition algorithms clearly demarcate a torpedo target from non-torpedo target. Also intelligent soft kill decoy systems with multi-mode operational capability is built into towed and expendable decoy systems which helps to deter and decoy a possible attack on the mother ship. The expendable countermeasure system developed by NSTL consists of Fire Control System (FCS), Decoy Launcher (DL) and Expendable Decoy(ED). The sonar data after initial classification as a torpedo is being continuously fed to the FCS system. The target localization using Contact Motion analysis is being carried out by the FCS. Also important information regarding the target like torpedo speed, torpedo course etc. are also computed. FCS system also generates the escape recommendations including when to launch the expendable decoy, direction of launch, own platform course and speed etc. Fire Control System (FCS) interfaced with Maareech towed and hull mounted sonar, identifies high risk adversary and generates recommendations for the Commanding officer of the ship regarding the safest escape route. Also FCS computes the time instants and number of decoys to be deployed / fired. The decoys would be deployed with the command from ASW Officer through Decoy Launcher having multiple built -in safeties. Both towed and expendable decoys can work in multiple modes namely, broad band jammer, echo repeater and transponder modes.
....

Philip · Post by **Philip** » 24 Feb 2018 11:36

Mere decoys won't be enough."Smart" torpedoes make repeated attacks with v.long endurance ,at least a couple of hours,until the hit the target.A hard-kill option is necessary.

Some titbits.It appears (as usual) that BRF is ahead of the curve again.For a long time now we've been bemoaning the paucity of hardware aboard our OPVs and smaller warships.Not too long ago I wrote a piece about the need for smaller warships equipped with LR SSMs after the Ru demo in Syria using small corvettes to launch Kalibir SSMs at ranges of 2000+km! The same has now been ut forward to the MOD apparently by shipyards building our OPVs,etc., as it would increase cost only by around 10%.The OPVs built for Mauritius/SL,cost approx. just $60M,a steal in the international market.With a 200+ strong fleet planned by 2026,with little sign of that being achieved,equipping our smaller warships from 1000t to 2500t with BMos and other LR SSMs,would significantly enhance the capability of the In to conduct saturation attacks against enemy CBGs,etc.at long ranges too.

Incoidentally,the idea and need for maritime strike bombers is also being made louder.The IAF has been exceptionally myopic for decades. After the USSR collapsed,they had 300 Backfires available and the legacy KH missile used then ,was so accurate and devastating (16 ft. hole 40ft. deep),that it gave the USN the heebie-jeebies.Imagine,we (the IAF) were offered this aircraft in '71 after the BDesh war! If the IN had had the offer,they would've snapped it up immediately.The USN is now planning the tasking of their legacy B-52 and B-1 bombers with the new LR SSM.These bombers to last until 2040/50,will eventually have served for a century! Simply amazing,why the Russians also still use their Bears.These legacy bombers equipped with the new stand-off missiles,can strike enemy CBGs from rgeat distances and land attacks too.Imagine the IN being able to strike Chin ports and bases from far out of range of their aircraft and missile defences.The latest KH missile is supposed to climb to an alt. of 150,000 ft.before plunging to its target in a vertical dive at Mach 5! These bombers can also carry several numbers of missiles,at least 8-12 BMos variants unlike the MKI which can carry only one as of now,which would also take some significant amt. of time in restructuring the aircraft to do so.Operaing from the ANC theatre too,the In would have a significantly enhanced capability,able to strike deep and hard into the Indo-China Sea and the Pacific too,as well as anywhere in the IOR.

While the planners have now realised the dire necessity of having this capability in the aftermath of the Chinese mega naval expansion and aggressive maritime posture gobbling up the Spratlys first and now wanting to do just the same in the Maldives too, the MOD and political establishment should come around at the earliest in fast-tracking the innumerable pending decisions.

How difficult it is convert and OPV with Multiple launcher of Dhanush, Dhanush could be much cheaper to manufacture than Brahmos and if it has terminal guidance to take out ships, with multiple launchers could be pretty useful to us.

Philip · Post by **Philip** » 24 Feb 2018 12:38

Dhanush is a cumbersome missile that has to be launched from the vertical after being rolled out from the OPV's hangar.It is also costlier or at least equiv. than BMos ($2.75M) to my knowledge,as it is at least 500kg heavier.It can't be fired in seconds,has no canister capability,and was developed to give us some semblance of a naval N-strike capability a decade ago. The range of D'sh is said to be around 750km,but the new ER BMos is supposed to increase the range upto 900km. With the arrival of the Arihant class of SSBNs,the need for an N-tipped missile aboard our surface fleet diminishes,as once the K-5 missile is installed and on more Arihants,the need for an N-tipped missile aboard more vulnerable suurface ships decreases .The IN's req. being floated,for new SSMs non-silo launched,is indicative of either replacement of legacy SSMs on our FACs (M) and for installation aboard some of our other smaller vessels like the OPVs.Ideally,the BMos-NG,smaller in size would be perfect,or Klub,with its terminal M-3+ warhead.Kalibir is the ER version of the same.

srin · Post by **srin** » 24 Feb 2018 12:43

While agree that Dhanush is cumbersome, I think it is quite within our expertise to develop a solid-fuelled Prahaar-ER missile (say with strike range of 300 km) or even Iskander-class SSM. No problem with ramjet, no liquid propellants, no Russian "assistance" - none of that. We put in whatever seeker we want, and produce as many as we want.

It's much harder to design a AIP when you buying off the shelf designs with little to no TOT on design. Besides I highly doubt we might see P-75i inducted before 2035 so they have plenty of time.

Repeat the test in 7 days time or the next day as per the operation's tempo of a submarine to see if it works as designed.

So that the user has confidence in the AIP and then start fitting it to boats when they start coming up for midlife update.

DRDO AIP :- India Indigenously Developed Air Independent Propulsion System For Scorpene Submarine

DRDO developed PAFC powered AIP module technology already has been transferred to Thermax Ltd in Pune for further production even though first Scorpene submarines to get indigenous AIP System will happen only in 2021-22 when they come for their first refit after which all Six submarines will get AIP module.

Navy also plans to use DRDO developed AIP System for Six next generation Diesel-Electric submarines which will be procured under Project-75I (India) soon. DRDO also has given hints that it will also start work on next-generation AIP technology which can be incorporated in future Indian-built submarines under Project-76.
