So by now we have inducted and operationalized two scorpeans... INS Kalveri and INS Khanderi.... two scorpeans INS Karanj and INS Vela under sea trials.... can someone inform when these two are likely to be commissioned?

What is the status of other two INS Vaghir and INS Vaghshir? Correct me if names of remaining scorpeans are wrong

French, German firms in final race to supply torpedoes for Navy’s nuclear, Scorpene submarines




German Atlas Elektronik and French Naval Group are in the final race for supplying heavyweight torpedoes for the Indian Navy’s tender to acquire around 100 of them for the Scorpene class conventional and Arihant class nuclear submarines.

“The last day for responding to the tenders was January 17 last week and only two firms including German Atlas Elektronik and French Naval Group have responded to the request for proposal issues in this regard,” defence sources told ANI here.

The tender assumes significance as the French-origin Scorpene submarines, being built in India at the Mazagon Dockyards Limited (MDL), have not yet been equipped with new torpedoes.

The Scorpene-class boats have now been named the Kalvari class. The first boat of the class called INS Kalvari has already been inducted into the Navy and is carrying out operational duties.

As per the details of the project, the immediate requirement of the Navy for heavyweight torpedoes would be met by the acquisition to be made through the foreign vendors, while the long-term bulk requirement would be fulfilled through the ‘Made in India’ route.

The Navy has also taken assurances from global suppliers that their torpedoes would be allowed by their respective governments for being deployed on the Arihant class nuclear powered ballistic submarines.

Varunastra is ship launched toroedo.. for use in subs they might have to modify design.. not sure if any such project is underway.
Underway but not to be in service soon enough.
The Varunastra Torpedo has been selected for service on board the Sindhughosh Class aka Kilo Class submarines of the Indian Navy.

Indian Navy will soon get the first batch of indigenously-built heavyweight anti-submarine torpedo Varunastra, giving it crucial firepower to the naval forces.

The first batch will be delivered to the Navy soon and will be fitted onto Sindhu class submarines and other navy ships.

Navy to get third Scorpene submarine in December


The third Scorpene submarine, Karanj, will be delivered to the Indian Navy by December and all six submarine deliveries would be completed by 2022, Nicolas de La Villemarque, Vice President India, Asia and Pacific of Naval Group, said on Wednesday.

Mr. Villemarque said discussions were on to fit Air Independent Propulsion (AIP) modules on all Scorpenes beginning 2023. “The Scorpene submarine has the ability to be equipped with an AIP system. The first AIP will be equipped during the first refit of the first Scorpene,” he said in a conversation with The Hindu at Defexpo 2020, which began here on Wednesday.


Talks were underway with the Defence Research and Development Organisation (DRDO), Mazagon Dock Shipbuilders Limited (MDL) and the Navy. A design agreement was expected to be signed with the DRDO by the year end, he stated.

Karanj was launched into water in January 2018 and is currently in advanced stages of sea trials. The first Scorpene, Kulvari, was commissioned in 2018 and it would go for a normal refit after six years in 2023, during which time time the AIP would be installed. Second Scorpene Khanderi was inducted in September last.

An indigenous fuel cell-based AIP module is currently under development by the DRDO. The project reached a milestone in October 2019 with the successful operation of a land-based prototype engineered to the form-and-fit of a submarine. The DRDO has expressed confidence that the module will be ready in time for installation on Kulvari.

An AIP module gives stealth and extended endurance to diesel-electric submarines by allowing them to stay submerged longer.

Mr. Villemarque said they would do design simulations to “work out the technicalities of the project which involves Jumboisation, the process of cutting, joining and putting various blocks together.”

Project-75I
Naval Group is among the five Original Equipment Manufactures (OEM) shortlisted for the Navy’s project for advanced submarines under Project-75I being processed through the Strategic Partnership (SP) model of defence procurement. MDL and Larsen & Tourbo are the two Indian companies shortlisted under it and the Request For Proposal (RFP) would be issued to them.

Mr. Villemarque said they awaited a interest from the Indian companies to discuss potential tie-ups. “Our submarine is bespoked to the Indian Navy requirements. It was based in both Scorpene and Barracudda class platforms,” he added.

The Naval Group last month responded to the Navy’s long-pending tender for heavy weight torpedoes, which would equip the Scorpenes.

Delayed plan
Earlier, the Navy planned to install AIP modules on the last two of the six Scorpenes as they rolled out of the production line. However, it could not be realised due to developmental delays.

MDL is manufacturing the submarines with technology assistance from the Naval Group under a $3.75 bn deal signed in October 2005.

The first AIP will be equipped during the first refit of the first Scorpene,” => seems that is now a reality.



Project-75I
“Our submarine is bespoked to the Indian Navy requirements. It was based in both Scorpene and Barracudda class platforms,” => Probably a higher diameter hull Scorpene like sub so as to fit VLS... Probably a little bit heavier. A intermediate between Scorpene and Heavy Barracuda short fins.

Is the indian product mature enough? Has India the know-how to study and produce with very few experiences such a high tech weapon? Probably not yet. This is why you ordered a small batch of these european world top products, while probably ordering some indigenous products for less valuable targets.

We have quite good experience in developing torpedos it's not our first attempt we have developed many of them before but all of them are surface launched that's why we went for import of sub launched in small numbers so by that time our own indegeneous heavy Weight torpedo is ready.

Varunastra is too big to fit in the Scorpene torpedo launch tubes. But, Varunastra can be launched from our Kilo class fleet.
