Larsen and Toubro (L&T) and Indian Navy's Warship Design Bureau are at an advanced stage of completing design of 2,500 tons conventional diesel electric submarines to be completed under one year. L&T was selected as a joint design partner after a competition.

VIDEO: https://x.com/DefenceDecode/status/1946817232534737284 ---> In a major development, J.D. Patil, Director and SEVP of L&T Defence, revealed an accelerated conventional submarine design program — informally named 'Project-76' — being pursued in partnership with the Warship Design Bureau. Its design is on advance stages and will reach finalization in just one year.

Very good steps. They delivered on their commitments unlike PSU fellows

What gives ? No foreign collaboration ? How did L&T acquire the required expertise ?!!

I hope it materializes then we might have 3 shipyard for submarine building.

HSL & MDL to build SSN/SSGN/SSBN

L&T to build SSK.

This will help to build up the sizeable sub surface capability in a relatively quick time.

MDL is also building the three follow on Scorpenes + the six Project 75I vessels.

Hoping that the six build Project 76 SSK program transitions to *AT MINIMUM* a 12 build program.

knowing INs propensity for 3s and 6s , it could be a variant or a different class after 6 !

[Rakesh]

Indeed. So true. Well said.

[nash]

When we can have our own P-76 SSK, then there should not be any P-75I. All the stakeholders should focus on this P-76 program and production run of 12-18 submarines in 3 or 4 tranches.

If there is any thoughts of stopgap, then it should be SSN and here MDL production line could be used after the 3 Scorpenes.

In the Video its said to be a 1500 ton Submarine and not the 3000 ton reported earlier. Assuming it to be Scorpene design+ATV Systems to keep it indigenous. Add to that DRDO AIP. If this is true, then the project will fructify much more faster.
