Project-76 Indigenous Diesel-electric Submarine (SSK) Program

We must remember that P-75I is to be a new 3000t+ design with a brand new AIP from TKMS and external hull shaping similar to Type 212C/D. In terms of dev risk, I'd say this is almost on par with the S-80 which was rejected.

That apart, I'm hoping L&T was able to glean some of the S-80s engineering and design secrets during their brief collab with Navantia. Jayant Patil seemed really confident their P-76 design would be ready in 1 years time.

Of p75i sub.

Looks a stealthified + enlarged version of type214(sailed remains similar in size).


For better look at current type214 sub, here's the korean derivate


Though don't know why they didn't offer type 212cd, which already has similar submerged displacement.

This actually looks like Type 216, including the X-rudder. Only difference is the hull is now faceted, probably based on work done for Type 212CD.

TKMS apparently proposed this for the Australian SSK requirement which was eventually won by NG Barracuda before it got AUKUS'd.

Afaik, 212 is export restricted as it has advanced tech like non-magnetic hull.

Well 216 is a larger and modified version of 214, so this checks out.

They lost half their country to communists. Do not defend the un-defensible.

They were not supported anymore than we were.

Study the rise of Samsung in South Korea.

They struggled more than India in 50s.

But they realised as a nation what was important. Education for its population and industrialisation at all costs.

Korea literally had US nuclear shield protecting them and US troops defending their borders from a stronger adversary. India had to build its own military and nuclear capabilities which brought world sanctions, contempt and hence delayed economic progress.

They also had a benevolent dictator who built up many of their capabilities, Park Chung He. If India ever had a dictator, either that dictator would die like a dog as Indira did or India would split into 100 different pieces.

You cannot skip steps and cannot defeat basic economics.

1. You let a submarine line go idle, you have to pay the fixed costs all over again in addition to the time lost.

2. You start developing the replacement when you are doing the MLU for the system.

Kilo class sub was a true nice design, something like F16 at its time, but now it is obsolete.
Better to copy Scorpene....

Ideal case would have been to ensure the Scorpene line continued for another 6 units, while India worked with France to have something like Orka, and build 12 units for that, and by the time 6th Orka was in water, India should have aimed to have its own prototype in the water.
