Can you picture a ship that can stay hidden under water for months on end, manoeuvre sharply and speedily, and surface at just at the right time, literally out of the blue, to wreak havoc on the enemy?

That's a nuclear-powered attack submarine, or SSN, for you. Nuclear strategist Rear Admiral Raja Menon (retired) once called these submarines "the ultimate arbiter of sea power".

But what it is about these submarines that makes them so lethal? Dev Goswami and Shiv Aroor take a deep dive on this and much more on the latest episode of In Our Defence.

The Cabinet Committee on Security recently gave the go-ahead to develop and build two of these ‘sharks’ under a project that has been long pending.

On this episode, Dev and Shiv take a look at the super capabilities of nuclear-powered attack submarines, why the Indian Navy desperately needs them, and edge that the two now under-development sharks will give once they are in service.

Crucially, the two also discuss why the project to build these submarines was hanging fire for so long and delve on the opportunities that were lost as a result.

This is and more on this insightful new episode. Tune in!
