Russia has been talking about this submarine and the
Poseidon drone for years (2018)

The ‘Poseidon’ nuclear-powered torpedo is designed to bypass such existing defences. It is intended to travel quietly — and quickly — through the world’s oceans and cross intercontinental distances. Once near a key target, its nuclear warhead will detonate.
The resulting shockwave and vaporised body of water is expected to generate an unstoppable tsunami.
“(The) unique characteristics of the Poseidon system will help the navy to successfully combat aircraft carriers and strike groups of a potential adversary in any oceanic theatre of war and destroy shore infrastructure facilities,” Admiral Igor Katasonov has told Russian media.
