Russian Nuclear Submarine Force: Discussion

gather the max speeds given for the yasen-m are 35 knots +. It is very fast and the rumored depth is equally impressive. wrote:

A submerged speed of 35 knots is nothing new for SSN class vessels. Project 971 could already sail at this speed. As you know, the Russians have created submarines with even higher speeds. Papa and Alpha. Seawolf can also sail at such speeds as 35 knots. However, the 885M project can certainly dive much deeper than Western ships. Officially it is 600m, unofficially it is even deeper.

The most modern heavy torpedo Fizyk 2 compared to the latest versions MK-48 or Spearfish. How does it compare? Available information shows that it has a range of about 50 km and a speed of 50-60 knots. It descends below 500m. MK-48 has similar performance down to 800m. In the case of Russian torpedoes, this is not necessary. American ships don't go below 500m

Typical Yankee nonsense. Torpedoes using Otto fuel *all* have degraded performance at high depth. Mk-48 included. For this reason the Europeans typically use electric torpedoes. Which do not have the same performance degradation while operating at high depth. wrote:

This is interesting because the MK 48 ADCAP was a response to the Proj 705 Lira ships. The torpedo was designed for a depth of up to 800 m. Generally speaking, most heavy torpedoes are powered by Otto fuel. Fizyk 2 also descends to over 500m. It is the most modern Russian heavy torpedo.

Interesting project.  It seems that Europe has overtaken the USA and Russia in this respect by creating heavy electric torpedoes.  Russia The US still uses chemical drives in its heaviest torpedoes? Since the electric drive is certainly quieter, safer, and works better at greater depths.

Russia's 5th-Gen Submarines to Get 20% Thinner Coating, 07.08.2024.

MOSCOW (Sputnik) - Russia's fifth-generation submarines will receive new hydroacoustic rubber coating that will be 20% thinner and much more efficient, Valery Polovinkin, science principal at the Krylov State Research Center (KSRC), told Sputnik on Monday.

"We are talking about thickness reduction of about 10-20%, which is quite significant. It's not just the formulation of substances — special channels are made in the coating. It is not just a monolith but a construction, because air is the best insulator," he said.

Polovinkin added that submarines needed better camouflage coating because no armor could beat armor-piercing projectiles.

"Unfortunately, the projectile wins the notorious battle of 'the shell hit versus the armor.' We need to hide the ships," Polovinkin explained.

Scientists at the KSRC, the main developer of the latest ship and material designs for the Russian navy, are working on polyfunctional coatings for fifth-generation submarines, the scientist said.
