Russia's only Kilo Pump Jet class Submarine Is Back In Action#shots

Yes, that's correct. The Russian submarine B-871 Alrosa, the only pump-jet Kilo-class submarine in the world, has returned to active service after a major upgrade. The submarine was refitted with a new sonar system, a new combat management system, and a new weapons suite, including Kalibr cruise missiles. The Alrosa is now back in the Black Sea Fleet and is reportedly being deployed to support Russian operations in Ukraine.

The Alrosa is a unique submarine in several ways. It is the only pump-jet Kilo-class submarine, which gives it a lower acoustic signature than traditional propeller-driven Kilos. It is also the oldest submarine in the Black Sea Fleet, having been commissioned in 1990. However, the Alrosa has been kept in good condition and is still considered to be a capable submarine.

The return of the Alrosa to active service is a significant development. It means that the Russian Black Sea Fleet now has a more capable submarine force to support its operations in Ukraine. The Alrosa's new weapons suite also gives it the ability to strike targets at longer ranges, which could make it a more effective threat to Ukrainian forces.

The Alrosa's return to active service is also a reminder of the importance of submarines in modern warfare. Submarines are difficult to detect and can strike targets with impunity. They are therefore a valuable asset for any navy, and the Alrosa's return to service shows that Russia is still committed to maintaining a strong submarine force.
