The Kursk was an Oscar II class submarine, of the Russian Navy.
The Kursk was a large, modern Russian nuclear submarine that was lost in the Barents Sea on August 12, 2000. She went down with all hands. Russia mourned the loss of the boat and her crew, and questions arose as to the reasons for a delay in response to reports she had gone down. As an aside, it is almost a certainty that submarine sailors around the world shared the grief at Kursk's sinking. A brief history of K-141, the Kursk, can be found by using the link provided to our friends at Wikipedia.
because theyre rescue vessels were in poor condition and the rescue subs were badly crewed

Most modern submarines have one screw (which is the proper term for a propeller). Some of the really big ones have a pair of them, like the Russian submarine Kursk, for example. But the bulk of the designs incorporate a single screw.
The submarine will float when its weight is equal to the upthrust acting on it. This is because the upthrust force pushing the submarine upwards is equal to the weight of the water displaced by the submarine, resulting in a state of equilibrium where the submarine neither sinks nor floats.
The Russian Navy's Oscar II-class (NATO reporting name) submarine K-141 Kursk sank as a result of an initial torpedo fuel detonation, and secondary torpedo warhead explosions (5-7), on August 12, 2000. Though 23 crew were known to have survived in the stern, they eventually perished along with the rest of the crew.
The K-141 Kursk was a Russian nuclear cruise missile submarine. It was lost with all of its men on board when it sank in the Barents Sea on August 12, 2000. That day, the Kursk sailed out to sea to fire dummy torpedoes. The missiles were fired, and an explosion occurred soon after. It is speculated that this was due to the failure and explosion of one of Kurskâ??s new/developmental torpedoes.

Kursk is the capital city of Kursk Oblast. Kursk is both a city and a region in western Russia, bordering Ukraine.
As the battle was called battle of Kursk, it was fought in Kursk, USSR. So the city which was liberated by the soviets was Kursk.
A submarine actually controls its weight by allowing water to enter or exit hollow chambers in its hull. These chambers are called ballast tanks. Ballast is anything carried in a ship to give stability. When water is allowed to flood into a submarine's ballast tanks, the weight of the submarine increases. When this increased weight exceeds the submarine's buoyancy, the submarine will sink. To allow the submarine to rise, air is pumped into the ballast tanks. The air forces out the water, reducing the weight of the submarine. The submarine then becomes lighter, buoyancy increases, and it floats to the surface. A submarine can also be made to "float" underwater at any depth by adjusting the amount of water weight in its ballast tanks.
