Why Soviet service differed between transferred British ships

Why did the transferred battleship Royal Sovereign return in poor condition when a transferred cruiser did not?

The Soviet Union lacked the facilities to maintain the battleship properly, while it did have the support needed to keep the cruiser in better condition.

The poor condition of the former Royal Sovereign contrasts with a transferred cruiser that returned in good shape. The difference was not simply Soviet willingness but whether the available maintenance and industrial facilities matched the ship. A fleet can receive a hull without inheriting the dockyard capacity, spares, and specialist knowledge needed to sustain it. The comparison is a compact case study in why operating an inherited capital ship is harder than merely taking possession of one.
