LR7
The LR7 is a manned submersible undersea rescue vehicle in service with the People's Liberation Army Navy since 2009, and is usually deployed onboard one of China's Type 926 submarine support ships. Constructed by the British firm Perry Slingsby Systems, of the Triton Group, as a development of earlier LR5, the 25 ft long LR7 is designed for retrieving sailors from stranded submarines at a depth greater than 300 meters, and is capable of rescuing 18 at a time.
