China has developed a new type of escape system for individual submarine crew members and successfully completed a combat testing for the system, as the country reaches world-level in related technologies, according to recent media reports.

During the test, six submarine crew members wearing the new escape systems quickly surfaced from a submarine that dived to the seabed of the East China Sea and safely reached the surface, China Central Television (CCTV) reported last week.

The test validated the system's parameters including basic functions, compatibility, reliability and safety, Gu Jinghua, chief designer of the system, said in the CCTV report.

Developed by the Naval Medical University of the People's Liberation Army (PLA), the system consists of a buoyant escape suit, an air inflation helmet and self-examine devices for the suit and the helmet, CCTV reported.

In the event of a submarine accident, crew members could use escape capsules on the submarine together with the new escape suit and safely reach the surface from a depth of 200 meters, or use breathing apparatus along with the new decompression escape method from a depth of 120 meters, CCTV said.

The new system is compatible with all types of submarines in service with the PLA Navy, the report said.
