DSRV

A DSRV, or Deep-Submergence Rescue Vehicle, is a specially designed submarine used to rescue crew members from larger sunken submarines. It’s built to operate at great depths, with advanced life-support and rescue capabilities. The DSRV can attach to the distressed submarine, seal the connection, and safely lift personnel to the surface. It is usually deployed in emergencies where crew members are trapped underwater, providing a critical safety measure for submarines operating in deep waters.
