SUBSEA DEFENSE

CURV-21 is a 6,400-pound Remotely Operated Vehicle (ROV) that is designed to meet the US Navy’s deep ocean salvage requirements down to a maximum depth of 20,000 feet of seawater. This vehicle is loaded with a host of new technologies and was built as a direct replacement for CURV-III but with a smaller overall system footprint.
