the sstd ( surface ship torpedo defense) system is a defensive system under development to counter specific undersea weapons threats to high value surface ships. The system consists of detection, control, and counter weapons subsystems. The counter weapon portion is comprised of a hardkill subsystem for outer layer engagment and a seduction subsystem for inner layer defense. SSTD is the first undersea warfare program to use a layered-attrition approach for the defense of surface ships.
