Research on observability of two wire-guided torpedoes tracking system [PDF]
Under special condition, the surface target could be attacked by the submarine with two wire-guided torpedoes with passive acoustic homing mode. When the acoustic homing device detects the target bearing and transmit it back to the submarine through the ...
