usn_mk37eTorpedoUSA
The Mark 37E torpedo is an upgraded version of the Mk-37C torpedo with wake-homing capability and a redesigned seeker. Exclusively used by export partners, the Mk-37E (NT-37E) has upgraded anti-ship capabilities and minor refinements to propulsion allowing for a very competent anti-submarine and anti-ship torpedo for the mid 1980s.
