Israeli Mark 37E torpedo. The mod 1 torpedoes were longer, slower and heavier than mod 0, but offered better target acquisition capabilities and higher ability to intercept agile submarines. They used wire-guidance. The efficiency of Mk37 torpedoes was high for targets with speed lower than 20 knots (37 km/h) and depth less than 1,000 ft (300 m).
