It was to feature an open architecture, allowing it to serve as a host to other systems and support their information gathering and threat detection. [7] In 2012, the AN/SLQ-25D program became a part of the Surface Ship Torpedo Defense (SSTD) program, a US Navy effort to field a system that could detect and destroy incoming torpedoes.
Torpedo boats, such as MTBs, PT boats, or S-boats, enabled the relatively small but fast craft to carry enough firepower, in theory, to destroy a larger ship, though this rarely occurred in practice. The largest warship sunk by torpedoes from small craft in World War II was the British cruiser Manchester , sunk by Italian MAS boats on the night ...
The guidance system used four hydrophones on the torpedo's midsection, connected to a vacuum tube-based sound processing array. A Bell proportional navigation and HUSL non-proportional steering system were demonstrated by July 1942. The body was a modification of the Mark 13 torpedo. Length, diameter, and weight were reduced.
PT-105, an 80' Elco boat, under way. A PT boat (short for patrol torpedo boat) was a motor torpedo boat used by the United States Navy in World War II.It was small, fast, and inexpensive to build, valued for its maneuverability and speed but hampered at the beginning of the war by ineffective torpedoes, limited armament, and comparatively fragile construction that limited some of the variants ...
Wake behind a vessel of the German navy Soviet 53-65K torpedo developed during the Cold War. Wake homing is a torpedo guidance technique based on the wake trajectory left behind a moving target. [1] The torpedo is fired to cross behind the stern of the target ship, through the wake.
Torpedo defence includes evasive maneuvers, passive defense like torpedo belts, torpedo nets, torpedo bulges, and sonar torpedo sensors, "soft-kill" active countermeasures like sonar decoys and sonar jammers, and "hard-kill" active defenses, like anti-torpedo torpedoes similar in idea to missile defense systems.

Primary weapon for the Type 039 is the 533 mm Yu-4 torpedo, a locally produced passive homing 40-knot (74 km/h) torpedo based on the SAET-50 and roughly comparable to the SAET-60. Surface targets may be attacked at up to 15 km. Yu-6 wire-guided torpedoes may also be used for targeting submarines.
The Motosilurante CRDA 60 t (also known as MS boat) was a type of motor torpedo boat built for the Regia Marina during World War II.It was designed on the pattern of German S-boats — some early examples of which were captured by the Italians from Yugoslav Navy — to complement the faster but less seaworthy MAS boats.
