SLQ-25 Nixie aboard USS Iowa TB-14A towed decoy, from the AN/SLQ-25A/C "Nixie" system. The AN/SLQ-25 Nixie and its variants are towed torpedo decoys used on US and allied warships. It consists of a towed decoy device (TB-14A) and a shipboard signal generator. The Nixie is capable of defeating wake-homing, acoustic-homing, and wire-guided ...
In order to recover a floating torpedo it is first necessary to find it. Prior to the advent of electric torpedoes, which first reached the U.S. fleet in September 1943, [4] torpedo recovery boats could follow the stream of bubbles generated by the weapon's propulsion system. Also aiding the retrievers was that early torpedoes were primarily ...
The Test were done by the first two Motor Torpedo Boat Squadrons one and two. [3] [4] With the new boats a new base was built, to train the new Squadrons at Melville, Rhode Island on Narragansett Bay, the Melville Motor Torpedo Boat Squadrons Training Center. [5] Motor Torpedo Boat Squadron 4 was based at the Training Center to train the new ...
A motor torpedo boat is a fast torpedo boat, especially of the mid 20th century. The motor in the designation originally referred to their use of petrol engines, typically marinised aircraft engines or their derivatives, which distinguished them from other naval craft of the era, including other torpedo boats, that used steam turbines or ...

The Mark 14 torpedo was the United States Navy's standard submarine-launched anti-ship torpedo of World War II. This weapon was plagued with many problems which crippled its performance early in the war.
The equations implemented in the angle solver can be found in the Torpedo Data Computer manual. [40] The Submarine Torpedo Fire Control Manual [41] discusses the calculations in a general sense and a greatly abbreviated form of that discussion is presented here. The general torpedo fire control problem is illustrated in Figure 2.
USS Jamestown (PG-55) was a patrol gunboat and after 13 January 1943 a Jamestown-class motor torpedo boat tender acquired by the U.S. Navy during World War II.Her task in her final classification was to provide a "home base" for torpedo boats in remote parts of the ocean during the war, and to provide them with necessary services, such as fuel, food, and repairs.
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.
