This was retrofitted into older boats, beginning with Dolphin and up through the newest Salmons. [20] The first submarine designed to use the TDC was Tambor, [21] launched in 1940 with the Mark III, located in the conning tower. [20] (This differed from earlier outfits.) [22] It proved to be the best torpedo fire control system of World War II ...
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.
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.
On November 8, 1940, Motor Torpedo Boat Squadron Two duty was to test new PT boats after the PT Boat design competition. [4] A Plywood Derby was held to see which PT boat design was the best. Motor Torpedo Boat Squadron Two did testing in March 1941 in a boat run from Key West to New York. During the trip there was heavy weather with 8-to-10 ...
It was Kriegsmarine's first operational torpedo (hence "TI" = Torpedo number one), and the standard issue torpedo for all German U-boats and surface torpedo-bearing vessels from 1934 to the end of WW2. The GA VIII gyroscope, as used in the G7a(TI) torpedo. The torpedo was a straight-running unguided design, controlled by a gyroscope. The TI had ...
Vedetta anti sommergibile (anti-submarine picket boat), commonly abbreviated as VAS and also known in Italy as VAS Baglietto (from the name of the shipyard that designed VAS and built a number of them), was a class of motor torpedo boats that served as coastal anti-submarine patrol boats in the Regia Marina (Italian Royal Navy) during World War II.
PT-109 is a torpedo-boat simulation game which starts in the practice-tactics mode to teach new players how to operate the boat, fire torpedoes, read radar on different displays, using the engine muffler to approach quietly, operating smoke screens, and locate other weaponry. Players also learn about the history of the ship, because some of the ...
The system is difficult to jam, but it can be distracted by other ships crossing the wake. In 2013, the US Navy tested prototypes of a system known as the Countermeasure Anti-Torpedo (CAT), [2] which had been designed to intercept and destroy the incoming torpedo. Deployment of the system did not proceed as planned due to performance issues. [3]
