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.
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.
The Mark 48 was initially developed as REsearch TORpedo Concept II (RETORC II), one of several weapons recommended for implementation by Project Nobska, a 1956 summer study on submarine warfare. [9] The Mk-48 torpedo was designed at the end of the 1960s to keep up with the advances in Soviet submarine technology.
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 ...
Once the system was "locked" on the target, it produced a continuous fire control solution. While these fire control systems greatly improved the long-range accuracy of ship-to-ship and ship-to-shore gunfire, especially on heavy cruisers and battleships, it was in the anti-aircraft warfare mode that the Mark 1 made the greatest contribution.
A Mark 46 Mod 5A torpedo is inspected aboard a destroyer in April 2005. Contra-rotating propellers have benefits when providing thrust in marine applications. Contra-rotating propellers are used on torpedoes due to the natural torque compensation and are also used in some motor boats.
It shares much of the software and computer hardware of the Mk 48 ADCAP heavy torpedo, based around a custom PowerPC 603e microprocessor. Developmental testing began in July 1999, and a successful critical design review was completed in November 1999. In April 2003, Raytheon was awarded a sole source contract for the production of the Mk 54.
The Mark 46 torpedo is the backbone of the United States Navy's lightweight anti-submarine warfare torpedo inventory and is the NATO standard. These aerial torpedoes are designed to attack high-performance submarines. In 1989, an improvement program for the Mod 5 to the Mod 5A and Mod 5A(S) increased its shallow-water performance.
