G7e Torpedo
The G7e torpedo was the standard electric torpedo used by the German ''Kriegsmarine'' submarines in World War II. It came in 20 different versions, with the initial model G7e(TII) in service at the outbreak of the war. Due to several problems, leading to the German "''Torpedokrise''" which lasted until the end of 1941, the improved G7e(TIII) took over as the standard electric torpedo used by German U-boats for the rest of the war. G7e torpedoes measured in diameter and about in length. Depending on the type, the warhead contained a main charge of of '' Schießwolle 36'', a mixture of dipicrylamine and TNT. All were powered by electric motors and lead-acid batteries which required onboard maintenance to maintain their functionality. Other major G7e-versions that saw operational service during the war, were the first acoustic homing torpedo G7es(TIV) ''Falke'' and its improved successor G7es(TV) ''Zaunkönig''. G7e(TII) The G7e(TII) went in service with German U-boat fleets ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Japanese 53 Cm Torpedo
Numerous 53 cm (21-inch, 533 mm) torpedoes have been used by the Imperial Japanese Navy and its successor, the Japan Maritime Self-Defense Force, since their first development just before the First World War. Torpedoes of 21-inch caliber are the primary size category used worldwide. In Japan, they are used by surface ships and submarines, and comprise the predominant majority of submarine torpedoes; historically, aircraft and midget submarines used smaller Japanese 45 cm torpedo, 45 cm torpedoes, and surface ships additionally used Japanese 61 cm torpedo, 61 cm torpedoes. Japan also employs Japanese 32 cm torpedo, 32 cm torpedoes which conform to the NATO 12.75-inch (323.8 mm) standard; these are dedicated Anti-submarine warfare, ASW weapons, often delivered via aircraft. The 12.75 inch standard for light ASW torpedoes was originally defined by the dimensions of the Mark 46 torpedo. Prior to 6 October 1917, Imperial units, imperial measurements were used.

Mark 18 Torpedo
The Mark 18 torpedo was an electric torpedo used by the United States Navy during World War II. The Mark 18 was the first Battery (electricity), electric storage battery torpedo manufactured for the US Navy and it was designed primarily for use as a submarine-launched torpedo. Development The Mark 18 was built in competition with the Bureau of Ordnance electric torpedoes, which had been in development at the Naval Torpedo Station (NTS), Newport, Rhode Island, Newport, Rhode Island, since the 1920s,, p. 280 in particular the Mark 20 torpedo, Mark 20, originated in 1941 in collaboration with General Electric and Exide, Electric Storage Battery Company. In 1942, several German G7e electric torpedoes ran ashore, leading Chief of Naval Operations, CNO, Admiral Ernest J. King, to urge BuOrd to build an electric torpedo for the U.S. Navy's own submarines. BuOrd told NTS to get the Mark 20 in shape, or drop it in favor of a copy, with the primary emphasis being speed of introduct ...

British 21-inch Torpedo
There have been a number of 21-inch (53.3cm) torpedoes in service with the Royal Navy of the United Kingdom. Torpedoes of 21-inch calibre were the largest torpedoes in common use in the RN. They were used by surface ships and submarines; aircraft used smaller 18-inch torpedoes. Mark I The first British 21-inch torpedo came in two lengths, "Short" at , and "Long" at . The explosive charge was of guncotton, increased later to . The torpedoes were first deployed in the field in 1912 and primarily used by the s throughout most of their service during the First World War.

VP-84
VPB-84 was a Patrol Bombing Squadron of the U.S. Navy. The squadron was established as Patrol Squadron 84 (VP-84) on 1 October 1941, redesignated as Patrol Bombing Squadron 84 (VPB-84) on 1 October 1944 and disestablished on 28 June 1945. The squadron flew the PBY-5A Catalina throughout its operational history. Operational history *1 October 1941 – 15 April 1942: VP-84 was established at NAS Norfolk, Virginia, under the operational control of PatWing-8. The squadron remained without aircraft during training. In December the squadron was transferred to NAS San Diego, California, for a month of ground and flight training. On 1 February 1942, it was transferred to NAS Alameda, California, for advanced flight training in the PBY-5A Catalina. The squadron then returned to NAS Norfolk in two detachments, departing the West Coast on 12 and 15 April 1942.

PBY Catalina
The Consolidated Model 28, more commonly known as the PBY Catalina (U.S. Navy designation), is a flying boat and amphibious aircraft designed by Consolidated Aircraft in the 1930s and 1940s. In U.S. Army service, it was designated as the OA-10 and in Canadian service as the Canso, and it later received the NATO reporting name Mop. It was one of the most widely used seaplanes of World War II. Catalinas served with every branch of the United States Armed Forces and in the air forces and navies of many other nations. The last military PBYs served until the 1980s. As of 2021, 86 years after its first flight, the aircraft continues to fly as a waterbomber (or airtanker) in aerial firefighting operations in some parts of the world. Design and development Background The PBY was originally designed to be a patrol bomber, an aircraft with a long operational range intended to locate and attack enemy transport ships at sea to disrupt enemy supply lines.

Mark 24 Mine
The Mark 24 mine (also known as FIDO or Fido) is an air-dropped anti-submarine (ASW) acoustic torpedo developed by the United States during World War II; it was called a mine to conceal its capabilities. The torpedo entered service with the Allies in March 1943; the United States Navy (USN) used it until 1948. Approximately 4,000 were produced. Of the 340 deployed during the war, 204 were fired, sinking 37 and damaging 18 Axis submarines. Background The concept of the acoustic torpedo existed by World War I, but was impractical due to the insufficient understanding of underwater acoustics. Germany was developing electrically-driven acoustic torpedoes by 1933; the resulting G7e and G7es anti-ship torpedoes, running at a preset depth, entered service on submarines in 1943. The USN received a similar anti-ship torpedo, the Mark 28, in 1944. ASW torpedoes must detect and respond to greater changes in depth and azimuth than anti-ship torpedoes. FIDO was designed within the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNAT (torpedo)
GNAT is a free-software compiler for the Ada programming language which forms part of the GNU Compiler Collection (GCC). It supports all versions of the language, i.e. Ada 2012, Ada 2005, Ada 95 and Ada 83. Originally its name was an acronym that stood for ''GNU NYU Ada Translator'', but that name no longer applies. The front-end and run-time are written in Ada. History The GNAT project started in 1992 when the United States Air Force awarded New York University (NYU) a contract to build a free compiler for Ada to help with the Ada 9X standardization process. The 3-million-dollar contract required the use of the GNU GPL for all development, and assigned the copyright to the Free Software Foundation. The first official validation of GNAT occurred in 1995. In 1994 and 1996, the original authors of GNAT founded two sister companies, Ada Core Technologies in New York City and ACT-Europe (later AdaCore SAS) in Paris, to provide continuing development a ...
