Mark 15 Torpedo
The Mark 15 torpedo, the standard American destroyer-launched torpedo of World War II, was very similar in design to the Mark 14 torpedo except that it was longer, heavier, and had greater range and a larger warhead. It was developed by the Naval Torpedo Station Newport concurrently with the Mark 14 and was first deployed in 1938. It replaced the Mark 8 torpedo on surface ships with tubes that could accommodate the longer Mark 15; this primarily included destroyers built after 1930. Older destroyers, primarily the ''Wickes'' and ''Clemson'' classes, continued to use the Mark 8, as did PT boats early in World War II. During the war 9,700 were produced at Newport and at the Naval Ordnance Station Forest Park, Illinois. The Mark 15 had the same basic design problems that plagued the Mark 14 for the first 20 months following U.S. entry into the war, though this was not realized nearly as quickly by the destroyer crews as it was by the submariners. One major shared defici ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supermarine Spitfire Variants Part Two
The British Supermarine Spitfire was facing several challenges by mid-1942. The debut of the formidable Focke-Wulf Fw 190 in late 1941 had caused problems for RAF fighter squadrons flying the latest Spitfire Mk Vb. Rolls-Royce engineers were already working on a new version of the Merlin incorporating a two-stage supercharger; the combination of the improved Merlin and the Spitfire Mk Vc airframe in a "stop-gap" design allowed the RAF to combat the Fw 190 on equal terms. In a second stream of development Supermarine was working on an improved, reinforced, Spitfire airframe which incorporated several new features and was designed for the Merlin 60 and 70 series engines. This new airframe later formed the basis for the Rolls-Royce Griffon powered Spitfires. This article presents a history of the Spitfire powered by two-stage engine variants and also describes some of the "drawing board" projects and experimental Spitfires. The Griffon powered variants are described in a separat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mark 15 Nuclear Bomb
The Mark 15 nuclear bomb, or Mk-15, was a 1950s American thermonuclear bomb, the first relatively lightweight () thermonuclear bomb created by the United States. A total of 1,200 Mark 15 bombs were produced from 1955 to 1957. There were three production variants: Mod 1, Mod 2, and Mod 3. The design was in service from 1955 to 1965. Specifications All three models were generally physically similar; weight of around , diameter of , length of . Models The Mod 1 corresponds to the Castle Nectar test of the Zombie weapon prototype. This test had a yield of . The Mod 2 corresponds to the Redwing Cherokee nuclear test of the TX-15-X1 test model, and had a yield of . Redwing Cherokee was the first US thermonuclear bomb airdrop test. a [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phalanx CIWS
The Phalanx CIWS (often spoken as "sea-wiz") is a gun-based close-in weapon system to defend military watercraft automatically against incoming threats such as aircraft, missiles, and small boats. It was designed and manufactured by the General Dynamics Corporation, Pomona Division,Thomas, Vincent C. ''The Almanac of Seapower 1987'' Navy League of the United States (1987) p.191 later a part of Raytheon. Consisting of a radar-guided Vulcan cannon mounted on a swiveling base, the Phalanx has been used by the United States Navy and the naval forces of 15 other countries. The US Navy deploys it on every class of surface combat ship, except the and . Other users include the British Royal Navy, the Royal Australian Navy, the Royal New Zealand Navy, the Royal Canadian Navy and the US Coast Guard (aboard its - and s). A land variant, the LPWS (Land Phalanx Weapon System), part of the C-RAM system, was developed. It was deployed to counter rocket, artillery and mortar attacks du ...

8-inch/55-caliber Gun
The 8"/55 caliber gun (spoken "eight-inch-fifty-five-caliber") formed the main battery of United States Navy heavy cruisers and two early aircraft carriers. United States naval gun terminology indicates the gun barrel had an internal diameter of 8 inches (203 mm), and the barrel was 55 calibers long (barrel length is 8 inch × 55 = 440 inches or 36.6 feet or 11 meters). Mark 9 These built-up guns weighed about 30 tons including a liner, tube, jacket, and five hoops. A down-swing Welin breech block was closed by compressed air from the gas ejector system. Loading with two silk bags each containing of smokeless powder gave a projectile a velocity of 2800 feet per second (853 m/s). Range was 18 miles at the maximum elevation of 41 degrees. Mark 12 These simplified built-up guns eliminated hoops to reduce weight to 17 tons. The breech mechanism was similar and loading two silk bags each containing 43 pounds (20 kg) of smokeless powder gave a 335-pound (152&nb ...

McMillan TAC-50
The McMillan TAC-50 is a long-range anti-materiel rifle. The TAC-50 is based on previous designs from the same company, which first appeared during the late 1980s. As of 2017 it holds the record for the longest confirmed sniper kill. McMillan makes several .50 caliber rifles, based on the same proprietary action, for military, law enforcement and civilian use. It is produced in Phoenix, Arizona, in the United States by McMillan Firearms Manufacturing. The TAC-50 is a military and law enforcement weapon, which, designated as the C15, has been the standard long-range sniper weapon (LRSW) of the Canadian Army since 2000. Rifles of the TAC-50 family are guaranteed to provide 0.5 minute of angle (MOA) groups with match-grade ammunition under ideal conditions. Design details The McMillan TAC-50 is a manually operated, rotary bolt-action rifle. The large bolt has dual front locking lugs, and its body has spiral flutes to reduce weight. The heavy match-grade barrel, made by Lilja barrels ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
