The Mark 7 was a variable-yield fission weapon that used a levitated pit and an implosion design with 92 high-explosive lenses. The weapon had multiple yields of 8, 19, 22, 30, 31, and 61 kt by using various weapon pits. [4] The weapon had airburst and contact fuzing modes. The weapon used in flight insertion for safing and later versions of ...
The lightweight 16-in/50 Mark 7 was designed to resolve this conflict. These guns were 50 calibers long, 50 times their 16-inch (406 mm) bore diameter with barrels 66.7 ft (20.3 m) long, from chamber to muzzle. Each gun weighed about 239,000 lb (108 t) without the breech, and 267,900 lb (121.5 t) with the breech. [1]
W49. The W49 was an American thermonuclear warhead, used on the Thor, Atlas, Jupiter, and Titan I ballistic missile systems. W49 warheads were manufactured starting in 1958 and were in service until 1965, with a few warheads being retained until 1975. The weapon itself was a Mark 28 Y1 warhead modified for the missile role.
2,820 kilometres (1,750 mi) Flight altitude. 630 kilometres (390 mi). The PGM-17A Thor was the first operative ballistic missile of the United States Air Force (USAF). It was named after the Norse god of thunder. It was deployed in the United Kingdom between 1959 and September 1963 as an intermediate-range ballistic missile (IRBM) with ...
ASROC 'Matchbox' reload doors are visible in this photograph of the Japanese Asagiri -class destroyer, in 2008. The RUR-5 ASROC (for "Anti-Submarine Rocket") is an all-weather, all sea-conditions anti-submarine missile system. Developed by the United States Navy in the 1950s, it was deployed in the 1960s, updated in the 1990s, and eventually ...
The B28, originally Mark 28, was a thermonuclear bomb carried by U.S. tactical fighter bombers, attack aircraft and bomber aircraft. From 1962 to 1972 under the NATO nuclear weapons sharing program, American B28s also equipped six Europe-based Canadian CF-104 squadrons known as the RCAF Nuclear Strike Force.
The GBU-57A/B Massive Ordnance Penetrator (MOP) is a precision-guided, 30,000-pound (14,000 kg) "bunker buster" bomb used by the United States Air Force. [2] The GBU-57 (Guided Bomb Unit-57) is substantially larger than the deepest-penetrating bunker busters previously available, the 5,000-pound (2,300 kg) GBU-28 and GBU-37.
The Mark 7 was a major step in the evolution of the modern torpedo. This innovative design featured the use of steam , generated from water sprayed into the combustion pot along with the fuel . The resulting mixture dramatically boosted the efficiency of the torpedo, leading to markedly improved performance. [3]
