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 ...

Mod 12 used a Mod 10 and lengthened the chamber and added a 3½° breech band seating slope with Mod 13 being similar but of a Mod 8, Mod 14 used a Mod 9, Mod 15 used a Mod 7, Mod 16 used a ...
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]
[7] [6] The Mark 13 ran 12.8 knots (23.7 km/h; 14.7 mph) slower than the Mark 14 torpedo, a characteristic which, along with a lesser mass, lesser negative buoyancy and the lack of a magnetic influence feature in its Mark IV exploder, meant that it did not suffer from some of the same problems as its larger siblings.
Decks: 1.5–2.5 in (38–64 mm) The Wyoming class was a pair of dreadnought battleships built for the United States Navy. Wyoming and Arkansas were authorized in early 1909, and were built between 1910 and 1912.

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]
