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 Mark 7 gun was a built-up gun and was constructed of liner, tube, jacket, three hoops, two locking rings, tube and liner locking ring, yoke ring and screw box liner. Some components were autofretted. Typical of United States naval weapons built in the 1940s, the bore was chromium-plated for longer barrel life.
Mark 6 – Improved version of Mk-4. (8–160 kilotons, 1951–1962) Mark 7 – Multi-purpose tactical bomb. (8–61 kilotons, 1952–1967) Mark 8 – Gun-assembly, HEU weapon designed for penetrating hardened targets. (25–30 kilotons, 1951–1957) Mark 10 – Improved version of Mk-8 (12–15 kilotons, cancelled May 1952).
The Mark VII includes an adjustable trigger (retrofittable to Mark I pistols). The Mark I and VII are both available in .357 Magnum and .44 Magnum; the Mark VII has been chambered for .41 Magnum. The barrels have a 3 ⁄ 8 in dovetail, to which an accessory mount can be attached. Later Mark VII models were offered in .50 Action Express with a 7 ...
Believed to be either 0.3–340 kt [3] or 0.3–400 kt [4] in the weapon's various mods. The B61 nuclear bomb is the primary thermonuclear gravity bomb in the United States Enduring Stockpile following the end of the Cold War. It is a low-to-intermediate yield strategic and tactical nuclear weapon featuring a two-stage radiation implosion design.
Contact, airburst. The W93 is an American nuclear warhead planned to replace the W76 and W88 warheads on United States Navy submarines from 2034. The warhead will be carried on the new Columbia-class submarines [1] and will use a new aeroshell, the Mark 7 reentry body (RB). [2] The warhead will be designed by Los Alamos National Laboratory.

The 12-inch (305 mm)/50 caliber Mark 7 naval gun was only a slight improvement over the preceding American naval gun, the 12"/45 caliber Mark 5 gun.As such, it was a very similar weapon, having been lengthened by five calibers to allow for improved muzzle velocity, range, and penetrating power.
The weapon is similar to the SCAR Mk 16 Mod 0 but with modifications including a 140 g (0.3 lb) weight reduction resulting in a loaded weight of 3.61 kg (7.95 lb), a bayonet lug for an M9 bayonet (which the Mk 16 does not have), a rail mounted folding front iron sight instead of the gas block mounted sight, and a non-reciprocating charging handle.
