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 ...
Modern U.S. Navy aircraft carriers have the Mark 7 Mod 3 arresting gear installed, which have the capability of recovering a 50,000-pound (23 t) aircraft at an engaging speed of 130 knots (240 km/h; 150 mph) in a distance of 344 feet (105 m) in two seconds.
The Mk-28RI (Retarded Internal) weapon was designed released in April 1959 and achieved production in June 1960. The design weighed 2,265 pounds (1,027 kg) and was 132 inches (3,400 mm) long. The design consisted of the Mk-28 Mod 2 Fuze and the same Mk-28 Mod 0 RESC as the RE weapon. It also used the Mod 1 warhead.
Mod 11 was a Mod 7 that had the chamber lengthened, adding 235 cu in (3,851 cm 3), and a 3½° breech band seating slope and used Breech Mechanism Mark 12. 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 ...
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.
The Mk 7 Mod 6 bomb dispenser is the same as the Mk 7 Mod 3 except that the outside of the Mod 6 cargo section is coated with a thermal protective coating and has an additional yellow band around the forward end of the cargo section. The addition of the thermal coating increases the overall weight of the Mod 6 to 505 pounds (229 kg).
Israeli Mark 37E torpedo. The mod 1 torpedoes were longer, slower and heavier than mod 0, but offered better target acquisition capabilities and higher ability to intercept agile submarines. They used wire-guidance. The efficiency of Mk37 torpedoes was high for targets with speed lower than 20 knots (37 km/h) and depth less than 1,000 ft (300 m).
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]
