All mission critical support vehicles involved in the NW transport operation are owned by D NM&NARG. The vehicles were purchased by the MOD for use in their then current role from the Royal Air Force (RAF) Nuclear Weapon Convoy Group and transferred to D NM&NARG en bloc in 2002. [2] Prior to 2002 the RAF were in commanding roles during NW ...
The Mark 4 nuclear bomb was an American implosion-type nuclear bomb based on the earlier Mark 3 Fat Man design, used in the Trinity test and the bombing of Nagasaki.With the Mark 3 needing each individual component to be hand-assembled by only highly trained technicians under closely controlled conditions, the purpose of the Mark 4 was to produce an atomic weapon as a practical piece of ordnance.
The Mark 36 bomb was 56.2 to 59 inches (143 to 150 cm) in diameter, depending on version, and 150 inches (3.8 m) long. It weighed 17,500 or 17,700 pounds (7,900 or 8,000 kg) depending on version. There were two major variants, conventional ("dirty") weapon designated the Y1 and a low fission fraction "clean" Y2 version. [ 3 ]

[2] 200 Mk 17s and 105 Mk 24s were produced, all between October 1954 and November 1955. The Mark 17 and Mark 24 were identical in all respects save for the design of their primary section. [2] They were the largest nuclear weapons ever put into service by the United States; only the Convair B-36 Peacemaker was capable of carrying them. [3]
Early models of the Mark 6 used the same 32-point implosion system design concept as the earlier Mark 4 and Mark 3; the Mark 6 Mod 2 and later used a different, 60-point implosion system. Various models and pit options gave nuclear yields of 18, 26, 80, 154, and 160 kilotons for Mark 6 models.
Fire-control was provided by a Kongsberg SM-3 computer which could cue the missiles based on either active radar or passive ESM data. [3] The Penguin can be fired singly or in coordinated-arrival salvoes. Once launched the launching craft is free to turn away as the missile is inertially guided until the autonomous terminal homing phase.
