Description

The 1000-lb GP Bomb Mk 83 Mods 2 and 3 have a slender body with a long, pointed nose. A conical type fin is attached to the aft end of the bomb body by six setscrews.

Bomb Mk 83 uses either mechanical or electric fuzes. Mechanical fuzing requires installation of adapter-boosters. Two conduits for an electric fuze cable harness connect the nose and tail fuze cavities with the charging receptacle cavity between the lugs on the outer surface of the bomb case. When electric fuzes are not used, a plug is threaded into the charging receptacle cavity.

When fuzes are not installed, the bomb body has a nose fuze-hole plug, a base fuze-hole plug, and a support cup in the nose fuze cavity. When the bomb is fuzed mechanically, these three parts are removed and the adapter boosters and fuzes are inserted. The nose fuze-hole plug and base fuze-hole plug are replaced after electric fuzes have been installed. Adapter-boosters are not used with electric fuzes. If the bomb is tail-fuzed only, the support cup must be used in the nose fuze cavity to prevent collapse of the fuze cavity upon heavy impact.

The bomb body has a base plug containing locking pins which are imbedded in the solidified explosive filler. Double suspension lugs spaced 14 inches apart, and a hoisting lug at the center of gravity are threaded into lug inserts on the bomb body.

The high-explosive Tritonal filler is identified by yellow-stenciled nomenclature on the bomb. The base color of the bomb is olive drab.

Low drag GP Bomb Mk 83 consists of the Mod 2 and the Mod 3. Differences lie in the methods used in the construction of the bomb bodies.
