British Bomb, 450 lb DC, Mk 7
The body consists of a welded cylindrical case, closed by two covers connected by a central tube called the primer tube. This tube, housing the primer, pistol, and depth adjuster, has an internal diameter of 3.5 in. Three lifting eyes with rings are provided, one on the cover at the primer end, and two on the cover at the opposite end. The cover at the primer end has two filling holes which are closed by bungs. It may or may not have a nose attachment and tail. The bomb is carried on aircraft with the primer end forward, except when fitted with the parachute attachment, in which case the pistol and depth adjuster are forward.
The bomb may use a hemispherical hollow nose held on by the side straps, which also secure the tail assembly.
The tail, when fitted, consists of a cylindrical strut attached to a hollow tail cone by four fins. Three brackets, equispaced around the cone, are fitted to take the ends of the straps which secure the nose and tail attachments, both of which break off on impact with water. The bomb may have a parachute attachment on the primer end if dropped from high-speed aircraft.
The bomb is suspended by a single lug on a suspension band around the center of gravity.
