Body Construction: The body is a steel fabricated cylinder with a dome-shaped nose and parallel sides, and is closed by a flat plate bolted to a flange within the after end. The base flange is fitted with locating pins of the tail, and holes to receive the tail se-curing bolts are drilled through it. |
|
A central tube is cemented to the stem of the central exploder container in the nose, and extends through the body almost to the closing plate. All three nose fuzing positions house exploder containers, the two side ones extending radially inward toward the cen-tral tube. |
|
Tail Construction: The tail is a metal cylinder, having an angle ring secured at each end. Hand holes in the tail cylinder give access to the tail securing bolt, which thread through tapped bosses on the forward angle ring. Other holes in the cylinder provide sta-bility in flight. |
|
Suspension: The bomb uses a single suspension lug, 46 in. from the nose dome, se-cured by eight screw. |
