Body Construction: The body is a streamlined steel casting of forging, threaded at the nose to take the nose adapter, which holds the central exploder tube. At the other end of the casting is a threaded base plug through which the exploder tube passes. Wel-ded to the end of the casting is a streamlined section of thin metal, containing no explo-sive, which is tapered to take the tail ring. The exploder passes through this section also. |
|
Tail Construction: A truncated cone fits over the rear section of body and is held to it by a locknut over the exploder tube. Three mild-steel fins are fastened to the cone, and are reinforced by a cylindrical strut. |
|
Suspension: The bomb uses a single suspension lug secured to the body by four screws. |
