Body Construction: The bomb body is a hollow steel casting having parallel sides, an ogival nose, and a slight taper at the after end. The exploder containers thread into the nose and male base plate. This bomb is similar in appearance to U.S. General Purpose Bombs.

Tail Construction: The tail assembly consists of a cylindrical strut attached to the tail cone by four sheet-metal fins. A reach rod with arming vanes on the after end ex-tends through the tail cone and engages an arming fork in the tail pistol. The tail is se-cured to the body by four wing bolts and retained in the tail ring by split pins. The arming vanes protrude beyond the cylindrical strut.

Suspension: The Bomb Mk I has a single suspension lug at the center of gravity at-tached to two step plates, and dual "U" bolt suspension lugs, 180 degrees removed from the single lug, for carrying in U.S. bomb racks. Both sets of lugs are welded onto the body. The Bomb Mk II has a strengthened form of U.S. lug for dive bombers.
