Body Construction: The body consists of three pieces welded together; a concave nose, parallel sides, and a tapered base to receive the clip-on tail. The after end is clo-sed off by the closing plate, which houses the exploder container. A round nose cap, at-tached to the nose for streamlining during air travel, breaks off on impact, giving the bomb an unstable trajectory, and so preventing ricochet. |
|
Tail Construction: The clip-on type tail consists of a cylindrical strut secured to the tail cone by four fins. The tail cone is constructed of four pieces and is held together by three rivets only. There is no reach rod extending through the tail cone, as the fuze is not the arming-vane type. The tail breaks off on impact with water, contributing to the unstable trajectory of the bomb. |
|
Suspension: The bomb may be suspended from British planes by the single lug, or from U.S. aircraft by the dual lugs on either side of the single lug. When either dual lugs or the single lug are used, the remaining lug screw holes are closed by transit screws. |
