BODY CONSTRUCTION:

This bomb consists of a U.S. 20 lb. Fragmentation Bomb, altered by attachment of a British parachute housing. The bomb consists of cast steel and tail sections threaded to a seamless steel liner tube. Helically wrapped around this inner steel tube is a heavy drawn steel wire to provide effective fragmentation. The nose and tail section are threaded internally, the former to receive the nose fuze, the latter to receive the para-chute housing.

TAIL CONSTRUCTION:

The British No. 14 parachute housing consists of a cast aluminum tray containing a 12" diameter parachute. The tray is closed by a loosely fitting metal lid, to which the parachute is attached by a short loop of cord. The shroud lines of the parachute are fitted through holes drilled around the bottom edge of the tray and are secured by a metal ring passed through the loops of the lines. Leading from the parachute is an arm-ing line spliced to the arming wire from the fuze. Release of the parachute withdrawn the arming wire from the fuze, allowing the fuze to arm after a few seconds delay.

SUSPENSION:

Althrough the bomb is provided with a single U-shaped steel eye-bolt welded to the bomb body for individual suspension, these bombs will be carried by the R.A.F. in cluster projectiles No. 23 Mk I and No. 24 Mk I. In these clusters the nose of one bomb bears against the parachute lid of the one behind it, holding the lid in place until the cluster opens. The air slip then removes the housing lid, which acts as a pilot parachute and pulls out the 12" diameter parachute by which the bomb is suspended.

REMARKS:

1. Because of the extreme sensitivity of the AN-M 104 fuze, an extra spring, located outside the fuze body beneath the pressure plate, is added when this fuze is employed in these bombs by the R.A.F.
