General: This round is a modified 100-pound G.P. bomb fastened to a 4.5-inch rocket motor.

Constrcution: Suspension lugs and base plug are removed from the standard 100-pound bomb, and a motor adapter substituted for the base plug. The motor is the stan-dard type for the 4.5-inch Army folding-fin type of rocket, modified to take the special box-type fin. The fuze seat in the bomb is modified to receive the Point Detonating Fuze T20.

Launcher: The metal crate in which the round is shipped serves as an expendable launcher.
