Bomb, 750 lb Chemical, MC-1
Description
The MC-1 750 pound bomb was used to provide toxic chemical offensive capability. The bomb was designed for internal or external carriage on bomber and fighter-bomber aircraft utilizing single or double lug suspension for release at altitudes up to 60,000 feet, and air speeds up to 600 knots. It was a general purpose bomb M117 modified to accommodate a liquid chemical filler and a burster.
The MC-1 bomb was essentially a M117 GP demolition bomb modified for a liquid chemical filler and burster. The complete bomb consisted of a body, fin assembly, one arming wire, three suspension lugs, a nose fuze, adapter-boosters, burster, filling agent, and a tail fuze, which included a tail fuze drive with a flex coupling that connected the drive to the tail fuze. The bomb body was round in a cross section with an ogival nose and truncated conical tail. A burster tube was welded to the body at the nose end and into a hole in the base plate at the rear. The burster tube was internally threaded at each end and was fitted with fuze wells. The burster was a tubular fiberboard container filled with Composition B and closed by metal end caps. It was installed in the burster tube when the bomb was assembled. For use with one or two lug suspensions on Air Force bomber and fighter-bomber type aircraft.
Hazardous Components
Gas bomb MC-1 is filled with 24 gallons of GB gas (220 lb, 99.7 kg).
The burster is a tubular fiberboard container filled with Composition B (14.5 lb 6.6 kg), and closed by metal end caps. It is installed in the burster tube when the complete round is assembled.
Adapter booster M126A1 (T45E1) is used with the nose fuze and adapter booster T46E4 is used with the tail fuze.
