British Bomb, 250 lb Chemical, Mk 1, Mk 2




The 250 pound LC air bombs were fuzed bombs of conventional appearance. (Note: There were two types of 250 pound air bombs, Mk I and Mk II. The difference was in the structural modifications, which did not alter the contaminating performance of the bomb or affect its method of release.) They functioned on impact by the tail ejector principle, in which a small internal burster blew off a lightly welded tail plate. Limited numbers of 250 pound phosgene filled bombs were stored. The 250 pound mustard filled bombs had a high terminal velocity, which was an advantage when roof penetration was required for contaminating the inside of buildings.
