British Bomb, 4000 lb MC, Mk 1, Mk 2
In the Bomb Mk I the exploder containers screw into the nose and male base plate. The body has parallel sides, an ogival nose, and a slight taper at the body base. It is similar in appearance to US General Purpose Bombs. The Bomb Mk II has a strengthened after end due to better welding.
Toil Construction: The bomb employs a short type tail unit, consisting of cylindrical strut attached to a tail cone by four fins. A reach rod, having arming vanes at its rear, extends through the tail cone and engages the arming fork of the tail pistol.
The bomb has a single lug 44 in. from the nose fuze tip, for regular suspension, and dual lugs 30 in. apart diametrically opposite the single lug for suspension from US aircraft.
Tail fins are usually painted red when a time pistol is used.
