The B43 was built in two variants, Mod 1 and Mod 2, each with five yield options. Depending on version, length was between 12 ft 6 in and 13 ft 8 in (3.81 m and 4.15 m), with a weight of 2,060 lb to 2,125 lb (935 kg to 960 kg). It could be delivered at altitudes as low as 300 ft (90 m), with fusing options for airburst, ground burst, free fall, contact, or laydown delivery.
