B43 Nuclear Bomb Wings Over the Rockies Air and Space Museum

For more than twenty years the B43 was the United States' air-dropped nuclear weapon used by a wide variety of aircraft. The weapon was developed in 1956 by Los Alamos National Laboratory, entering service in April 1961. Total production was 2,000 weapons, ending in 1965. 

The B43 was built in three variants: Mod 0, Mod 1, and Mod 2, each with five yield options. Explosive yields varied from 70 kilotons of TNT to 1 megaton of TNT. The B-43 could be delivered at altitudes as low as 300 ft, with fusing options for air burst, ground burst, free fall, contact, or laydown delivery - a mode of deploying a free-fall nuclear weapon in which the bomb's fall is slowed by parachute so that it actually lands on the ground before detonating.

Aircraft that could carry the weapon included most USAF, USN and USMC fighters, bombers and attack aircraft, including the A-3 Skywarrior, A-4 Skyhawk, A-5 Vigilante, A-6 Intruder, A-7 Corsair II, B-47 Stratojet, B-52 Stratofortress, F-100 Super Saber, F-105 Thunderchief, F-4 Phantom Il, F-111 Aardvark, FB-111A, F-15E Strike Eagle, F-16 Fighting Falcon, and the F/A-18 Hornet. The B-1B Lancer was also intended to carry the B43 prior to the B-1's reassignment to conventional strike roles. The B43 was also supplied to Great Britain.

The B43 was never used in anger, but it was involved in a nuclear accident when an A-4 Skyhawk of the USS Ticonderoga from Attack Squadron VA-56 was lost off the coast of Japan on 5 December 1965. The aircraft, the pilot, and the bomb were never found.  

The B43 was phased out in the 1980s, and the last B43 weapons were retired in 1991 in favor of the newer B61 and B83 weapons.  

The upper weapon was used by Explosive Ordnance Disposal (EOD) teams to practice their skills on, while the lower weapon was used by aircraft ground crews to practice loading the weapon on various aircraft. The "spike" on the end of the weapon buried itself in the ground and kept the unit from being dragged by its parachute when the target was small and needed precision accuracy.
