Английская Википедия:B43 nuclear bomb
The B43 was a United States air-dropped variable yield thermonuclear weapon used by a wide variety of fighter bomber and bomber aircraft.
The B43 was developed from 1956 by Los Alamos National Laboratory, entering production in 1959. It entered service in April 1961. Total production was 2,000 weapons, ending in 1965. Some variants were parachute-retarded and featured a ribbon parachute.
The B43 was built in two variants, Mod 1 and Mod 2, each with five yield options. Depending on version, the B43 was Шаблон:Cvt in diameter, and length was between Шаблон:Cvt and Шаблон:Cvt. The various versions weighed between Шаблон:Cvt. It could be delivered at altitudes as low as Шаблон:Cvt, with fuzing options for airburst, ground burst, free fall, contact, or laydown delivery. Explosive yield varied from 70 kilotons of TNT to 1 megaton of TNT.
The B43 used the Tsetse primary design for its fission stage, as did several mid- and late-1950s designs.
The B43 was one of four thermonuclear gravity bombs carried by Canadian CF-104 jets while serving in Germany between June 1964 and 1972.[1]
Delivery systems
Carrier aircraft 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, B-58A Hustler, F-100 Super Sabre, F-105 Thunderchief, F-4 Phantom II, F-104 Starfighter, FB-111A strategic bomber variant, 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, though it remains unclear whether this particular aircraft was ever type-approved to carry the B43 prior to the B-1's reassignment to conventional strike roles. The B43 was also supplied for delivery by Royal Air Force Canberra and Valiant aircraft assigned to NATO under the command of SACEUR.
Broken Arrow
Шаблон:Main The B43 was never used in combat, but it was involved in a nuclear accident when an A-4E Skyhawk, BuNo 151022, of the USS Ticonderoga (CVA-14) (from Attack Squadron VA-56), was lost off the coast of Japan on 5 December 1965 when it rolled off an elevator, in Шаблон:Cvt of water in the Pacific Ocean, Шаблон:Cvt from Kikai Island, Kagoshima Prefecture, Japan.[2] The Skyhawk was being rolled out of the number 2 hangar bay, onto the number 2 elevator, when it continued over the edge and was lost.[3] Neither the pilot LTJG D. M. Webster, airframe, nor the bomb were ever recovered.[4] No public mention was made of the incident at the time and it would not come to light until a 1989 US DoD report revealed that one of these one-megaton bomb (which had recently been retired from service and replaced) had gone missing.[5] Japan then asked for details of the incident.[6]
Withdrawn
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.
