The accident
On 5 December 1965, 31 days after Ticonderoga's departure from U.S. Naval Base Subic Bay in the Philippines,[4] the attack jet fell over the side during a training exercise while being rolled from the number 2 hangar bay to the number 2 elevator.[3] The pilot, Lieutenant (junior grade) Douglas M. Webster; the aircraft, Douglas A-4E BuNo 151022 of VA-56; and the B43 nuclear bomb were never recovered[6] from the 16,000 ft (4,900 m) depth.[1] The accident was said to occur 68 miles (59 nmi; 109 km) from Kikai Island, Kagoshima Prefecture, Japan.[7]
Ticonderoga had aboard Carrier Air Wing Five during this cruise, with two squadrons of Skyhawks, the other being VA-144.[8]
Revelation
It was not until 1989 that US DoD revealed the loss of the one-megaton H-bomb.[9] The revelation inspired a diplomatic inquiry from Japan requesting details.[10]
