The 1965 Philippine Sea A-4 crash was a Broken Arrow incident in which a United States Navy Douglas A-4E Skyhawk attack aircraft carrying a nuclear weapon fell into the sea from the aircraft carrier USS Ticonderoga.[5]

The accident[]

On 5 December 1965, 31 days after Ticonderoga's departure from U.S. Naval Base Subic Bay in the Philippines,[5] 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 Attack Squadron 56; and the B43 nuclear bomb were never recovered[6] from the 16,000 ft (4,900 m) depth.[1] The accident occurred 80 miles (130 km) from Okinawa.[2][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 the 1980s that the Pentagon revealed the loss of the one-megaton bomb.[9] The revelation inspired a diplomatic inquiry from Japan requesting details.[10]
