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 off Japan from the aircraft carrier USS Ticonderoga.

Naval Base Subic Bay in the Philippines,[3] the attack jet was pushed backwards over the side, off the number 2 elevator during a training exercise while being rolled from the number 2 hangar bay to the elevator.

[citation needed] 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.
