Aircraft
The film features U.S. Air Force A-1 Skyraiders and an HH-3 "Jolly Green Giant" rescue helicopter in various action sequences, with brief appearances of Navy aircraft including the A-7 Corsair, C-2 Greyhound and the F-4 Phantom II, as well as a North Vietnamese MiG-17.
Two early variants of the A-6 Intruder, the A-6A and A-6B, are portrayed in the film by A-6E (without the TRAM targeting equipment) as all surviving A-6 variants at the time of filming had been updated to A-6E or KA-6D standards. The A-6A is a conventional bomber and the A-6B carried specialized electronics and weapons for Suppression of Enemy Air Defenses missions (the Navy called this "Iron Hand", the Air Force called it "Wild Weasel".)
The Shilka anti-aircraft vehicle seen at the end was never used during the Vietnam War. Its first combat use was during the Yom Kippur War in 1973.
