Dated 15 July 1971, this table lists the precise minimum release altitudes for the ordnance carried by F-4 Phantom fighter-bombers during the Vietnam War, including napalm, MK-82 and MK-84 general-purpose bombs, CBU-46 cluster munitions, and unguided rockets, broken down by dive angle and day or night conditions. These figures reflect the exacting calculations behind every strike mission flown from Da Nang Air Base, balancing weapons effectiveness against the aircrew's safe escape from the blast and fragmentation pattern.
