This 1971 technical manual page details ballistic reference data used by U.S. Air Force fighter-bomber crews, including F-4 Phantom squadrons operating from Da Nang Air Base, South Vietnam. The upper table calculates bomb release timing for multi-weapon strings, while the lower table lists drag coefficients for common ordnance of the era, the Mk 82 bomb, M-117 bomb, and CBU-24 cluster munition, essential for accurate weapons delivery during dive-bombing and toss-bombing attacks.
