This 1971 technical reference page from a U.S. Air Force weapons delivery manual provides ballistic data for level bombing deliveries of the Mk-84 2,000-pound general-purpose bomb. Used by F-4 Phantom aircrew operating from Da Nang Air Base during the Vietnam War, such tables allowed pilots to calculate the correct release altitude, sighting angle (in mils), and escape maneuver needed to safely deliver ordnance while avoiding the weapon's own fragmentation pattern.
