This page from a 1971 U.S. Air Force weapons delivery manual provides ballistic release data for the Mk 82 High Drag (Mk-82HD) bomb, a retarded general-purpose bomb designed for low-altitude delivery. Tables like this were essential references for fighter-bomber crews, including F-4 Phantom squadrons flying from Da Nang Air Base, South Vietnam, allowing pilots to calculate the correct dive angle, release altitude, and airspeed for accurate weapons delivery while minimizing risk from bomb fragmentation at low altitude.
