Mission The AGM-84D Harpoon is an all-weather, over-the-horizon, anti-ship missile system produced by McDonnell Douglas. Its low- level, sea-skimming cruise trajectory, active radar guidance, and warhead design assure high survivability and effectiveness. Features The AGM-84D Harpoon has been adapted for use on B-52G bombers, which can carry from eight to 12 missiles. Background Originally developed for the Navy to serve as its basic anti- ship missile for fleetwide use, the AGM-84D Harpoon also has been adapted for use on Air Combat Command's B-52G bombers. The 42nd Bombardment Wing, Loring Air Force Base, Maine, was first tasked to perform the Harpoon mission in 1985. The wing refined tactics and doctrine to merge the long-range, heavy-payload capability of the B-52 with the proven reliability of this superior stand-off attack weapon. This combines to provide the war-fighting capability to interdict ships at ranges well beyond those of other aircraft. General Characteristics Primary Function: Air-to-surface anti-ship missile.
