The sub-sonic, wave-skimming GM-84 Harpoon is the US Navy’s sole anti-shipping missile, with the minor exception of small helicopter-borne AGM-119B Penguin missiles. The Harpoon has been adapted into several variants, and exported to many navies around the world. At present, the Harpoon family includes AGM-84 air, RGM-84 sea/land, and UGM-84 submarine-launched versions. Variants such as the Joint Standoff Land Attack Missiles and the upgraded AGM-84K SLAM – Expanded Response will also be covered in this DID FOCUS Article. It describes the missiles themselves, and covers global contracts involving this family.
