AGM-84 Harpoon, US Air to Surface Missile

The AGM-84 arpoon is an all-weather, over-the-horizon, anti-ship missile system, developed and manufactured by McDonnell Douglas. In 2004, Boeing delivered the 7,000th Harpoon unit since the weapon's introduction in 1977. The missile system has also been further developed into a land-strike weapon, the Standoff Land Attack Missile (SLAM).

The regular Harpoon uses active radar homing, and a low-level, sea-skimming cruise trajectory to improve survivability and lethality. The missile's launch platforms include:

• Fixed-wing aircraft (the AGM-84, without the solid-fuel rocket booster)
• Surface ships (the RGM-84, fitted with a solid-fuel rocket booster that detaches when expended, to allow the missile's main turbojet to maintain flight)
• Submarines (the UGM-84, fitted with a solid-fuel rocket booster and encapsulated in a container to enable submerged launch through a torpedo tube);
• Coastal defense batteries, from which it would be fired with a solid-fuel rocket booster.

The missile is comparable to the French-made Exocet missile, the Swedish RBS-15 missile, the Russian SS-N-25 Switchblade, the British Sea Eagle missile, and the Chinese Yingji.
