The AGM-84 Harpoon is an all-weather, over-the-horizon, anti-ship missile developed and manufactured by McDonnell Douglas.
It weighs 690.8 kilograms, has a diameter of 4.3 centimeters and a wingspan of 91.4 centimeters. It is 4.6 metres long, and has a range of 124 kilometres at high subsonic speed. Its low-level, sea-skimming cruise trajectory, active radar guidance and warhead design assure high survivability and effectiveness.
In 2004, Boeing delivered the 7,000th Harpoon unit it had built 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-skimmingcruise trajectory to improve survivability and lethality. The missile's launch platforms include:
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)
Fixed-wing aircraft (the AGM-84, without the solid-fuel rocket booster)
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.
