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 centimetres and a wingspan of 91.4 centimetres. 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 usesactive radar homing, and a low-level,sea-skimmingcruise trajectory to improve survivability and lethality. The missile's launch platforms include:
Surface ships (theRGM-84, fitted with a solid-fuel rocket booster that detaches when expended, to allow the missile's mainturbojet to maintain flight)
Fixed-wing aircraft (theAGM-84, without thesolid-fuel rocketbooster)
Submarines (theUGM-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.
