AGM-84D Harpoon

Description: The Harpoon is an all weather, subsonic, over the horizon, anti-ship missile which can be launch from surface ships, submarines and aircraft. Its guidance system consists of a 3-axis integrated digital computer/ radar altimeter for midcourse guidance, and an active radar seeker for the terminal phase of the flight.

The Harpoon flies at subsonic speeds, with a sea-skimming flight trajectory for improved survivability through reduced probability of detection by enemy defenses. It was designed to strike enemy ships in an open ocean environment.

The aircraft launched AGM-84 Harpoon was introduced in 1979. It can be released from many aircraft types and doesn't have the solid fuel booster of the ship and submarine launched Harpoons. The current AGM-84D was fielded in 1985. More advanced versions were planned but they were cancelled due to the Soviet Union collapse.
