The Harpoon is an all-weather, over-the-horizon, anti-ship missile manufactured by McDonnell Douglas (now Boeing Defense, Space & Security). The regular Harpoon uses active radar homing and flies just above the water to evade defenses. The missile can be launched from:

• Fixed-wing aircraft (AGM-84), without the solid-fuel rocket booster
• Surface ships (RGM-84), fitted with a solid-fuel rocket booster that detaches when expended, to allow the missile's main turbojet to maintain flight
• Submarines (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 (RGM-84), from which it would be fired with a solid-fuel rocket booster.

The Harpoon has also been adapted for carriage on several aircraft, including the P-3 Orion, the P-8 Poseidon, the AV-8B Harrier II, the F/A-18 Hornet and the U.S. Air Force B-52H bombers. The Harpoon was purchased by many nations, including India, Japan, Singapore, South Korea, Taiwan, the United Arab Emirates and most NATO countries.

Currently only the Air-dropped AGM-84L version is available ingame.
