Harpoon (missile)
The Harpoon is an all-weather, over-the-horizon, anti-ship missile manufactured by McDonnell Douglas (now Boeing Defense, Space & Security). The AGM-84E Standoff Land Attack Missile (SLAM) and later AGM-84H/K SLAM-ER (Standoff Land Attack Missile – Expanded Response) are cruise missile variants.

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
