Harpoon Missile System

The AGM-84D Harpoon is an all weather over-the horizon, anti-ship missile system. The AGM84E SLAM is an infra red Stand-Off Land Attack Missile used for long range precision strikes. The SLAM-ER (Expanded Response) is an upgrade currently in production in the US. SLAM-ER has a greater range (150+ Miles), a titanium warhead for increased penetration, plus guidance improvements which allow the pilot to retarget the point of impact during the final phase of attack (about the last five miles).

The missile's active radar guidance, warhead design, and low level, sea skimming, cruise trajectory give it high survivability and effectiveness. The missile is capable of being launched from surface vessels, submarines and aircraft (without booster).

The missile was developed for naval use as it's basic anti-ship weapon. First introduced into service by the USN in 1977.
