Boeing's Harpoon Missile System is an all-weather, over-the-horizon, anti-ship weapon that is extremely versatile. The U.S. started developing the Harpoon in 1965 to target surfaced submarines up to 24 miles away, hence its name "Harpoon," a weapon to kill "whales," a naval slang term used to describe submarines.
It was a slow moving project at first until the Six-Day War of 1967 between Israel and Egypt. During the war, Egypt sunk the Israel destroyer INS Eilat from 14 miles away with Soviet-made Styx anti-ship missiles launched from a tiny patrol boat. It was the first ship in history to be sunk by anti-ship missiles.
The surface-to-surface destruction shocked senior U.S. Navy officers; after all, it was the height of the Cold War, and the weapon indirectly alerted the U.S. of Soviet capabilities at sea. In 1970 Admiral Elmo Zumwalt—then Chief of Naval Operations—accelerated the Harpoon project, strategically adapting it for deployment from air and sea. Seven years later, the first Harpoon was successfully deployed.

Today, the U.S. and its allies—more than 30 countries around the world—are the primary users of the weapon. 2017 marks its 50th anniversary, and it's only getting better with age. Over the decades, the missile has been updated to include navigation technology, such as GPS, Inertial navigation system (INS), and other electronics to make it more accurate and versatile against ships and a variety of land-based targets.
