Harpoon Missile - One of the U.S. Navy's Anti-Surface Warfare Missiles

The Harpoon missile is an all-weather, over-the-horizon, anti-ship missile system
that provides the Navy with a common missile for both air and ship launches.
Specifically, the Harpoon was initially designed as an open-ocean weapon.

Harpoon Block II offers the following improvements:
* improved targeting
* an expanded engagement envelope
* enhanced resistance to electronic countermeasures

These key improvements to the Harpoon Block II were obtained by incorporating the
inertial measurement unit from the Joint Direct Attack Munition program, and the
software, computer, Global Positioning System (GPS)/inertial navigation system
and GPS antenna/receiver from the SLAM Expanded Response (SLAM-ER), an
upgrade to the SLAM.
