DTN News: Boeing Flies Harpoon Missile With Updated Guidance Control

DTN News: Boeing Flies Harpoon Missile With Updated Guidance Control
*Source: DTN News / Boeing (NSI News Source Info) ST. LOUIS, USA - September 17, 2009: A Boeing [NYSE: BA] Harpoon Block II missile equipped with a redesigned Guidance Control Unit (GCU) flew for the first time in a test conducted on Sept. 10. It was launched from the USS Princeton off the coast of California and scored a direct hit on a land-based target on San Nicolas Island, Calif. Harpoon Block II expands the capabilities of the Harpoon anti-ship weapon. Harpoon, the world's most successful anti-ship missile, features autonomous, all-weather, over-the-horizon capability. Harpoon Block II provides accurate long-range guidance for land and ship targets by incorporating the low-cost inertial measuring unit from the Boeing Joint Direct Attack Munition, or JDAM, program; and the software, mission computer, integrated Global Positioning System/Inertial Navigation System and the GPS antenna and receiver from the Standoff Land Attack Missile Expanded Response, or SLAM-ER. Harpoon Block II is capable of executing both land-strike and anti-ship missions. To strike targets on land and ships in port, the missile uses GPS-aided inertial navigation to hit a designated target aimpoint. The 500-pound blast warhead delivers lethal firepower against a wide variety of land-based targets, including coastal defense sites, surface-to-air missile sites, exposed aircraft, port/industrial facilities and ships in port. For conventional anti-ship missions, such as open ocean or near-land, the GPS/INS improves midcourse guidance to the target area. The accurate navigation solution allows users to discriminate target ships from islands or other nearby land masses or ships. These Block II improvements maintain Harpoon's high hit probability even against ships very close to land. The new GCU, which controls most of the missile's functions, incorporates a Selective Availability Anti-Spoofing Module (SAASM) Global Positioning System (GPS) receiver to improve GPS security. In addition, the GCU resolves obsolescence issues and can accommodate possible future implementation of a data link for network centric operations. "The implementation of the new GCU reinforces Boeing's vision for Harpoon's long-term viability," said Jim Young, Boeing Harpoon/SLAM ER Weapons program manager. "Boeing's investment in this technology eliminates obsolescence and will give Harpoon customers a weapon system with the flexibility to upgrade to meet current and future needs." Boeing began developing the new GCU in 2007 to provide a common guidance system for Block II and future versions of the Harpoon missile. All new Harpoon missiles will incorporate the redesigned GCU. Boeing has delivered more than 7,100 Harpoon missiles to the United States and 28 allied partners. Harpoon Block II executes both anti-ship and land-strike missions. The 500-pound blast fragmentation warhead delivers lethal firepower against a variety of surface and land-based targets, including ships at sea, coastal defense sites, surface-to-air missile sites, exposed aircraft, port/industrial facilities and ships in port. A unit of The Boeing Company, Boeing Integrated Defense Systems is one of the world's largest space and defense businesses specializing in innovative and capabilities-driven customer solutions, and the world’s largest and most versatile manufacturer of military aircraft. Headquartered in St. Louis, Boeing Integrated Defense Systems is a $32 billion business with 70,000 employees worldwide.
