JSOW Program Achieves New Milestone

Released on Thursday, October 13, 2005

Raytheon Company's Joint Standoff Weapon Block II (JSOW Block II), a new variant offering significantly lower unit cost and an additional payload option, successfully flew its first captive test flight October 11 at Edwards Air Force Base on a U.S. Air Force F-16 aircraft.

Raytheon is under contract with U.S. Naval Air Systems Command and expects to complete development of the JSOW Block II in early 2006. Block II is planned to reduce JSOW unit cost approximately 40 percent. Cost reduction is achieved by reducing the parts count and improving the manufacturing process, an example of Raytheon's company-wide efforts to make operations leaner while providing superior products to customers.

All variants of future JSOW precision glide weapons will be manufactured in the Block II configuration. Block II will maintain all standoff and survivability capability of the current JSOW and will include an improved anti-jam Global Positioning System (GPS) receiver.

The Raptor GPS system is an advanced navigator developed by Raytheon Space and Airborne Systems and is planned for use in other Raytheon products.

Development of a new payload option for the JSOW A should be complete in early 2006. This new version will use a unitary 500-pound BLU-111 (MK-82) warhead and is designated the AGM-154A-1. This unitary variant will eliminate the unexploded ordnance concerns of cluster munitions while maintaining or increasing effectiveness against a broad target set. It is primarily intended for the international market.
