Description: The Joint Standoff Weapon (JSOW) is a modular, family of low-cost weapons designed for high precision strikes from well beyond enemy air defenses. The 3 baseline models carry several submunitions as the warhead or unitary blast fragmentation and penetration warheads. These warheads array enable JSOW gliders to attack soft area targets, armored vehicles and hardened point targets. JSOW also features low-signature/stealth design to engage actively defended targets.

The JSOW weapon variants are guided to the target by a GPS and INS aided navigation system. Target position can be updated by the launch aircraft or a third party through JSOW's on-board communication system. The C model is the only one provided with a seeker to be used in the terminal phase of the flight. The modular design allows future growth incorporating new sensors, warheads and submunitions. AGM-154's back section can accommodate a turbojet for extended range up to 220 kilometers.

Since 1999 the JSOW weapon has been employed successfully during military operations Southern Watch, Allied Force, Enduring Freedom (2002) and Iraqi Freedom (2003). The F-16, F/A-18, B-1, B-2, B-52, F-15E, F-35 and many other aircraft are compatible with the JSOW weapon. Total production for the US military is planned in excess of 20,000 units.

The Raytheon Joint Standoff Weapon Extended Range (JSOW ER) is a modified version of the AGM-154 glide weapon powered by TJ-150 150-pound thrust engine supplied by Hamilton Sundstrand. The resulting weapon has a extended range of up to 300 nautical miles and tag price of $350,000 which turns JSOW ER into a low-cost, long-range missile. The JSOW ER would incorporate those improvements developed under JSOW Block II and JSOW Block III efforts as well as new payloads. Raytheon started the prototype design and test in 2007. JSOW ER will conduct a free flight in 2008 and could be available for production in 2011.
