Raytheon has successfully completed fit-checks for the AGM-154C-1 Joint Standoff Weapon (JSOW C-1) in the internal carriage bay of the Lockheed Martin F-35 Joint Strike Fighter (JSF). The checks ensured that the weapon fitted into the bay with sufficient clearance for the doors to operate unhindered.

JSOW C-1 will add a significant attack capability to the JSF’s repertoire. It is the latest member of the modular JSOW family, and Raytheon claims it is the world’s first net-enabled standoff weapon. The weapon uses an integrated GPS inertial navigation system with imaging infrared terminal guidance, and has been used widely in combat in both its AGM-154A version (with combined effects warhead) and the AGM-154C (with a unitary Broach warhead). The weapon is unpowered, but has a glide range of over 60 miles.

Also known as JSOW Block III, the C-1 version was developed using company funds and adds a two-way strike common data link. This gives the weapon a maritime moving target capability, enabling it to perform anti-ship attacks as well as its primary land-attack duties. The first free-flight test was performed on July 26 this year, the weapon being launched from a Boeing F/A-18F Super Hornet.

Separately, Raytheon has developed a wireless interface for the Enhanced Paveway dual-mode (GPS/IMU and laser) guided bomb, enabling the weapon to be carried by aircraft that cannot currently support it without major wiring modifications and changes to the stores management system.

Called WiPak, the system comprises a small wireless transmitter and pilot interface in the cockpit, and a small receiver unit on the Paveway weapon. They connect using technology similar to that employed in consumer devices.

WiPak has completed testing, and has already been integrated into the Embraer Super Tucano light attack aircraft. Raytheon is now working on testing and deploying WiPak on other aircraft types.
