AGM-154A Joint Standoff Weapon (JSOW)

The AGM-154A Joint Standoff Weapon or JSOW is currently under development by Raytheon (Texas Instruments) for the Air Force and the Navy. The AGM-154A (Formerly Advanced Interdiction Weapon System) is intended to provide a low cost, highly lethal glide weapon with a standoff capability. JSOW family of kinematically efficient, air-to-surface glide weapons, in the 1,000-lb class, provides standoff capabilities from 15 nautical miles (low altitude launch) to 40 nautical miles (high altitude launch). The JSOW will be used against a variety of land and sea targets and will operate from ranges outside enemy point defenses. The JSOW is a launch and leave weapon that employs a tightly coupled Global Positioning System (GPS)/Inertial Navigation System (INS), and is capable of day/night and adverse weather operations. The JSOW uses inertial and global positioning system for midcourse navigation and imaging infra-red and datalink for terminal homing.

The JSOW is just over 13 feet in length and weighs between 1000-1500 pounds. Extra flexibility has been engineered into the AGM-154A by its modular design, which allows several different submunitions, unitary warheads, or non-lethal payloads to be carried. The JSOW will be delivered in three variants, each of which uses a common air vehicle, or truck, while substituting various payloads.

AGM-154A AGM-154B AGM-154C

AGM-154A (Baseline JSOW) The warhead of the AGM-154A consists of 145 BLU-97/B submunitions. Each bomblet is designed for multi-target in one payload. The bomblets have a shaped charge for armor defeat capability, a fragmenting case for material destruction, and a zirconium ring for incendiary effects.

AGM-154B (Anti-Armor) The warhead for the AGM-154B is the BLU-108/B from the Air Force's Sensor Fuzed Weapon (SFW) program. The JSOW will carry six BLU-108/B submunitions. Each submunition releases four projectiles (total of 24 per weapons) that use infrared sensors to detect targets. Upon detection, the projectile detonates, creating an explosively formed, shaped charge capable of penetrating reinforced armor targets.

AGM-154C (Unitary Variant) The AGM-154C will use a combination of an Imaging Infrared (IIR) terminal seeker and a two-way data link to achieve point target accuracy through aimpoint refinement and man-in-the-loop guidance. The AGM-154C will carry the BLU-111/B variant of the MK-82, 500- pound general purpose bomb, equipped with the FMU-152 Joint Programmable Fuze (JPF) and is designed to attack point targets.
