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 (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.
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.
Texas Instruments (TI) Defense Systems & Electronics (DS&E) began Engineering and Manufacturing Development (E&MD) of JSOW in 1992. In December 1995, the Navy and Texas Instruments completed Development Test IIB (DT-IIB) at the Naval Air Weapon Center, (NAWC) China Lake and Point Mugu, California, with 10 for 11 successful flights of the AGM-154A BLU-97 dispenser variant.
On January 6, 1997, it was announced that Texas Instruments Defense Systems & Electronics was being purchased by Raytheon Company, Lexington, Massachusetts. The U.S. Navy began Operational Evaluation (OPEVAL) testing in February 1997, after successful development testing and initial operational testing programs. The test program resulted in a 42 for 44 success rate or greater than 96% successful JSOW launches. The Air Force began Development Test & Evaluation (DT&E) flight testing of JSOW on the F-16 at Eglin Air Force Base, Florida, in March 1996. Air Force testing of the baseline JSOW was hindered by less than desired progress in the area of F-16/JSOW integration. There was never a problem in the
interface between the weapon and the aircraft. The weapon worked perfectly. The problem that prolonged the testing at Eglin, was with a subassembly of the JSOW, which was not manufactured by Texas Instruments.
AGM-154A (Baseline variant) system entered Low Rate Initial Production (LRIP) on schedule. The $65.9 million LRIP contract was awarded by the Naval Air Systems Command (NAVAIR), in Arlington, Virginia, for 111 JSOW AGM-154A/baseline systems. LRIP for the other two variants are scheduled for FY99 and FY00, respectively. On 29 December 1998 Raytheon Systems was awarded a $133,881,355 firm-fixed-price contract to provide funding for the Full Rate Production Lot 1 of JSOW AGM-154A and the Low Rate Initial Production Lot I of the JSOW AGM-154B (AGM-154A: Navy - 328 and Air Force - 75) (AGM-154B: Navy - 3 and Air Force - 21). Work is expected to be completed by March 2001.
JSOW test articles were deployed in 1997 aboard the USS Nimitz and are currently deployed on the USS Eisenhower. JSOW initial introduction to the operational commands was on the Navy/Marine Corps F/A-18 in mid-1998. As of late 1997 a number of remaining JSOW test assets were on an interim deployment for further operational evaluation. USS Carl Vinson 's air wing first employed the JSOW during combat over southern Iraq on Jan. 25, 1999.
On 29 December 1999 Raytheon Systems Company, Tucson, Ariz., was awarded a $109,573,867 modification to previously awarded contract N00019-99-C-1014 to exercise an option for the full rate production Lot 2 of the Joint Standoff Weapon AGM-154A for the U.S. Navy (414) and U.S. Air Force (74). Work will be performed in Tucson, Ariz., and was expected to be completed by March 2002.
On 23 June 2000 Raytheon was awarded a $5,069,914 modification to previously awarded cost plus incentive fee basic ordering agreement N00019-98-G-0104 for the integration of the Selective Availability Anti-Spoofing Module (SAASM) into the Joint Standoff Weapon (JSOW) System. This effort will bring new production JSOWs delivered after 1 April 2003 in compliance with current Global Positioning System (GPS) security requirements for weapon-based GPS. Work will be performed in Tucson, Ariz., and is expected to be completed by May 2001.
Weapon planning will be accomplished using the Navy's Tactical Automated Mission Planning System (TAMPS) and the Air Force Mission Support System (AFMSS). Aircraft-to-weapon communications will be via the MIL-STD-1760 interface, making inflight programming/targeting possible, as well as preflight data loading. The weapon will be deployed from both carrier- and land-based aircraft, employing insensitive munitions technology. The JSOW will be employed on the following aircraft: F/A-18A/B, C/D, and E/F; AV-8B; F-14A/B and /D; F-16C/D; F-15E; F-117; B-1B; and B-52.
