The US Air Force received the 1,000th JASSM in April 2010, and awarded a Lot 9 production contract for 170 baseline (JASSM) and 30 Extended Range (JASSM-ER) missiles in 2011. A $243.5m contract was awarded for JASSM Lot 8 production in February 2010. The company received a $107m contract from the USAF for Lot 7 production of JASSM in June 2008. In January 2007, Lockheed Martin was awarded with Lot 6 JASSM production contract. The US Air Force placed a $112.25m Lot 4 production contract with Lockheed for 288 AGM-158 JASSMs in December 2004. The US Navy awarded a $53m contract for the integration of its JASSMs on its F/A-18E/F aircraft in May 2003. "The JASSM is installed with hard target smart fuse (HTSF), which differentiates between the earth, concrete, rock and air." Lockheed Martin received a $33.58m contract from Tyndall Air Force Base in January 2002, to supply 76 JASSMs and 84 anti-jam GPS receivers for the JASSM. JASSM propulsion systemĪ Teledyne J402-100 turbojet engine powers the JASSM, whereas the JASSM-ER is equipped with a Williams International turbofan engine. The 1,000lb class WDU-42/B (J-1000) penetrating warhead consists of 240lb of extremely insensitive explosive (AFX-757). The FMU-156/B fuse used in the warhead of JASSM employs a 150-gram PBXN-9 booster. The JASSM is installed with hard target smart fuse (HTSF), which differentiates between the earth, concrete, rock and air. The J-1000 warhead is designed with a dense metal case, or contains dense metal ballast for maximum penetration. It can also carry powered low cost autonomous attack system (LOCAAS) sub-munitions integrating a dual mode laser detection and ranging (LADAR) system and a millimetre wave (MMW) seeker. The JASSM flies automatically through a predetermined route by using the onboard inertial navigation system that includes Anti-Jam Global Positioning System (AJGPS), and a ring laser gyro inertial measurement unit.Īdditional navigation and guidance features on the air-to-surface missile include an imaging infrared (I2R) seeker, and automatic target correlator (ATC) for high precision strike rate. Guidance and navigation features of JASSM JASSM can cruise with a subsonic speed, and has a range of 370.4km with the ability to reach targets within the range of 926km. It can carry warheads weighing up to 450kg. The missile has a length of 4.35m and weighs approximately 1,000kg. It is installed with a dual-mode penetrator and blast fragmentation warhead. The JASSM is a stealthy cruise missile integrating flip-out wings and a vertical tail. Design features and specifications of JASSM The JASSM completed a successful Product Verification Test (PVT) in July 2011. In March 2007 Lockheed Martin was awarded a $21m JASSM-ER Phase II development contract for procurement of 12 JASSM-ER operational test assets for additional testing. The USAF awarded a $32m contract in April 2006 for the development of a Weapon Data Link (WDL) capability enabling the JASSM-ER system to engage relocatable targets. Lockheed Martin’s JASSM-ER successfully performed its first development flight test in May 2006 and second flight test in August 2006. The final development test of JASSM was conducted in March 2003 and the missile was certified for meeting warfighter requirements and operational capability in October 2003. The JASSM proved its ability to perform in the presence of jammers in September 2002. Lockheed Martin received an extension of programme definition and risk reduction contract in support of EMD in March 1999.Ī first development test (DT-1) of the JASSM was successfully conducted in January 2001, and the operational capabilities of JASSM were subsequently demonstrated in April 2002.
