The AGM-158 JASSM

About the AGM-158 JASSM:





The Lockheed Martin AGM-158 Joint Air-to-Surface Standoff Missile (JASSM) is a next generation, precision guided, long range standoff cruise missile enabling the U.S. Air Force to destroy the enemy's war sustaining capability from outside its area air defenses. JASSM is a conventionally armed low observable, subsonic cruise missile designed to destroy high-value targets. JASSM can be delivered from both fighters and bombers. The JASSM is produced in a Baseline variant (AGM-158A) as well as an extended range AGM-158B (JASSM-ER) variant.

JASSM has automatic target recognition, autonomous guidance, precision accuracy, and a J-1000 warhead optimized for penetration. These characteristics give JASSM strong capabilities against heavily defended hard targets such as aircraft shelters and underground command posts, as well as soft targets such as rail yards. JASSM's accuracy of three meters or less reduces the number of weapons and sorties required to destroy a target. The missiles employ an Imaging InfraRed (IIR) seeker system and use GPS/INS for midcourse navigation and as a back up for terminal guidance. Missile launch can occur over a wide range of altitudes and at ranges greater than 200 nm (230 miles/370 km) for the AGM-158A Baseline missile and greater than 500 nm (575 miles/926 km) for the AGM-158B Extended Range variant.

JASSM carries the WDU-42B (J-1000), a 1000-pound class penetrating warhead with 240 pounds of AFX-757. AFX-757 is an extremely insensitive explosive developed by the Air Force Research Laboratory at Eglin Air Force Base (AFB) in Florida. The fuze is the FMU-156B employing a 150-gram PBXN-9 booster.

The Air Force procurement objective is 2,034 JASSM Baseline missiles (through 2016) and 2,978 JASSM-ER (through 2023). The U.S. Navy has funded six JASSM Baseline development missiles but not purchased production missiles.

JASSM has entered foreign service in Australia (RAAF) and Finland (Finnish Air Force) and in September 2015, the Polish Air Force ordered JASSMs for its F-16 fleet.

In July/August 2012, the final eleven JASSM-ER test flights were flown, completing 16 flight tests with 16 successes. This cleared the JASSM program for Full-Rate Production and paved the way for the JASSM-ER Initial Operational Capability (IOC). In January 2012, the final flight test required to integrate JASSM on the F-15E Strike Eagle was successfully completed. On December 15, 2014, Lockheed Martin announced that the U.S. Air Force had approved the JASSM-ER for full rate production (FRP).

Lockheed Martin manufactures JASSM missiles at its facility in Troy, Alabama. On August 12, 2015, Lockheed Martin celebrated the opening of a new 64,500-square-foot Cruise Missile Annex in Troy, where it will produce JASSMs and Long Range Anti-Ship Missiles (LRASMs). Key JASSM suppliers are Continental Motors (J402 engine for JASSM baseline), Williams International (F107 engine for JASSM-ER), and Exelis, which provides composite missile bodies and structures for both the baseline and ER versions.

On December 19, 2013, Lockheed Martin was awarded $449 million in contracts by the Air Force for the production of 340 AGM-158A missiles and 100 AGM-158B missiles (Lot 11 and Lot 12). On October 15, 2015, Lockheed Martin received a $305 million contract from the Air Force for continued JASSM production. The Lot 13 contract includes 140 JASSM Baseline missiles for U.S. and international partners, 140 JASSM-ER missiles, data, tooling and test equipment.



Applications/Platforms:

The baseline AGM-158 JASSM is integrated on the B-52 Stratofortress, F-15E Strike Eagle, F-16 Fighting Falcon (Block 50), B-1B Lancer, and B-2 Spirit. Future applications include the F-16 Fighting Falcon (Block 40), F/A-18E/F Super Hornet, and F-35 Lightning II. The extra-range AGM-158B (JASSM-ER) can currently only be employed by the B-1B Lancer, but future applications will include the F-15E Strike Eagle, F-16 Fighting Falcon (Block 25-42 and 50/52), the F-35 Lightning II, and the B-2 Spirit. Internationally, JASSM is integrated on Royal Australian Air Force F/A-18A/B Hornets.



Price/Unit Cost:

The unit cost of the AGM-158A JASSM Baseline missile is $0.83 million per All-Up Round (in FY 2014). The AGM-158B JASSM-ER costs $1.28 million per All-Up Round (in FY 2015).



Total Cost - Life of Program (LoP):

The total procurement cost of the JASSM program is $5.94 billion (estimated by the DoD) + $1.28 billion in research and development (RDT&E) funds, which means the total estimated program cost is $7.22 billion (numbers are aggregated annual funds spent over the life of the program and no price/inflation adjustment was made).



Mission/Role:

The mission of the JASSM is to destroy targets from a long-range standoff position deliverable by fighter and bomber aircraft. JASSM employment will occur primarily in the early stages of conflict before air superiority has been established as well as in the later stages of conflict against remaining, heavily defended high value targets.



FY 2015 JASSM DoD Program:

Continues Full Rate Production (FRP) of JASSM while JASSM-ER FRP is planned for FY 2015. The Air Force will award a lot 13 production contract for 215 JASSM missiles in FY 2015 (100 JASSM Baseline missiles and 115 JASSM-ER missiles). FY 2015 provides $329.2 million in procurement funds and $12.9 million for RDT&E.



FY 2016 JASSM DoD Program:

In FY 2016, the Air Force will award the lot 14 production contract, which will include 100 JASSM baseline missiles, and the second FRP for 260 JASSM-ER missiles. The Air Force will continue reliability initiatives including Weapon System Evaluation Program (WSEP) flight testing of current production missiles and continue evaluating Diminishing Manufacturing Sources (DMS) material shortages. FY 2016 provides $440.6 million in procurement funds and $12.8 million for RDT&E.
