Lockheed Martin Awarded $818 Million JASSM-ER Contract

Lockheed Martin Corp. has been awarded a firm-fixed-price contract, worth around $818 million, by the U.S. Air Force (USAF) for the production of JASSM-ER (Joint Air-to-Surface Standoff Missile-Extended Range) missiles.

The contract for JASSM Lot 17 and Lot 18 production, and will provide for 360 Lot 17 JASSM-Extended Range (ER) missiles; 40 Lot 17 Foreign Military Sales (FMS) JASSM-ER missiles; and 390 Lot 18 JASSM-ER missiles. The FMS customer was not revealed in the Pentagon contract announcement.

The contract work will be performed in Orlando, Florida, and is expected to be completed by Oct. 31, 2024.

This award is the result of a sole-source acquisition, and fiscal 2018 missile procurement funds in the amount of around $767.5 million; and FMS funds in the amount of around $50.7 million will be obligated at the time of the award. The U.S. Air Force Life Cycle Management Center (AFLCMC) at Eglin Air Force Base, Florida, is the contracting activity (FA8682-20-C-0001).


AGM-158B JASSM-ER (JASSM-Extended Range) is the extended range version of the JASSM (Joint Air-to-Surface Standoff Missile) low observable standoff air-launched cruise missile (ALCM) developed by Lockheed Martin for the U.S. Armed Forces.

Using a more efficient engine and larger fuel volume in an airframe with the same external dimensions as the JASSM, the JASSM-ER is intended to have a range of over 575 miles (925 km) as compared to the JASSM’s range of about 230 miles.

Other possible improvements were studied but ultimately not pursued, including a submunition dispenser warhead, new types of homing head, and a new engine giving ranges in excess of 620 miles (1,000 km). The JASSM-ER has 70% hardware commonality and 95% software commonality with the original AGM-158 JASSM.

The first flight test of the JASSM-ER occurred on May 18, 2006, when a missile was launched from a USAF B-1 bomber at the White Sands Missile Range in New Mexico. Although the B-1 was initially the only aircraft able to deploy it, it was later integrated onto the B-52, F-15E, and F-16.

Lockheed Martin JASSM-ER missile entered service with the USAF in April 2014.
