The US Air Force has awarded a $302.2m contract to Lockheed Martin for Lot 14 production of the joint air-to-surface standoff missile (JASSM) and its extended range (ER) version.
The contract covers 146 baseline JASSMs for US and international partners, 140 JASSM-ER missiles for the US, and data, tooling and test equipment.
The award brings the total number of missiles under contract to over 2,600. It follows the $305.4m contract for Lot 13 JASSM production in October for 140 baseline JASSMs and 140 JASSM-ER missiles.
Lockheed Martin said the contract represents the sixth production order for JASSM-ER, which secured full-rate production approval last year.
Lockheed Martin Missiles and Fire Control programme director of long-range strike systems Jason Denney said: "This Lot 14 contract continues to demonstrate how important JASSM's capability is to strategic defense planning.
"Lots 13 and 14 were negotiated together, resulting in cost savings that led to more affordable missiles for our customers."
JASSM is a long-range, conventional, air-to-ground, precision standoff missile designed to destroy high-value, well-defended, fixed and relocatable targets.
A 2,000-pound class weapon with a penetrator / blast fragmentation warhead, JASSM is equipped with precision routing and guidance in severe weather, day or night, using an infrared seeker and anti-jam GPS to identify a particular aimpoint on the target.
JASSM is integrated on multiple aircraft including the bombers B-1B, B-2, B-52, and fighter jets F-16 and F-15E. The B-1B also carries JASSM-ER.
Internationally, JASSM is certified on the Royal Australian Air Force's F/A-18.
Lockheed Martin is manufacturing JASSMs at its production facility in Troy, Alabama. The company has to date delivered over 1,800 JASSMs.
