USAF places Lot 19 JASSM-ER order
JASSM-ER has a more fuel-efficient turbojet engine than the baseline missile.
The USAF will receive 400 Lot 19 AGM-158B Joint Air-to-Surface Standoff Missile-Extended Range (JASSM-ER) missiles from Lockheed Martin Missiles and Fire Control, under a new $428.41 million sole-source contract from the Air Force Life Cycle Management Center.
The manufacturer will also provide containers, training and production preparation, tooling and test equipment and hardware spares.
Lockheed Martin will carry out the work in Orlando, Florida, for completion by 31 July 2025.
JASSM-ER has a more fuel-efficient turbojet engine from Teledyne with greater fuel capacity, increasing the standoff range of the missile by 250% to more than 500nmi.
Customers include the US and Poland, while Finland could also receive the missile if it chooses the F-35 in the HX fighter competition.
