The US Air Force (USAF) has declared full operational capability (FOC) of the Lockheed Martin AGM-158B Joint Air-to-Surface Standoff Missile – Extended Range (JASSM-ER) missile on the Boeing F-15E Strike Eagle multirole strike fighter.

The USAF’s Seek Eagle Office – which leads the integration of the AGM-158 JASSM and AGM-158B JASSM-ER missiles on the F-15E Strike Eagle – declared FOC for JASSM-ER on the aircraft in the fourth quarter of 2017, although this was only publicly disclosed in early February 2018.

A Lockheed Martin release noted, “With the completion of integration and fielding of JASSM-ER’s Suite 8 Operational Flight Programme [the software programme of an embedded computer system which enables that system to perform its interactive tasks as designed] the F-15E Strike Eagle becomes the first Universal Armament Interface [UAI-compliant platform to field JASSM-ER.” A USAF programme of record, UAI is a US Department of Defense (DoD) initiative to develop a standardised interface for aircraft, weapons, and mission planning to support integration of future weapons independent of aircraft Operational Flight Program cycles. The baseline AGMA-158 JASSM was the first missile to be integrated on a UAI platform.

Externally identical in mold line and size to the baseline of AGM-158A JASSM, JASSM-ER is 4.26 m long, 450 mm high, and about 635 mm wide, with a deployed wing span of 2.7m as currently configured. Both variants share about 70% of their hardware and 95% of their software. With an estimated launch weight of 1,200 kg , and equipped with a 454 kg dual-mode penetrator/blast fragmentation warhead, the AGM-158B is a day/night all-weather capable weapon, furnished with an inertial navigation system (INS)/enhanced digital anti-jam GPS receiver to dial into specific target aimpoints, with an advanced imaging infrared seeker for terminal guidance. Powered by a Williams International F107-WR-105 turbofan engine – which replaces the Teledyne J402-100 turbojet engine in the baseline AGM-158A – and with an added fuel capacity that does not affect the payload or electronics capability, the JASSM-ER solution extends the missile’s range from 200 n miles to 500 n miles.
