The USAF has taken delivery of the first production lot of Lockheed Martin JASSM-ER missiles.
The JASSM-ER is a longer range version of the 400km range JASSM which is in service with the USAF and RAAF. Using the same mould line as the JASSM the –ER has a repackaged warhead and engine module which allows more fuel to be carried. It will be initially be integrated with the B-1B Lancer bomber, and can fly up to 1,000km to a highly defended target autonomously.
“The initial delivery of the extended range variant of JASSM gives the combatant commander the ability to reach far deeper into contested areas with lethal precision,” MajGen Scott Jansson, the USAF program executive officer for Weapons and Armament said in a statement.
The USAF has plans to integrate the JASSM-ER onto the B-52H, F-15E and F-16C/D.
