They’re all fired up.

U.S. Air Force F-22 pilots said they’re excited the stealthy fifth-generation fighter jets are now armed with the new AIM-9X sidewinder missile.

Already on the F-15, F-16, F/A-18 and other fighter and attack aircraft since the 2000s, the AIM-9X was integrated in the Raptor fleet only last year.

The 9X Block 1 version of the dual-use, infrared missile is “a dramatic leap within visual range missile capabilities,” said Lt. Col. Daniel, an F-22 pilot of the 95th Fighter Squadron at Tyndall Air Force Base in Florida.

Military.com recently interviewed a few pilots and a maintainer at the base, who spoke on the condition that their last names not be used due to safety concerns amid ongoing air operations against the Islamic State of Iraq and Syria, or ISIS.

The new AIM-9X is part of the incremental 3.2 upgrade to the aircraft. (The AIM-9 missile pictured above, as noted by the blue stripe, is an inert dummy.)
