A Navy F-35C, a Marine Corps F-35B, and an Air Force F-35A Lightning II participate in a training sortie together May 21, 2014, near Eglin Air Force Base, Fla. The F-35 Integrated Training Center at Eglin AFB surpassed 5,000 combined training sorties May 28, 2014, contributing more than a third of all sorties in the Department of Defense’s F-35 program. All three variants of the fifth generation multirole stealth fighter are hosted by the 33rd Fighter Wing here. The F-35 is designed with the stealth, electronic warfare, and multi-spectral fused sensor capabilities, which will increase lethality and survivability in a contested environment.
