An F-35A assigned to the 33rd Fighter Wing takes off January 31, 2017, at Eglin Air Force Base, Florida. The 33rd Fighter Wing loaded and shot the first air-to-air missiles from an F-35A during a weapons system evaluation that took place at Tyndall Air Force Base later the same day. Carrying air-to-air missiles makes the F-35 a more versatile option for combatant commanders by securing the aircrafts survivability, in turn increasing likeliness of mission success.
