An Eglin Air Force Base F-35A Lightning II receives fuel from a KC-135 Stratotanker assigned to MacDill AFB approximately 100 miles off the Gulf Coast March 2, 2016 following the 58th Fighter Squadron's first successful munition employment at a nearby range. Airmen from the 33rd Fighter Wing were able to complete modifications to the aircraft ahead of schedule to enable the use of inert munitions instead of simulated weapons, advancing the fifth-generation fighter's syllabus and ensuring pilots receive the most comprehensive training before they support a combat-coded F-35A unit. The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, all-weather stealth multirole fighters undergoing final development and testing by the United States. The fifth generation combat aircraft is designed to perform ground attack, and air defense missions. This multi-role fighter can perform on air defense missions, close air support and tactical bombing. It is compatible with the latest air-to-air and air-to-ground missiles.
