The F-35 ADAL (Addition and Alteration) Training Facility supports maintenance training requirements for F-35A aircraft at Eielson Air Force Base. The renovation of Building 4280 includes a 24,000 SF addition to the existing facility. The 4,000 SF renovation allows space for instructor-led training, self-paced study via interactive work stations, and mock-ups of various F-35A components. The project will provide administrative offices, team meeting/conference rooms, student break room, and student work stations. Training rooms are required for various F-35A maintenance training functions.
