defense contracts include the price for more items than just the cost of the aircraft. These items may include costs such as spare parts, flight simulators, tooling, support equipment, and manpower to maintain the aircraft.

"To derive the accurate cost of the aircraft, it is necessary to remove those additional items from the total and divide the recurring aircraft costs by the quantity in each lot. The following are the accurate aircraft unit costs by lot by aircraft variant.

procurement of support equipment at Pilot Training Center 1, Luke Air Force Base for the F-35 Lightning II Conventional Take-Off and Landing air system program

procurement of Australian-specific non-recurring sustainment activities to include procurement of Autonomic Logistics Information System equipment, and sustainment and logistics support to government non-recurring engineering activities

procurement of special tooling and special test equipment for the U.S. Navy, U.S. Air Force and the international partners, which is critical to preserving the current F-35 delivery schedules and meeting future production rates

initial lay-in of consumable piece parts for repair of repairables at U.S. government organic depots and original equipment manufacturers in support of the F-35 Lightning II Program

This modification provides for the non-recurring technical efforts for manufacturing technology transfer and planning tasks required to ensure a manufacturing base with sufficient technical knowledge is established to support F-35 production requirements
