The F-35 program has accomplished the final developmental test flight of the System Development and Demonstration (SDD) phase of the program.
Since the first flight of AA-1 in 2006, the developmental flight test program has operated for more than 11 years mishap-free, conducting more than 9,200 sorties, accumulating over 17,000 flight hours, and executing more than 65,000 test points to verify the design, durability, software, sensors, weapons capability and performance for all three F-35 variants.
While SDD required flight test is now complete, F-35 flight testing continues in support of phased capability improvements and modernization of the F-35 air system.
The final SDD flight occurred April 11, 2018, at Naval Air Station Patuxent River, Md., when Navy test aircraft CF-2 completed a mission to collect loads data while carrying external 2,000-pound GBU-31 Joint Direct Attack Munitions (JDAM) and AIM-9X Sidewinder heat-seeking missles.
From flight sciences to mission systems testing, the critical work completed by F-35 test teams cleared the way for the Block 3F capability to be delivered to the operational warfighter. More than a thousand SDD flight test engineers, maintainers, pilots and support personnel took the three variants of the F-35 to their full flight envelope to test aircraft performance and flying qualities.
The test team conducted 6 at-sea detachments and performed more than 1,500 vertical landing tests on the F-35B variant. The developmental flight test team completed 183 Weapon Separation Tests; 46 Weapons Delivery Accuracy tests; 33 Mission Effectiveness tests, which included numerous multi-ship missions of up to eight F-35s against advanced threats.
Developmental flight test is a key component of the F-35 program's SDD phase, which will formally be completed following an Operational Test and Evaluation and a Department of Defense decision to go into full-rate aircraft production.
This effort is part of the Joint Program Office's Continuous Capability Development and Delivery (C2D2) framework, which will provide timely, affordable incremental warfighting capability improvements to maintain joint air dominance against evolving threats to the United States and its allies.
