Air Test and Evaluation Squadron Two Three (VX-23) is NAVAIR's largest flight test organization. The squadron's mission is to support the RDT&E of fixed wing tactical aircraft by providing aircraft and pilot assets, maintenance services, safety oversight and facility support for these efforts. Primary areas of support include flying qualities and performance evaluations, shipboard suitability, propulsion system testing, tactical aircraft mission system testing, ordnance compatibility and ballistic efforts, reliability and maintainability assessments, flight fidelity simulation and flight control software development. The Squadron also provides Government Flight Representatives, test monitoring, chase aircraft support, and facilities for contractor demonstration, validation and development work involving tactical aircraft and associated systems.
The VX-23 workforce -- officers (Navy, Marine Corps and foreign nationals), enlisted (Navy and Marine Corps), civilians and contractors -- supports the aircraft maintenance, test planning and conduct, safety oversight and support of the squadron's F/A-18A-D Hornets, F/A-18E/F Super Hornets, EA-18G Growlers, and T-45A/C Goshawk aircraft, and the on-going contractor demonstration efforts with F-35B/C Lighting II aircraft. VX-23 is also supported by hundreds of flight test engineers and technicians provided by the Integrated Systems, Evaluation, Experimentation and Test Department and various contractors.
The squadron conducts more than 3,000 flight operations annually, totaling approximately 4,400 flight hours, much of which involves high-risk flight test. VX-23 conducts operations, both shore based and shipboard, locally at NAS Patuxent River and operates and maintains the TC-7 catapult and MK-7 arresting gear test sites.
