Air Test and Evaluation Squadron (VX) 20 Fact Sheet

Check out fact facts on VX-20!

Air Test and Evaluation Squadron TWO ZERO (VX 20) is a proud member of Naval Air Systems Command and traces its roots to the founding of Naval Air Station (NAS) Patuxent River, Maryland. Recognizing the need for Navy flight test effort consolidation, NAS Patuxent River was established on April 1, 1943. The location was selected due to coast proximity, air traffic congestion and isolation. On June 16, 1945, Naval Air Test Center (NATC) (Flight Test Division, Weapon Systems Test Division, Service Test Division, and the United States Naval Test Pilot School) was designated as the center for Navy flight test. In April 1975, NATC was reorganized into the Antisubmarine Aircraft Test Directorate, Strike Aircraft Test Directorate, Rotary Wing Aircraft Test Directorate, Systems Engineering Test Directorate, and the United States Naval Test Pilot School. In June 1986, the directorate was renamed Force Warfare Aircraft Test Directorate. In May 1995, the organization officially became a squadron and was renamed Naval Force Aircraft Test Squadron. In May 2002, the squadron was designated Air Test and Evaluation Squadron TWO ZERO. Throughout its history, the squadron supported the Fleet through the full spectrum test and evaluation of VS, VP, VAW, VRC, VQ, VR, VUP, VMGR, and VT community aircraft.

Current aircraft supporting test at VX-20 are the C-2A, C-12M, C-38, E-2C/D, E 6B, C/KC-130J/T, MQ-4C, P-8A, and T-6A.
