The principal mission of VX-1 is to test and evaluate airborne anti-submarine warfare (ASW) and maritime anti-surface warfare (SUW) weapon systems, airborne strategic weapon systems, as well as support systems, equipment and materials in an operational environment. The squadron also develops, reviews and disseminates new ASW/SUW tactics and procedures for fleet use, serving as the model manager for all such tactical publications. This is their ‘bullet’ patch that says “TEST IN PROGRESS” and DOES come with velcro attached.
