Officially Licensed US Navy HX-21 Blackjacks Sticker — Air Test and Evaluation Squadron 21 Blackjacks Vinyl Sticker
Blackjacks — HX-21's rotary-wing test and evaluation as a vinyl sticker.
Air Test and Evaluation Squadron 21 (HX-21) "Blackjacks" is a United States Navy test squadron based at NAS Patuxent River, Maryland, responsible for the developmental testing and evaluation of rotary-wing and tiltrotor aircraft. This vinyl sticker brings the Blackjacks' test and evaluation identity to everyday items.
HX-21 conducts developmental flight testing on virtually every rotary-wing and tiltrotor aircraft in the Navy and Marine Corps inventory, including the MH-60R/S Seahawk, CH-53K King Stallion, MV-22B/CMV-22B Osprey, UH-1Y Venom, AH-1Z Viper, and the MQ-8B Fire Scout unmanned helicopter. Operating under the Naval Air Warfare Center Aircraft Division (NAWC-AD) at Pax River, HX-21's test pilots, engineers, and project officers push these aircraft to their limits, expanding flight envelopes, verifying performance claims, and identifying deficiencies before the aircraft reach the fleet. The Blackjacks are the gatekeepers of rotary-wing aviation safety and capability — if it spins, tilts, or hovers, HX-21 tests it.
This sticker represents HX-21's test mission.
Perfect For: HX-21 Blackjacks personnel, rotary-wing test pilots and engineers, NAS Patuxent River professionals, and test and evaluation squadron vinyl sticker collectors.
Blackjacks test it — HX-21.
