Redstone Army Air Field — Redstone Arsnl Huntsville, United States

HUA is Redstone Army Air Field, a military airfield located within the Redstone Arsenal complex in Huntsville, Alabama. Unlike commercial Huntsville International Airport, HUA primarily supports U.S. Army aviation operations, including missile and space research activities tied to the arsenal's role in defense and NASA-adjacent programs. The airfield serves military aircraft, testing operations, and government personnel rather than the general public. Huntsville's identity as Rocket City owes much to the research conducted at Redstone Arsenal, and HUA plays a supporting logistical role in that mission. Access to HUA is restricted, reflecting its function as active military infrastructure rather than a public transportation hub.
