A Hawaii Air National Guard F-22 Raptor, from the 199th Fighter Squadron, flies away from a Wisconsin Air National Guard KC-135 Stratotanker Dec. 11, 2018, after receiving an air-to-air refueling during fighter-exercise Sentry Aloha near the Hawaiian Islands. Sentry Aloha provides tailored, cost effective and realistic combat training for U.S. Air Force, Air National Guard and other Department of Defense services to provide U.S. warfighters with the skill sets necessary to perform their homeland defense and overseas combat missions.
