Hill fighter wings conducting night flying into April Published March 30, 2022 388th Fighter Wing Public Affairs HILL AIR FORCE BASE, Utah -- F-35A pilots in the 419th Fighter Wing and 388th Fighter Wing will conduct local night-flying operations most weekdays this week through April 11. During this period, flying is scheduled to be completed by approximately 10:30 p.m., but days and times may vary based on a number of factors including weather, airspace availability on the Utah Test and Training Range, and other support elements. Hill’s fighter wings must train at night to maintain their combat readiness and all-weather capabilities. Night flying is limited to what is required for pilots to remain proficient in those skills. Hill AFB is home to 78 F-35A Lightning IIs. The active-duty 388th FW and Reserve 419th FW are the Air Force's first combat-capable F-35A units. They fly and maintain the jet in a Total Force partnership, which capitalizes on the strength of both components.
