If they don't fly, their reflexes and skills atrophy. Some are carrying people or equipment to other locations. And not every real-world mission will be flown in daylight, so they fly at night to keep those skills honed as well. The United States is one of the best militaries for night flights in combat.

Military aircraft frequently fly at night in 2026 for a variety of strategic and training reasons, primarily to maintain Night Vision Goggle (NVG) proficiency. Pilots must log a specific number of "night hours" to remain combat-ready, as modern warfare often prioritizes nighttime operations to maintain a tactical advantage over adversaries. These flights are not just about seeing in the dark; they involve complex maneuvers, low-altitude navigation, and carrier landings that are significantly more difficult without daylight. If you live near a coast or an airbase, you might also be hearing Case 3 Carrier Qualifications, where pilots practice landing on moving ships in total darkness. Furthermore, night flying allows the military to conduct exercises when civilian air traffic is lower, providing more "clear sky" for high-speed intercepts and formation drills. Occasionally, these flights are part of Strategic Deterrence, where a visible and audible presence signals readiness to global actors. While the noise can be disruptive, it is a sign of a rigorous training cycle designed to ensure that aircrews can operate effectively in 24-hour mission environments.
