R- 2508 Airspace Complex
Over a large area of the upper Mojave Desert and souther Sierra Nevada is a special military-use airspace "complex" known as R-2508. This complex stretches approximately 140 miles from north to south (Bishop to Edwards Air Force Base) and 100 miles east to west (the Nevada State Line to Tehachapi.) This airspace overlies large amounts of public land - including Death Valley National Park!
Where do they fly in the park?
In most of the park - the portion that was originally Death Valley National Monument - the military voluntary restricts their flight to 3,000 feet vertically and laterally (this started in 1977.) These flights will be high above you and you might not even notice them.
When do they fly?
Low level flying normally occurs during daylight hours, but night mission training and testing is performed to ensure pilot readiness and systems effectiveness in combat situations. Continuing technical advances in night vision systems may increase the number of night flights to test these systems.
What will you see and hear?
Military aircraft are built with sophisticated systems designed for speed and evasive tactics. Sometimes, you will not see or hear an aircraft approaching until it is directly overhead or nearby. There could be a sudden roar which can be startling, followed by a possible split second glimpse of a silhouette, then the aircraft is gone.
