Frequently asked questions
Is KGRF open to civilian transient aircraft?
KGRF, Gray AAF at Joint Base Lewis-McChord, is a military-use airfield with restricted civilian access. Transient aircraft require prior permission 72 hours in advance, and no transient traffic is accepted on weekends or holidays. Base operations, the tower, and weather service run Monday through Friday only and are closed on holidays. Any inbound flight planning must coordinate through base operations before arrival.
What fuel is available at Gray AAF?
Gray AAF (KGRF) carries military-grade fuel with limited supply, and NATO F24 is also available. Fuel service is tied to a transient alert window rather than continuous coverage. Because supply is described as limited, operators should confirm availability with base operations before planning a fuel stop rather than assuming uplift capacity on arrival.
What is the main runway configuration at KGRF?
KGRF operates a single paved runway, 15/33, measuring 6,124 feet long and 150 feet wide with an asphalt surface. The field also has three helipads, each 100 by 100 feet with an asphalt-concrete surface. There is no parallel or crosswind runway, so all fixed-wing operations funnel through the one strip at this Joint Base Lewis-McChord airfield.
Does KGRF have onsite customs clearance?
Gray AAF (KGRF) does not have onsite customs processing. The nearest customs facility is McChord Field, about 5.52 nautical miles away. Operators requiring customs clearance near Fort Lewis / Tacoma should plan to route through that facility rather than expecting service at Gray AAF itself.
