Allen Army Airfield (BIG)

Allen Army Airfield (BIG) is a unique joint-use aviation facility located at Fort Greely, approximately three miles south of Delta Junction, Alaska. Owned and operated by the United States Army, the airfield serves a dual role as a critical logistics hub for military operations in the Arctic and a public-use airport for the local community. This joint-use facility operates at 1,285 feet above sea level with three paved asphalt runways: the impressive 9,000 by 150-foot Runway 1/19, capable of accommodating heavy military cargo aircraft such as the C-17 Globemaster III and C-5A Galaxy (December-April), plus runways 10/28 (6,115 by 150 feet) and 7/25 (4,057 by 90 feet). This strategic infrastructure is essential for the testing of cold-climate equipment and the support of the U.S. Army's mission at Fort Greely.

The passenger facilities at Allen Army Airfield are minimalist, reflecting its primary function as an active military installation. There is no traditional commercial passenger terminal with retail or extensive dining halls. Instead, civilian travelers and personnel using the airfield for charter or private flights will find basic waiting areas and administrative offices. Amenities are limited to the essentials, and there are no restaurants or cafes within the airport territory. Travelers are strongly advised to bring their own provisions, including water and snacks, or to utilize the dining options available in the nearby town of Delta Junction. The airport's layout is focused on operational utility, ensuring the efficient movement of personnel and cargo across the Southeast Fairbanks Census Area.

Operational procedures at BIG are strictly managed by military personnel, and civilian use is governed by a long-standing agreement with the City of Delta Junction. The airfield is generally active from 8 a.m. to midnight, Monday through Friday, with specialized hours for air traffic control and refueling services. Security is a paramount concern, and all civilian visitors must comply with military base access requirements and potential enhanced screening measures. For those arriving on private or charter aircraft, it is recommended to coordinate with the base command well in advance to ensure all necessary permits and clearances are in place. The airport also features a massive 37,600-square-foot hangar capable of housing large helicopters like the CH-47 Chinook.

Ground transportation from the airfield is oriented toward private vehicles and pre-arranged shuttles, as there is no regular public transit serving the base. The drive to the center of Delta Junction typically takes about 5 to 10 minutes via local roads. The airport serves as an important entry point for those visiting the region for military business or for exploring the dramatic landscapes of the Alaskan interior, including the nearby Alaska Range. While the facilities are basic, Allen Army Airfield provides a professional and highly secure environment that reflects its critical role in national defense and regional connectivity. Whether arriving for cold-weather training or as part of a specialized logistical mission, BIG offers a resilient gateway to the heart of Alaska.
