McGinn Airfield is a former United States Army Air Forces airfield located on Mount McGinn in the Aleutian Islands, Alaska. Constructed during World War II as part of the Aleutian Islands Campaign logistics and defense network, the airfield later served transient civil and research aviation roles before partial abandonment. The site intersects histories of United States Army Air Forces, United States Geological Survey, United States Fish and Wildlife Service, North Pacific Ocean navigation, and Cold War-era Arctic strategy.
McGinn Airfield was established in 1942 following losses at Dutch Harbor and the Battle of Attu as part of a rapid buildup that included Adak Army Airfield, Amchitka Army Airfield, and Kodiak Army Airfield. Construction teams drawn from Seabees, U.S. Army Corps of Engineers, and civilian contractors emplaced runways, fuel dumps, and radar installations to support Thirteenth Air Force and reconnaissance squadrons operating against Japanese forces in the North Pacific. During 1943–1944 the field hosted patrols coordinated with North American B-25 Mitchell medium bombers, Consolidated PBY Catalina flying boats, and Lockheed P-38 Lightning fighters staging between bases such as Attu Airfield and Adak Island. After World War II the airfield’s strategic importance declined with the closure of many Aleutian defense sites and the emergence of Long Range Radar networks; ownership shifted through War Assets Administration disposals and federal land management transfers to agencies such as the Bureau of Land Management and later the United States Fish and Wildlife Service as part of Aleutian refuges. Cold War considerations briefly revived interest in Aleutian airstrips alongside DEW Line planning and NORAD regional infrastructure, but McGinn remained primarily a local logistical hub.
McGinn featured a single asphalt runway initially graded for heavy bombers and later reduced in operational status to accommodate light transports and rotary-wing craft. The layout included taxiways, revetments, an operations blockhouse, fuel farms built to War Department specifications, and a radar station sited on an adjacent ridge. Support buildings comprised barracks modeled on Quonset hut designs, maintenance hangars capable of servicing Curtiss P-40 Warhawk and Grumman F4F Wildcat class aircraft, and a radio communications compound equipped with shortwave transmitters compatible with Huff-Duff direction-finding sets. Navigational aids incorporated non-directional beacons (NDB) interoperable with Civil Aeronautics Authority procedures and visual approach aids used by civilian carriers operating under Pan American World Airways and regional operators in later decades. Perimeter defenses originally paralleled standards applied at Fort Glenn and Shemya Army Airfield.
During wartime the airfield supported anti-shipping patrols, search and rescue coordinated with United States Coast Guard cutters and Catalina squadrons, and logistical sorties supplying forward bases such as Kiska Island. Postwar operations shifted to meteorological observation missions linked to the National Weather Service, geological surveys conducted by the United States Geological Survey, and wildlife monitoring by the United States Fish and Wildlife Service and Alaska Department of Fish and Game. Civilian charter flights by companies with ties to Alaska Airlines and regional freight services used the field intermittently for access to remote Aleutian communities and fishing camps tied to the Bering Sea harvest. Scientific expeditions studying seabird populations, volcanic geology associated with the Aleutian Arc, and climate research from institutions such as University of Alaska Fairbanks also staged operations at McGinn. Emergency use protocols were coordinated with Federal Aviation Administration flight service stations and Civil Air Patrol units during search operations.
Operational history includes weather-related incidents typical of the North Pacific theater, including runway overruns and forced off-field landings during subarctic cyclone events. Notable wartime occurrences involved damage to transient aircraft during severe crosswind episodes and corrosion-related failures attributed to marine exposure; affected types included B-25 Mitchell and P-38 Lightning airframes. Postwar reports filed with the Civil Aeronautics Board and later National Transportation Safety Board mention loss-of-control landings and mechanical failures on decommissioning-era flights, some resulting in airframe write-offs but few fatalities owing to prompt United States Coast Guard and Ketchikan-area rescue assistance. Environmental remediation actions followed incidents involving fuel spillage, tracked through interagency cooperation with the Environmental Protection Agency and Alaska Department of Environmental Conservation.
The airfield’s establishment altered local landscapes and subsistence patterns for Aleut communities affiliated with Unangan settlements and regional villages such as Adak, Alaska and Atka, Alaska. Military construction affected bird nesting habitats important to Aleutian tern and black-legged kittiwake populations while fueling programs introduced hydrocarbon contamination sites that required remediation under Comprehensive Environmental Response, Compensation, and Liability Act frameworks. Contemporary management by the United States Fish and Wildlife Service and consultation with tribal governments, including Aleut Community of St. Paul Island and Aleut Corporation, emphasize habitat restoration, cultural resource protection, and limited public access for subsistence use. Ongoing research partnerships with National Oceanic and Atmospheric Administration and academic programs monitor changing permafrost, sea-level influences from Pacific Decadal Oscillation phases, and invasive species pathways linked to postwar infrastructure.
