Ladd Army Airfield — Fairbanks, United States

FBK is the code for Ladd Army Airfield, a military airfield in Fairbanks, Alaska, operated in support of U.S. Army aviation units stationed at Fort Wainwright. Originally established decades ago as a strategic Arctic aviation installation, Ladd has long served cold-weather military flight training and logistics given Alaska's unique operational environment. The airfield supports helicopter and fixed-wing units conducting Arctic and subarctic training exercises, taking advantage of Fairbanks' extreme winter conditions to prepare personnel and aircraft for cold-region deployments. FBK is distinct from Fairbanks International Airport, which handles the city's civilian air traffic; Ladd instead remains dedicated to Army operations, logistics support, and readiness training tied to Fort Wainwright's mission in the interior Alaska region.
