Quick Facts

Testing Planes for Arctic Extremes

Ladd Field was established near Fairbanks in 1940, as a Cold Weather Test Station to test military aircraft, equipment and clothing in arctic conditions. In 1942, Ladd Field became the northern end of the Alaska-Siberia (ALSIB) route, which began in Great Falls, Montana, to facilitate the transfer of Lend-Lease aircraft to Soviet Union.

Activated in 1940, the mission of the Cold Weather Test Detachment was to ensure that all military aircraft could operate in extreme cold conditions, down to -60 degrees Fahrenheit. Cold weather operation and maintenance requirements were established at Ladd Field, with aeronautics manufacturers from across the nation coming there to test aircraft and equipment. In addition to aircraft, cold weather experimentation was carried out on uniforms and flight suits at Ladd Field. In 1943, the Army’s first helicopter, the YR-4, underwent cold weather testing there.

Alaska to Siberia Military Aircraft Transfer

The ALSIB route consisted of a series of airfields constructed in Canada and Alaska to facilitate the transfer of Lend-Lease aircraft to Russia. Between 1942 and 1945 nearly 8,000 U.S. military aircraft were transferred to Russian aircrews at Ladd Field as part of the Lend-Lease Program. From Ladd Field the airmen flew the aircraft west across the Bering Strait for use in Russia’s war with Germany on its Eastern Front. Despite Alaska's harsh winters this air route was preferred over the longer Miami- South America-Africa-Moscow route. Soviet diplomats and missions also traveled through Ladd Field during the War on their way to and from the Soviet Union.

World War II Operations

World War II had a major impact on Ladd Field. The Cold Weather Test Station opened in 1940 with 214 enlisted men. At the time of the Japanese attack on Pearl Harbor in December 1941 the station had expanded to 520 personnel. With the Japanese invasion of Attu and Kiska in June 1942, Ladd Field's mission expanded to support the war effort. In October 1943 the Air Transport Command (ATC) was established at Ladd Field to facilitate Lend-Lease activities. Between 1943 and 1945 Ladd Field's small permanent garrison of 23 buildings grew to over 700 and at its height housed over 4,500 men.

Since Ladd Field's designation as a National Historic Landmark in 1985, a significant portion of the contributing buildings no longer remain. Ladd Field is one of eight national historic landmarks that commemorate World War II in Alaska.
