Former Air Force Base Transitioning to High-Tech Industrial Park and Commercial Airport

Shortly after the start of the Korean War in 1950, the Department of Defense designed and authorized the Corps of Engineers to construct as quickly as possible an array of 28 advanced radar stations, one of which was the nearby Calumet Air Force Station. K. I. Sawyer was one of several Air Force bases that were built to scramble fighters to intercept suspected threats. It’s located in the upper peninsula of Michigan just south of Marquette. Later in 1959, the Sault Sainte Marie Air Defense Sector was established and built/operated the Semi-Automatic Ground Environment (SAGE) Data Center at Sawyer to provide early warning for a Soviet nuclear attack. The base operated for nearly 40 years and closed in 1995.

K. I. Sawyer Airport was named after a civil engineer, Kenneth Ingalls Sawyer, who saw the need for aviation to help the Upper Peninsula mining industry expand in the 1930s. Construction of the airport was completed in 1945. The U.S. government signed a 99 year lease in January 1955 and construction of military support facilities at K. I. Sawyer Air Force Base began.

K. I. Sawyer Air Force Base is now decommissioned. Today Sawyer International Airport occupies a portion of the base and encompasses 2,100 Acres, has a 9,070’ x 150’ runway, air traffic control tower, service for commercial and private aviation, precision approach navigational system, 1,220+ raw acres of land for development, & 1 million square feet of office/storage space for lease.

The airport is the most active in the Upper Peninsula with 101,991 passengers in 2021. It is located approximately 15 minutes from downtown Marquette, the regional capital of Michigan's Upper Peninsula. Delta and American Airlines have multiple daily flights to Sawyer from Chicago and Detroit. There are several international companies that call Sawyer home like PotlatchDeltic, Adler Lumber, Superior Extrusion, National Carbon Technologies, Argonics Inc., Able Medical Devices, M.J. VanDamme, Inc., and Envoy Air.
