Location

Moses Lake, United States

Grant County International Airport (MWH) is located in Moses Lake, Washington, in the Columbia Basin region of the Pacific Northwest. Originally developed as Larson Air Force Base during World War II, it was transferred to civilian use after the base closed in 1966 and has since grown into a significant general aviation and cargo facility. The airport is notable for its exceptionally long runways, a legacy of its military origins, which make it attractive for heavy cargo operations, aircraft testing, and training flights. The longest runway stretches over 13,500 feet, one of the longest civilian runways in the United States. Grant County International serves as a base for cargo carriers and aviation training companies, and has hosted operations related to aircraft maintenance and storage. Its remote location and vast airspace make it especially suitable for flight training and test operations.
