OPERATIONS
Grant County International Airport
The Grant County International Airport boasts one of the largest airfields in the United States and is capable of accepting the largest aircraft in the world. The airport enjoys 350 days of excellent VFR weather and is regularly utilized by commercial and military flights. It has capacity to accommodate increased traffic given the five runways and onsite FAA control tower for commercial, military, and general aviation use. In addition, the facility is favored by commercial and military flight test programs. Future plans include opportunities to build hangars at the airport as part of the SW Hangar Development area.
Airfield Airspace & Access
The FAA tower and radar facility controllers diligently control the airspace over and around the airport, safely and creatively ensuring all users can complete 100% of their missions. It is not uncommon for them to be controlling three independent traffic patterns simultaneously while approving a simulated rejected take-off or a UAV flight. Their professionalism shows in how they serve our mutual customers; they treat the student pilot and the senior flight test pilot with the same courtesy and attention to detail. Come see and hear for yourself!

Grant County International Airport offers a fully secured, 3,500-acre airfield. A background check and specific training is required before access credentials are issued. The airport has 24-hour support onsite.
Military Operations
The Port of Moses Lake welcomes military exercises throughout the year at the Grant County International Airport. The large airfield, surrounded by open terrain, make for excellent scenario-based training. Radar-controlled airspace abuts expansive Military Operations Areas (MOA) to the north for aircraft participating in multilateral mission simulations. It is not uncommon to see the USAF and US Navy sharing the traffic pattern, sometimes with an international visitor. The US Army drops in and sweep through the terminal and other port buildings made available for their use; the USMC has set up a forward refueling base in minutes to “defend” the coastline. We even see the Coast Guard on occasion!
