The "Home of the Fighter Pilot," Nellis Air Force Base is home to the U.S. Air Force Warfare Center, the largest and most demanding advanced air combat training mission in the world. Nellis is the home of Testing, Tactics, and Advanced Training for the Combat Air Force. This mission is supported through management of 3 military bases, a 2.9-million-acre Range Complex and more than 12,000 square miles of Southern Nevada airspace. Training is conducted in conjunction with air and ground units of the Army, Navy, Marine Corps and air forces from our allied nations. The crews do not come to learn how to fly, but instead how to be the best combat aviators in the world.
