Combat flight simulators are video games (similar to flight simulator or amateur flight simulation software) used to simulate military aircraft and their operations. These video games are distinct from dedicated flight simulators used for military flight training which consist of realistic physical recreations of the actual aircraft cockpit.

Combat Flight Simulator WWII Europe Series (CFS1) is the first version of combat flight simulators from Microsoft, released November 1, 1998. CFS1 is set in the European Theater of World War II.
