The basic model of what is arguably one of the most successful fighter aircraft in history. Following lessons from the performance of the F-4 in Vietnam against the MiG-21, as well as a fear that the MiG-25 was a highly maneuverable dogfighter (which would be dispelled in 1976, after development, when Viktor Belenko defected a MiG-25 to the West via Japan), the F-15 was designed as a dedicated fighter, to the point where there was not a "pound for air to ground" in the original design. As a result, performance and maneuverability were emphasized. This made it a very competent dogfighter and interceptor. Improvements over the F-4 in this regard include an integral gun (The F-4's gun was retrofitted), lighter weight, more powerful engines, and lower wing loading. Despite the original intent as a pure air superiority fighter, it would prove versatile enough to be employed as one. It is now the fighter plane with the longest production time of 47 years and counting. This example is a Paternian Air Force model in a substitute standard gray and white camouflage than the two-tone gray camouflage.
