The In-Line was a prototype aircraft machine gun developed by AAI Corporation. The weapon was intended for a high rate of fire similar to the M134 Minigun, but with the accuracy of a fixed barrel machine gun. The In-Line machine gun concept worked but was not further developed.
Approximately three units were manufactured. An example of a six-barreled variant is on display at the U.S. Air Force Armament Museum.
