After the Gatling gun was replaced in service by newer recoil or gas-operated weapons, the approach of using multiple externally powered rotating barrels fell into disuse for many decades. However, some examples were developed during the interwar years, but only existed as prototypes or were rarely used. The concept resurfaced after World War II with the development of the Minigun and the M61 Vulcan. Other versions of the Gatling gun were built from the late 20th century to the present, the largest of these being the 30mm GAU-8 Avenger autocannon as used on the Fairchild Republic A-10 Thunderbolt II.
