 | | Further development resulted in some experimental, electrically driven,.60 caliber machine guns with 6 barrels, and, in 1956, the 6-barreled 20mm T171 gun was officially adopted as the M61 aircraft gun. |
 | | This achievement is possible due to the fact that gun has multiple barrels, and the rate of fire per one barrel is about 1 000 rounds per minute or even less, allowing them to not to overheat. |
 | | Another drawback of the Gatling-type guns, which is essential for aerial combat, is that the gun requires some time to get on to the full speed (rate of fire) after the trigger is pressed. |
