Снаряд 30 мм (абсолютно новый, "с нуля") у буржуев ориентировочно стоит $100. 23 мм стоит около $70.

У меня нет данных о стоимости гильз от 30-мм пушек. Но она очевидно не превышает показателей 50% от общей стоимости

the M61A2, along with the F-22's superior maneuverability, gives the pilot one more option.

The General Dynamics Armament System-developed Linear Linkless Ammunition Handling System (LLAHS) consists of a 480 round ammunition storage container with drive train and integral access (reload) unit, an ammunition conveyor assembly, a hydraulic drive unit, a rounds limiter, and a last round switch. There are no links between rounds (hence the term "linkless") an innovation that eliminates completely any potential jamming of the gun breech. Ammunition is transported from the container to the gun breech by a direct extension of the carrier chain, which also carries the empty cartridges back to the ammunition storage container to form a closed loop system. The LLAHS is loaded manually from the ground. The rounds limiter is an electromechanical device that is preset to limit the number of rounds that can be fired on a training flight. The last round switch shuts down the gun when it senses the empty casing of the first round fired. The LLAHS is located very near to the aircraft's center of gravity, so by retaining the casings, even after all the rounds are fired, there is no change forward or aft to the aircraft's center of gravity. Also, by not ejecting the casings, a potentially serious foreign object debris (FOD) problem (i.e. ingesting casings into the engines) simply does not exist.
