Ammunition canister and feed system

An aircraft comprising:

• an enclosure including a vertical mounting surface and a horizontal floor;
• a structure coupled to the enclosure in spaced relation to the vertical mounting surface;
• a gun including a receiver chamber and supported by the structure for a first rotation about a first axis, and for a second rotation about a second axis, the second axis perpendicular to the first axis;
• an ammunition canister including an outlet opening and coupled to the vertical mounting surface adjacent the horizontal floor;
• a feed chute configured to convey an ammunition belt from the outlet opening of the ammunition canister to the receiver chamber of the gun;
• wherein the outlet opening of the ammunition canister is positioned below the receiver chamber of the gun to reduce the bending of the feed chute therebetween and limit the drag on the ammunition belt traveling through the feed chute;
• a first end bracket secured to a first end of the canister;
• a second end bracket secured to a second end of the canister;
• a first end receiver configured to be secured to the vertical mounting surface and to receive the first end bracket;
• a second end receiver configured to be secured to the vertical mounting surface and to receive the second end bracket;
• a first pin configured to be slidably received by the first end bracket and the first end receiver for releasably coupling the first end bracket to the first end receiver;
• and
• a second right pin configured to be slidably received by the second end bracket and the second end receiver for releasably coupling the second end bracket to the second end receiver;
• a lid to at least partially cover an open upper end;
• wherein a first outlet opening is defined between the lid and the first end wall, and a second outlet opening is defined between the lid and the second end wall;
• wherein the feed chute extends above the first opening in a first orientation of the canister and extends above the second opening in a second orientation of the canister, the second orientation being rotated 180 degrees about a vertical axis.
