Linkless ammunition loading installation comprising: - a traversing portion configured to be rotatably mounted and supported on a stationary support structure, so as to rotate about a traversing axis, - an elevating portion rotatably supported by said traversing portion about an elevating axis perpendicular to the traversing axis, - a firearm assembly supported by the elevating portion and comprising a barrel configured to fire ammunitions through itself, - a magazine carried by said traversing portion and configured to contain a plurality of linkless ammunitions to be fed to said barrel, - a feeding assembly configured to transfer the linkless ammunitions from said magazine to said barrel for firing said linkless ammunitions, said feeding assembly being carried by said elevating portion, and - a transfer device configured to transfer said linkless ammunitions from said magazine to said feeding assembly; wherein said magazine is separate and distinct from said elevating portion, and said feeding assembly is separate and distinct from said traversing portion; and wherein said transfer device is mounted on said traversing portion and comprises a star element rotatably supported about a rotation axis; wherein said feeding assembly comprises a conveying guide mounted on said elevating portion and defining a path for transporting said linkless ammunitions from said transfer device towards said barrel; said installation being characterized in that said rotation axis is parallel to said elevation axis; in that the centre of ammunition to be picked up by said star element lies on said elevating axis during a part of the rotation path of said star element; in that said rotation axis is spaced apart from said elevating axis along the direction of said traversing axis; in that said conveying guide is provided as a rigid conduit; in that said conveying guide has an inlet which is located at said elevating axis; and in that said inlet is crossed transversally by said elevating axis. - a traversing portion configured to be rotatably mounted and supported on a stationary support structure, so as to rotate about a traversing axis, - an elevating portion rotatably supported by said traversing portion about an elevating axis perpendicular to the traversing axis, - a firearm assembly supported by the elevating portion and comprising a barrel configured to fire ammunitions through itself, - a magazine carried by said traversing portion and configured to contain a plurality of linkless ammunitions to be fed to said barrel, - a feeding assembly configured to transfer the linkless ammunitions from said magazine to said barrel for firing said linkless ammunitions, said feeding assembly being carried by said elevating portion, and - a transfer device configured to transfer said linkless ammunitions from said magazine to said feeding assembly;
