An assembly having an aircraft door and auxiliary equipment. The aircraft door and the auxiliary equipment are connected by a flexible deformable bellows having creases. The door comprises a passing through hole and a support joinable to the first end of the bellows. The auxiliary equipment comprises a support joinable to the second end of the bellows and a projecting part. The projecting part is configured to have elevation movement and/or azimuth movement, and the projecting part crosses the interior of the bellows and the hole of the door and protrudes out of the door. At both ends of the bellows a clamp joins and tightens each end of the bellows with the corresponding support. There is a fixed joint between the first end of the bellows and the door and a movable joint between the second end of the bellows and the auxiliary equipment.

A ball turret includes a turret shell having a rear portion and a front portion. The rear portion and the front portion are assembled to form the turret shell. The shell includes a block assembly configured to mount to a mounting element of a weapon system, and a yoke carriage assembly configured to receive and mount to the block assembly. A number of guide rods within the turret shell are configured to mount the yoke carriage assembly thereto and to provide a recoil shock absorber in response to a discharge of the weapon system. The yoke carriage assembly is releasably mounted to the block assembly.

The installation space dimensions of a weapon system in the tower are complied with, and a loading space diameter of a caliber-larger weapon barrel is approximately maintained in relation to the smaller caliber. The required larger loading space volume for the caliber increase is predominantly achieved by an extension of the loading space of the caliber-larger weapon barrel relative to a loading space of the caliber-smaller weapon barrel itself. Since the loading space diameter of a larger caliber remains virtually unchanged, the outer dimensions of the caliber-larger weapon barrel also remain virtually unchanged compared to the outer dimensions of the caliber-smaller weapon barrel in the region of the loading part.
