Apparatus for aerial refuelling comprises a frame 2 for attaching around an aperture in an aircraft floor 3, and a movable hose drum housing 4 pivotally mounted on the frame. The hose drum 12 may be stowed within the aircraft, and moved into the aperture, for example using screw jacks 20, for deployment of the drogue 40. Since the hose is deployed from a position nearer the outside of the aircraft, the hose does not scrape the edge of the aperture even when lying at a shallow angle to the aircraft.
