The SSZ (Sea Scout Zero) non-rigid airships or "blimps" were developed in United Kingdom during World War I from the earlier SS ("Sea Scout") class. The main role of these craft was to escort convoys and scout or search for German U-Boats. ==Design and development== The SSZ was built at the Royal Naval Air Service (RNAS) airship station at Capel-le-Ferne〔(''Twenty-One Years of Airship Progress.'' ) flightglobal.com. Retrieved on 28 March 2009.〕 near Folkestone to the design of three officers that were serving there〔Whale (2008), p.60.〕 as a successor to the SS class.〔Castle (2009) p23〕 Similar to other SS class types, the SSZs had an envelope of capacity containing two ballonets of each;〔(SSZ data. ) Airship Heritage Trust. Retrieved on 18 March 2009.〕 and like the SSPs, the fuel was contained in aluminium tanks slung on the axis of the envelope.〔Whale (2008), p.61.〕 The design of the car was a departure from that of other SS types. It was streamlined, boat-shaped and watertight, was floored from end-to-end, and was enclosed with sides of fabric-covered 8-ply wood〔 or aluminium. The car was comfortable and accommodated a 3-man crew – the forward position being occupied by the wireless operator/gunner with the pilot seated amidships, and the engineer was stationed at the rear.〔 A single water-cooled Rolls-Royce Hawk engine was mounted on bearers above the level of the rear of the car, and drove a diameter four-bladed propeller in pusher configuration.〔 The SSZ design was judged superior to the SSP, which had been developed at RNAS Kingsnorth at the same time, and so the SSP was cancelled.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SSZ class airship」の詳細全文を読む スポンサード リンク
