|Role||Submarine-launched reconnaissance flying boat|
Design and development[edit | edit source]
Due to the need to be stored and launched from a submarine the W.20 was a small single-seat biplane flying boat that was designed to be assembled and dismantled quickly. It had a slender hull on which was mounted a biplane wing and a conventional braced tailplane. It had an Oberursel rotary engine mounted on struts between the wings driving a pusher propeller. The pilot had an open cockpit just forward of the lower wing. Because of the slender hull stabilising floats were fitted below and at the end of the lower wings. The submarine intended to carry the W.20 was not built and only three W.20s were built.
