The Saunders A.3 Valkyrie was a large three-engined biplane flying boat with a wooden hull built to an Air Ministry specification. It was not found suitable for production and helped to confirm a preference for metal-hulled flying boats. ==Development== The Saunders A.3 Valkyrie was built in response to Air Ministry specification 22/24 for a large general duty and patrol flying boat, Saunders receiving an order for a single prototype for trials in February 1925. It was a three-engined biplane with a two step monocoque hull, circular apart from the shallow, curved planing bottom. The fuselage had no internal bulkheads and was deliberately designed to be flexible so as to absorb the shocks of landing, though there was a rigid section under the wings. As with Saunders' other wooden aircraft, Valkyrie's hull was covered with Consuta sewn stress-bearing plywood. It accommodated a crew of five. There was a pair of open tandem cockpits with dual flying controls well forward of the wing leading edge. Below this, aft and in the hull were the navigation and radio operator's position, and further aft, behind the trailing edge there were two gunners' positions, roughly in tandem but offset port and starboard, each fitted with machine guns on Scarff rings. The gunner's cockpit in the nose was similarly equipped. There were bunks and living space for all five crew in the rigid part of the hull. The fin was large and angular, carrying the braced rectangular tailplane with unbalanced elevators above the top of the hull. The fin also carried a large and prominently balanced rudder with a rudder servo surface on outriggers.〔Flight, 5 July 1928〕 The wings were of equal span and almost no stagger, with slight sweep on the section outboard of the engines. These outboard sections each had two sets of simple vertical interplane struts, carried balanced ailerons on upper and lower planes and a V-bottomed stabilising float mounted clear of the lower wing. The wings were wooden structures with canvas covering, as was the upper centre section. The lower wing centre section was Consuta covered, mounted on a low pylon on the hull and braced to it with large N shaped struts.〔 The centre sections were joined by three sets of steel V-form struts,〔Flight, 21 July 1927〕 from which the Valkyrie's three 680 hp (505 kW) Rolls-Royce Condor water-cooled engines were mounted midway between the wings.〔
