The Alcock A.1 (also known as the "Scout" and "Sopwith Mouse") was born at Royal Naval Air Service Moudros by Flight Lieutenant John Alcock during World War 1 (1914-1918). The fighter was of largely conventional biplane design, seating a sole crewmember and powered by a single engine. To expedite development, sections of existing fighter types (mainly from the Sopwith product line) were used to bring the machine together. In the end only a sole flyable prototype was completed and a crash in early-1918 ended its time in the skies, its potential as an in-service wartime military fighter for Britain never realized.
Lt Alcock began work on the new "fighting scout" during mid-1917 as the World War continued to rage on with no signs of ending. The makeup of the biplane involved the forward fuselage and lower wing sections of the Sopwith Triplane coupled with the upper wing assemblies of the Sopwith Pup biplane (parallel support struts being featured). To this was added an all-new tail section including original rear fuselage. The tailplane and elevator control surfaces of the Sopwith Camel biplane fighter rounded out the mix of aircraft parts used to create the new biplane. Armament was a single 7.7mm Vickers Machine Gun and power was from a Clerget 9Z 9-cylinder rotary engine of 110 horsepower (driving a two-bladed propeller at the nose). The undercarriage was fixed and wheeled at the main members (these located under the forward fuselage). The pilot's position was behind and under the upper wing element, seated in an open-air cockpit.
Dimensions of the Alcock A.1 included a length of 5.8 meters, a wingspan of 7.4 meters and a height of 2.3 meters.
As the aircraft was made up of a collection of Sopwith aircraft-related components it came to be known as the "Sopwith Mouse" by its circle of creators.

(Showcased structural values pertain to the Alcock A.1 production variant)
biplane / over-under / straight
Design utilizes a dual-plane wing arrangement in which one mainplane member is seated above the other; biplanes enhance agility at the expense of added drag.
Dual mainplane configuration seating the members in an over-under fashion and poisitoned at different points along the fuselage.
The planform involves use of basic, straight mainplane members.
