This Eagle V aero engine was made in 1916 by Rolls Royce Ltd. It would have powered the Fairey Campania single-engine sea plane. The Eagle V was an early version of the successful family of engines which powered a variety of types, from long-range flying boats such as the Felixtowe F3.3 F5 and heavy bombers such as the Handley Page HP 0/400 and V/1500, to single engine civil transport aircraft, notably the De Havilland DH-16.

This 12-cylinder, 322-horsepower engine has the individual cylinders arranged in a Vee configuration, with six cylinders on either bank. Its normal revolutions per minute was 1800, with a maximum permissible of 1900. Its capacity was 20.32 litres.

Irrespective of series number, the Eagle was a 12-cylinder, water-cooled 60 degree Vee engine. It was first run in 1915 and the last variant was the Eagle XVI in 1925. The Eagle set the standard for later Rolls Royce Vee 12 engines, such as the Condor and Falcon, with each cylinder forming a separate unit. The Eagle VIII variant was the most widely used and most famous. The Vickers Vimy that made the first non-stop crossing of the Atlantic by air on 14 and 15 June was powered by two Eagle VIIIs.
