HMS Champion (1915)
HMS ''Champion'' was a light cruiser of the Royal Navy that saw service during World War I. She was part of the ''Calliope'' group of the C class.
==Construction==
Eight light cruisers were ordered for the Royal Navy in the 1913 budget. The six ships of the ''Caroline'' class used conventional direct-drive turbine engines but two, ''Champion'' and , had experimental engine designs using geared reduction to match optimum working speeds of turbines and propellers. This followed experimental designs ordered in 1911 using geared high-pressure turbines for the destroyers and and in 1912 using gearing for both high-pressure and low-pressure turbines in the destroyers and . ''Champion'' and ''Calliope'' tested different designs.〔Brown p.24-25〕
Built by Hawthorn Leslie and Company at Tyneside, England, ''Champion'' was laid down on 9 March 1914, launched on 29 May 1915, and completed in December 1915.〔Gardiner, Robert, ed., ''Conway's All the World's Fighting Ships, 1906-1921'', Annapolis, Maryland: Naval Institute Press, 1985, ISBN 0-87021-907-3, , , p. 57, ((preview of 2006 reprint )).〕
''Champion'' had two propeller shafts, the port one being driven from the sternmost engine room and the starboard one from forward. Gearing increased overall engine efficiency, allowing a reduction in boiler and turbine size for a given force provided by the propellers, so the initial design reduced the boiler room size and dropped the nominal developed power from 40,000 shaft horsepower (shp) (29.8 megawatts/MW) to 37,500 shp (28.0 MW). However, during construction modifications were made to again increase boiler capacity and add cruising turbines which returned to the nominal power output of the ''Caroline'' class ungeared ships. Maximum propeller speed was a nominal 340 revolutions per minute. Trials comparing ''Champion'' to ''Caroline'' showed that at actual developed power of 41,000 shp (30.6 MW) in both ships, ''Champion'' achieved a speed of 29.5 knots using 470 tons of fuel per day, while ''Caroline'' achieved 29 knots using 550 tons of fuel per day. The ship could achieve 28 knots operating at the lower power of 31,000 shp (23.1 MW).〔
