The Rolls-Royce WR-21 is an aeroderivative marine gas turbine, the first to combine a compressor intercooler with an exhaust heat recuperator, which the maker says cuts fuel burn by about 30 percent across a typical ship operating profile. It has a rated power of 25.2 MW, a twin-spool gas generator and a five-stage free power turbine. Its design draws heavily on the RB211 and Trent families. Development began under a US Navy contract placed with Westinghouse in December 1991 and was later led by Northrop Grumman with Rolls-Royce and the French DCN, and it propels the Royal Navy Type 45 destroyers. The intercooler proved unable to cope with seawater above 30 degrees Celsius, which caused failures on HMS Daring in 2010 and 2012.
