RR4500 ship service generator

The RR4500 harnesses proven industrial and aero gas turbine technology to deliver 4.5MW in a compact and efficient package.

It takes its pedigree from the same engine family that produced the highly successful industrial and marine 501. The combustor is similar to the aero parent design ensuring the RR4500 has an exceptionally low emissions signature.

At its core the RR4500 is a single shaft, high-pressure ratio gas turbine engine with a fourteen-stage axial compressor and boost compressor module for optimum reliability.

The unit has successfully completed evaluation powering the DDX Engineering Development Model (EDM) located at the US Naval Warfare Center in Philadelphia and was subsequently selected to power the first two US Navy DDG 1000 destroyers in 2007.


Rolls-Royce gas turbines are supported worldwide by the Rolls-Royce global service network, and a range of tailored maintenance packages are available.
