Rolls-Royce to supply MTU propulsion systems for Royal Navy frigates

The order comprises 40 engines and generator sets to be used for main propulsion and onboard power generation, the MTU Callosum propulsion control and monitoring system, and integrated logistics support (ILS).

Each frigate will be powered by four MTU 20V 8000 M71 engines, each delivering over 8,000-kW. Onboard power will be provided on each vessel by four MTU generator sets based on 16V 2000 M41B units, each delivering in excess of 900-kW.

The ILS for propulsion and onboard power systems will ensure efficient and cost-effective maintenance throughout their service life. The company expects the MTU Callosum propulsion control and monitoring system to be officially added to the supply contract shortly.

Rolls-Royce vice president marine & defense Knut Müller said “We’re proud Babcock International Group has opted for MTU propulsion and onboard power solutions on this highly significant project. MTU products now feature in almost all current and future projects of the Royal Navy.”

Rolls-Royce propulsion is featured across the Royal Navy’s surface and submarine fleets. The MTU Series 2000, 4000 and 8000 units will be used in most Royal Navy warships – in destroyers (Type 45), all frigate classes (Type 23, 26, 31) and submarines (Astute class).

The company will deliver the first shipset comprising four main propulsion engines and four generator sets to Babcock International in September 2021. In all, five newbuild general purpose frigates will be built by Babcock International Group at Babcock’s Rosyth yard in Dunfermline, Scotland. The first Type 31 frigate is scheduled to be in the water in 2023.
