Rolls-Royce is to supply complete MTU propulsion systems for the five new Type 31 general-purpose frigates contracted for the Royal Navy. In total, the order comprises of 40 engines and generator sets to be used for main propulsion and on-board power generation with the MTU Callosum propulsion control and monitoring system in addition to Integrated Logistics Support (ILS). Each new frigate will be powered by four MTU 20V 8000 M71 engines, delivering over 8,000 kW, while on-board 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. In September 2021, Rolls-Royce will deliver the first shipset comprising four main propulsion engines and four generator sets to prime contractor Babcock International Group. ILS for propulsion and onboard power systems will ensure efficient and cost-effective maintenance throughout their entire service life while it is expected that the MTU Callosum propulsion control and monitoring system will be officially added to the supply contract very shortly.

Proven partner

Sean Donaldson, Managing Director for Energy & Marine at Babcock International, said: “We’re delighted to welcome Rolls-Royce with its MTU solutions as a supplier to our Type 31 Programme. Its engines and on-board generator sets are already proving their mettle in numerous comparable vessels worldwide.”

Knut Müller, Vice President Marine & Defense at Rolls-Royce business unit Power Systems, said: “We’re very proud of the fact that Babcock International Group has opted for MTU propulsion and on-board power solutions on this highly significant project. MTU products now feature in almost all current and future projects of the Royal Navy. That is impressive proof of the trust our British partners place in us and of the reliability and flexibility of our products.”

The Royal Navy relies on Rolls-Royce propulsion solutions across its surface and submarine fleets. MTU Series 2000, 4000 and 8000 units will feature in future in most Royal Navy warships – in destroyers (Type 45), all frigate classes (Type 23, 26, 31) and submarines (ASTUTE class).
