Rolls-Royce is to supply complete MTU propulsion systems for five new Type 31 general-purpose frigates for the UK Royal Navy.

Each new 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.

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.
