Rolls-Royce to provide MTU diesel gensets for the UK Navy’s Type 26 frigates


Type 26

BAE Systems has sub-contracted Rolls-Royce to manufacture MTU diesel generators for the first three next-generation Type 26 Global Combat Ships (GCS) for the UK Royal Navy.

Under the contract, Rolls Royce will supply the core components of the frigate's combined propulsion system that include four MTU diesel gensets with 20V 4,000 M53B engines, each delivering 3,015kW of mechanical power, and one Rolls-Royce MT30 gas turbine.

Each Type 26 anti-submarine warfare vessels will be fitted with four MTU diesel gensets.

“The MTU propulsion system meets the requirements of the IMO III emissions directive.”

Based on 20-cylinder MTU Series 4,000 engines, the MTU diesel gensets are said to offer a low-emission solution to the ships' electrical supply and slow speed propulsion.

The MTU propulsion system meets the requirements of the IMO III emissions directive.

The engines are said to be equipped with an exhaust after-treatment system, which uses a Selective Catalytic Reduction unit to neutralise nitrogen oxide emissions.

The generator sets are placed on specialist mounts and surrounded by an acoustic enclosure, to ensure the operation of the propulsion system at low noise levels.

MTU Governmental Business head Knut Müller said: "The Type 26 Global Combat Ship is the first newly-designed Royal Navy surface vessel to be equipped with MTU engines and the fact that we are involved in such a leading-edge project fills us with great pride."

In March this year, the UK Ministry of Defence announced a further £472m investment for the Type 26 GCS programme.

The UK Government intends to buy eight of the advanced anti-submarine warfare ships.

Set to replace the Type 23 frigates, the Type 26 vessels will be capable of undertaking a wide range of roles from high-intensity warfare to humanitarian assistance, either operating independently or as part of a task group.
