The MTU 8v 199 TS21 engines are proven in military applications. With a power output of 600kw, the engines allow for enhanced operational mobility and agility, and a higher electrical load. The Boxers for the British Army will be the first versions of the vehicle equipped with this engine variant, delivering 70 KW more power than the MTU engines in previous versions of the Boxer.
523 units of the engine will be produced in Rolls Royce’s facility in East Grinstead, West Sussex, for the UK MOD’s Mechanised Infantry Vehicle (MIV) programme.
For the fulfilment of the contract with WFEL, the Rolls Royce engines will be delivered directly to Huddersfield-based David Brown Santasalo, another key UK partner in WFEL’s Boxer programme, who will integrate the engines into the complete Boxer Powerpack Assemblies, prior to delivery to WFEL. First delivery of the engines will take place later this year.
For RBSL, assembly and testing of the Boxer Powerpack (transmission, engine and cooling systems) will take place at its world-class manufacturing site in Telford.
The engines will then be integrated into Boxer vehicles as part of RBSL and WFEL’s vehicle production plans at their respective UK facilities in Telford and Stockport.
The Boxer programme aims to develop a resilient UK supply chain for Boxer. As such, WFEL and RBSL are part of a Boxer Joint Procurement Team, which has engaged suppliers in England, Wales, Scotland and Northern Ireland. Rolls Royce is the latest in a series of suppliers confirmed for the programme.
In April 2022, the British Army announced it had ordered an additional 100 Boxer armoured vehicles, bringing the total number on order to 623.
