Rolls-Royce to showcase its mtu Series 199 engines at DSEI 2025, delivering proven power and performance for modern armoured fleets.

As land forces across NATO and allied nations accelerate fleet modernisation, the demand for scalable, battle-proven propulsion systems continues to grow.

At DSEI 2025, Rolls-Royce is presenting its mtu Series 199 engine family as a centrepiece of its land domain portfolio, contributing to the broader booth theme: “Providing the Power to Protect across land, sea and air”.

Specifically engineered for medium and heavy armoured vehicles, the Series 199 is a military off-the-shelf engine family offering a combination of high performance, modularity, and logistical efficiency. With more than 3,700 units deployed worldwide, it is one of the most operationally validated engines on the market today.

The engine range includes the 6V, 8V, and 10V configurations, delivering power outputs from 260kW to 1,100kW. This enables integration across a wide platform spectrum—from light tracked vehicles to full-weight main battle tanks. The engines feature best-in-class power-to-weight and power-to-volume ratios, which directly enhance vehicle agility, payload capacity, and system compactness.

The mtu Series 199 is fielded on a number of key international programs, including the Boxer armoured vehicle (Australia, Germany, the UK, and Ukraine), Poland’s Borsuk infantry fighting vehicle and OPAL III upgrade and the Ascod platform family (Austria, Spain, and the UK). Engine variants are tailored to each application, with programme-specific outputs and configurations.

Designed to meet stringent NATO operational standards, the engine is capable of operating from –46°C to +49°C. A pump-line-nozzle injection system supports poor fuel quality and multi-fuel operation (NATO F54, F63, F34/F35), enhancing logistics resilience in contested environments. Variable turbine control technology supports fast engine response, contributing to improved drivability and acceleration under load.

Time between overhaul exceeds 1,500 hours in tracked vehicle applications, verified through operational field data. Additionally, the system’s high technical readiness level reduces development risk and enables faster integration into both new and upgraded platforms.

Operational performance is reinforced by a comprehensive integrated logistics support framework. Rolls-Royce offers tailored lifecycle services, including on-site support, training, spare parts management and digital maintenance monitoring. This ensures platform availability and sustainment, even in remote or contested environments, while reducing the overall logistical footprint and cost of ownership.

While Rolls-Royce’ presence at DSEI (stand N7-210) spans all operational domains, the mtu Series 199 engine family stands as the land-focused embodiment of its mission: “A Force for progress—powering, protecting and connecting people everywhere”. With a proven track record, multi-national adoption, and engineering maturity, the Series 199 represents a leading propulsion solution for the future of armoured mobility.
