Bharat Earth Movers Limited (BEML) has sent the first 1500 horsepower (HP) DATRAN engine to the United Kingdom for mechanical and combustion testing as part of the next phase of the engine’s development. The testing will include endurance trials of 400, 600, and 1500 hours.

The DATRAN 1500HP engine is a key component for the Arjun Main Battle Tank (MBT) program. Supply issues with engines from German manufacturer MTU, which ceased production of the engines used in older Arjun MkI MBTs, prompted the development of an indigenous alternative. The DATRAN engine is intended to power both the Arjun Mk-1 and Mk-2 variants as well as the Future Ready Combat Vehicle (FRCV).

BEML successfully conducted the maiden test-firing of the first indigenously manufactured DATRAN 1500HP tank engine at its Mysuru facility on March 20, 2024. The engine development project, which started in August 2020, is expected to be completed by mid-2025. The initial production phase focused on technology stabilization, while the current phase involves trials at DRDO’s Combat Vehicles Research and Development Establishment (CVRDE) and integration into vehicles for user testing.

According to BEML, the DATRAN engine is designed to improve the operational mobility and endurance of Arjun tanks across different terrains, including deserts and high altitudes. The engine incorporates features such as electronic control with CRDi fuel injection and self-cleaning air filters, and is capable of operating in sub-zero temperatures.

The DATRAN program is also serving as a platform for future development. DRDO is exploring the creation of modular variants with higher power outputs, potentially up to 1800 HP, and hybrid propulsion systems combining internal combustion and electric power for potential future combat vehicles.

BEML is an Indian manufacturer of heavy equipment used in sectors such as defence, railways, construction, and mining. The company collaborates with the Defence Research and Development Organisation (DRDO) on several defence projects, including the development of engines and other components for combat vehicles.
