With its twin-engine and integrated inlet particle separator, it features exceptional reliability as well as high damage tolerance in combat conditions, and beats the Bell 412, Sikorsky S-76, Westland Lynx, and ALH Dhruv in 5 critical areas, namely: maximum useful weight,  maximum range, maximum power, maximum continuous power, and maximum tow (4).
