The performance of the engine during the flight met the requirements of the first flight of a engine in the air vehicle. This 55 hp indigenous engine is expected to replace the present imported engine of Nishant. The critical core engine, including the special cylinder composite nickel-silicon carbide coating and special aluminium alloy castings, was designed and developed by NAL. VRDE developed engine peripherals such as the ignition and fuel systems and ADE developed flight testing. The reconnaissance UAV, which has completed its user trials with the Indian Army, is expected to be handed over to the army shortly.
