As the only Black Hawk in Ukrainian service, N60FW is used to support special forces. The DIU reports that its performance far exceeds the Mi-8 and Mi-24. "The helicopter impresses with its reliability, ease of operation and combat survivability," the Black Hawk's flight engineer said in a DIU news statement. The helicopter's pilot, who has experience on the Mi-8 and Mi-24, noted that he was able to fly the Black Hawk on the first day after just a few hours in the cockpit.
