The cousin to the Mi-28NM, the Ka-52 is another advanced anti-tank helicopter in the Russian arsenal. With the distinctive coaxial rotor system, the Ka-52 has even better maneuverability than the 28NM, without sacrificing payload. In fact, the Alligator will likely phase out the 28NM in time as it carries more missiles. No surprise, it also houses the same autocannon as the 28NM.
