3) ii. Mi-28NM
An updated variant of the Mi-28N came to fruition in 2009. The helicopter’s nose hull has been redesigned due to the removal of its nose antenna, a new H025 radar station for all-around visibility, more powerful VK-2500P engines with FADEC instead of the previous Klimov TV3-117VMA engines, and improved rotor blades, resulting in a 13 percent increase in maximum speed and a 10% increase in cruise speed. Aside from that, it has a new “Izdeliye 296” onboard radio-electronic data processing system and an updated fire-control system. It can be armed with the 9M123 Khrizantema-V and 9M127-1 Ataka-VM anti-tank missiles.

Mil Mi-40 was a planned utility version of the Mi-28 that was first proposed in 1983, publicized in 1992, and first flown at the Moscow Airshow in 1993. It was designed to replace the Mil Mi-24 and Mi-8 assault helicopters in the “Aerial Infantry Fighting Vehicle” category. It has two 1,863 kW Klimov TV3-117 turboshaft engines, a four-blade main rotor, four-blade Delta H tail rotor (both Mi-28), and retractable tricycle-type landing gear. It weighs around 11–12,000 kg and has a 3300 m ceiling, a maximum speed of 314 km/h, and a cruise speed of 260 km/h.
