The Mil Mi-28 (NATO reporting name "Havoc") is a Russian all-weather, day-night, military tandem, two-seat anti-armor attack helicopter. It is a dedicated attack helicopter with no intended secondary transport capability, better optimized than the Mil Mi-24/25/35 gunship for the role. While the Mi-28 is not intended for use as a transport, it does have a small passenger compartment capable of carrying three people. The planned purpose of this is to enable the rescue of downed helicopter crews. The Mi-28 helicopter is equipped with a turreted 2A42 30mm cannon, stabilised in two axes, plus external loads carried on pylons beneath stub wings (aams, atgws, rocketpods, gunpods, submunition dispensers).
Mi-28N is a more heavily armored night attack variant. The Night Havoc helicopter retains most of the structural design of the Mi-28. The main difference is the installation of an integrated electronic combat system. Other modifications include: new main gearbox for transmitting higher power to the rotor; new all plastics 30mm shell resistant high-efficiency blades with swept-shaped tips; and an engine fuel injection control system. The main sensors of the integrated electronic combat system are the microwave radar antenna, mounted above the rotor head, and a forward-looking infrared (FLIR) system. The system displays the helicopter location on a moving map indicator, and flight, systems and target information on liquid crystal displays. The crew are equipped with night-vision goggles.
The dual-control Mi-28NE is a variant of the helicopter that enables both personnel onboard to pilot the aircraft.
