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 gunship for the role. It carries a single gun in an undernose barbette, plus external loads carried on pylons beneath stub wings.
First flown in November 1982, and designed to fulfil the same role as the American AH-64 Apache which it generally resembles, the agile Mi-28 'Havoc' military helicopter was scheduled to enter full service with the CIS forces in 1992, but lost out to the Kamov Ka-50. The three prototypes had a conventional three-bladed tail rotor but this has since been replaced by a 'delta 3' x-configured rotor comprising two independent two-bladed propellers mounted on the same shaft.
