The Mil Mi-28 ('Havoc') is a Russian all-weather day-night military tandem two-seat anti-armour attack helicopter. Mil Mi-28 is a dedicated attack helicopter with no intended secondary transport capability, better optimized than the Mil Mi-24 for the anti-tank role. Mil Mi-28 carries a single gun in an under nose barbette, plus external loads carried on pylons beneath stub wings. The Mi-28 has two heavily armored cockpits, a nose full with electronic equipments, and a narrow-X tail rotor. Its engines are two 2,200 hp Isotov TV-3-117VM (t/n 014) gas turbines. The X-type tail rotor (55 deg) has reduced noise characteristics. 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.Specifications of Mil Mi-28

Variants of Mil Mi-28
- Mi-28A - Original production anti-tank helicopter. Development done in 1998, first flight in 2003.
- Mi-28N/MMW Havoc - All weather day-and-night combat helicopter. It is equipped with a top-mounted millimeter wave radar station, IR-TV, and laser ranger. Serial Mi-28N will have two TV3-117V MA-SB3 engines (2500 hp each), made by the Ukrainian Motor-Sich. Max take off weight of 11500 kg, max payload weight of 2350 kg.
- Mi-28N has been entered service under the name of "Night Hunter" (Russian: Ночной охотник). A squadron of Mi-28N from Torzhok town has taken part in the joint army exercise in Belorussia in June 2006.
- Mi-28D - simplified daylight operation version. Similar to Mi-28N, but without top-mounted radar and TV-channel in sight. Unit price USD 15M..17M.
- Mi-28NAe - export version offered to North Korea.
- Mi-40 - armed transport version.
A changed military situation after the Cold War made specialized anti-tank helicopters, like Ka-50, less useful. On the other hand, its all-weather two-seater variant Ka-52 had worse performance due to increased weight. The advantages of the Mi-28N, like all-weather action ability, lower cost, and similarity to the Mi-24, have become important. In 2003, a chief of Russian Air Forces stated that Mi-28N will become the standard Russian attack helicopter.
The first serial Mi-28N was passed to the Army. The aircraft joined the two pre-serial machines which were used for army trials. The aircraft entered service in 2006, along with the similar Ka-50/Ka-52. Up to 10 helicopters will be purchased in 2006 of total 300 to be purchased to 2015.
There is an export variant, known as Mi-28NE, and a simpler day-helicopter variant, the Mi-28D, based on the Mi-28N design, but lacking radar and FLIR.
