Mil Mi-28 "Havoc"
Info:
The Mil Mi-28 (NATO reporting name "Havoc" ) is a Russian all-weather day-night military tandem two-seat anti-armour attack helicopter. It is a dedicated attack helicopter with no intended secondary transport capability, better optimized than the Mil Mi-24 for the anti-tank role. It carries a single gun in an undernose barbette, plus external loads carried on pylons beneath stub wings.
Development:
Yet another variant, the Mi-28N, was unveiled in 1995, the N designation meaning "night". The prototype ( flew on November 14, 1996. The most significant feature is a radar in a round cover above the main rotor, similar to that of the American AH-64D Longbow Apache. It also has improved Tor vision and aiming device under the nose, including a TV camera and FLIR. Due to funding problems, development was interrupted. A second prototype with an improved rotor design was unveiled in March 2004 at Rosvertol.
Mil Mi-28 gun mounting.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, 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.
