mi-28 is able to perform: nesterov's loop,immelman's overturn, sideways flight, flight back, sideways at a speed of up to 100 km/ h, turn with angular velocity up to 117 degrees / s, maximum angular velocity of rollmore than 100 deg / s. the mi-28 (nato reporting name "havoc") hasa conventional helicopter gunship layout with the pilot in the rear and gunner in front. it is armed with a 30-mm trainable cannonhoused in a turret under the nose. twin 150-round ammunition boxes are co-mountedto traverse, elevate and depress with the gun itself. a total of 300 rounds are carried.
the gun is identical to that of russian bmp-3infantry fighting vehicle and uses the same ammunition. this gunship can also carry two pods with80-mm unguided rockets and 16 anti-tank guided missiles. it is claimed that this helicopter can notbe defeated by a single short-range anti-aircraft missile. crew compartment is well armored. it withstands hits from 12.7-mm armor-piercingrounds and 20-mm he-frag rounds. the mi-28's cockpit is compatible with nightvision goggles; the pilot has a head-up display
and one crt on which tv imaging can be displayed. the primary sensor package comprises the opticalsights and laser rangefinder in an undernose turret. the crew are protected by energy-absorbingseats and an emergency escape system allows the crew to escape safely by parachute. a hatch in the port side, to the rear of thewing, gives access to the avionics compartment and a space large enough to accommodate twoor three passengers during a combat rescue. armament:the mi-28 is equipped with a chin-mounted 30 mm shipunov 2a42 autocannon.
the cannon is select fire, and has a dual-feed,which allows for a cyclic rate of fire between 200 rounds per minute to 550 rounds per minute. its effective range varies from 1,500 metersfor ground vehicles to 2,500 meters for air targets. rounds from high explosive incendiary to armour-piercingdiscarding sabot can be used. stated penetration for the 3ubr8 is 25 mmof rha at 1,500 meters. one common mi-28 armament are a pair of 8ataka missile racks along with 2 b-13l rocket pods, each able to carry 5 s-13 rockets. other rocket options include two b-8 rocketpods, each able to carry up to 20 s-8 rockets.
there are four variants of the ataka missilefor different tasks. the 9m120 tandem high explosive anti-tankwarhead variant is used against tanks fitted with explosive reactive armor, its penetrativeability is stated at 800 mm rolled homogeneous armour. the 9m120f thermobaric variant is used againstinfantry, buildings, bunkers, and caves. the 9m120o expanding rod warhead variant isused against other helicopters. all the variants have a range of 6 km. the 9m120m improved version has a longer range(8 km) and better penetration. all of the variants use saclos missile guidance.
the s-8 and s-13 rockets used by the mi-28are usually unguided. in the most common configuration, one canexpect 40 s-8 rockets or 10 s-13 rockets. both rockets have their variants, from heatwarheads to a thermobaric warhead. the s-8 has a shorter range and smaller warheadthan the s-13, but compensates with numbers. currently, the russian air force are upgradingtheir s-8 and s-13 rockets to laser guided missiles with the proposed ugroza ("menace")system. rockets upgraded under ugroza would receivedesignations s-8kor and s-13kor, respectively. in 1994 russian army funding allowed modificationof the first mi-28a prototype to mi-28n configuration. this introduced a mast-mounted mmw kinzhalv or arbalet radar, composite rotor blades,
forward-looking infra-red, an electronic flightinstrumentation system cockpit, improved armament options including igla-v air-to-air missilesand uprated tv3-117vk engines. the mi-28n made its first flight in april1997. production commenced in 2005. deliveries of the mi-28n attack helicoptersto the russian army began in 2006. however officially it was accepted to serviceonly in 2013. in 2005, a long-term contract was signed forthe supply of 67 mi-28n helicopters until 2013. in 2005, the chief of the russian generalstaff, army general yuri baluyevsky, stated
that the main combat helicopter would be themi-28n night hunter, while the ka-50 and ka-52 helicopters were needed for special forcesunits the mi-28ne night hunter is an export version. mi-28nm is the latest version. development of this helicopter was startedin 2008. it has a lot of differences comparing withthe mi-28n. this version is fully integrated into thedata transfer system by all channels, including video, target position and other data. also it is integrated with uavs.
mi-28ub is a combat trainer helicopter. it is based on the mi-28n. it can be used for pilot training, howeverthis helicopter retains full combat capability. mil also proposes a variant of the mi-28 forsupport of amphibious naval assaults.
