The Ka-52 Alligator is a two-seat Russian attack helicopter powered by two VK-2500 turbo-shaft engines (2,400hp each). The powerful engines allows the helicopter to fly at altitudes over 5,000m (16,404ft). It can take-off and land in hot and high conditions as well as in extremely cold and icy conditions.

NH90

The NH90 is a medium lift, multi-role military helicopter. It was developed in response to NATO requirements for a battlefield helicopter which would also be capable of being operated in naval environments. The helicopter’s impressive cruise speed of 300km/h makes it one of the fastest helicopters in the world.

The NH90

The NH90 is a twin-engine military helicopter developed in two versions – tactical troop transport (TTH) and NATO Frigate Helicopter (NFH). The NH90 is well suited for operations in the most demanding conditions over land and sea, day and night. The high-performance engine enables the helicopter to reach a maximum altitude of 3,200m (10,500ft) at a rate of climb of 2,200ft/min.

AgustaWestland AW139

The AW139 is a medium sized, new generation twin-turbine military helicopter developed and produced principally by AgustaWestland. At a maximum speed of 306km/h, the AW139 comes 5th amongst world’s fastest helicopters. The AW139 can transport up to 10 fully equipped soldiers or 15 passengers at very high speeds.

The AW139

Since 2003, the AW139 has become one of AgustaWestland’s most influential products; it has been subsequently developed into two enlarged medium-lift helicopters, the military-orientated AW149 and the AW189 for the civil market.

AW101 (EH101) Merlin

The AW101 Merlin is a flexible medium-lift helicopter which can fly at a maximum speed of 309km/h making it one of the fastest helicopters in the world. It is produced by AgustaWestland for military and civilian applications.

The AW101 Merlin 

Powered by three Rolls-Royce/Turbomeca RTM322 turboshaft engines that provide the helicopter high lifting capacity and top speed. Each engine develops a power of 2,270shp and ensures operations at a maximum altitude of 15,000ft.

Mi-35M

With a maximum speed of 310km/h, Mi-35M comes at No.3 amongst world’s 10 Fastest Helicopters. This multirole attack helicopter is a comprehensive modernisation of the Mi-24V. It is produced by Mil Moscow Helicopter Plant and has been operated since 1972 by the Soviet Air Force and its successors, along with more than 30 other nations.

The Mi-35M

The Mi-35M entered serial production phase in 2005 at Rostvertol plant. It is powered by two engines having 2,200hp each. The operational altitude and normal range of the helicopter are 5,400m (17,716ft) and 460km respectively.

CH-47 Chinook

The CH-47F Chinook is powered by two Honeywell T55-GA-714A engines generating 4,777shp (3,529kW) of power each enable the CH-47F fly at altitudes up to 20,000ft (6,096m) while carrying a load of 10,886kg.
