Eurocopter AS 532

The Eurocopter AS 532 Cougar is a twin-engined, medium-weight, multipurpose helicopter. The AS 532 is a further development and upgrade of the Aérospatiale Puma in its militarized form. (Its civilian counterpart is the Eurocopter Super Puma.) The AS 532 has been further developed as the Eurocopter EC 725.

Development

The AS 332 Super Puma, designed as a growth version to replace the SA 330 Puma, first flew in September 1977. It was fitted with two 1330kW Turbomeca Makila 1A1 turboshaft engines, composite rotor blades, improved landing gear and a modified tailfin.

In 1990 all military Super Puma designations were changed from AS 332 to AS 532 Cougar to distinguish between the civil and military variants of the helicopter.

Canada had considered purchasing the Cougar to replace their CH-113 Labrador, but opted in the end to purchase the CH-149 Cormorant.

Variants

The current variants of the Cougar are:

AS 532 UL/AL

The AS 532 UL/AL is the long version of the Cougar family and is powered by two Turbomeca Makila 1A1 turboshaft engines. It carries a crew of 2 and up to 29 troops or 6 injured passengers on stretchers plus 10 others. As with the other versions of the Cougar, the AS 532 UL/AL can lift 4.5 tons by means of a sling.

The Horizon battlefield ground surveillance system can be installed on the AS 532 UL (utility version).

The AS 532 AL (armed version) can also be fitted with a variety of weapons, including pod-mounted 20 mm cannons, 68 mm rocket-launchers and side-mounted machine-guns.
