AS532 Cougar

The Eurocopter AS532 Cougar is a twin-engined, medium-weight, multipurpose helicopter developed by France.  The AS532 is a development and upgrade of the Aérospatiale Puma in its militarized form.  (Its civilian counterpart is the Eurocopter AS332 Super Puma.) The AS532 has been further developed as the Eurocopter EC725. 

 

Design and development

 The AS332 Super Puma, designed as a growth version to replace the SA 330 Puma, first flew in September 1977.  It was fitted with two 1330 kW 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.
