Relying on their own resources, due to trade embargoes with South Africa, Atlas Aviation produced an experimental tandem-seat attack helicopter based on the Alouette III which was designated the Alpha XH-1.

The Alpha XH-1 was purely a test-bed for weapon and cockpit systems. It was fitted with a GA-1 Rattler 20mm cannon in a steerable turret, linked to a Kukri helmet-mounted sight. During 1987, the first of two XTP-1 Puma-based test-beds were built and used to evaluate engines, avionics, optronics, weapons and associated control systems for the larger airframe. These test-beds also included the use of locally-produced composite materials used in both airframe and rotor systems.
