Ultimately, it was decided to adopt both the powerplant and dynamic systems of the Oryx—which bore significant similarities to their Puma and Aérospatiale AS332 Super Puma ancestors—as the basis for the planned attack helicopter; commonality with the Oryx systems would simplify logistics and reduce maintenance costs.
