Shortly following the completion of the second prototype, an initial order for 99 production aircraft was placed with Macchi. The G.50, which during the same flight tests held at Guidonia airport had out-turned the Macchi, was also placed in limited production, because it had been determined that the former could be brought into service earlier. The decision, or indecision, involved in producing multiple overlapping types led to greater inefficiencies in both production and in operation. In June 1939, production of the C.200 formally commenced.
