R. Having little development time available, Reggiane considered various options, including the potential for manufacturing an American-developed fighter aircraft under license instead; however, under the influence of aeronautical engineer Giovanni Battista Caproni, a completely original design was rapidly prepared. The design team took inspiration from the contemporary American fighter Seversky P-35; their resulting design, the Reggiane Re.2000, bore a superficial resemblance to the P-35. It was the first aircraft to be designed by Reggiane to employ aluminum stressed skin construction, as opposed to the wooden or mixed wood and metal structures that had been traditionally used in contemporary Italian aircraft such as the Savoia-Marchetti SM.79, another aircraft which had also been produced by Reggiane under license. On 24 May 1939, the prototype Re.2000 conducted its maiden flight at Reggio Emilia, Emilia-Romagna, Italy, flown by Mario De Bernardi. According to Cattaneo, early flights had quickly demonstrated the type's favourable flying attitude, including good speed and high manoeuvrability. Only minor modifications were required after the successful completion of the initial factory flight test programme; these including changes to the exhaust, the lengthening of the carburetor air intake, and the replacement of the round windshield with a framed counterpart. During testing, the Re 2000 demonstrated the ability to perform better than other existing fighters then in production. In mock dogfights, it could successfully fight not only the slower Fiat CR.42 biplane, but even the more modern Macchi C 200 and the German Messerschmitt Bf 109E fighters. However, the Re.2000 was afflicted by a major handicap in the form of the unavailability of reliable in-line engines of sufficient power; as such, the RE.2000 was able to represent only a limited advance over the rival Macchi C.200. Throughout the Second World War, the company would develop numerous improved variants of the Re.2000, including the Re.2001, Re.2002, Re.2003, Re.2004, Re.2005, and Re.2006, some of which never progressed beyond the stages of prototyping or limited production. It has been alleged that the Reggiane had been working on developing their own wartime jet-propelled fighter, the Re.2007; however, some figures have cast doubts over the authenticity of the documentation produced. Postwar activities Following the conclusion of the conflict, Reggiane's factory was occupied by a large contingent of its work force, during which time its works were converted for to produce goods orientated towards the civilian market instead. This industrial action followed a pattern similar to the nationwide wave of
