 The comparable Fiat G.55 had 250 rounds for the fuselage gun but also 600 for a 12.7 mm machine gun.The smaller Re.2005 also carried 100 fewer 20 mm but 100 more 12.7 mm rounds, a lighter armament array.The aft fuselage was unusually small, even by Italian standards and contained the radio equipment, oxygen bottles and supported the relatively large fin.
