 The first order, amounting to 300 machines, was cut back with only 252 produced.This number included 100 Re.2001 "Serie I", "Serie II" and "Serie III" with armament variations, the Reggiane "Serie IV" fighter-bomber and 150 Re.2001 CN "Caccia Notturna", night fighter.Due to the wing redesign coupled with production delays, the first production aircraft were finally cleared for operational use in June 1941, nearly a year behind schedule.
