 Along with the fighter variant, two other main variants were developed to suit specialized roles.The Re.2001 CB ("Cacciabombardiere", Fighter-bomber) version produced from 1942 could carry a 100 or 250 kg bomb under the fuselage for the attack role.The CN ("Caccia notturno", Night fighter) version was adapted with the introduction of engine exhaust-flame dampers and a 20 mm Mauser MG 151/20 cannon in two gondolas, one under each wing, although many fighters retained the original armament.
