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 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 Mauser MG 151/20 cannon in two gondolas, one under each wing, although many fighters retained the original armament. A total of 34 CNs were produced of the 50 ordered.
