F4U-5N and -5NL Corsair night fighters were used to attack enemy supply lines, including truck convoys and trains, as well as interdicting night attack aircraft (such as the Polikarpov Po-2 "Bedcheck Charlies", which were used to harass United Nations forces at night). The F4Us often operated with the help of C-47 'flare ships' which dropped hundreds of 1,000,000 candlepower magnesium flares to illuminate the targets. For many operations detachments of U.S. Navy F4U-5Ns were posted to shore bases.
