The Douglas A-26 entered the Second World War at a relatively late date: the first eighteen examples were, in fact, sent to the European front in the summer of 1944. However, shortly afterwards, the Invader demonstrated its worth, and on the cease fire the troops equipped with these planes had flown more than 11,000 missions. Also in the Pacific, in only a few months, the Invader consolidated its fame as the crew's favourite bomber. After a short period of time, the A-26 found itself fighting again in Vietnam. It then became the average standard bomber of the USAF used in the War in Korea. It was in this conflict that the A-26C variant was more widely used; characterised by P&W R-2800-27 engines and a glass nose, which contained the Norden bombsight. Many examples were successively supplied to smaller air forces, which kept them in service until the middle of the 70's.
