no there were Bombers (many) and a few fighters, that bore us markings, a kind of genric scheme. The bombers were used as gunner spoters for AAA, or to vector fightes. Not very a popular task by anymeans. Most fighters were as trainers, or target drone type stuff, to proud to admit that they had in their possion a better fighter than what they had in the air. These were studied to Imporve their fighter designs.
One of the few cases that you will see of a airforce stealing tech and plane design was the russian version of the B-29. A blantant Copy of the B-29, produced for russian service.
