The T-6 was developed with the aim to obtain a trainer that was economical but had all the characteristics of the fighter planes in service at the time. It rapidly became the trainer most widely used by the Allied forces. In all, about 15, 500 T-6 Texans were produced, & their use extended beyond the end of World War II. In the post-war period, in fact, Texans continued to fly with the colours of many nations, & they were also adapted to perform attack & surveillance functions, a much less pacific role than the one for which they were designed.
