The SNB-2C is the designation given to AT-7s built for the US Army but transferred to the Navy while under construction. In the early 1950s, the SNB-2s were returned to Beech for re-manufacturing and modernization. They returned to service as SNB-5s. The designation was finally changed to UC-45J in the early 1960s when the Navy changed their primary mission from training to utility transport. Markings displayed on this airframe: U.S. Army, 1967
