The production T-37A was similar to the XT-37 prototypes, differing only in only minor ways as to address problems revealed by flight testing. During September 1955, the first T-37A was completed, it made its first flight later that year. The USAF ultimately ordered 444 T-37As, the last of which was produced in 1959. During 1957, the US Army evaluated three T-37As for battlefield observation and other combat support roles, but eventually procured the Grumman OV-1 Mohawk for this purpose instead. Darling alleges that this outcome had been largely due to political factors, including the opposition of the USAF.
USAF officials reportedly liked the T-37A but often considered it to be underpowered; consequently, the service ordered an improved version, the T-37B. It was outfitted with uprated J-69-T-25 engines that provided roughly 10 percent more thrust as well as being more reliable. The new variant also featured improved avionics, fuel flow improvements, as well as various changes to reduce maintenance requirements. A total of 552 newly built T-37Bs was constructed through 1973. All surviving T-37As were progressively upgraded to the T-37B configuration as well, the rebuilding program being completed by July 1960.[

The T-37 can be traced back to the spring of 1952 and the issuing of a request for proposals by the United States Air Force (USAF) for what would become the "Trainer Experimental (TX)" program. The request called for a lightweight twin-seat basic trainer that would be suitable for introducing USAF cadets to jet aircraft. More specifically,
A dedicated attack variant of the T-37, referred to as the A-37 Dragonfly, was developed during the 1960s
Over the decades, the USAF made several attempts to replace the T-37, such as the abortive Fairchild T-46, however it remained in service with the USAF into the twenty-first century.
