T6

T6 is an alphanumeric designation used in multiple domains to label different models, versions, or classifications. The most widely recognized use is in aviation, where the T-6 Texan family comprises trainer aircraft designed in the 1930s by North American Aviation. These aircraft served as the standard primary trainer for the United States Army Air Forces and many allied air forces during World War II and the early Cold War, earning a reputation for ruggedness and versatility. The family was produced in large numbers and supplied under various designations, including Harvard and SNJ, by foreign operators.

In modern times, the T-6 Texan II is a turboprop trainer developed for the United States Air Force and Navy. It entered service in the 2000s and has since become a primary trainer through initial, primary, and advanced flight phases. It is powered by a turboprop engine and features modern avionics and egress systems to prepare pilots for more advanced aircraft.

Beyond aviation, T6 appears as a designation in other fields as model numbers, project codes, or classification schemes, reflecting the general practice of using alphanumeric strings to denote versions. The term is therefore ambiguous outside of context, and specific meaning should be inferred from surrounding material.
