Junior Technician (JT) is a rank in the Royal Air Force, ranking between Senior Aircraftman and Corporal, with a NATO rank code of OR-2. It is only held by airmen in technical trades and by musicians. Airmen in non-technical trades progress directly from senior aircraftman to corporal. Junior technician is a pay grade and does not have a supervisory role. The rank was introduced in 1950 as part of a new grading system for technicians, wearing a single point up chevron. In 1964, when the grading system was abolished, JTs were retained, their badge changing to a four-bladed propeller.
