VT-4 Training Squadron 4 is a training squadron of the United States Navy. Initially established as Basic Training Group NINE (BTG-9) in the 1950s, the squadron was redesignated as Training Squadron FOUR (VT-4) on May 1, 1960 and based at Naval Air Station Pensacola, Florida. General information Advanced training for USN Naval Flight Officers (NFO) destined for E-2 Hawkeye, E-6 Mercury, EP-3 Aries, and P-8 Poseidon aircraft. The squadron's radio callsign is Buck. History Its original mission was providing flight instruction for US Navy and US Marine Corps Student Naval Aviators in the basic jet training syllabus utilizing the T-2A version of the T-2 Buckeye aircraft. In 1965, Training Squadron FOUR transitioned to the T-2B aircraft and its mission was modified to become the Naval Air Training Command's sole site for providing student pilots with basic jet flight instruction in aerial gunnery and carrier qualification. In 1971, Training Squadron FOUR transitioned to the T-2C aircraft. The squadron mission was changed once again, to provide flight training in all phases of the basic jet syllabus. In September 1972, Training Squadron FOUR acquired the TF-9J providing flight instruction in both basic and advanced jet training. This mission was unique in the Naval Air Training Command in that student pilots experienced their first flight in a jet aircraft in VT-4 and remained aboard to be subsequently designated Naval Aviators. November 1973 saw the introduction of the TA-4J to replace the aging TF-9J for advanced flight training. Beginning in December 1975, VT-4 had the added mission of providing flight instruction for allied foreign military pilots. Flight training has been given to student pilots from Kuwait, Spain, Singapore and Indonesia. In addition to pilot training, VT-4 has had two other significant missions. From 1973 to 1978, VT-4 provided summer jet orientation flights for midshipmen of the United States Naval Academy and the Naval Reserve Officers Training Corps. From 1975 to 1979, VT-4 was also responsible for the training of Naval Flight Surgeons. In December 1985, VT-4's mission was changed from strike training to the sole site of E-2/C-2 intermediate training in CNATRA. In this role, the squadron carrier qualified Student Naval Aviators from the multiengine training pipeline, informally called the "prop pipeline," who we selected to eventually fly the E-2 Hawkeye and C-2 Greyhound aircraft in the Fleet. Graduates of VT-4 would receive their wings and designations as Naval Aviators and proceed to the Fleet
