Replacement Squadron. In January 1992, VT-4's mission became the E-2/C-2 advanced training site. To accomplish this mission VT-4 flew the T-2C. During 1996, VT-4 underwent significant change. From a small all Navy Advanced E-2/C-2 pilot training squadron with a student throughput of 36 per year, it became a joint Primary and Intermediate Naval Flight Officer/Navigator training squadron with an annual student throughput of 450. Instructor ranks grew from fourteen Navy pilots to 71 Navy, Marine Corps and Air Force pilots and NFO/Navigators. The squadron transitioned from flying the T-2C to flying the T-34C Turbo Mentor and T-1A Jayhawk. VT-4 also instructs student navigators from Germany, Italy, Saudi Arabia, Norway and Denmark. From April to September 1996 the squadron had primary NFO/NAV and advanced pilot training being conducted simultaneously. Following the final CQ detachment in September, the mission converted entirely to NFO/NAV training. On 30 September 1996, the last VT-4 Naval Aviators earned their wings. In January 2003, VT-4 initiated instructor orientation flights in the T-6A "Texan II", the joint Air Force/Navy platform slated to replace the T-34C as the Primary phase syllabus trainer. The T-6A "Texan II" is a single engine, two-seat trainer which is fully aerobatic. It features a pressurized cockpit, a G-tolerance enhancement system and dual zero-zero ejection seats. The T-6A utilizes a state-of-the-art digital cockpit to help familiarize students with what they will encounter in their fleet tours. In August 2003, VT-4 marked its first training flight in the T-6A "Texan II". In April 2005, VT-4 completed the transition to the T-6A "Texan II" and flew its last T-34C "Turbomentor" student sortie. In December 2010, VT-4 was deactivated and all VT-4 instructors and students became a part of VT-10. VT-4 was reactivated in June 2013, no longer flying the T-39 Sabreliner and has introduced the Multicrew Simulator (MCS) to TRAWING SIX. VT-4 is the winging squadron for all NFOs destined for the E-2 Hawkeye, E-6 Mercury, EP-3 Aries, P-3 Orion and P-8 Poseidon, relieving the respective Fleet Replacement Squadrons (FRS) for those type/model/series (T/M/S) aircraft of that responsibility. Since its establishment, VT-4 has amassed over 600,000 flight hours. The squadron has logged 42,000 carrier landings.
