The aircraft had considerably more training capability than the aircraft it replaced, the T-29. Introduction of the T-43 into Air Force Undergraduate Navigator Training (UNT) in 1974 also enabled the United States Navy to disestablish Training Squadron TWENTY-NINE (VT-29) and its T-29 aircraft at Naval Air Station Corpus Christi, Texas in 1975. VT-29 had been training student Naval Flight Officers for various land-based naval aircraft such as the P-3 Orion, EP-3 Aries, and variants of the Lockheed C-130 Hercules. The Navy then merged its Student NFO (SNFO) "NAV" pipeline with the Air Force's UNT program in 1976, forming Interservice Undergraduate Navigator Training (IUNT) with both Navy students and USN and USAF instructors.
