The U.S. Navy has officially received 15 units of the Textron T-54A Marlin II training aircraft, marking a major step in its effort to modernize pilot training.
In May, the Navy declared Initial Operational Capability (IOC) for the T-54A, making the aircraft ready for training missions.
The T-54A is replacing the aging T-44C Pegasus, which the Navy has started to retire. Designed for multi-engine training, the new platform features side-by-side cockpit seating, modern avionics, and a pressurized cabin. It also includes a jump seat for instructors or observers, enabling improved training capabilities for student aviators entering multi-engine and tilt-rotor fleet roles.
A key advancement in the T-54A is its data-driven maintenance system. The aircraft is equipped to track its mechanical condition over time, helping the Navy shift toward condition-based maintenance and long-term fleet health planning.
The U.S. Navy plans to acquire up to 64 T-54A aircraft by 2026 under a contract awarded to Textron in 2023. The system is expected to meet training requirements for the Navy, Marine Corps, Coast Guard, and selected U.S. allies through 2055.
The T-54A program is managed by PMA-273, under the Program Executive Office for Tactical Aircraft Programs, which oversees a range of naval flight training systems essential to preparing aviators for current and future missions.
