US Navy’s T-54A Marlin II Achieves Initial Operational Capability, Replacing Aging Trainer Fleet

The US Navy’s T-54A Marlin II training aircraft has recently reached initial operational capability (IOC), officially replacing the aging T-44C Pegasus fleet used since the 1970s.

The milestone marks a major modernization in naval aviation training with a platform tailored for today’s battlespace.

Developed by Textron and based on the Beechcraft King Air 260, the T-54A offers advanced avionics, updated navigational systems, and a pressurized cockpit with side-by-side seating and an extra jump seat. It also includes data-capture systems for condition-based maintenance, enhancing fleet readiness and reducing long-term costs.

The Navy currently operates 15 T-54As and plans to procure a total of 79 aircraft by 2026 under contracts awarded to Textron in 2023 and expanded in 2024.
