Lockheed’s engineers have been reviewing the Navy’s latest RFI to determine what added work the aircraft would need. Though the requirements for unflared landings and glideslope would put stress on a trainer’s airframe over its lifespan, the company is confident it will meet the Navy’s requirements.
The increased emphasis on the carrier landing profile and repeated unflared landings is new in the August RFI, compared to previous versions released as early as 2018. Specifically, the document calls for an aircraft that can maintain a fixed angle-of-attack approach targeting a 3-deg. glideslope while maintaining field of view during an unflared landing. The aircraft needs to be capable of 6-10 unflared landings per training event, as well as conducting unflared landings throughout its service life.
To further replicate carrier operations, the aircraft must be able to maintain control and come to a stop on a minimum 6,000-ft.-long X 100-ft.-wide runway. In performance, the aircraft needs to be capable of Mach 0.9, a 7.33g sustained load factor and a ceiling of 41,000 ft.
Driving home the importance of FCLP operations, the Navy is inviting industry to a training base in Texas in October to monitor T-45 touch-and-goes in the flight profile “to enhance industry’s understanding of the unique Navy landings.”
