The Undergraduate Jet Training System program, or UJTS program, is a United States Navy development and acquisition program for a new two-seat jet trainer to replace the McDonnell Douglas T-45 Goshawk.

History

The US Navy launched the first Request for Information (RFI) to replace the T-45C in 2020, with subsequent RFI's following in 2021, 2023, and 2024, with each RFI modifying the needs and requirements for the program.

Requirements

Competitors

Boeing-Saab T-7B

Main article: Boeing–Saab T-7 Red Hawk

On 23 February 2021, it was announced that Boeing would pitch a variant of the T-7 Red Hawk to the US Navy as the T-7B. It was further announced that the T-7B would compete as Boeing's entry to the US Navy's Tactical Surrogate Aircraft program, which seeks an aggressor aircraft. In 2023, Boeing stated that it would modify the T-7 to meet FCLP requirements.[2]

Lockheed Martin-KAI TF-50N

Main article: KAI T-50 Golden Eagle

In 2021, Lockheed Martin announced a partnership with Korean Aerospace Industries (KAI) to pitch the T-50 to the US Navy as the TF-50N.[3][4] The TF-50N is developed from Lockheed Martin and KAI's previous entry of the T-50A to the Air Force's T-X program.

Beechcraft M-346N

Main article: Alenia Aermacchi M-346 Master

Speculation began circling that the M-346 would be offered for the UJTS Program in 2020, following the Navy's inital RFI.[5]

On 4 August 2021, Leonardo announced it would enter the UJTS competition with the M-346 at Sea Air Space 2021. It claimed that the M-346 would be capable of FLCP cycles and touch-and-goes on carriers.[6] On 17 September 2023, it was announced that Leonardo would partner with Textron Aviation to market the M-346 to the US Navy as the M-346N ITS. On 28 July 2028, Textron announced that the entry would be known as the Beechcraft M-346N.

On 17 September 2025, Beechcraft announced it would begin a nationwide tour to demonstrate the M-346N. The M-346N being used in the tour is a modification of the M-346FA prototype, and began flying in the US as early as 9 September 2025.[7][8]

SNC Freedom Jet

Sierra Nevada Corporation's "Freedom Jet Trainer" was originally unveiled to the public in 2017, when SNC (partnering with Turkish Aerospace Industries) revealed a mockup of it as a competitor for the Air Force's T-X program.[9] It was intended as a direct competitor to the similar Textron AirLand Scorpion as well.[10] After the Boeing/Saab T-7 Red Hawk won the T-X contract, no further work was noted on Freedom until August 2023, when SNC teased a photo of Freedom in an orange-and-white paint scheme.[2]

On 21 August 2025, SNC revealed its entry to the UJTS program at Tailhook 2025, an annual naval symposium organized by the Tailhook Association, where a mockup of an updated, navalized Freedom Jet was on display.[11] Freedom is a twin-engine, twin-tail, subsonic jet trainer powered by two Williams FJ44-4M turbofans. SNC claims that Freedom will be able to perform carrier landings or touch-and-go's, a quality that was dropped from the UJTS's requirements.[12]

Stavatti SM-31N Stiletto

On 13 July 2020, Stavatti Aerospace announced that they had submitted their SM-31T design as a response to the Navy's UJTS RFI.[13] Following subsequent updates to the US Navy's requirements, Stavatti made press releases announcing their continued SM-31T submission in 2023[14], 2024[15], and 2025.[16] There is intense skepticism about Stavatti's ability to deliver to the US Navy, with the company's failure to assemble manufacturing facilities or produce any substantial results or products. The SM-31T has been referred to as a "Long-Shot" entry to the UJTS program.[17]
