The Navy's contest for a new jet trainer is now effectively a one-horse race. Sierra Nevada Corporation (SNC) told Breaking Defense it could not responsibly bid the Undergraduate Jet Training System (UJTS) program under the current contract structure, leaving Textron Aviation Defense and its M-346N as the only confirmed major competitor. For readers tracking the program, the practical question is no longer who wins. It is when the award lands and whether the competition reopens.
This guide lays out the confirmed timeline, the requirements the Navy has published, and the specific markers to watch between now and contract award. The award is currently expected in the fourth quarter of fiscal year 2027, according to Breaking Defense, which reported SNC's withdrawal on Nov. 3, 2026.
What Is The UJTS Program And Why Does It Matter?
UJTS stands for Undergraduate Jet Training System. It is the Navy's program to replace the T-45 Goshawk, the jet that has trained Navy and Marine Corps aviators for carrier aviation and tactical strike missions since it entered the fleet in the early 1990s. The trainer matters to the community this publication serves because every future naval jet pilot passes through the aircraft that replaces the T-45.
One requirement change is worth understanding up front. The T-45 lands on aircraft carriers. The new trainer does not have to. In a March request for proposal (RFP), the Navy said it will not require the new jet to perform carrier landings. It also will not require the aircraft to support field carrier landing practice (FCLP) touch-downs, the drill that simulates a carrier landing on a runway. The aircraft must support FCLP to wave off only, and the Navy asked industry to share unique aircraft simulation capabilities to train aviators for carrier landings.
Who Is Still In, And Who Has Walked Away?
The field narrowed steadily through 2026. Here is the confirmed sequence, all drawn from Breaking Defense's reporting: This connects to our earlier piece, Why Missile Defense Systems Are Stationed at Mar-a-Lago Right Now.

- April: Lockheed Martin announced it would not submit its offer of the TF-50N with Korea Aerospace Industries.
- June: Boeing announced it would no longer participate in the competition.
- September: Northrop Grumman dropped off SNC's bid, which was built around a clean-sheet design called the Freedom. SNC had announced in February that Northrop Grumman and General Atomics Aeronautical Systems had joined the team, as Aviation Week reported.
- Nov. 3: SNC confirmed it did not bid by the Oct. 30 deadline, citing the current contract structure. Textron confirmed it submitted the M-346N.
SNC's statement to Breaking Defense read: "With great respect for the Navy and PMA-273, SNC could not responsibly bid the UJTS [Undergraduate Jet Training System] program under the current contract structure. We do remain committed to naval jet training and stand ready to re-engage if the approach is revisited." PMA-273 is the Navy program office that manages naval pilot training aircraft.
One wildcard remains. Stavatti Aerospace, a firm that regularly claims to have designs for Pentagon contracts, said on Oct. 30 that it submitted a bid on UJTS. Barring a reopened competition or a surprise entrant, Breaking Defense reports the M-346N appears to be the de facto winner.
The Timeline: What Has Slipped And What Is Fixed
Two dates are fixed and two have moved. Readers can track the program against this checklist:
- Fixed: The Oct. 30 bid deadline held. The program office confirmed the service stuck to it, after extending it once from a previous RFP deadline of June 30.
- Fixed: The Navy is in source selection now. The program office stated: "The Government is in source selection with the intent to award the UJTS procurement in 4QFY27."
- Moved: The Navy originally planned to select a winner in March 2027. A September RFP pushed that to June 2027.
- Moved again: The service now estimates award sometime between July and the end of September 2027.
The practical takeaway: if no award appears by the end of September 2027, that would be another slip worth noting. If the award arrives earlier, that would signal the source selection moved faster than the current estimate.
Three Markers To Watch Before Award
Given the reported facts, three developments would change the picture:
- A reopened competition. SNC said it stands ready to re-engage if the approach is revisited. Any change to the contract structure could bring the Freedom design back into play.
- The Stavatti bid. If the Navy treats the Stavatti submission as a valid competitor, the field is not a single bidder in formal terms.
- The award announcement itself. The contract value, recipient and delivery timeline will be stated when the award is made in the July-to-September 2027 window.

Where The Official Record Lives
The authoritative source for UJTS status is the Navy's program office, PMA-273, which confirmed the bid deadline and the award window to Breaking Defense. The published RFP documents, including the March and September notices cited in that reporting, carry the requirements: no carrier-arrested landing, FCLP to wave off only, and a call for unique aircraft simulation capabilities for carrier-landing training. Readers who want the official word should watch for the contract award announcement in the fourth quarter of fiscal year 2027. Until then, the confirmed record is simple: one major bid submitted, one contract structure that drove a respected competitor away, and an award date that has already moved twice.
