“With great respect for the Navy and PMA-273, SNC could not responsibly bid the UJTS program under the current contract structure,” Sierra Nevada Corporation said in a statement to Breaking Defense, announcing its withdrawal from the Navy’s Undergraduate Jet Training System competition.
Sierra Nevada Corporation withdraws from UJTS
Sierra Nevada Corporation (SNC) informed Breaking Defense that it did not submit a formal bid for the Navy’s UJTS by the Oct. 30 deadline because it could not “responsibly bid” under the program’s current contract structure. SNC added that it “do[es] remain committed to naval jet training and stand ready to re-engage if the approach is revisited.” The company’s proposal had been built around a clean-sheet design called the Freedom; earlier reporting noted Northrop Grumman had dropped off that SNC-led bid in September.
Textron Aviation Defense appears to be the lone major competitor with the M-346N
Textron Aviation Defense confirmed via email to Breaking Defense that it submitted an offering of the M-346N to the Navy and that the firm is “ready to support the U.S. Navy and its future training needs.” With SNC out of the running and other major primes having exited earlier in 2026, the M-346N stands as the de facto front-runner — barring a reopening of the competition or a surprise entrant.

The competitive landscape had thinned over months: Lockheed Martin announced in April it would not submit the TF-50N with Korea Aerospace Industries; Boeing announced in June it would not participate; and Northrop Grumman dropped from SNC’s Freedom-based bid in September. On Oct. 30, Stavatti Aerospace said it submitted a bid, but the major known contenders now reduce to Textron’s M-346N unless the Navy reopens the field.
Navy’s schedule, requirements, and RFP timeline
The Navy’s UJTS program office told Breaking Defense that industry was held to an Oct. 30 RFP deadline, an extension from an earlier June 30 deadline. The office also pushed back the expected contract award window: where the Navy’s September RFP had projected an award in June 2027, the service now estimates an award sometime between July and the end of September 2027, stating the Government intends to award the UJTS procurement in 4QFY27. The award date had been moved previously; the Navy originally planned a selection in March 2027.
The Navy has specified that, unlike the retiring T-45 Goshawk — which lands on aircraft carriers and first entered the fleet in the early 1990s — the new UJTS aircraft will not be required to perform carrier landings. The service also said it will not require field carrier landing practice (FCLP) to touch down; instead, aircraft must support FCLP to wave off. The Navy asked industry to share “unique aircraft simulation capabilities” to prepare aviators for carrier landings.
What this means for the Navy, Textron Aviation Defense, and Sierra Nevada Corporation
- The Navy: With SNC’s withdrawal and earlier exits by other primes, the Navy faces a potential single-supplier outcome unless the service reopens competition. The program office’s updated award window — 4QFY27 — sets a near-term deadline for either finalizing an agreement or deciding to alter the procurement approach.
- Textron Aviation Defense: Having confirmed submission of the M-346N, Textron is positioned to be the apparent winner if no other major bids arrive. The company’s public statement says it is “ready to support the U.S. Navy and its future training needs,” signaling preparedness for contract performance should an award be made.
- Sierra Nevada Corporation: SNC framed its exit as a response to contract structure rather than abandonment of naval training generally, explicitly stating it stands ready to re-engage if the approach is revisited. That leaves open the possibility of a return if the Navy modifies terms.
The Navy’s UJTS competition has now reached a point where program structure and timing matter as much as aircraft capability: SNC’s public withdrawal points to contractual constraints shaping the field as much as technical performance. With the M-346N standing as the known, submitted offer and an award window set for 4QFY27, the central questions left on the table are procedural — will the Navy alter the contract structure or reopen the competition — and scheduling — will the program office proceed to an award in the July–September 2027 window or take further steps to broaden competition?
