"SNC’s decision was driven by the acquisition structure, not the aircraft, the team, or the mission," the company told TWZ — and then explained, in detail, why it walked away from a competition the U.S. Navy hopes will replace the T-45 Goshawk fleet.
Why Sierra Nevada Corp said the firm-fixed-price setup was fatal
Sierra Nevada Corp (SNC) tied its withdrawal from the Undergraduate Jet Training System (UJTS) contest to the Navy’s insistence on a firm-fixed-price (FFP) production contract before the aircraft design had fully matured. SNC said the solicitation “requires industry to commit to firm-fixed-price production before the aircraft design has fully matured,” creating a level of risk the company “could not responsibly accept.”
The story’s source material explains the basic mechanics of an FFP arrangement: customer and vendor agree a hard cost figure up front, and cost growth due to delays and other factors is generally shouldered by the vendor, although renegotiation is possible. SNC framed three related worries: FFP production before design maturity, limited visibility into the program’s long-term funding profile, and the requirement “to lock in production pricing before key design decisions are finalized.”
The article places SNC’s concern in a broader context included in the reporting: debates over FFP have looked particularly sharp in recent years, with Boeing cited as “a poster child for the pitfalls” after multibillion-dollar losses on several fixed-price projects. The story also notes an April executive order by President Donald Trump that declares “it is the policy of my Administration that fixed-price contracts with performance-based considerations should serve as the default and preferred method of procurement...”
Freedom clean-sheet design vs. the mature M-346N
SNC had planned to offer a clean-sheet design, the Freedom jet, and had promoted it for more than a year as the only clean-sheet competitor for UJTS. At the time of the reporting, SNC said a Freedom prototype “has yet to fly.” By contrast, the only publicly known entrant remaining in the competition is the Beechcraft M-346N, a U.S.-Italian entry from Textron and Leonardo that is “based on the established M-346 Master jet trainer,” a platform already in widespread operational service.
SNC told TWZ it continued developing Freedom to be carrier-capable and to perform simulated carrier touch-and-goes on land, even though the Navy removed actual carrier operations from UJTS requirements. SNC insisted its withdrawal “does not reflect any change in confidence in the Freedom Trainer” and that the aircraft “was designed specifically for naval aviation training as a clean-sheet, carrier-capable solution intended to deliver modern training capability and long-term lifecycle savings.”
Textron, meanwhile, framed the M-346N as a lower-risk option: “Textron Aviation Defense also brings an established American workforce, supply chain and production capability to support delivery at scale. Combined with a mature Integrated Training System that brings together live, virtual and constructive training, the M-346N offers the U.S. Navy a low-risk solution designed to prepare aviators for the demands of the high-end fight,” the company told TWZ.

End the scrambleExport potential and SNC’s pitch to fold allies into funding
SNC said it repeatedly engaged with the Navy and PMA-273 (the Naval Undergraduate Flight Training Systems Program Office at NAVAIR) and proposed avenues to reduce risk. Those proposals included “additional risk-reduction activities through preliminary design review, proposals based on more mature designs and acquisition approaches that better align production commitments with design maturity.”
SNC also emphasized export and Foreign Military Sales (FMS) as a lever to improve affordability. The company told TWZ there are “more than 600 FMS trainer aircraft requirements that could be combined in a joint program for the UJTS at a tremendous cost offset to the Department of War.” SNC urged “bringing our allied partnership and investment to the table to drive production and affordability on both the front end and the back end.”
The article notes a parallel: the Air Force’s T-7 program won in 2018 under a fixed-price structure and attracted international interest, yet “no export sales of T-7s have yet been announced,” and the T-7 program itself has “been beset by technical issues, delays, and cost growth.”
Program timing, funding and the competition’s thin field
UJTS seeks 216 new jet trainers to replace roughly 200 T-45s. The T-45 fleet began entering service in the early 1990s and has undergone upgrades, but aging airframes and sustainment problems persist. The reporting recalls hypoxia-like physiological episodes in the early 2020s that prompted a new oxygen system, and it notes several recent Goshawk crashes — including a May loss in which the two people onboard survived.
The Navy has already pushed and reworked the UJTS schedule: the original goal was to start receiving aircraft in 2028, but the initial contract for the program is now not expected until the fourth quarter of Fiscal Year 2027 (July–September of next year). The Navy also increased the program’s total cost ceiling from about $1.8 billion to $2.7 billion earlier this year. SNC cited “limited visibility into the program’s long-term funding profile” as one of its reasons for stepping away.
With SNC out, the article notes that the Beechcraft M-346N appears “as the only known entrant” remaining. The Navy told TWZ it is “restricted from disclosing this information or commenting on active proposals” and that “source selection information including bidder identities and proposal details, are restricted from public disclosure.”
What this means for the Navy, Textron/Leonardo, and SNC
- The Navy: The service is continuing with UJTS despite a sole publicly known entrant; the program office cited rules restricting comment on active proposals, even as schedule slips and increased cost ceilings change program dynamics.
- Textron and Leonardo: Textron described the M-346N as a “low-risk solution” supported by an established U.S. workforce, a mature training system, and production capability “to support delivery at scale.”
- Sierra Nevada Corp: SNC says it remains willing to re-engage if the Navy revisits acquisition approaches. “Ultimately, the Navy is best positioned to determine the path forward, and we stand ready to re-engage if the approach is revisited,” the company told TWZ, adding that “robust competition delivers the best value for the Navy and the taxpayer over a program of this duration.”
The record in the reporting is concrete: SNC left UJTS because of contractual design and funding requirements; the Navy has a single publicly known bidder; and program timing and costs have shifted. The unanswered, but immediate, fact is procedural: the contract award window remains slated for late next year, and the Navy’s acquisition choices between now and then will determine whether the competition widens — or whether the M-346N goes forward as the de facto front-runner.
