Company withdraws from UJTS partnership as Sierra Nevada continues with its Freedom proposal
Northrop Grumman has withdrawn from its partnership with Sierra Nevada Corporation (SNC) on the company’s bid to develop the US Navy’s next-generation training system for naval aviators.
Northrop joined SNC’s Freedom proposal in February 2026 for the Undergraduate Jet Training System, or UJTS. The two companies have now confirmed that their agreement is no longer in effect.
“As part of our disciplined portfolio management and ongoing commitment to prioritizing the warfighter, we have elected to focus our resources on opportunities where our mature capabilities and investments can deliver the greatest mission impact,” Northrop Grumman said in a statement.
The company added that it remains committed to naval aviation and to delivering the capabilities required by the US military with speed and urgency.
Sierra Nevada presses ahead with Freedom
Northrop’s withdrawal has not, at least for now, altered Sierra Nevada’s plans. The company said it will continue promoting its Freedom proposal for the Navy’s advanced training program.
SNC said its objective remains to provide the most capable training system available for the Naval Aviation Mission.
General Atomics–Aeronautical also confirmed that it will remain part of Team Freedom, continuing its participation in the proposal alongside SNC.
Competition for the Navy’s future trainer narrows
Textron and Leonardo remain the main rival team
The Freedom proposal is competing against Textron Aviation Defense, which is offering the Beechcraft M-346N as part of a partnership with Leonardo.
The UJTS program is intended to replace existing training platforms and provide a modern system for preparing pilots who will operate the US Navy’s future combat aircraft.
The field has already narrowed after Lockheed Martin announced in April that it would not submit its TF-50N proposal with Korea Aerospace Industries. Boeing followed in June by announcing that it would also leave the competition.
Navy decision delayed until 2027
It remains unclear when the Navy will select a winner. In September, the service postponed its decision until June 30, 2027.
The delay extends uncertainty for the companies involved in one of the US Navy’s most significant efforts to modernize naval aviation training.
Northrop awaits F/A-XX decision
Company remains involved in a strategic sixth-generation fighter program
While stepping away from the UJTS competition, Northrop Grumman is awaiting the Navy’s decision in the F/A-XX program, which is focused on developing the service’s future sixth-generation fighter.
Northrop is competing directly against Boeing, and the Navy is expected to announce a winner in the near future. However, the decision timeline has repeatedly shifted, leaving the next phase of the program uncertain.
