Northrop Grumman has departed the Sierra Nevada Corporation-led industrial team competing to supply the US Navy’s next-generation undergraduate jet trainer. The team’s Freedom aircraft proposal will continue with Sierra Nevada Corporation and General Atomics Aeronautical Systems after Northrop’s withdrawal. Northrop had joined the GA-ASI and SNC partnership in February, approximately seven months before announcing its exit. In a statement reported by Breaking Defense, the company said it had decided to focus its resources on areas where its existing capabilities and investments could provide mission impact. US Navy Trainer Replacement ProgrammeThe Navy established the Undergraduate Jet Training System programme in 2018 to replace the T-45 Goshawk, a carrier-capable trainer that has been operated since the 1990s. The original competition brought together four major industrial teams. Subsequent withdrawals have reduced the field. Boeing and Saab were among the teams to leave the competition, ending their offer of the T-7A Red Hawk. Their withdrawal was linked to schedule and qualification concerns surrounding engine configuration requirements. The competition now involves two remaining industry combinations. Sierra Nevada Corporation and General Atomics are continuing with the clean-sheet Freedom trainer, while Textron Aviation and Leonardo are offering the Beechcraft M-346N. The programme’s timeline has also shifted. The US Navy has postponed its planned award decision until June 30, 2027, when it is scheduled to select the aircraft for the future undergraduate jet-training requirement.
