First Boeing-Saab T-7 Red Hawk Advanced Jet Trainer Joined in Record Time

In one historic moment, the front fuselage of the first Boeing-Saab T-7A Red Hawk advanced trainer was joined perfectly with its aft section in less than 30 minutes — a testament to the digital heritage of the U.S. Air Force’s first “eSeries” aircraft and witness to the benefits of model-based engineering and 3D design. The digital splice was completed in 95% less time than traditional splices and with substantial quality improvements.

“What we’re seeing in this new evolution of digitally designed, engineered and manufactured aircraft is a 50% improvement in overall production quality and as much as a 98% reduction in drilling defects,” said Andrew Stark, Boeing T-7A Red Hawk production director. “It’s a new way of producing airplanes with improved quality throughout the whole journey.”

“This moment marks a key stage in the evolution of the T-7A Red Hawk,” said Chuck Dabundo, vice president and program manager of Boeing T-7 programs. “Employing digitally advanced manufacturing and build techniques developed by Boeing over the past two decades, we are bringing this trainer to future pilots sooner than ever before possible and with greater quality.”

The aft fuselage was designed and built by Saab in Linköping, Sweden, under a joint development agreement with Boeing. After making the journey of more than 4,500 miles (7,200 kilometers) to St. Louis, the aft section was lined up perfectly to the forward fuselage by Boeing aircraft mechanics. The aircraft, which will be used for static test, is the first engineering and manufacturing development test asset to be spliced. It will be followed by five engineering and manufacturing development jets as part of 351 T-7A Red Hawk trainers to be produced for the U.S. Air Force.

The Boeing-Saab T-7 Red Hawk, originally known as the Boeing T-X, is an American/Swedish advanced jet trainer produced by Boeing in partnership with Saab. It was selected on 27 September 2018 by the United States Air Force (USAF) as the winner of the T-X program to replace the Northrop T-38 Talon.

In cooperation with its Swedish aerospace partner, Saab, Boeing’s submission to the competition was the Boeing T-X, a single-engine advanced jet trainer with a twin tail, tandem seating, and retractable tricycle landing gear. The submitted aircraft and demonstration models featured a General Electric F404 afterburning turbofan engine. Boeing intends to offer an armed version of the T-7 as replacement for aging Northrop F-5 and Dassault/Dornier Alpha Jet fleets around the world. The design officially entered production in February 2021.
