Designed especially for the USAF, the training aircraft features the latest technologies, tools and manufacturing techniques.
Powered by a single engine, T-X will replace the USAF’s ageing fleet of T-38 Talon aircraft.
Boeing Defense, Space & Security president and CEO Leanne Caret said: "Our T-X is real, ready and the right choice for training pilots for generations to come.”
The Boeing T-X aircraft features twin tails, stadium seating and an advanced cockpit with embedded training.
The system also offers advanced ground-based training and a maintenance-friendly design for long-term supportability, Boeing said in a statement.
Saab president and CEO Håkan Buskhe said: "It’s an honour to build the future of Air Force training.
"We have created the best solution thanks to great cooperation and a clear strategy since day one."
The aircraft is expected to achieve initial operational capability in 2024.
Through the T-X programme, the USAF will be able to acquire new two-seat jet trainer for fast-jet training to replace the Northrop T-38 Talon, which is in service for more than 43.5 years.
More than 350 aircraft are expected to be ordered to replace the T-38, with plans to increase the overall purchase to more than 1,000.
