The Global Race: Who's Leading the Charge?
The development of sixth-generation aircraft is not a solitary endeavor but a fiercely competitive global race, with several nations and multinational consortia investing heavily in conceptualization, design, and prototyping. Each program brings its own strategic priorities and technological approaches to the table, fueling an intense competition for air dominance.
Here’s a look at the key players and their ambitious programs:
United States: NGAD and F/A-XX
The U.S. has two major programs underway:
- USAF Next Generation Air Dominance (NGAD) Program: Launched in 2014 to eventually replace the F-22 Raptor, the USAF confirmed a prototype flew in September 2020 and selected the Boeing F-47 design in 2025. This program emphasizes extreme stealth, long range, supersonic speed, and a large payload, often implying a tailless design to counter low and high-frequency radars.
- USN F/A-XX Program: Aimed at replacing the F/A-18E/F Super Hornets, the Navy’s focus balances survivability with speed and payload for carrier operations. Both U.S. efforts prioritize AI as a pilot aid, non-GPS positioning-navigation-timing, and extensive data movement. Adaptive cycle engines are under development to provide optimal efficiency across the entire flight envelope.
China: J-36, J-50, and the Future J-XX
China is rapidly advancing, having reportedly test-flown two sixth-generation prototypes: the Chengdu J-36 (a trijet tailless flying wing, flown December 26, 2024) and the Shenyang J-50 (a cranked arrow configuration, flown December 20, 2024, though unconfirmed). A third tailless prototype spotted in August 2025 hints at further developments, possibly a loyal wingman drone or a carrier-based fighter. China’s program, which began pre-research in January 2019, targets exponential improvements in stealth, processing power, and sensing, aiming for fruition by 2035 with an open mission systems approach.
