China says its fighter pilots are battling AI aircraft in simulated dogfights, and humans aren't the only ones learning

Chinese fighter pilots have been battling aircraft piloted by artificial intelligence in simulated dogfights to boost pilot combat skills, Chinese media reported.

Fang Guoyu, a People's Liberation Army Air Force brigade flight team leader and fighter ace, was recently "shot down" by an AI adversary in an air-to-air combat simulation, according to China's PLA Daily, the official newspaper of the Chinese military.

He said that early in the training, it was easy to defeat the AI adversary. But with each round of combat, the AI reportedly learned from its human opponent. After one fight that Fang won with a bit of skillful flying, the AI came back and used the same tactics against him, defeating the human pilot.

"It's like a digital 'Golden Helmet' pilot that excels at learning, assimilating, reviewing, and researching," Fang said, referring to the elite pilots who emerge victorious in the "Golden Helmet" air combat contests. "The move with which you defeated it today will be at its fingertips tomorrow."

Du Jianfeng, Fang's brigade commander, told the PLA-controlled newspaper that AI is increasingly being incorporated into training.

It "is skilled at handling the aircraft and makes flawless tactical decisions," he said, characterizing the AI adversary as a useful tool for "sharpening the sword" because it forces the Chinese pilots to get more creative.

China is striving to build a modern military with the ability to fight and win wars by the middle of this century, and it has made progress in recent years in advancing its air combat element, even developing a fifth-generation stealth fighter.

But far more challenging and time consuming than closing the technology gap is cultivating the critical knowledge and experience required to effectively operate a modern fighting force.

Chinese media did not offer specifics on the simulator, so there are questions about whether or not the AI adversary provides sufficiently realistic training necessary to prepare pilots to dogfight manned aircraft.

"If it does, that's pretty good," retired US Navy Cmdr. Guy Snodgrass, a former TOPGUN instructor and an artificial intelligence expert, told Insider.

"If it doesn't," he continued, "you're really just training human operators to fight AI, and that is probably not what they are going to be going up against" given that there are currently no autonomous AI-driven fighter aircraft they would need to be prepared to fight.

"There could be a divergence between real capability in a dogfight or aerial battle versus what the AI is presenting," he said. If that's the case, this could be wasted effort.

If it is a high-fidelity training simulator, though, it potentially lowers the cost of the air combat training because "you're able to get that training at a price point that's much lower than actually putting real planes in the air," Snodgrass said.

Chinese leader Xi Jinping has repeatedly stressed the need for realistic combat training, including simulations, to help the Chinese military overcome their lack of combat experience, but it is not clear to what extent his agenda has been implemented with training simulators like what PLAAF pilots have been using.

Regardless of whether the pilots are learning anything valuable, Fang Guoyu's recollection of his engagements with his AI adversary demonstrates that the AI is.

"AI requires feedback," Snodgrass said. "And that's exactly the kind of pathway you'd want to take, to use this to help train your pilots, but because your pilots are fighting against it, the AI is learning and it's getting better."

A next step, he explained, could then be to say, "This has performed very well in a virtual environment. Let's put this into a manned fighter."

Over the years, China has invested heavily in AI research, and, like the US, it has been considering ways to incorporate AI — which can process information quickly and gain years of experience in a short time — into the cockpits of its planes.

Yang Wei, chief designer for the J-20, China's first fifth-generation stealth fighter, said last year that the next generation of fighter could feature AI systems able to assist pilots with decisions to increase their overall effectiveness in combat, the state-affiliated Global Times reported.

The US Air Force has expressed similar ideas. Steven Rogers, a senior scientist at the US Air Force Research Laboratory, told Inside Defense in 2018 that ace pilots have thousands of hours of experience. Then he asked, "What happens if I can augment their ability with a system that can have literally millions of hours of training time?"

Snodgrass explained that there are a number of different ways AI could be used to augment the capabilities of a pilot.

For instance, artificial intelligence could be used to monitor aircraft systems to reduce task saturation, especially for single-pilot aircraft, collect battlefield information, and handle target discrimination and prioritization. AI could even potentially chart out flight paths to minimize detection through electromagnetic spectrum analysis.

The US is currently pursuing several lines of effort exploring the possibilities of AI technology.

In a big event last summer, the Defense Advanced Research Projects Agency (DARPA) put an AI algorithm up against an experienced human pilot in a "simulated within-visual-range air combat" situation.

The artificial intelligence, which had already defeated other AI "pilots" in simulated dogfights and collected years of experience in a matter of months, achieved a flawless victory, winning five straight matches without the human, a US Air Force F-16 pilot, ever scoring a hit.

The point of the simulated air-to-air combat scenario was to move DARPA's Air Combat Evolution program forward.

The agency said previously that it envisions "a future in which AI handles the split-second maneuvering during within-visual-range dogfights, keeping pilots safer and more effective as they orchestrate large numbers of unmanned systems into a web of overwhelming combat effects."

It is not clear how long it would take to realize the agency's vision for the future, but Snodgrass previously told Insider that he "would never bet against technological progress," especially considering "all the advancements that have occurred in the last decade, in the last hundred years."
