Maverick’s next wingman could be a drone.
In the movies, fighter pilots are depicted as highly trained military aviators with the skills and experience to defeat adversaries in thrilling aerial dogfights.

New technologies, though, are set to redefine what it means to be a “Top Gun,” as algorithms, data and machines take on a bigger role in the cockpit — changes hinted at in “Top Gun: Maverick.”

“A lot of people talk about, you know, the way of the future, possibly taking the pilot out of the aircraft,” said 1st Lt. Walker Gall, an F-35 pilot with the U.S. 48th Fighter Wing based at RAF Lakenheath in England. “That’s definitely not something that any of us look forward to.”

“I’d like to keep my job as long as possible, but I mean, it’s hard to argue with newer and newer technology,” he said. “And if that’s the way of the future, that’s what it is. But I’m just here to enjoy it while I can.”

The future for fighter pilots was on display this week at the Farnborough International Airshow near London, one of the world’s biggest aviation, defense and aerospace expos.

Defense contractors outlined how artificial intelligence and other technologies will be used in the newest warplanes as global military delegations browsed mockups of missiles, drones and fighter jets. At stake are many billions of dollars as countries update military fleets or pump up defense procurement budgets amid rising geopolitical tensions.

The original “Top Gun” movie released in 1986 follows Tom Cruise’s hot-shot Navy pilot, Pete “Maverick” Mitchell, through fighter weapons training school. In the sequel, an aging Maverick, now a test pilot, learns the top secret hypersonic plane he’s working on is being canceled so the funding can be used for a pilotless drone program.

It’s a debate that’s been playing out for years in the real world. Drones have been used extensively in the war between Russia and Ukraine and other modern conflicts, raising the question of just how much need there is for human pilots to fly expensive fighter jets and other aircraft — or whether unmanned aerial vehicles could do the job.

At the Farnborough show, experts said the future of air warfare is likely to be manned and unmanned aircraft working together.
One day, fighter pilots will “have a drone aircraft that’s flying as a loyal wingman” under their control, said Jon Norman, a vice president at Raytheon Technologies Corp.’s missile and defense business.

Norman, a retired U.S. Air Force pilot, said he used to complain about drones controlled from the ground that got in his way when he was flying fighter jets.

The latest communications systems let fighters, drones and other aircraft talk to each other, he said.

Technology has already removed the need for a second person to sit in the backseat to work the radar — a role portrayed in the original “Top Gun” movie by the character Goose.

It will continue to play a bigger role in the cockpit, Raytheon executives said. Artificial intelligence will analyze reams of data from sensors placed on planes, drones, the ground or missiles flying through the air to give pilots in the sky and commanders back at headquarters a better sense of the battlefield.

In future battles, AI might allow a pilot to send an armed drone close to an enemy position “and have them just fire at will,” Norman added.

But it’s too soon to write an epitaph for the pilot.

“If we had had this conversation 20 years ago, almost everyone was certain that some (drones) would be serving in a combat aircraft replacement role. That simply hasn’t happened,” said Richard Aboulafia, managing director at consultancy AeroDynamic Advisory.

Nowadays, he said, drones mainly support manned military aircraft, which “allows them to get out there with a greater combat aircraft punch.”

There was speculation that the F-35 fighter, which went into operation in 2015, would be the last manned fighter jet, said Gareth Jennings, aviation editor at defense intelligence provider Janes. “But no one says that anymore.”
The F-35, built by Lockheed Martin Corp., is a stealthy fighter part of today’s generation of warplanes. There is a next generation of fighter jets in the concept stages offering even more high-tech advances, including potentially pilotless versions, but they won’t arrive before the next decade at the earliest.

Gall, who recently graduated from fighter pilot training school, said the F-35 is easy to fly and that technology would likely make its successors even easier. But he stressed that the fighter pilot’s role would remain intense.

Even if that role isn’t going away anytime soon, the Pentagon is working on transforming it.

The Air Combat Evolution program, run by the Pentagon’s DARPA research agency, is working on incorporating artificial intelligence into warfighting, including designing a plane that can fly itself in a dogfight.

The program has already carried out a live simulation of air combat, pitting a virtual plane piloted by an AI agent against a human pilot. If all goes well, researchers plan to carry out a live dogfight with AI-enabled planes by 2024.

Experts, though, are skeptical pilots will be eliminated from the cockpit in the near future.

“I don’t think we’ll be at the stage of not needing fighter pilots for a few decades yet,” said Jennings, the aviation editor. “Unmanned technology and the public willingness to accept not having a human in the loop are just not there, and won’t be for at least another 30 years or so.”

China on Sunday launched the second of three modules to its permanent space station, in one of the final missions needed to complete the orbiting outpost by year’s end.
A live feed on state broadcaster CCTV showed the 23-ton Wentian (“Quest for the Heavens”) laboratory module launching on the back of China’s most powerful rocket, the Long March 5B, at 2:22 p.m. (0622 GMT) from the Wenchang Space Launch Center on the southern island of Hainan.
Space agency staff, seen on the live feed observing the progress of the launch from a control room, cheered and applauded when the Wentian separated from the rocket about 10 minutes after the launch.
The launch was “a complete success”, CCTV reported shortly after.
China began constructing the space station in April 2021 with the launch of the Tianhe module, the main living quarters, in the first of 11 crewed and uncrewed missions in the undertaking.
The Wentian lab module, 17.9 meters long, will be where astronauts can carry out scientific experiments, along with the other lab module yet to be launched – Mengtian (“Dreaming of the Heavens”).
Wentian features an airlock cabin that is to be the main exit-entry point for extravehicular activities when the station is completed.
It will also serve as short-term living quarters for astronauts during crew rotations on the station, designed for long-term accommodation of just three astronauts.
Mengtian is expected to be launched in October and, like Wentian, is to dock with Tianhe, forming a T-shaped structure.
The completion of the structure, about a fifth of the International Space Station (ISS) by mass, is a source of pride among ordinary Chinese people and will cap President Xi Jinping’s 10 years as leader of China’s ruling Communist Party.
On board the space station are Shenzhou-14 mission commander Chen Dong and teammates Liu Yang and Cai Xuzhe. They are slated to return to Earth in December with the arrival of the Shenzhou-15 crew.

Virtually all the contiguous United States experienced above normal temperatures in the past week, with more dangerously hot weather forecast.
The U.S. heat wave followed record heat that killed hundreds if not thousands of people and sparked wildfires in Europe.
Following is an explanation of what is causing the heat waves, according to scientists.
What is a heat wave?
A heat wave has no single scientific definition. Depending on the climate of a region, it can be determined by a certain number of days above a specific temperature or percentile of the norm.
Arctic warming and jet stream migration
The Arctic is warming three to four times faster than the globe as a whole, meaning there is ever less difference between northern temperatures and those closer to the equator.
That is resulting in swings in the North Atlantic jet stream, which in turn leads to extreme weather events like heat waves and floods, according to Jennifer Francis, senior scientist at the Woodwell Climate Research Center.
Heat domes
Warmer oceans contribute to heat domes, which trap heat over large geographical areas. This weekend the heat dome is stretching from the southern plains of the Oklahoma/Arkansas area all the way to the eastern seaboard, according to the U.S. Weather Prediction Center.
Scientists have found the main cause of heat domes is a strong change in ocean temperatures from west to east in the tropical Pacific Ocean during the preceding winter.
“As prevailing winds move the hot air east, the northern shifts of the jet stream trap the air and move it toward land, where it sinks, resulting in heat waves,” the U.S. National Oceanic and Atmospheric Administration says on its website.
El Niño and La Niña
Every few years, the climate patterns known as El Niño and, less frequently, La Niña occur. El Niño brings warm water from the equatorial Pacific Ocean up to the western coast of North America, and La Niña brings colder water.
At present, La Niña is in effect. Because summer temperatures trend lower during La Niña, climate scientists are concerned about what a serious heat wave would look like during the next El Niño, when even hotter summer weather could be expected.
Human-influenced climate change
Climate change caused by the burning of fossil fuels is a global phenomenon that is certainly playing a role in what the United States is experiencing, scientists say.
“Climate change is making extreme and unprecedented heat events both more intense and more common, pretty much universally throughout the world,” said Daniel Swain, climate scientist at UCLA.
“Heat waves are probably the most underestimated type of potential disaster because they routinely kill a lot of people. And we just don’t hear about it because it doesn’t kill them in, to put it bluntly, sufficiently dramatic ways. There aren’t bodies on the street.”
Francis, of the Woodwell Center, said with climate change the world is seeing changing wind patterns and weather systems “in ways that make these heat waves, like we’re seeing right now, more intense, more persistent, and cover areas that just aren’t used to having heat waves.”
Alex Ruane, researcher at NASA’s Goddard Institute for Space Studies, said as the world warms, “it takes less of a natural anomaly to push us into the extreme heat categories. Because we’re closer to those thresholds, it’s more likely that you’ll get more than one heat wave at the same time. We’re seeing this in the United States.”
