However, 2030s fighter pilots  will have a closer relationship with fighters. The Tempest Jet is being developed by BAE Systems in the United Kingdom, Rolls-Royce, the European missile group MDBA, and Leonardo in Italy. One feature is an artificial intelligence (AI) tool that assists human pilots when overwhelmed or under extreme stress. 4,444 sensors on the pilot's helmet  monitor brain signals and other medical data. Therefore, on consecutive flights, AI accumulates a huge database of biometric and psychometric information. This library of pilot's unique characteristics means that onboard AI can intervene and assist when a sensor indicates that it may need assistance. 
For example,  if the pilot loses consciousness due to high gravity, the AI ​​can take over. At the 
Farnborough Airshow, BAE Systems said  it would fly a demonstrator jet from the Warton facility in Lancashire to test some of these techniques by 2027. 
This aircraft will be a testbed for various digital features. Of the 60 different demonstration projects, some  will be completely software-based.  The appearance of the 
Tempest plane has matured since the first images were  released  in 2018. Among other things, its weight has been reduced and its contours slimmed down. When it finally takes to the skies,  Tempest could routinely flanked by unmanned combat drones dubbed "trailers" by the Tempest Consortium. Such progress requires the establishment of entirely new  monitoring and control systems. “We have to deal with the pace of technological change,” said John Stocker,  business development director at Tempest. "In the past, defense spending was often the driving force behind progress, and commercial technology was catching up later. Today, commercial technology is often more sophisticated," Stocker said on smartphones. We envision building a new fighter with a system that can be upgraded as easily as downloading an app. Much of the jet production is now automated. Robots on the production line exchange data with suppliers, allowing parts to be shipped quickly. As part of the project, BAE Systems and Leonardo will also collaborate with  Mitsubishi in Japan-Mitsubishi's F-X Future Fighter project has much in common with Tempest. This is a new experience for European aerospace companies, but the presence of the project in the digital realm has enabled greater cooperation with Japan. “In a digital environment, we can do these things much faster, and collaboration is much easier. We don’t carry briefcases between Tokyo and Walton,” jokes Stocker. A team of interpreters and staff fluent in  English and Japanese on deep technical issues maintains a partnership with Mitsubishi's F-X combat team. Leonardo's Edinburgh-based radar arm  also works with Mitsubishi. The general concept of radar as a swivel dish that scans ahead and reflects signals from approaching objects has been superseded by a digital search for sensor data. However, the sensor captures too much detail for the human brain to judge. That's why AI is so important in data analysis and processing.
