While the size of the US Air Force may be shrinking, it is constantly changing and developing new systems and countermeasures to threats developed by other nations. The US Air Force is innovating at a lightning pace spurred on by developments in the war in Ukraine and the specter of military conflict in the Pacific. Some innovations are high-profile (such as the development of the sixth-gen NGAD fighter), while others exist in the software domain (like AI and Cyberwar). Drones ranging from the threat of massed FPV drones to advanced loyal wingman drones are also driving the innovation of the Air Force.
