The US Air Force is pushing for a $6 billion investment in the construction of a fleet of more than 2,000 Valkyrie drones following a first-of-its-kind flight test. It was only earlier this month that Colonel Tucker Hamilton, the chief of the Department of Air Force's AI Test and Operations accelerator, announced the US Air Force successfully completed a three-hour flight test of its XQ-58A Valkyrie, a 28-foot-long experimental, stealth-focussed unmanned combat aerial vehicle. Following the test, the US Air Force is asking for $6 billion to build a fleet of up to 2,000 Valkyrie aircrafts, with each aircraft costing an estimated $3 million, which is much cheaper than a human-operated F-35 or F-22 fighter jets. The Air Force writes that the project is designed to create a "Collaborative Combat Aircraft ... capable of enhancing crewed weapon systems to achieve air superiority."
