The X-62A VISTA first flew in April 1992 as the NF-16D, a General Dynamics and Calspan variable-stability testbed. Thirty-four years later the same airframe flew 27 autonomous intercepts under the control of a Lockheed Martin AI agent, using live infrared data from a Legion Pod to find and close on a T-38 Talon. Lockheed disclosed the results on 4 August.
A modified F-16 flew under the control of artificial intelligence during a US Air Force and DARPA trial. An important step for the US military, even though the "autonomous pilot" remains closely monitored and still far from being sent alone to combat (and so much the better!).
