As of my last update in January 2022, the concept of a 6th generation aircraft in the United States is still in development, with various proposals and prototypes being explored by different branches of the military, primarily the U.S. Air Force and Navy. However, specific details about these aircraft are typically classified due to their advanced nature and sensitive technology. Generally, 6th generation aircraft are expected to feature advancements in stealth, speed, range, sensors, and autonomy compared to previous generations like the F-22 and F-35. They may also incorporate advanced technologies such as directed energy weapons, hypersonic capabilities, and enhanced networking capabilities for improved situational awareness and communication.
