Carlisle noted that the next generation of aircraft would be “extremely low observable” rather than simply “very low observable.” The difference is not simply the addition of electronics, networking, and cyber, he said. “There is active [stealth], passive [stealth] as well as other techniques that aid in that capability,” he explained.
