Is this the technology that will define 6th generation fighters?

DARPA’s effort to incorporate Active Flow Control in military aircraft could eliminate the need for moving flight control surfaces, and while that might not sound like very groundbreaking technology, it might be the biggest shift in aircraft design since the inception of stealth more than a half-century ago.
The Control of Revolutionary Aircraft with Novel Effectors (CRANE) program may carry a long and innocuous name, but the effort may yield the most difficult to detect stealth fighters and bombers ever made. In fact, fielding a jet with no external control surfaces would be such a radical departure from existing fighter design that it would almost certainly warrant a new generational moniker–making such a hypothetical aircraft a good bet for the race to develop the first 6th generation fighter.
