David Axe, China, Russia Could Make U.S. Stealth Tech Obsolete:

It’s been a pillar of the U.S. military’s approach to high-tech warfare for decades. And now, it could become obsolete in just a few years.  Stealth technology — which today gives U.S. jets the nearly unparalleled ability to slip past hostile radar — may soon be unable to keep American aircraft cloaked….

“In recent years there has been speculation that ongoing advances in radar detection and tracking will, in the near future, obviate the ability of all-aspect, low-observable aircraft such as the B-2, F-22 and F-35 Joint Strike Fighter, aka JSF, to survive inside denied airspace,” Watts writes, referring to America’s stealth bombers and fighter jets.

Stealth-killing advances include VHF and UHF radars being developed by Russia and China, and a “passive-detection” system devised by Czech researchers. The latter “uses radar, television, cellular phone and other available signals of opportunity reflected off stealthy aircraft to find and track them,” Watts explains.

These new detection systems could reverse a 30-year trend that has seen the U.S. Air Force gain an increasing advantage over enemy defenses….
