Yes, this is going to happen.
For decades since the bomber became operational in 1997, the Northrop Grumman B-2 Spirit stealth bomber has been effectively invulnerable to enemy air defenses. However, America’s enemies are starting to learn how to counter stealth aircraft, but the technology remains unproven as of yet. Various approaches have been tried to counter stealth aircraft including the use of low frequency radar, infrared, ultraviolet, bistatic and multistatic radars. Thus far, infrared search and track (IRST) and low frequency radar have shown the most amount of promise of being able to generate a weapons quality track on a stealth aircraft. Indeed, the only technology the U.S. government is willing to talk about to shoot down stealth aircraft is IRST technology.
The fact of the matter is that the B-2 will eventually lose its ability to penetrate enemy airspace. “The technology on which they were designed with respect to signature management. . . is ‘80s vintage,” then Air Force chief of staff Gen. Norton Schwartz told the House Armed Services Committee on Feb. 28, 2012. “And the reality is that the B-2 over time is going to become less survivable in contested airspace.”
The first and most obvious way to attempt to detect and track a stealth aircraft its to increase the power and processing power of a radar system as a Naval Postgraduate School paper by Serdar Cadirci describes:
