Key Point: Stealth is the fifth-generation fighter's most powerful defense.
The Air Force F-35 is using “open air” ranges and computer simulation to practice combat missions against the best Chinese and Russian-made air-defense technologies – as a way to prepare to enemy threats anticipated in the mid-2020s and beyond.
The testing is aimed at addressing the most current air defense system threats such as Russian-made systems and also focused on potential next-generation or yet-to-exist threats, Air Force officials said.
Air Force officials have explained that, looking back to 2001 when the JSF threat started, the threats were mostly European centric – Russian made SA-10s or SA-20s. Now the future threats are looking at both Russian and Chinese-made and Asian made threats.
Air Force senior leaders have explained that Russian and Chinese digital SAMS (surface-to-air-missile-systems) can change frequencies an are very agile in how they operate.
Surface threats from air defenses is a tough problem because emerging threats right now can see aircraft hundreds of miles away, service officials explained.
Furthermore, emerging and future Integrated Air Defense Systems use faster computer processors, are better networked to one-another and detect on a wider range of frequencies. These attributes, coupled with an ability to detect aircraft at further distances, make air defenses increasingly able to at times detect even stealth aircraft, in some instances, with surveillance radar.
Russian media reports have recently claimed that stealth technology is useless against their air defenses. Russian built S-300 and S-400 air defenses are believed to be among the best in the world; in addition, The National Interest has reported that Russia is now working on an S-500 system able to destroy even stealthy targets at distances up to 125 miles.
While the Air Force aims to prepare for the unlikely contingency of a potential engagement with near-peer rivals such as Russia or China, Air Force planners recognize that there is much more concern about having to confront an adversary which has purchased air-defense technology from the Russians or Chinese. Air Force F-35 developers emphasize that, while there is no particular conflict expected with any given specific country, the service wants to be ready for any contingency.
