These technologies which will be able to detect an F35 from 2030

Since the use of the F117 during the first Gulf War in 1991, stealth is considered to be the essential characteristic of a combat aircraft, to be able to face the modern anti-aircraft defenses of a determined adversary . And Lieutenant Colonel Zelko's plane, shot down by an S-175 missile battery (NATO classification SA-3), when it had just opened its munition flap on March 27, 1999 did not change much . Stealth had become the Holy Grail of aircraft manufacturers and world air staffs. And several programs based on this characteristic were developed, in the field of combat aircraft such as the American F22 and F35, the Russian Su57 or the Chinese J20, as well as strategic bombers, ranging from the B2 Spirit and the American B21 raider to future HH- 20 Chinese and Russian Pak-DA.

As always, as technologies to reduce an aircraft's radar equivalent area continued to advance, others developed technologies to counter them, and to detect these devices despite their supposed radar invisibility cloak. Empirical at first, these new counter stealth technologies are now reaching levels of reliability making their operational use possible. In 2030, many of them will actually be in service, making passive stealth used on devices like the F35, Su57 or J20, if not obsolete, in any case much less efficient.

2020: multistatism

Multistatism is based on the physical separation of the radar transmitter and receiver. Indeed, a stealth plane is never really stealthy, and when it approaches below a certain distance from a radar, it ends up being detected. Thus, for the F35A, public data estimates that an A-3 Sentry would be able to detect it at a distance of 30 km, while it is able to detect a Su-30 or an F-15 beyond 200 km.

The stealth of the F35 will not be fully effective for a few more years, after which new detection technologies will neutralize the benefits.
