It sounds as if the Russians and the Chinese are blowing smoke here.Since the U.S. has had stealthy aircraft since the 1980’s.At that time the Russians had radars that were not as good as an American radar and even if the Russians improved their radar capabilities the U.S. has had the time and experience to update its stealth aircraft capabilities.
They are not blowing smoke. What they look for is the absence of radio signals. Stealth tends to be a black hole for all radio emmissions, so... instead of looking for radio reflections (looking for a white dot on a grey field) you look for a lack of ambient radio signals (looking for a black dot on a grey field).
F117A was shot down by using obsolete 1950s radar.
And this obsolete radar made stealth gimmick obsolete overnight.
For some reason Chicoms decided to make their own copy through R&D (reverse engineer and Duplicate).
A quiz question for aviation aficionados:
F-35 can be considered stealth only when 2 internal weapon bays are used and no external weapons attached to the hardpoints.
When using only 2 internal weapon bays F-35s can be easily outgunned.When using under-wing missiles it can be out-maneuvered.
True or false?
