F-35 Stealth Jet Can’t Hide From Russian Radar
These problems are not secret at all. The F-35 is susceptible to detection by radars operating in the VHF bands of the spectrum. The fighter’s jamming is mostly confined to the X-band, in the sector covered by its APG-81 radar.
What the JSF does have is a jamming function—also known as “electronic attack,” or EA, in militaryese—in the radar. It also has an expendable radar decoy—BAE Systems’ ALE-70. Both are last-ditch measures to disrupt a missile engagement, not to prevent tracking.
