Both stealth and non-stealth planes can be easily detected within the range of a satellite or early warning system, with this information being fed to fighter jets through an integrated detection and fire system, effectively extending the detection range.
The stealth jet's detection can be facilitated by anti-stealth radar systems. Additionally, the stealth material's high maintenance requirements and tendency to deteriorate over time, particularly after repeated use, make it more susceptible to detection. Furthermore, the rarity of the required materials used for maintenance can also contribute to its detectability.
