Security,
We have some answers for you.
Physics dictate that a tactical fighter-sized stealth aircraft must be optimized to defeat higher-frequency bands such the C, X and Ku bands, which are used by fire control radars to produce a high-resolution track. Industry, Air Force and Navy officials all agree that there is a “step change” in an LO aircraft’s signature once the frequency wavelength exceeds a certain threshold and causes a resonant effect—which generally occurs at the top part of the...
