RCS

RCS, or Radar Cross-Section, measures how detectable an object, like an aircraft, is by radar; a smaller RCS means the object is harder for radar to see.

TECHNICAL DEFINITION

Radar Cross-Section (RCS) is a quantitative measure of an object's detectability by radar, indicating the equivalent area of a perfect metallic sphere that would reflect the same amount of radar energy back to the receiver, and is a critical parameter in military aviation for designing stealth aircraft to minimize their radar signature.

BACKGROUND

In France, the Operational Defence of the Territory is according to the Code of Defence, the participation of the French Armed Forces "To maintain the freedom and continuity of action of the Government, as well as to safeguard the organs essential to the defense of the nation."
