The RCS of the Oniks missile starts relatively high around 0.60 m² at lower frequencies, then drops significantly below 0.20 m² as the frequency increases beyond 5 GHz. It maintains a lower RCS than the Kalibr missile throughout most of the frequency range, especially after 10 GHz, where it stabilizes around 0.10 to 0.15 m². The Kalibr missile shows a higher RCS than the Oniks across all frequencies. Starting around 0.30 m², the RCS of the Kalibr fluctuates slightly but remains above the Oniks, generally staying between 0.20 and 0.35 m² throughout the frequency range.
