It’s also an order of magnitude more effective than Russia’s KH-101/55 and Kalibre cruise missiles that require at least 10 missiles to possibly strike 1 target. By the time the Storm Shadow performs its popup maneuver to verify the target, it’s too late for air defense. By all appearances, Russian air defenses would have little chance against the west’s newer/stealthier cruise missiles like the JASSM.
Shoot down a JASSM?
Russian AD hasn't been able to shoot down a TU-141 (picture below).
