Why not, the detection of the radar is the same, be it for an F16 CJ, a Growler, Rafale or the EF. They all use the detected radar to pinpoint the location. While the US fighters usese HARM to attack the radar, which in the past was difficult when the enemy simply turned off the radar, the GPS coordinates Rafale or EF provides to Scalp / Storm Shadow will remain viable.
Scalp / Storm Shadow also have low level, terrain following capabilities to avoid radar detection and would not attack from high altitudes like HARM or JSOW right?
Especially against such highly capable SAMs, cruise missiles seems to be the only logical choice, since it's still cheaper to loose the missile, than to loose a fighter that has to get much closer to the target with LGBs, cluster bombs, or ARMs or?
The MKIs have Israeli self protection jammer so far, but not high power escort jammer like these. Russian system is on offer for India and the wingtip pods are already sold to export countries like China, but similarly Rafael is offering the Skyshild pod and DARE has developed own EW upgrades for the MKI, which reportedly include jamming pods too (most likely the Russian once, with customised systems).
