I'm going to disagree here. European countries are still reluctant to share DRFM based tech with Pakistan. Remember the korean fiasco where US blocked them to sell DRFM based EW to Pak? and If it is your guestimate that we got -500 then I have to say it seems improbable they have sold this particular jammer. I speculate spain must have sold this SPJ instead
