correct, though im not so sure about it having a radar mode applicable to it, i see some kind of sea search mode being thrown around a lot in online discussion but haven't been able to find any info on it myself
would like to add something to this
Spain had plenty of assets for anti-shipping, maritime patrol and ASW in both the airforce and navy by the time the F1M upgrade started being developed, not just the hornet, aircraft like the P-3, the SH-60B and AB-212ASW are the first that come to mind
It doesn't make sense to add this kind of capability to a stopgap upgrade of a plane the airforce wanted to get rid of as soon as possible, especially for weapons the airforce would never even bother to buy
