Ok. So, just show us how you will destroy the S-400 battalion with 15 F-35B only.
Send MALD-Js to light them up, then prosecute with SDB2 and JSOW.
Good plan. For a few little exeptions.
First and most important - RAF don't have anything from this stuff.
Second. MALD-J are more jamming, their recon possibility is rather low. Range of S-400 is near 400 clicks, range for MALD-J - near 475 clicks, so, you must be very careful using it to recon positions of S-400.
Third. F-35B can't bear JSOW at all, and it can bear only 2x2 SDBs in its wealons bays.
Forth: Operational range of both SBDs and JSOW is not more than 110 clicks, that is obviously inside of S-400's operational range, so, there are good chances that the most of your F-35B will be shoot down even before they will open their bays.
Fifth: SDBs are good targets for Tunguska's, so 2x2x15=60 SDBs (even if they were launched) were intercepted.
So, what will be your advice? "Call Septics, and ask them to solve your problem?"
I'd rather they call the Bureau of Ridiculous Nonsensical Military Scenarios. BRNM is a great outfit.
Sure. I said, that the duel scenarios like "isolated S-400 battalion" vs "isolated squadron of F-35B" are really uncommon and even weird.
But it is not me, who suggested to send 15 almost unarmed F-35B in the frontal attack against fully equipped and covered S-400 battalion.
