It is the only FAF mission designed to be won with navy, but the last eastern Seraphim is unreachable with 128-range battleships. I suggest to modify the terrain of his base for the mission to be beatable with pure navy.
Red Flag mission changes
@waffelznoob Can't we have 1 mission where navi could win on its own? Right now, it's this: "Water mission! I will be building navi the entire game. Great, can't finish the mission."
