If you have the most data on the FHE-400, might as well stick to that one.
Of course if you based it on the Supramar 250, you would have had the missiles on the ship.

Well FHE-400 being an unarmed prototype. The production version was intended for ASW use with towed sonar array and most likely asroc. FHE-400 using more basic foil configuration without predictors.
