Well, that is a nice looking design.
But 48 VLS cells on this size frigate seems to be too many IMHO. I would go with 32 for sure...but 48 VLS, a full helo hanger, the main gun, eight SSMs in canisters, the FL-3000N, and the integrated mast with phased array radars would tend to push the displacement up over 5,500 tons to me.
I agree. we need a much more official source and specifications.
