At 610 feet long and 15,000 tons, it’s length and displacement are almost identical to that of the USS Biloxi (CL-80)
The Cleveland class light cruisers were 10000 tonners. The length is right though.
This “destroyer” has the displacement of a Baltimore class heavy cruiser.
You know, the Army can put 6 and 8 inch guns on twenty odd ton armored vehicles put the modern Navy cannot to better than 5 inch on massive platforms.
I'll make two predicitions right now. Because of the size the Navy will re-designate them guided missile cruisers and create three new O-6 billets. And with a crew of fewer than 150 the Navy will find they have the same problem with these as with the LCS class; too much maintenance and too few bodies to do it.
