It seems to me that needing to pull over on the highway at every gas station just isn t as effective as a car that can drive from New York to Chicago with a fill up or two But that s just my US 0 02 As to the second point whether a ship is actually sunk by gunfire or if it s just damaged so severely that it s forced to scuttle doesn t matter the same result occurs On the other hand though one shouldn t conflate the effectiveness of the design with the ship s specific fate like I said somewhere else the other day I doubt a KGV or SoDak could have stood up any better to the same level of pummeling that Bis endured at her last battle
