What was once old is new again!................. What was once old is new again!.................SO, the same “US Navy Surface Warfare Dept” that designed the thing, that funded the thing, that fought for the thing, that oversaw its construction, went to sea and “tested” the thing in modest sea state storms.
Then they declared it “satisfactory” ... except for a short roll. Which really means it has terrible landing characteristics and will tire the crew at modest sea states.
Never fear. It is named for an Admiral as bad as the design.
The biggest difference between the two illustrations is that the Merrimack had thicker armor plate.
