What was the best warship in service when this stream aired?
Short answerThere was no universal best; Danish and Italian designs stood out because they matched their own navies' needs particularly well.
NotesNo current warship is universally superior because different navies need different capabilities. The comparison is more useful when it asks which service has designed ships that best fit its own requirements. Danish and Italian designs receive praise on that basis, while Russian ships are described as more limited by technology. A ship should be judged against the missions and support system of the navy that must operate it.
