Were the Kongo-class battlecruisers designed directly from HMS Tiger?
Short answerNo. Tiger was the benchmark and inspiration, but Kongo was redesigned around Japanese requirements rather than copied.
NotesThe Kongo class was not an official derivative or copy of HMS Tiger. Japanese designers surveyed contemporary battlecruisers and treated Tiger as the strongest visible benchmark for the qualities they wanted. They then changed the design to suit Japanese operational needs and to produce something better for their own fleet. The relationship is best understood as inspiration and competitive comparison rather than direct duplication.
