Ship project history: Project A-127, designed by Y. Hiraga: enlarged Nagato with flush deck, additional turret, 610mm TTs and improved protection scheme.
Ship protection: 15°inclined main belt had 280mm thickness between barbettes, tapering to 76mm at lower edge. Upper part of anti-torpedo longitudinal bulkhead extended up to main deck and served as 30mm splinter bulkhead. Main belt was closed by 330-254mm fore and 254mm aft bulkheads abreast end barbettes. Hull outside end barbettes was protected by 229mm belt tapered to 76mm at lower edge. Upper 229mm belt extended from main belt to upper deck between end barbettes. It was closed by 229mm angled bulkheads. Lower casemate had 152mm armor. Upper casemate had only 25-19mm protection. Flat main 160-102mm deck connected with upper edge of main belt. Lower (splinter) deck had 38mm thickness in flat part and connected with lower edge of main belt by 102-51mm slopes. Deck over lower casemate was 38-25mm. Turrets had 356mm faces, 203mm sides and rears and 190mm crowns. CT had 356mm sides and 76mm roof. Underwater protection was 6.5m deep and content 76mm longitudinal bulkhead.
Naval service: Ships had to be demolished under terms of Washington conference but later Kaga was rebuilt as aircraft carrier, when planned to rebuilding Amagi was destroyed by earthquake.
