Japan tried to build the best individual ships without funding the maritime infrastructure needed to replace cruisers and aircraft in a long war. After leaving the treaties, construction capacity used for heavy cruisers might instead have produced a run of fast carriers for reconnaissance and escort work without diverting the main striking carriers. A carrier could launch and recover aircraft while moving, whereas a floatplane cruiser might have to stop or rescue only the crew and lose the aircraft. That distinction mattered for a navy without the replacement depth to treat scout aircraft as expendable. Article 8 language concerning vessels up to 2,000 tons and a designed top speed of 20 knots offered another opening for calculated treaty exploitation. Japan's rule-bending and shipbuilding effort still failed to produce a sustainable intelligence system.

Japan's infrastructure limit and the fast scout-carrier alternative
The late Ibuki hull exposes the industrial and replacement gap behind Japan's cruiser-centered reconnaissance system and suggests fast scout carriers as an alternative.
