IJN officers continue studying Royal Navy ships

Would Japanese naval leaders visit Britain to study new Royal Navy capital ships if the alliance survived?

Yes, probably. Japanese officers would likely study aircraft carriers as well as ships such as Hood and the Nelson class.

The existing pattern of Japanese study of British naval practice would continue naturally under a durable alliance. Visits could include prominent capital ships such as Hood and the Nelson class. Carrier development would also be a likely subject of direct observation. These exchanges would transmit design ideas and operating practice alongside the alliance's strategic reassurance.
