I guess it's whether the sonar dome proportions, shape and size modelled actually looks like that on the actual ship. The dome shown on the Fujimi & Hasegawa kits are gigantic for the JS Hyuga and Ise. I've a model of the later JS Kaga and the dome on that model is considerably smaller and it's size and shape resembles the USN 26/53 style domes.
Am always interested in the operating capabilities of overseas navy's sonars compared to those published for the USN.
Just wanting to make sure my hobby models look as accurate as possible.
