  • British H-class (Holland Type 602):

    A while ago I was very interest in Holland-type boats. So I went on a hunt for good plans (e.g. US S-class) but it was hard to obtain something useful until I wrote a mail to the Roayal Maritime Museum in London. There I could obtain really high quality scans of a group 3 h-class submarine (HMS H-51). I forgot about them for a few years but now with Corona, lock down and boredom, I rediscovered them and started making CAD models. This is where I'm at:

    Looking forward to following your progress with the H-class CAD model.

    I guess you may already be aware of some of the background information on the H-Class in the BR3034 HM submarines 1901-1930 online at the following link;

    Also Norman Friedman's book British submarines in Two World Wars has a few photo's and background information.

      Yes, I stumbled across this page. There are a few pictures around but they comparatively rare with respect to the 52 boats that were built.
