Now might be a good moment to point out that there already IS a Submarine thread. As long as it was just for midget subs, a seperate thread is no problem. But if people are going to post ordinary subs here too, I'll be forced to close this one/merge it.
If this remark was made because of me ....
I posted only very small submarine that
I CONSIDER to be a +/- midget submarines.
(For Italian, I have put the overview with the 1930's larger subs because I have not found the views with only SLC & CA/CB midget subs)
Back to more serious things. In shipbucket, missing:
Japanese WWII:
- Kaiten-I, Kaiten-II human torpedoes; Types A, B, C, D midget submarines...
German WWII:
- Molch, Biber, Hecht, Neger, Marder midget subs or manned torpedoes
+ some others midgets subs from the cold-war era (1948-1991)
