Regulus and Ram were a 2 ship class of minelayers under construction in the Dutch east indies when the Japanese took over the colony. They were renamed Nankai and Nanshin, Nankai was completed as a powerful gunboat, but Nanshin was less heavily armed and not completed. Small note about the link...

yeah I bet you can't guess The I-351 and her sister sub the I-352 were laid down as flying boat tender submarines, but converted during construction to tanker subs. Original specifications, design docs and illustrations itt

The Ha-101 class submarines were laid down as transport submarines, but during construction were converted into tanker submarines, small submarine motherships/tenders, and radar picket subs. Any specifications or illustrations of the intended original design would be bussin...

The Ohama and her sister ship Okashi were laid down as target ships, successors to the Hakachi. Ohama was completed as an escort vessel, and Ohashi collided with Yamashio Maru and sunk before completion, but would have been given the same treatment. I can't find any illustrations of their...

The Satsuma class as laid down was intended to mount 12 12 inch guns, with 4 on the centerline and 5 on either side, in a total of 4 twin and 4 single gun turrets. Due to budget issues that the link goes into, the ships got redesigned as semi-dreadnoughts. I can't find any illustrations of the...

This is not an unbuilt project, but it is an enigmatic mystery that perhaps members here might be able to add more to. The Volta was a 19-ton electric-powered submarine armed with two 12in torpedo tubes, built by Rennie Forrestt Shipbuilding, Engineering & Drydock Co. Ltd at Wivenhoe, Essex...

For some time I've already made these drawings just not yet posted here. You can now see how the Tosa / Kaga class battleships evolved from an Improved Nagato to as laid down as a 5 turreted similar speed slightly larger battleship. Let us begin: Fast Nagato series: A-115...

I like japanese paintings, and I like WW2 aviation too, so what is better of japanese paintings about aircraft, painted during WW2? After a little search, I found the following, some taken from here: Zero fighter ready to take off from an aircraft carrier. It is also on the cover of this book...

Hi. From the Research Topics - Designations Systems Forum part: Are there any further data/infos/pics in japanese service available on these IJN experimental aircraft? Yours tom! ;)
