imperial japanese navy

Hello there, I was browsing navweapons and came across a design mentioned in passing within the article about the Japanese 100/65. Apparently, there was an experimental 140/80 gun tested in 1933. I was hoping someone here had more information on the gun.

From Macintyre, Donald. Wings of Neptune: The Story of Naval Aviation (The Evolution of Naval Power Book 2) (p. 106). Sapere Books. Kindle Edition. In the section where the attack on Prince of Wales and Repulse is discussed, he mentions that the night before, 'The searching aircraft found and...

This "design" apparently did exist as a specification for the Maru 6 program -- but since the plan was pretty much shelved with the defeat at Midway, nothing came of it. Assumedly, most (if not all) records of its existence were destroyed. Certainly, no official drawings survived (if they ever...

Hello, i'm looking to experimental projects for supplying isolated japanese garrisons in ww2. For example: Special containers used with submarines. Unkato, Tokugata Unkato, Unpoto. Special waterproof landing craft on after deck of submarines. How the supply were stoked on the deck ? With a net...

A detailed description of the Torpedo Protection System for this ship is held by the University of Tokyo and has been digitised. I have downloaded, and uploaded here, the description and the diagram of this system. It goes without saying that the presence of this document in Japan is a very...

Something about Super-A Cruisers before Maru-5 Project. Source: 早川幸夫，スーパー・クルーザー「超甲巡」覇王伝説，月刊《丸》，2013年5月号 (Monthly "Maru", May 2013). The author stated that in a 1934 document named "Required National Defense Force from Treaty-Break to 1940" (条約決裂後ノ昭和十五年度ニオケル国防所要兵力表), that IJN's original plan...

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...

Here I gathered all the various cruiser designs and projects proposed for the Imperial Japanese Navy Protected Cruisers: Not found any so far except the cancelled sister ships of the Unebi and Tone classes Light Cruisers: Design C-19 (1912) - A primary mine-layer cruiser design offered before...

Time frame should cover gearing-up to the Pacific war and the war itself. What should've they specified differently for industry to make vs. what was made historically, in order to put up a better fight against the 'West', or mostly against the USN/USMC/USAAF? Not to make a host of designs that...

Question - Had the USN known the true characteristics of the IJN Yamato Class at the onset of war, what, if anything, would have changed with regards to USN battleship design and production? Would have carrier production suffered and the remaining Iowa Class been completed? Would have the...

Hi again after long while. I recently finished some new 3d pieces so I thought I may drop these by. Below my latest (and some older) artwork for IJN's Mizuno Shinryū II. If you feel like it, look up more on https://www.artstation.com/senshi-isamu or https://www.deviantart.com/senshi-isamu. Cheers!
