Senpyosen: Japanese Warfare Standard Ship & Other Japanese Cargo ships used during WW2

戦時標準船 (戦標船)

Warfare Standard Ship (Senpyo-sen)

Quote

 

3cMm0iY.jpgThe Largest Warfare Standard Ship, 1TL-class Oil Tanker

Japanese Warships are very well-known, but cargo ships are little-known. But we should not forgot it...

These classes of ships are built during WW2 for math-production, and there are 4 waves.

Its engine performance is very low, and some of them using single bottom. Because of it when aground and it broke.

In total one thousand ships are built.

Spoiler

 

K: Koseki (鉱石, Ore)

TL: Tanker, Large

TM: Tanker, Medium

TS: Tanker, Small

ET: Type E cargo ship based Tanker

 

 

第1次戦時標準船 (1st Wave)

These ship are designed for postwar business management, so it have good performance but its inferior to mass productivity.

1A~1F class cargo ship are same as 平時標準船 (Peacetime Standard Ship). Ore Bulker and Oil Tankers are small changes of under construction ships.

第2次戦時標準船 (2nd Wave)

In the end of the war, 3/4 of Japanese ship are these class. But they are too dangerous: they have only single bottom and too low engine power, so GHQ bun to use them.

When design these ships, Japanese lost maritime authority so they design its service life is engine: 1 year, hull: 3 year. There nickname is "轟沈型"/"sink within minutes-class".

The 1TL looks like it'd be fairly decent, as far as its firepower and speed go. There are two main downsides that I can see - the large size and the slow muzzle velocity of the 20cm gun. On the other hand, large size probably means a lot of crew, so there's that.

 

The 1TL is the most likely to be added as playable, since the others are not even armed. I could see all of them being added as AI targets though, in case Gaijin ever wants to expand on that.

If add playable, I think 防空基幹船 is more better.

https://ja.m.wikipedia.org/wiki/防空基幹船

Also, Standard ships in 1st wave are built early of the war, so they sunk before reinforcing defensive equipment, but wave 2 or other have same weapons as 1TL class.

 

 

edit

1TL/2TL class modifies to Toku-1TL /Toku-2TL class aircraft carrier.

Toku-1TL is for Navy to support their fleet, and Toku-2TL is for Army to escort convoy.

Not sure if you have seen this already, but the report Provisions For Military Conversion of Japanese Merchant Ships S-82(N) may be useful, especially when it comes to modeling many of these ships.

 

Here are some of the blueprint pictures of the ships included in the document:
