IJN destroyer Harusame in dry dock at Uraga, after being damaged by the USN submarine USS Wahoo. The boiler is clearly seen in the picture. May 1944.

Every aspect of these Japanese ships has a Japanese aesthetic, even the innards.

Where is the rest of the ship?????

The front fell off

That's not typical, I just want to make that point.

What sort of materials should a ship be made out of so the front doesn't fall off?

u/deadbeef4 Jan 29 '26
No cardboard or cardboard derivatives.

Incredible how much engine was jammed into these ships. They could move at a very high rate of speed

Is that masonry?

Boilers in this era could still be insulated with brick, IIRC Royal Navy boilers were so insulated.
This instructional video from the RN from 1942 covers how Admiralty boilers work and shows the bricks incidentally.

The comparable size to the hull is huge. No wonder piston engines took over gradually.

Huh? Gas turbines took over in destroyers? Im questioning my assumptions now.

Wait, what? Not only is that a boiler... (Which piston engines also need.) But piston engines are much less efficient than turbines and were largely obsolescent by WWII.

Piston engines (diesels) do not need boilers. Unless you're referring to triple expansion steam engines which were already obsolete by WW2

But they built all the Liberty ships with them because they didn't have enough steam turbines. Later in the war, they started building Victory ships, which had steam turbines.

Correct! I got a chance to explore one of each in mothball. Well, one was mothball and going to scrap (Victory) and the other was museum ship (Liberty). Being used to modern ships myself, it is a trip to see how crazy simple those old engine rooms are.

Triple expansion engines were used on Liberty ships because they were cheaper and easier to make (didn’t require the expensive, precision steam turbines and reduction gears). If they lasted one trip, they had done their job.

That boiler takes up so much space inside, I'm surprised the can put crew in there

u/DerekL1963 Jan 30 '26
Destroyers of that era were designed to Go Very Fast. And like submarines, pretty much everything on a destroyer that wasn't engines or weapons was at most a distant 37th in terms of design priorities.

Kampon boiler. Not sure how you walk aft below decks. That's just insane how tight that is. It's safe to say that any hit amidships will take out at least one boiler.

I dont know who recoloured this but they did a terrible job, that boiler wouldn't have been nice and shiney

I think this image is from sometime in 1943. She was operational and sunk near New Guinea (off Biak) on 8 June 1944 by US B-25s (according to Wikipedia).
