The ultimate torpedobeat ship

Very impressive, thanks for sharing. Anyone else check for extra gaps in the crew on deck afterwards? No man overs in the manoeuvre!

Now try that in an Iowa!

Only the USS Wisconsin has experimented with this type of stop called "Closing the Barn Doors".

A normal full "Crash Back" stop keeps the rudders amidships but the propellers are reversed from full flank ahead to full flank reverse. It takes the ship about a mile to come to a stop before going in reverse again. I was riding the Missouri at the time we tested this out and it is amazing how quiet the machinery spaces suddenly get and start up again.

The inboard shafts 2 & 3 on an Iowa class are built into large skegs supporting the 5-bladed propellers. The outboard shafts 1 & 4 support the 4-bladed propellers by struts.

But the rudders are almost in line with the skegs for props 2 & 3 and those skegs form a virtual tunnel underneath the ship allowing for lots of water to pass through.

The Proceedings had an article on this back in the 80's of the Wisconsin testing the Barn Door stop. By turning over the rudders to local control (in the steering gear rooms themselves) they could be operated independantly and turned inboard to each other to close off that tunnel of water.

This also including reversing the props as well.

The results were shocking and often messy as anything not tied down wound up on the deck or against the forward bulkhead. In one test, they had a crewman throw a piece of wood off the bow as the "Barn Door Stop" was ordered. When she came to a stop, the piece of wood was almost abreast of Turret III.

That's stopping a 57,000 ton Battleship in about 600 feet.

When we reactivated the Wisconsin in the 1980's, there was an Insurv item from sea trials that the rudders vibrated and were a tad loose. When she was dry docked in Philadelphia, I was party chief of a shipcheck team for other modifications. But I was also given a huge roll of rudder drawings (about a foot in diameter) to deliver to Philly.

After relating my just by chance reading of that Proceedings article, they then knew what they had to do to tighten the rudders back "up" again (literally "up" by about an inch).

Naturally, "Closing the Barn Doors" became high on the list of things NOT to do with a Battleship.

Flashing those citadel areas :)

"I left the oven on!"

Watching a Nimitz class carrier doing it is even more impressive/scary

[u/ShuggieHamster]

obviously the lower deck on the starboard side needed a quick rinse

Look at the size of that flag. Totally need bigger flags in WoWs. Just look at that puny Hipper flag and compare.

I love how the ensign unfurled as it completed its turn. Brought a tear to my eye...
