Portside Aft Steering Gear Compartment on the Battleship Iowa

Some of the tour today covered things I'd already seen and wrote about, like the Barbershop, Brig, and Laundry areas, so I won't go over them again.

We started in the Crew's Mess, as the passageway we would take was off the Museum Store.

While the steering gear compartment is armored, it's outside of the "Armored Citadel", which runs from just forward of the #1 turret, to just aft of the #3 turret.

The blue painted area shown below is the top of the aft end of the armor.

As you can see, it's really thick:




After we went down one deck, below this first armored deck, we passed by a hatch leading down to the 4th deck. The stainless steel door to the right leads in to one of the "reefer" areas where refrigerated foods were stored. If you look carefuly at the ladder going down, you'll see some "flaps" mounted on the sides of it. When these were moved to cover the steps, it made them into a ramp so boxes could be easily slid up and down the ladder.

Pretty clever:




Here's another ladder going down to the refer area, and still another hatch under that, with grating on the bottom:




Now, the good stuff!

Getting closer:





One more armored hatch to go through, and we're there:




This is the control panel for running all the pumps and servos, and a place-of-last-resort to steer the ship from.

 Notice the two bronze mounts in the picture. There are where the handwheels were located to manually (with hydraulic assist, of course) steer the ship.

The closer of the two got cut off in the picture, but in the one further away, at the bottom of the bronze mount, you can see a stub shaft with a white tag hanging on it. These were the stubs the wheels attached to.

The wheels were removed for some reason, and are "MIA" for the time being:





How do you know you're on the Port side? Well, besides the yellow painted designator with the frame number, there's a red stripe painted on the wall, red just like the Port navigation lights on the ship.

And notice the rows of rivets overhead. This was the top of the localized armored box the steering gear is in:





Rudder position indicator:




Aft end of the hydraulic rams that move the rudder. The large round plate in the left foreground is the top post of the actual rudder, and the "dogbones" on either side connect to the rams:

Another view looking forward:





The hydraulic diagram of the system. Sorry for the flash hot-spot:





And a drawing listing all the lube points, and what type of grease/lube to use:





So, that was today's behind-the-scenes tour. While we were sitting in the barbershop, the question of "Turret Tours" was brought up. Turret #2, where the accident occurred, is absolutely OFF LIMITS, as it's a memorial to those who died in it. Current plans are being discussed for turret #3, and include putting in a plexiglas "bubble", where people could at least climb partly in to the turret, and look around, and a Virtual Tour" of the turret, being put together by one of our volunteers who's extremely good at taking panoramic photos, and stitching them together, giving views similar to what The Smithsonian does for some of it's aircraft interiors.

I've seen his panoramas of the radio room, and some of the superstructure areas, and their amazing.

Actual tours of the turret, and it's inclusion on the tour route, will require getting all the HAZMAT items out of the turret, and cleaning it up and painting the inside.

Hang on, it's on the "TODO" list for this year!

  1. Fantastic. Really gives you some ideas as to the sheer size and bulk of that ship.

    1. Yeah, but even though she's 887' long, and 108' wide, there's not really a lot of room inside her.

      Berthing spaces (sleeping areas for the landlubbers) are *everywhere*, even down on the third deck where we were.

    1. I'm on her at least two days a week.

      As I get the behind-the-scenes tours, I'll post more.

  3. Yes, that's every bit as massive as I expected. "Aft steering" on my tin can was a motor about the size of large-block V8.

    Thank you for letting us see this much-more-impressive setup. :)

    1. I would have taken more pictures, but the tour leader was only taking four people at a time, and my wife and I were in the last group, so we were pressed for time.

  4. Nice! Thanks!!! And that does give one a good idea of the TRUE size of the ship!
