(USS) Truman Performs High Speed Rudder Test
USS Harry S. Truman Public Affairs ^ | 7/9/2012 | Mass Comm Spec Seaman Taylor DiMartino

Posted on 07/14/2012 9:58:18 AM PDT by gandalftb

USS HARRY S. TRUMAN, At Sea (NNS) -- The aircraft carrier USS Harry S. Truman (CVN 75) conducted a full power run and rudder swing checks during sea trials July 8.

The ship rolled more than 13 degrees in each direction.

"After weeks of calibrations and testing, the ship's steering was finally put to the test," said Lt. Kasey Vowell, assistant auxiliary division officer for engineering department.

Truman maxed out at 30 plus knots during the run.

America now has a ship, over a fifth of a mile long, weighs 232 million pounds, can go 35+ miles per hour to anywhere in the world, carry 90 fixed wing aircraft and helicopters......and can do a Tokyo Drift:

When I hear about all these reports about Indian and Chinese and Russian carriers, ya gotta laugh at their inferiority compared to our Navy.

The forces involved in turning a ship that large at 30 knots have to be incredible. Hats off to the engineers who made it a reality! I would have loved to have been a part of the project.

My buddy was is a plankholder on her sister ship, the USS Stennis (CVN-74).

Had the opportunity to go out to sea on a cruise with him and stand on the deck as they launched and recovered F-18s.

Very cool.

Just love how after all these years the USN can stick to these vague speed claims for our Nimitz-class carriers. It's a bit like if the USAF stopped making speed claims for their combat aircraft immediately after Chuck Yeager broke the sound barrier.

One thing I learned while in the fleet...

When you operate with one of these things, when it turns it is best to get out of its way, regardless if you have the right of way, or not...

Can’t argue with that logic at all...Or the physics...

9,600 DWT -—> 100,000 DWT

Gives new meaning to “Tin-Can” sailors...

Doesn’t sliding sideways qualify as Park Assist?

I’m guessing bow side-thrusters? Come on Swabs, splain this.

having been on a many AC (5) a 13 degree list would be a pucker factor of a plus 10 at 30 knots for ANYONE on deck. Now imagine a pilot strapped in an F-18,on deck with that same degree.Some would be in AB with tie downs still on knowing they were going overboard or as they thought so.

How would they keep the bow pointed into the turn?

My understanding is they were doing a “swing check”, a counter steer to stop the swing of the ship’s bow.

Actually, that "30+" is pretty accurate. Unless the USN is outright lying about how much SHP the turbines generate, the later Nimitz-class (which is really broken into four subclasses with each ship being fairly unique) should have a hard time reaching 31 kts.

A lot of people get hung up on the concept that "nuclear" conveys some sort of mystical superpowers on ships. In reality, the reactors are just a highly complex way of boiling water in unlimited quantities. The limitations on speed are driven more by hull form and the turbines than on the reactors (which can generate much more steam than the turbines could possibly absorb).

My interpretation of the article is that they crank the rudder to the stop in one direction, and observe that nothing unanticipated happens, then crank the rudder to the stop in the other direction, and observe that nothing unanticipated happens.

While this is happening, the rudder causes a sideways force on the stern, and only the stern, so the ship turns.

Take a toy boat, put it in a filled bathtub, and push sideways on the stern; it will turn.

Google "uss wisconsin barn door maneuver".

Carriers have twin rudders as well, but they don't have the aft hull "tunnel" that the Iowas have. So while they can execute the same maneuver, it won't be as effective as what they did on the Wisky.

Which is bringing the ship from 30kts to a dead stop in about 800 feet. (With rudder damage.)

I’m guessing they wouldn’t do that with anyone in the cats. Or at least I hope not.

Of course, with the escort group, the likelihood of such seems slim, anyways.

What did you fly?

I got a chuckle out of that, too. I bet it can do 40+kn.

The problem at higher speeds is that they outrun escorts and auxiliaries, and that they make a LOT of noise for submarine passive sonar to listen for.

I’ve know guys that served on the Indy, Forrestal, Big E, Shitty Kitty — all of them saw these carriers outrun escorts when an aircraft went in the drink.

A neighbor served on destroyers on several WestPac cruises. He was a Boiler Tech. They literally had trouble keeping station during air ops when boilers & hull needed cleaning.

Spruance-class destroyers went so fast they threw rooster tails. But sea conditions limited the practical speeds more than it did with the carriers.

In fairness, we've been at it a tad longer. Also remember that with even 1980s-1990s tech that thing is one stray missile or torp from being a hulk. Don't get me wrong--carriers are great for thumping turd-worlders who can't hit back in any meaningful way, but against a halfway modern enemy I think carriers (anybody's carriers) are this century's battleships. Impressive, expensive, and mostly obsolete. Look at systems like the Sunburn, BrahMos, or Shkval, for example, and contemplate massed attacks. Even CWIS has its limits. Actually I think they were pretty much obsolescent against a credible enemy by the late 1960's. Look at the resources we have pour into battlegroups just to protect the carrier. That's not to say they aren't useful and nice to have on hand, but I wonder about their survivability if the fur really flew against someone with modern platforms.

Yo! Larry drop that bowline and trot on over to untie that stern line in.

I remain in total awe of our carriers every since seeing the USS Forestall being fitted out in Newport News from a ten foot wooden dingy with my slightly older cousin. Back in the day when that was still possible. Aside from the sheer size of the ship, the thing that sticks in my memory was how cold it suddenly got rowing from sunlit water to the deep shadow of the moored ship, like walking into cold box.
