Yep..lets just stuff all of those guns, missiles, and radar and sonar suites into a canoe and expect it to handle and wear like a battle cruiser. That’s what cheaping out will do for you...
The USN. This information was undoubtedly classified before being cleared by the USN to Jane’s for public consumption.
Above my pay grade (and not even remotely in my field, anyway) ... but I'm guessing that they figured they couldn't keep it under wraps, so why waste time trying?
5. How much is this engineering design flaw going to cost the taxpayers to fix versus how much the engineers who designed it will have to pay? There should be consequences when "PE" is added after your name....
I wonder if this is a consequence of placing so much importance on “stealth” in the design.
Seaworthiness should come first.
On a tower crane, if you drill a 1/4” hole in a structural member to thoughtlessly mount a piece of secondary gear or equipement, you voided the design integrety of the engineered product.
On these big ships, where the overall structure is designed by an entire team of engineers, it isn’t possible to design for every concievable combination of loads imposed by the decades of usage issues. As AppyPappy points out, the ships are commissioned, and often later fitted, with all sorts of equipment based upon the usage and mission for the “platform.” Even with good planning and analysis, various combinations of loads, all balanced against a whole group of forces, primary and secondary, that the ship is subjected to under usage make for unique issues during the life of the ship that the original superstructure engineer can’t always anticipate and that the Navy or user won’t want be be restricted in attempting.
I don’t actually think that modifications after partial problems aren’t that unique — it happens with aircraft all the time. I think the issue here is that it is occuring across an entire class of ships.
‘The navy (USN) has admitted that many of the 51 ships currently in service are buckling under the stress of higher-than-anticipated loads at sea.
The impact of rough-sea slamming on the bow has led to warping of main transverse bulkhead beams and some of the cribbing, a source said. ‘
The Gridley was on its sea trials, and is cited as an example for all 51 of the Arleigh Burke class?
Incorrect.
IIRC, the Arleigh-Burkes at 8000 tons,
more like asking for the meager capability of a destroyer,
from a cruiser.
“...Ma bearins...Ma poor bearins!”
During WWII, as ships were refitted to better fit the battle requirements, destroyers ended up being top heavy. It was one of the contributing factors to the capsizing of ships Halsey lost in the typhoons he steamed into.
Of course, the Burke requirements could have changed too.
Come on this is Free Republic. No one is yet blaming the union workers in the shipyard? The problem can’t be from design and engineering. It must be the workers who are at fault, just like the Big Dig.
I don´t think it is a stealth, This has been a problem with US destroyers since at least the 1950´s.
I was on a British cruiser in 1953 doing high speed exercises with the US Navy in the Shimonoseki Straits, the US destroyers were dropping out one by one with their bows buckling and plates parting.
They say welding is as strong as riveting, which it is, but needs more skill and in those days it was much more difficult to identify the flaws.
Halsy ordered the ballast pumped out of the empty fuel oil tanks in preparation for taking on fuel. Those ships sank because of Halsey’s poor judgement, not because of steel in the tin cans.
Halsey should have been court martialed for the loss of life and ships he caused.
The problem is the crew is running up the revs and throwing it into reverse pitch on the prop. They play these games when they are bored.
The release of the info makes sense if you want to have an argument available for budget purposes, political purposes, or even laying the argumentative foundation for new ships a decade down the road. Better to expose it now. Cleverly Machiavellian.
Are they made of tin foil?
I hope airplanes aren’t made so cheap.
Didn’t Bath Iron Works in Bath Me. build most of these ships?
Failings of this kind are unavoidable. It’s what happens every time something new is designed and built. It would happen even if everyone involved was totally competent and money wasn’t an issue...which, of course, is NEVER the case.
I'm not sure Halsey ordered it, but yes, the seawater was pumped out in expectation of refueling, but the weather was too bad, and becoming worse, to actually refuel. It was attempted, but not achieved. Over two days, iirc.
The ships were still top-heavy, fully fueled, with the added armaments, armor, and other equipment.
Yeah, Halsey remained in command too long, as the war progressed. One typhoon, maybe. Two? Fire him.
