The Navy ’s newest warship is slow disappearing , one atom at a time .
This is n’t a sequel to the 1984 sci - fi flickThe Philadelphia Experiment , in which a Navy destroyer - escort vanishes through a sentence portal in Pennsylvania only to reappear in Nevada , 40 years later .
No , this clock time the radioactive decay is real . And so is the leave tension between the Navy and the vanish warship ’s upstart builder .
The afflicted vessel is USS Independence , the second in the sailing limb ’s fleet of truehearted , reconfigurable Littoral Combat Ships . Eventually , these ships are supposed to be the “ workhorses ” of tomorrow ’s Navy .
AsBloomberg reported , the Navy has discovered “ aggressive ” corrosion around Independence ’s engine . The problem is so bad that the barely class - old ship will have to be lay up in a San Diego drydock so doer can supercede whole chunks of her Isaac Hull .
In demarcation to the first LCS , the steel - hulled USS Freedom , Independence is made mostly of Al . And that ’s one root of the ship ’s ailment .
corroding is a$23 - billion - a - yr problemin the equipment - heavy U.S. armed services . But Independence ’s decay is n’t a lawsuit of mere oxidation , which can commonly be prevented by careful maintenance and cleanup . No , the 418 - metrical unit - long war vessel is basically dissolving , due to one whacker of a design defect .
There are technical terminal figure for this kind of annihilation . Austal USA , Independence ’s Alabama - based builder , calls it “ galvanic erosion . ” Civilian scientists recognise it as “ electrolysis . ”It ’s what happen when “ two dissimilar metals , after being in electrical physical contact with one another , corrode at different rates , ” Austalexplained in a statement .
“ That suggests to me the metal is completely gone , not rust , ” naval analystRaymond Pritchett write ofIndependence ’s job .
Independence ’s corroding is concentrate in her water jets – essentially , shipboard reading of aeroplane engines – where blade “ impeller housings ” follow in contact with the environ atomic number 13 structure . electric charges perchance originating in the ship ’s combat arrangement apparently trigger the electrolysis .
It ’s not clear why Austal and the Navy did n’t see this coming . Austal has work up hundreds of aluminum ferryboat for civilian customers . The Navy , for its part , has operated mixed aluminium - and - brand warships in the past .
But independency – the Navy ’s firsttriple - hull scrapper – could be a special pillow slip for both the builder and the operator . For all Austal ’s chops building civilian ferries , the Australian company is raw to the warship business . Austal arrange up store near Mobile in 1999 . Today , the shipyard has declaration to build 10 LCS plus several catamaran transports for the Navy .
From the Navy ’s breaker point of perspective , Independence and the other Littoral Combat Ships are unequaled . As in , unambiguously cheap . Each vessel is supposed to cost just $ 400 million , compare to more than a billion bucks for a large , all - steel Arleigh Burke - class ruiner .
fortune of thing – major weapons , for one – have been result off the LCS in ordering to keep the price down . The list of delete detail includes something call a “ Cathodic Protection System , ” which is plan to prevent electrolysis .
independency will get the aegis organisation installed at the first chance , and future LCS will include it from the get-go , according to Pritchett .
But instead of simply charge the corroding yield under “ example learned , ” Austal seems compulsive toblame its client . “ Galvanic corrosion has not been a factor on any Austal - progress and fully - maintain vessel , ” Austal accent , implying that Independence has n’t been “ fully maintained ” by a negligent Navy .
That ’s an , ahem , interesting approach to client relations for America ’s newest combat ship - builder .
And things could get worse , as more LCS infix the fleet . “ I mistrust there will be other public problem revealed over prison term that will require relatively dim-witted , albeit dear , solutions , ” Pritchett write . Will Austal also blame the Navy the next time a glitch appear in the ships it builds ?
