Costly corrosion problems on the F-22 caused by stealth materials and coatings have been addressed on the F-35, but risks remain, concludes a report by the U.S. Government Accountability Office. The GAO's presentation to Congress on its review of the DoD's corrosion evaluation report on the F-22 and F-35, completed at the end of September, says:
"Corrosion of the aluminum skin panels on the F-22 was first observed in spring 2005, less than 6 months after the Air Force first introduced the aircraft to a severe environment. By October 2007, a total of 534 instances of corrosion were documented, and corrosion in the substructure was becoming prevalent. For corrosion damage identified to date, the government is paying $228 million to make F-22 corrosion-related repairs and retrofits through 2016."

They need to add a few more zincs
If its the paint used on the F-35 making the difference... can they use that on the F-22??
Or would government never think of that?
Why would they care, somebody else paid for the planes.
Says it all... How long until our military needs a permit before firing a missle due to environmental and occupational health concerns...
this was corrected on later built rapters and is being addressed on the earlier built ones, and yes lessons learned made sure that the JSF didn’t have this prob, but then again, the b model requires special deck plates for our carriers, to prevent deck plate warping, and the v-22 opsprey has a sililar problem. When you move the ball this far stuff gets lost in the shuffle. Bigger problem is the stealth coating needs alot more repair then anticipated, hopefully the robots that take care of the b-2 will drive down that cost and time.

“”Environmental and occupational health concerns drove the initial use of a nonchromated primer on the F-22 that did not provide corrosion protection

I am sure the Russians and Chinese are just as environmentally and litigation minded as we have to be...NOT!
