All this knowledge of chemistry, metallurgy, etc, etc, and all this is supposed to come
together in the most advanced airplane yet they can't make parts that don't rot sitting the parking lot? WTF?? |

I was told I was an idiot who didn't understand. Whoever wrote this article must similarily be an idiot questioning why a 100 Million fighter isn't parked in a 200K hanger. |

Why can't we just coat them all in tenifer
 ?

The Navy has been flying aircraft in a corrosive environment for decades and doesn't seem to have this problem. WTF?

Are the coatings themselves corroding the aluminum or is it some kind of galvanic reaction with a dis-similar metal?

Probably just an excuse or a cover up to spend more money updating it i seriously doubt they spend millions on a jet and use cheap material.

You don't understand, but I don't recall you being called an idiot. However, weather is not a factor in this case. It's the radar absorbant materials themselves causing corrosion. Wouldn't matter if it was inside a hangar or not. |

It's real obvious that you have never worked on a Naval aircraft, especially ones made by Grumman. The F-14, A-6 and EA-6B were / are corroding piles of shit. Who uses fucking spot welds to hold their panels together on an aircraft that's going to be operated in a corrosive environment.

Supposedly corrected in the F-35. Lesson learned from the F-22 that was applied to the F-35. |

Yep, the one I clicked on didn't mention the actual cause but if it was the actual coatings I guessed pretty damn good. Aluminum "rusts" by creating aluminum oxide on the surface and is pretty self limiting to a certain extant unless there are some issues with the alloy itself or with galvanic reaction. And Lockheed should be responsible for the repair costs if due to poor testing of the coatings or a product defect. |

I wonder if the air force has ever regretted not choosing the F-23.

Time to stop giving Lockheed contracts.

Quoted: Time to stop giving Lockheed contracts. Why? We're having fairly serious corrosion issues with our 5 year old C-17s here. They were built by McDonnell Douglas/Boeing. We have a lot of composite in the structure, and the places we are seeing issues are mostly at the composite/aluminum joins. All metal airplanes are easy, we've been flying them for 80 years and the problems are well understood, but composites are still a young field by comparison. With all of the unique coatings and materials used on the F-22 it's no surprise they don't all perform as expected right out of the gate. |

Quoted: We use the same materials as commercial aircraft, so I'm not surprised. Wait until the 7late7 enters service, that's going to be interesting.
