No, it's not "baloney".

There are multiple layers, some baked in and some sprayed on as part of the paint process (obviously necessary).

Respectfully disagree. Was widely touted that unlike the -22 , its stealth was baked into the skin and not reliant and maintenance heavy coatings. Now we learn if the coating wears off, is damaged, the AC is visible on radar. So what was all that talk about not being able to tell how stealthy something was by looking at its shape? The 35 isn't a stealth shape and electromagnetic physics hasn't changed. It has been fairly obvious to many that the 35 was not a LO AC and they slapped on RAM to cover up the lack of shaping.

Low RCS can be achieved. tho Infra red, not so much.

The challenge however is to make the lo-lo-lo trajectory possible. Thus allow horizon masking.

Which is all bizarre because from the onset it was said that the stealth was baked into the skin, and would not need LO "coatings",  and the "skin" would get more stealthy from wear.

So the early PR was entirely baloney?

The X-27 stuff would be of interest to me as well.  Combined deal?

I'm in, however there's other stuff I'm interested in at the Huntingdon Library. E.g.
Kelly Johnson's papers:
http://pdf.oac.cdlib.org/pdf/huntington/mss/johnsonc.pdf

e.g. Box 9
Folder 8 Subject Files - CL-1200 Lancer/X-27] "CLJ's trip to Washington, DC on August 17-19,
Correspondence and Memoranda (1971-1974)
Folder 9 Subject Files - CL-1200 Lancer/X-27] "CLJ's trip to Washington, DC on August 17-19,
Schedule (1971, Aug. 17-19)

Northrop Corporate archives:

Anyone live near San Marino, CA? Might be worth a visit with a digital camera :)

The Rafale D on the drawing reminds me of this (see in attachment, first file was an article in an old French magazine (Air).

FYI: With people here and on the APR Patreon, the list is currently about 23. So even if it comes in at the full $400, we're down to $400/24 = $16.67 per person. Which ain't too shabby.

I have high hopes of hearing back from the Library next week sometime with details about contents and cost. Might as well tack on the Box 2 Folder 9 "CL-1981 Low Cost Fighter" stuff as well...

PS: those who are interested, please PM me with your email address.

The source is the daily mail, which is a total rag. Second source?

Who is their source?

But maybe you can too ask Vice Adm. Mat Winter, the head of the government’s F-35 Joint Program Office or LM Jeff Babione.

Did they actually say anything about coating wear rates?

“It’s not a human problem; that’s just the result of our ability. We’re approaching the limits of our ability to build some of these things from precise-enough technology,” a Lockheed Martin spokesman told reporters overnight, admitting the company was having issues with the Low Observable coating.

Which says nothing about coating wear rates. In the defnews article, he was talking about panel alignment there and
goes on the talk about factory rework; respray and overspray.

Yep. "Precision" pretty much has nothing to do with painting.
