At Rense.com, a writer claims:
The United States is known to have a huge budget for so called ``black projects,'' because it spends more on defense than can be accounted for by adding up the value of public programs.
Are there any good examples from history of it being revealed that the US government knew about some technology long before the general scientific community did?
The two most obvious examples I can think of are
- The Manhattan Project: However, I'm not sure how private it actually was -- I know they were very secretive about details (which are of course very important!), but the basic science was already widely known, I think.
- RSA: I remember that a British mathematician later revealed to have discovered it before R, S, and A did, but it was kept quiet because of a security issue. So that's a good example, I think.
