well,yes,that's your secret technology...but I was talking on a much bigger scale,like the army,where you need hundreds of researchers...
But in most cases 99% of the "tech" required for a particular project will be in the public domain; it is only the last 1% that is "top secret", even if you are e.g. building a top secret electronic device you will still be using ordinary resistors, capacitors etc; only a small part (lets say the algorithm that is used in the DSP) is actually secret.
Hence, the university education will be useful for 99% of the project and will also give you enough background information to be able to learn the last 1%
Also, I don't believe there are any top secret "single" projects that involve hundreds or researchers even in the army; if nothing else simply because it is not a very productive way or working (and if would be impossible to keep secret, SOMETHING would leak from an organization that big).
Projects that require the contribution of that many people (lets say building a new bomb) will be broken down into smaller problems and each small problem will be handled by a relatively small group of people; and those people will only know the details about the things THEY are working on. And most of those small projects won't even be that secret on their own.
Also, on a more practical note, most of the "top secret" research being done in the army is more engineering than basic science. Hence, they are not really developing new technologies from scratch, it is more about using existing knowledge in a new way (from that point of view they are no different from a company).
It is true that the US military (DARPA,IARPA etc) funds a lot of basic research, but most of those contracts are awarded to civilian organizations such as universites etc and it not really secret (the US Army even awards contacts to foreign universities).
The basic idea is to encourage research in a particular field and it is not until the the field is relatively mature that they will then use the knowledge in their own "secret" labs to build top secret gizmos.
