Back in the 80s it was suspected that the NSA was about 10 - 50 years ahead of the other code-breaking organizations in the world.
It may have been true, but that gap has deteriorated, and with the advent of modern desk-top computers, it's not known if they have any kind of
significant lead in that field. I'm basing this mainly on comments made by Bamford and other
followers of these black agencies.
As far as the arms forces having craft or technology 50 to 100 years in advance of current manufacturing, I'm calling BS. It's one thing to be that
advanced because of having a monopoly of the resources (as NSA did in the 80s), and be advanced in math, but these people would have us believing that
we that advanced amount of equipment (and the necessary exa-flop computing power). It's nonsense.
As far as stealth, it's suggested that a 10 year gap is a reasonable assessment for our lead over the other industrialized nations.
As I mentioned in another post, the projects which are greenlighted are also put under financial constrants and they're done to fulfill a project
request. IOW, the AF orders a low observable craft, and Lockheed, Boeing or Northrop submit bids for it and make prototypes and then there's a winner
and a production run is made.
Other craft would be done with a similar model. They don't normally do one-offs, with a possible exception being something lie a test-bed project as
was the Sea Shadow for the Navy. They don't do projects for requirements which don't yet exist, (such as would something 100 years in the future.
What's important are the production methods, how materials are acquired, how much can be put together with off-the-shelf equipment, how costly it
There's absolutely no evidence for either this level of production methods in existence and no off-the-shelf anti-grav engine to build upon. There's
certainly no need for these either. We have almost total control of the skies, and except for the need for a more robust anti-anti-satellite weaponry
we're building the Joint Strike Fighter.
With absolutely no evidence of these methods, some 'background leakage' of these supposedly exotic craft, and production methods, I'm seriously
doubting this is happening.
Now, had we already built a robust space delivery system, a strong permanent ISS, and a thriving base on the Moon, THEN I might be convinced there
could be a hidden exotic craft industry.
