I am surprised so many people support the game running to 3000AD *shudder*. I hope Firaxis stays true to the tradition of having the game end somewhere between 2000AD and 2100AD to allow for near future techs, but no more. My most preferred end point would actually be between 2010-2050, since we can at least make educated guesses at what technologies will be available at the end of the period and we more or less know almost exactly what technologies will be around by the beginning of the period, because they are in the process of being designed at this very moment. Beyond 2050, I think it becomes extremely difficult to make any guesses at all. For example: Will we have discovered faster than light travel by 2200? Is faster than light travel even possible on a macroscale? It is not really possible to know at this time, but we can say with reasonably confidence that we will not have spaceships travelling faster than light by 2050.
As to the history of American stealth technology... the first aircraft that was designed with reduced radar profile in mind was the U-2, but it cannot be called a stealth airplane. The technology gradually matured and more advanced 'pre-stealth' technology was deployed on the SR-71 spy plane. Next came the B-1 bomber that used more advanced low observable technology yet and it is considered to be a semi-stealth aircraft. Quickly thereafter came the F-117, which was the first true stealth airplane - the first 'stealth fighter' flew in 1982. True, by now the stealth used on the F-117 is not the best that is available, but at the time it was top notch. B-2 came next and represents a huge jump over the F-117. It is much more stealthy, has a large payload, a long range, etc.
The newest stealth aircraft - the F-22 (currently in low rate production - some are already available) and the F-35 (in development) represent another jump in capabilities. The F-22 is approximately equally stealthy to the B-2, but it does not sacrifice maneuverability, speed, payload, range, etc. to its stealth capability and is at least equal to the best conventional aircraft in these respects, in most cases it is much better (for example it has the supercruise capability (no other aircraft in production has this capability), which means it can maintain supersonic speed without the need to fire afterburners, which burn a lot of fuel and therefore greatly decrease range) + it also has excellent stealth as an additional capability. The F-35 is somewhat less stealthy than the F-22 and lacks some of its other capabilities, but it is much cheaper.
