The last big wow moment in defence tech was stealth and the first US stealth plane flew in 1977. The next country to develop stealth was the Russians in 2010! Now consider its 43 years later with computing technology power that was beyond the dreams of the engineers working on stealth in 1975-1977 and with US military budgets that have been at times larger than the rest of the world's spending put together. I'd expect that the current state of the art experimental US military tech would be considered by many to be "out of this world".
