KAI showed off its latest UCAV concept at the Seoul air show last month.

It looks pretty much like just about every stealthy UAV out there, mostly because the way that air flows, and the way that radar bounces off of objects, works the same regardless of country of origin.

One of the dirty secrets of stealth is that not only are the basic principles public, but they have been since the beginning, having first been publicized in a Soviet unclassified scientific journal.

I think that we will see a lot of these systems, particularly in an anti-ship capacity, where deterring US aircraft carriers has a lot of value on the international arms market.
