They have a ship industry, they have an *aerospace* industry, they have a technology industry....
They’ve had the aerospace industry since the 70s, though there was consolidation and the sole survivor was a joint venture that went independent of Samsung, Daewoo and Hyundai (who started it.) https://en.wikipedia.org/wiki/Korea_Aerospace_Industries
Yes,I certainly knew that the ROK had a tech industry.My hard drives and SD cards were all made there...as is one of my TVs. However,aerospace surprises me 1) because Korea is a fairly small country and 2) because of the competition with US and European companies.
