of stealth to the platform using it. Further negotiations between Hanwha Thales
and the military will now take place and a contracted is expected to be awarded in June
for AESA radar’s, the report said. “The technological capacities and cost efficiency
were the two main categories in selecting the priority negotiation partner, along with

  2. I suggest Lockheed-Martin will involved with the design. This would allow South Korea to build a near F-22 to customers who want them, whereas the F-22 cannot be sold abroad. This could be a partnership which will grow in importance in the future.

  3. If Korea makes a fighter plane, it will not have to be made about 200 machines. Unlike other countries, fighter aircraft maintenance method is special. In Korea, fighter aircraft maintenance method in Korea is called cannibal improvement which procures parts from moving fighter aircraft. Probably the expectation that you can move normally after 10 years will be around 10%.

  4. This is a very wonderful type of stealth combat aircraft. I hope that in the future, my beloved country could some how request a belateral talks for a possible procurement of this type of aerial arsenal from South Korea.
