Last month, it looked like South Korea was going to buy 60 F15's. Now we are not so sure. The Koreans have announced they have re opened the competition, with the F35 and the European Typhoon back in the running. The Korean Defense Minister said, "There is a consensus that South Korea needs the 5th generation fighter jet to deter the growing threat posed by North Korean". Aviation Week says this means the F35 will win.
This is a tremendous disappointment for Boeing, they were hoping for a big order to keep the F15 production line running. But it's understandable, the F15 is old, and the South Korean Air Force really wanted to be flying something up to date. Fifteen former Korean air force chiefs wrote an open letter to the Korean president supporting the F35. On the other hand, it's a great boost for Lockheed Martin, who needs the sales.
F35 isn't getting any cheaper. Last month Aviation Week quoted the cost as $97 million. This week they report that negotiations the Low Rate Inital Production batch 7 will be $96.8 million, LESS engines. That's a biggy, engines are usually 25% of the cost of an aircraft, so with engines, the F35 is hiked up to $125 million. Each. Ouch.
Plus, F35 is a totally software product. The software to launch missiles, aim guns, jam enemy radar and drop bombs is still under development. Only the basic "aviate and navigate" software is actually running in the aircraft. Until that software is finished, the F35 is not a warplane, it's just an expensive trainer.
