They could only buy 28 of them for their 7.7 billion.
It's a great plane though.
The Nork’s SOLE advantage, and primary threat, is that they can kill a whole lot of people in a very short period of time, with 10,000+ artillery tubes pointed at Seoul.
They don’t need to be high-tech to lob a 20-lb. shell.
Yes, we can take them all out eventually, but how many die in the meantime?
The main problem with costly fighters is their number.
Equipped with 6 air to air missiles you may shot down 6 enemy fighters but what happens then your enemy can effort 7 times more cheap aircraft?
On of F-35s mayor problems is the price and after that comes “can’t turn can’t climb can’t run” (RAND corporation). Without missiles left the seventh MIG21 will be a big problem.
