I think lots of people were wrong about the F-35. It is a very good warplane even though it cost a ton of money to develop. (Military aviation nerds, feel free to contradict me)
I look at Finland as a country that takes defense seriously and expects to fight hard with exceptionally degraded facilities and logistical support. They chose the F-35 vs. the Super Hornet+Growler, Gripen+GlobalEye & Rafale means something. At a minimum they think the marginal cost of the aircraft is worth the supply chain it offers.
I strongly suspect that the aircraft is a far more capable electronic warfare platform than is generally understood. A very good local defense blog covered the process extensively and is well worth spending time with - https://corporalfrisk.com/2021/12/11/f-35a-is-hx-the-winner-...
Also a great budget to bury black projects...
