There has been one US F35 damaged in combat. That's total, across all the areas its been in and all the countries that have deployed them, starting in 2018. They've been up against the best air defense systems in the world in Venezuela and Iran and they received a single scratch.

The countries acquiring them are doing so because they are best strike fighters on the planet, and it's not even close. Unless you know something that Norway, Japan, England, the Netherlands, etc don't know?

Holy non-sequitur batman.

Why would Japan mass produce an inferior product when they would easily be able to design and build a far superior one? "Shahed" isn't just another word for drone, it's a specific company's name.
