A meteor missile costs 2m $. Even if we buy 300 it makes 0.6 bn. We dont need any other munition. For that money we should have obtained the right to integrate our own munition. Even if we buy a whole plain in spare parts 40 * 120m € makes about 5bn €. So we have been screwed big time! As Öztürk Serengil said „Bu kazik degil Roma mizragi“

But it was necessary to buy, yes.
We wanted to buy something like a 1000 a2a missiles from US with Viper and about a 1000 bombs, we asked for guidance kits, training bombs etc andwe are not going to buy any less for the Eurofighters. In fact, since we don't already have an exist stock for them, I'm willing to bet we asked for even more than that.
When we were trying to get F-16s, we didn't just ask for 40 planes and called it done. We asked for something like 10 spare engines for those planes. We didn't just ask for 40 AESA radars, we asked for 10 or more spares. We did it with every single critical system on the plane. From displays to targeting pods to EW systems to mission modules and every single system you can think of, we asked spares of GPS systems.
We are not buying a bloody car and driving it home, stop thinking it like that.
Which infrastructure? Hangars? Or some gadgets to repair and upkeep the planes? Or oil filter etc?? Fed up with this logistics bs. Lets agree they caught us in a weak moment and exploited it. And then move on.
Okay, this just shows you need more education before continuing this conversation mate. We are paying about the same with other countries that purchased the plane. If you want to go against the facts and believe we were fucked, go ahead. Nobody can make you see the reality while you reject it so completely.
Edit: In fact, here is everything we asked from US for 20 billion. Forget the planes and upgrade kits, just take a hard look at the spares, other systems and munitions we asked for. And this is for a system that we have been using for decades, that we already have spares and whatnot for. We are building this ecosystem for the Eurofighter for the first time.
