That is actually a very meaningful order. I had to check, did they mean launchers or batteries. Looks like 17 batteries. That's pretty big, IRIS-T is very modern kit.
It's 17 Batteries, each having 3 launchers capable of shooting 8 missiles each, that's a total capability of launching 408 missiles at once. I already explained this 2 you in another post, where you had the audacity to call me daft?!
