Dont know anything about missiles, but jets wont work. At least not the Eurofighter for some reason.
Apparently an NSA contractor has to type in a key before every start.
>Damit die 15 Eurofighter auch wirklich starten dürfen, zahlte Österreichs Bundesheer in drei Jahren 1,5 Millionen Euro an eine private US-Sicherheitsfirma: Jetzt wurden die Kosten für jene am Fliegerhorst Zeltweg stationierten zwei "Zivilisten" bestätigt, die jedes Aufsteigen eines Jets mit einem aktuellen US-"Crypto-Schlüssel" für die Navigation und die Freund-Feind-Erkennung zulassen müssen.
>In order for the 15 Eurofighters to start, Austria's federal army paid 1.5 million euros over three years to a private US security company. Now, the costs for those two "civilians" stationed at the Zeltweg air base have been confirmed, who have to allow every start with current US-"Crypto-Keys" for navigation and friend or foe identification.
The ministry of defense denies that the two Americans from a not named US company are NSA contractors. They claim the jets would fly without but without encrypted navigation and communication. He also mentions the same situation for Sweden and Switzerland.
