Austrian jets intercept US military aircraft in back-to-back airspace violations

Austria declared permanent neutrality in 1955 as part of the State Treaty that restored its sovereignty after World War II. That status prohibits membership in military alliances and requires enforcement of its airspace against unauthorized foreign military transit regardless of the originating country. Austria is a European Union member and participates in some partnership frameworks with NATO, but it is not a NATO member. Unauthorized military airspace entries by partner-nation aircraft are uncommon and are typically resolved through diplomatic and operational coordination before an intercept becomes necessary.
