As a result, the "Luftwaffe" set up two tactical training centres: one, like those of many of the NATO forces, at the Royal Canadian Air Force base at Goose Bay; and the second in a unique partnership with the United States Air Force at Holloman Air Force Base in New Mexico (F-104 pilots had already been trained at Luke Air Force Base, Arizona, since 1964). Both facilities provide access to large unpopulated areas, where tactical and combat training can take place without danger to large populations.
