In one more Argentine military aviation exercises index, we disclose an updated version of our original Aeromilitaria Argentina index for year 2004. This more complete alternative reviews nearly 50 exercises, simulations and drills totalling at least 240 days of activity on the field. Another “international” year, 2004 was packed full of combined exercises, including exceptional events such as two different UNITAS phases, a Gringo Gaucho carrier qualification tour onboard USS Ronald Reagan and a (now) rare Argentine-British maritime search and rescue cooperation exercise.
