How did airplanes make World War 1 different than the other wars?
The armament in WW1 was limited to 1 or 2 machine guns that fired at 150 to 250 rounds per minute. During the peak of WW2, the figthers were armed with 6 to 8 machine guns that were larger caliber and fired much faster. Some had additional armaments of cannon—even though some WW1 aircraft used cannon, too.
