A- (plane)
The
prefix A-, in US
military aviation, refers to a type of plane generally considered an
attack plane. Currently, the most famous attack plane is the
A-10 Thunderbolt II.
Since
World War II, there have been two major, broad types of aircraft:
fighter aircraft and
bomber aircraft. However, between them were classes commonly known as
fighter-bombers, including
heavy fighters (notably the
P-38 Lightning) and attack aircraft.
There were two distinct time periods in which attack aircraft were designated by the
A- prefix:
1926-
1947 (mainly Army/Air Force) and
1962-present (the unified system). The first ranged from the
A-3 Falcon (only counting those that made it past the experimental stage) to the
A-36 Apache. These ranged from
biplanes to bomber-like
monoplanes.
However, during that time period (during which
World War II was fought), the
pursuit fighters (with the prefix
P-) were more popular types of fighter-bombers. Instead, the most famous attack planes came after 1962 (especially during the
Vietnam War). The A-10 is the archetypal attack plane: it was able to manage fast speeds (450 mph or so during combat), while able to slow down to under 200 mph to provide an advantage in air-to-ground combat. It and other attack planes is meant to provide close ground support (i.e. rockets and machine guns vs. tanks and infantry), and cannot perform well in a normal air-to-air or air-to-facility (runway, building, etc.) role.
