During the Korean War, the U.S. Military flew more attack missions than
any other type of mission. The U.S. Navy and Marine Corps flew most
of their attack missions with piston-engined aircraft.
In 1957 the Navy selected the Grumman G-128 in a competition for a
long-range, low-level tactical strike aircraft. The first flight of
the prototype was made in 1960 with the type entering service in 1963.
The Intruder saw extensive service in the South East Asia. When
the last A-6 variant left the production line in 1990 more than 660 had
been built.
