Sophisticated fighter aircraft are expensive to develop, manufacture, and operate. 
To lower these costs, focus has shifted to multi-role planes that can be used by all branches of the armed forces. 
The US Navy's F-14 was one of the last specialized fighters, a heavy and complex aircraft with powerful engines,
sophisticated avionics and variable-sweep wings.
A high sweep angle is beneficial for transonic and supersonic speeds but slower speeds require the greater lift and stability of straighter wings. 
An onboard computer adjusted the F-14's wings automatically to optimize wing sweep for a given airspeed.

The museums F-14D was the last F-14 to launch from an aircraft carrier on an operational deployment over Iraq.
Its final flight was into Charlotte/Douglas and was decommissioned at the NC Air National Guard.
