One of the first lessons learned from the Vietnam War was despite the invention of air to air missiles, planes still needed guns. Because of this, the F-14 was equipped with the M61A Vulcan cannon which was a gatling gun. It was also equipped with the AIM-54 Phoenix Missiles and a pretty impressive fire control radar which could engage 6 targets at one time. It was primarily used in the role of Fleet Defense but could tear it up if it had to.
The F-14 also took some cues from the F-111 in that it was a swing wing fighter. This allowed it to optimize its flight profile depending on what kind of flying it was doing. Basically, it can behave as a delta wing aircraft in supersonic flight and a straight winged aircraft in normal flight. It could go a little over Mach 2 if it had to.
This particular version is the D model of the F-14 which gave it a larger engine and more maneuverability. In the early 1990's, the Tomcat was given the ability to attack ground targets and did a pretty good job of it. Sadly, it was retired in 2006.
