"The F-14 is equipped with an internal 20 mm M61 Vulcan Gatling cannon mounted on the left side (unlike the Phantom, which was not equipped with an internal gun in the US Navy), and can carry AIM-54 Phoenix, AIM-7 Sparrow, and AIM-9 Sidewinder anti-aircraft missiles. The twin engines are housed in widely spaced nacelles. The flat area of the fuselage between the nacelles is used to contain fuel and avionics systems, such as the wing-sweep mechanism and flight controls, as well as weaponry since the wings are not used for carrying ordnance. By itself, the fuselage provides approximately 40 to 60 percent of the F-14's aerodynamic lifting surface depending on the wing sweep position, mainly due to the lifting body characteristics of the fuselage."
