 The F-14's fuselage and wings allow it to climb faster than the F-4, while the twin-tail arrangement offers better stability.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.
