XF-114 is equipped high thrust engine able to flew high speed and high attitude, and has 1 long range missile to destroy enemy bomber at long range, and has high-G maneuver for dogfight with escorters. F-114 is named "Skywarrior", served more then 20 years with several upgrades. however, soviet successfully developed ICBM, America realized now they are shooting rockets to deliver nukes, not to airplane. so F-114 is no more used for intercept bombers, they now used in vietnam and use with Phantom.
