This is another design from the era of bad ideas. The concept was that of a "Super Tomcat", if you will --- by grealy enlarging the basic F-14 design, I figured it would be possible to fit a more powerful FCS, carry larger payloads on more numerous weapon stations, equip more powerful engines, carry more internal fuel, and use larger missiles with an exponentially longer range. In short, it's the "Homermobile" of combat aviation.
I'm actually planning on re-designing the F-133 into a more practical warplane, but that will take some time.
