With the advent of the GE F110 turbofans now upgrading the Tomcat to the A+ and D model designation, it moves the Tomcat into thrust to weight ratio of the PW100 powered F-15. I do believe however, that the USAF has been purchasing F110's as substitute systems for the Eagles. The F-15e model comes to mind. Though I do not know if the F-14 practices that manuever. Al
