Geez.  How close to us are the Chinese?  Known but classified capability gaps?  Enhancements for the F-15EX and F-15E?

Just how bad is the F-35, how many more F-22s do we need and what has the USAF so spooked that they need to plan enhancements to an airframe that that was supposed to be just a missile truck?
