&gt; the F-22 was also over budget and under-delivered on expectations. So much that the Pentagon canceled the remaining production run after 195 aircraft<p>It was canceled because it was expensive and no longer needed, because the mission it was designed for - fighting a peer enemy - no longer existed. That was 2009, when the U.S.&#x27;s primary military concern was fighting two simultaneous wars against enemies who didn&#x27;t own one airplane or air defense system. Any plane could do the job; we didn&#x27;t need F-22s. Also, our prior generation planes were still the best in the world.<p>Seven years later, Russia and China have engaged in massive military military buildups, including significantly improving their air combat capabilties, and aggressive behavior. The peer enemy mission is back at the top of the list (and some are now talking about re-starting F-22 production).
