To most knowledgeable and intelligent people, one of the finest jets of the Cold War is the F-4 Phantom II. Those lacking proper perception willundoubtedly differ in this matter, however, it isn't too late to come to yoursenses! :o)

Other than perhaps the Mig-17 or Mig-21, no other post-Koreanwar jet has been built in greater numbers. Certainly no other non-Sovietdesigned aircraft. There must have been a reason for it. It certainly isn'tsimplicity or ease of maintenance. The Phantom was one of the last Westernfighters where the airframe was designed first and then room was found for otherequipment. Nowadays, ease of maintenance is as important as any other factor. Itcertainly wasn't designed to be stealthy. Nothing like two smoke trailsfollowing several tons of hurtling metal to make yourself visible! It alsowasn't designed to be quiet. If you have ever been around the beast withoutproper hearing protection, your ears will definitely be ringing.

What made it such a success is that it was able to perform avariety of missions and perform them all well. Probably your first decentmulti-mission aircraft. It was an interceptor, a (unwilling) dogfighter, asuperb ground attack aircraft, a night fighter, a level bomber, a SAMsuppression aircraft, and a blast to fly. Before that, aircraft were generallyspecialized. After the Phantom, there were still purposefully built aircraft,but it lead the way to today's multi-mission aircraft.

Though mostly gone from the inventories of the world's air forces, The F-4 is still being flown by the Greeks, Turks and the Japanese amongst the few. The Japanese planes, aside from the first two EJs and the RF-4EJs, were all built under license by Mitsubishi. Though the numbers have dwindled down over the years, the F-4EJ kai is still being flown as are some that have been converted with recce pods.
