We have never had any real threat to our overwhelming air superiority since Vietnam… and really not even then. However that particular air war still remains instructive, even if may not be very relevant in today’s world. More recent air war successes in the Falklands, Bekaa Valley, Desert Storm or Kosovo provide too small a sampling to make sweeping judgments about our air warfare capabilities, especially if we are ever pitted against a truly formidable opponent. These were relative skirmishes, thus Vietnam remains the better air war to analyze because of its broader scope. And while the AIM-4 and AIM-7’s performances were abominable, the Sidewinder and the ship launched BVR Standard missiles were superbly successful.
People tend to forget that the US lost 10,000 aircraft in Vietnam! Nothing compares since then. While the majority of losses were helicopters, we still lost 1,000 then state-of-the-art fighter and attack aircraft. Remember this was against a 3rd World country with a very small and unsophisticated air force against a "super power."
What makes Vietnam still relevant has little to do with comparing technology or missile systems, then or now. It is this: We entered that air war with overwhelming and far superior assets in every category, better technology, and in far greater aircraft numbers. We also entered it with overconfidence, if not some hubris. Yet this third world rag-tag small air force and their air defense systems knocked down a thousand of our front line aircraft and captured several hundred of our pilots. Indeed 89 of our aircraft we shot down by vintage MiGs with old guns and deplorable missiles. Yes there are many other reasons for these losses, but overconfidence in our capabilities was significant among them.
If we are ever unfortunate to find ourselves in a real large scale air war of epic proportions and well beyond that of Vietnam, with a country that also has large and capable air warfare forces like ours, let us hope we do not let overconfidence in our capabilities handicap us.
