The USAF is already over-equipped to handle any imaginable air superiority problem. Today, Air Combat Command is capable of handling any coalition of air superiority threats. In Germany during World War II, US numbers, not quality, reigned supreme. The USAF has always had and has always depended upon superior numbers to win. Numbers guarantee victory.
Numbers develop intensity and allow multiple attacks.
The US has no realistic future air superiority problem facing it. A sane US will not war with India, China, or Russia. Nor will we war with France, England, Japan, and Germany. Other countries are not threats. Nor will we war with our friends to whom we sold US aircraft.
