How can a jet protect ground assets in the age of hypersonic weapons systems and drones? Anyways, isn't that the job of ground air defense?
"Hypersonic" weapons used in current conflicts are nothing more than a glorified long range missiles that are useless if you can't launch them from the air. They're also currently statistically not significant due to their low amounts.
EDIT: replaced “boomers” with “bombers.” Not sure my grandmother is going to be blowing up much materiel…
