Formed in the demobilization following WWII the newly formed USAF grabbed as much power as it could in a drastically reduced force size.
It was also a time that the newly developed helicopter was viewed as useful only for observation and light medical evac. Kind of similar to beginnings of fixed wing aircraft. A role that the AF was willing to concede to its mother service not envisioning the advances in size, performance, and armaments possible.
The bomber and fighter crowd saw the rotor craft as a sort of flying jeep, too lowly for them.
Technology started significantly changing the game only during the Viet Nam war IIRC.
It’s long past time to re-evaluate and re-assign assests. And because of entrenched power structures within the military that will not voluntariy surrender their ricebowels the change has to come from civilian authority.

Joint service has been a reality for some decades now and has proven its worth in multifold ways. See this article for just such an example:
