Respectfully I find this to be a bad comparison. A CAS aircraft of the 2030s does not need to perform the mission as something from the 1920s-1940s lol. The future of CAS can be broken up into a lot of possible scenarios . You do not need a subsonic ground attack aircraft flying around vulnerable to SAMs, small arms, enemy aircraft, or anything you can dream of. A near future call for CAS (~5 years time) could see a ground element using someone like ATAK linked to JADC2 to call in GBU-53/Bs from nearby F-35s. The F-35 never seen the target, they just had to authorize the munition launch. The ground element could order nearby OWA drones or launch ALEs from nearby rotary wing aviation. All without the host platform being “dedicated” to CAS. This isn’t the 1940s anymore. You don’t need a P-47 to fly around doing gun runs. The A-10 doesn’t need a “1-1” replacement. The argument that the Sandy role requires a low altitude, low survivability replacement because “muh gun scary” is nonsense. If the Sandy role absolutely requires a low altitude show of force to support the CSAR element then you could easily have the HC-130 / CSAR platform carry dozens if not hundreds of air launched effects. Those drones could not only provide increased sensor coverage but also strike targets of opportunity and provide this supposedly important show of force aspect.
