Which aircraft is not primarily used for Close Air Support (CAS)?

The F-22 is primarily designed for air superiority and has advanced capabilities in air-to-air combat. While it is equipped to perform various roles, including some ground attack missions, it is not specifically optimized for Close Air Support (CAS). CAS involves engaging enemy forces in close proximity to friendly forces, necessitating an aircraft that excels in low-altitude operations and has the ability to deliver precision strikes with minimal collateral damage.

In contrast, the A-10 is a dedicated CAS platform, specifically designed for targeting ground troops with its gun and a variety of munitions. The FA-18 and F-16 also have strong CAS capabilities, with features that allow them to perform effectively in that role. However, the F-22 remains focused on air dominance and stealth, which are secondary priorities for CAS missions, marking it as the least suitable option compared to the others listed.
