Carrier defense depends on mobility, stockpiles, and layers

Does heavy Patriot expenditure mean US carrier groups are more vulnerable to air attack than assumed?

They remain vulnerable, but mobility, fighters, seekers, replenishment, and layered defenses make the problem different from protecting fixed land targets; adequate missile inventories still matter.

A carrier group can move, withdraw when magazines run low, replenish aviation weapons, and use fighters to engage threats farther from the ships. Attacking that moving target demands course correction and suitable seekers, while an airfield remains at known coordinates. In the example, an equal salvo against each need not produce the same number of missiles that actually threaten the target. The answer treats Patriot and Standard Missile stockpile depth as a concern while distinguishing the two weapons' characteristics. Exact interception effectiveness and the reasons for recent expenditure are not publicly established in the discussion. A shortage of short-range defences against drones would imply a different lesson from repeated failures against ballistic missiles. Combat experience can change both attacking and defensive systems, so the answer avoids treating one war's results as a permanent measure of carrier vulnerability.
