Those who continue to defend the aircraft carrier have an obvious solution: missile defenses can stop any incoming attacks and keep the carrier relevant for decades. That seems like a reasonable argument, except for one very basic problem: first-grade math tells us it’s flat-out wrong. As I have said on several occasions, U.S. naval planners in the future will face large missile forces aimed at their ships that could very well overwhelm their missile defense platforms. A great example comes from a 2011 report from the Center for Strategic and Budgetary [Assessments], which shows it wouldn’t take much strategic sophistication to beat U.S. missile defenses—just some basic math:
Iran could deploy its land-based ASCMs (anti-ship cruise missiles) from camouflaged and hardened sites to firing positions along its coastline and on Iranian-occupied islands in the Strait of Hormuz while placing decoys at false firing positions to complicate U.S. counterstrikes. Hundreds of ASCMs may cover the Strait, awaiting target cueing data from coastal radars, UAVs, surface vessels, and submarines. Salvo and multiple axis attacks could enable these ASCMs to saturate U.S. defenses…salvos of less capable ASCMs might be used to exhaust U.S. defenses, paving the way for attacks by more advanced missiles.
