I want to know the answer to the following question:
What protects the outer layer?
All the background I'm provided with is that "If an attacker is able to penetrate this layer, then the next layers would come from the surface-to-air missiles carried by the carrier's escorts; the area-defence missiles, such as the RIM-67 Standard, with a range of up to 100 nmi, and the point-defence missiles, like the RIM-162 ESSM, with a range of up to 30 nmi.". Is that enough to answer the question?
Answer: no
