Could a ship double its Aegis system so that it can handle twice as many missiles?
Short answerAegis has growth potential, but major gains require sustained funding and a new hull architecture with better power, cooling, and computing support.
NotesAegis still has room to improve, but legacy Ticonderoga and Arleigh Burke architectures restrict what upgrades can exploit. The combat system remains an international leader, though decades of limited investment allowed other systems to enter the same broad performance range. A genuinely larger step would need a ship designed around modern power, cooling, and computing support. Allied systems such as the Type 45's can contribute complementary strengths, but they do not remove the need for a new American hull architecture.
