An AESA radar contains many tiny transmitter-receiver modules that require rapid, precise computer adjustment. Their performance depends on correct control and careful maintenance. Naval installation also requires the radar and its supporting systems to operate in a saltwater environment. These integration demands help explain why technology can take years to reach a particular ship class. The funding explanation also points to post-Cold War expectations that major naval warfare was unlikely, followed by competing demands during the War on Terror. Both the technical work and the willingness to fund it affected the pace of adoption in this account.

Why AESA radar needs more than a new antenna
AESA adoption depends on module control, maintenance, saltwater integration, and funding for the shipboard systems that support the radar.
