Rus is indeed a lot behind.
the SPY3 & the new volume search radar will have a common backend thing to integrate the two front ends (search and guidance). so really seamless levels of integration is to be expected.
pretty bleeding edge this thing…cost obviously is not a criteria, *intimidation* certainly is !

The SPY-3 is an active phased array X-band radar designed to meet all horizon search and fire control requirements for the 21st century fleet. The Multi Function Radar combines the functions provided by more than five separate radars currently aboard Navy combatant ships.

The Dual-Band Radar on the DD(X) will consist of the SPY-3 Multi-Function Radar, which will operate in X-band frequencies, and a lower-frequency S-band Volume Search Radar. The SPY-3 is designed to search close around the ship, moving out to the horizon rapidly to detect fast, low-flying aircraft and cruise missiles. It also will detect submarine periscopes. The SPY-3 will operate in conjunction with the Volume Search Radar to provide seamless, hemispheric search coverage around the ship.
Written responses to ISR questions from the Navy DD(X) program office at Naval Sea Systems Command in Washington, D.C., state that the Volume Search Radar “is designed to search the hemispheric volume above the horizon for higher-flying threats, limited area air defense, and general situational awareness.” It will hand over targets to the SPY-3 for precision tracking. The SPY-3 will provide semi-active missile illumination, which means that it can guide shipboard surface-to-air missiles to intercept incoming threat aircraft or anti-ship missiles.
What is unique about the Dual-Band Radar is that the SPY-3 and the Volume Search Radar will share a common back end — a common processing and control suite. “The common back end for the Dual-Band Radar will be smaller and lighter and will require less logistics than having separate signal and data-processing equipment for each frequency as in legacy radar systems,” the DD(X) program office said.
“It also will enable the two radar apertures to operate in a coordinated fashion at the waveform level to maximize use of radar resources. The common back end will have modern signal and data-processing technologies and sophisticated [software] algorithms to enable the radar to operate in natural and man-made environments in the littorals,” the office said.
Raytheon says the dual-band approach avoids multiradar, target track correlation problems; reduces software development and maintenance; and provides improved performance in adverse environments.
