(SPY-3 & SPY-4) is to be installed only on the . With the development of the AN/SPY-6 Air and Missile Defense Radar (AMDR), it seems unlikely the DBR will be installed on any other platforms, as it is on the DDG-1000 class, or in total, as it is on Gerald R. Ford. The Enterprise Air Surveillance Radar (EASR) is a new design surveillance radar that is to be installed in the second Gerald R. Ford-class aircraft carrier, , instead of the Dual Band radar. The s starting with LHA-8 and the planned s will also have this radar. The AN/SPY-6 AMDR was originally proposed to be installed in the hull of DDG-1000 type under the CG(X) program. However, the CG(X) program was canceled due to cost growth. The AMDR has continued in fully funded development for installation on the Arleigh Burke class destroyer Flight III ships, with plans to be also installed on Flight IIA ships. However, a smaller than optimally planned aperture of , the AMDR for the Flight III ships is to be less sensitive than the variant that had been planned for CG(X). A study to place the AN/SPY-6 on a DDG-1000 hull was done with the aperture primarily for Ballistic Missile Defense (BMD) purposes. In that the DDG-1000 does not have an Aegis Combat System, as does the DDG-51 class ships, but rather the Total Ship Computing Environment Infrastructure (TSCEI), the Radar/Hull Study stated: Common Display System The ship's Common Display System is nicknamed "keds": Sailors operate keds via trackballs and specialized button panels, with touchscreens option to the interface. The technology array allows sailors to monitor multiple weapons systems or sensors, saving manpower, and allowing it to be steered from the ops center. Sonar A dual-band sonar controlled by a highly automated computer system will be used to detect mines and submarines. It is claimed that it is superior to the Arleigh Burke classs sonar in littoral ASW but less effective in blue water/deep sea areas. Hull-mounted mid-frequency sonar (AN/SQS-60) Hull-mounted high-frequency sonar (AN/SQS-61) Multi-function towed array sonar and handling system (AN/SQR-20) Although Zumwalt ships have an integrated suite of undersea sensors and a multi-function towed array, they are not equipped with onboard torpedo tubes, so they rely on their helicopters or ASROC missiles to destroy submarines that the sonar picks up. Propulsion and power system The Zumwalts use an Integrated Power System (IPS), a
