On 2 June 2010, Pentagon acquisition chief Ashton Carter announced that they will be removing the SPY-4 S-band Volume Search Radar from the DDG-1000's dual-band radar to reduce costs as part of the Nunn–McCurdy certification process. Due to the SPY-4 removal, the SPY-3 radar is to have software modifications so as to perform a volume search functionality. Shipboard operators will be able to optimize the SPY-3 for either horizon search or volume search. While optimized for volume search, the horizon search capability is limited. The DDG-1000 is still expected to perform local area air defense. This system is thought to provide high detection and excellent anti-jamming capabilities, particularly when used in conjunction with the Cooperative Engagement Capability (CEC). It is, however, not reported if the CEC system will be installed on the "Zumwalt"-class destroyers upon commissioning, but it is scheduled for eventual incorporation in the ship type.
