Another addition to the "Gerald R. Ford" class is an integrated active electronically scanned array search and tracking radar system. The dual-band radar (DBR) was being developed for both the "Zumwalt"-class guided missile destroyers and the "Gerald R. Ford"-class aircraft carriers by Raytheon. The island can be kept smaller by replacing six to ten radar antennas with a single six-faced radar. The DBR works by combining the X band AN/SPY-3 multifunction radar with the S band Volume Search Radar (VSR) emitters, distributed into three phased arrays. The S-band radar was later deleted from the "Zumwalt" destroyers to save money.
