The SPQ-9A on Ticonderoga-class cruisers and the SPS-67 on Arleigh Burke-class destroyers are being replaced by the SPQ-9B. It provides twice the range compared to the SPQ-9A and improved range resolution. This replacement is being done as a part of the United States Navy's cruiser modernization and destroyer modernization programs to extend the life of the existing ships. The new SPQ-9B will be a part of the Mk 160 Mod 11 Gun Computer System of the Mk 34 Gun Weapon System. The first operational evaluation of the SPQ-9B was on in October 2002. It is to be installed on CVN-68, LPD-17, CG-47, WMSL-750, LHD-1, and LHA-6 ship classes. The system is X-band and the antenna consists of dual planar arrays mounted back-to-back under a radome. Flight III Arleigh Burke-class destroyers are also planned to have the SPQ-9B. ==Gallery==
