The CG(X) program, also known as the Next Generation Cruiser program, was a United States Navy program to replace its 22 Ticonderoga class cruisers after 2017. Original plans were for 18–19 ships, based on the 14,500 ton Zumwalt class destroyer but providing ballistic missile defense and area air defense for a carrier group. The program was canceled in 2010; its mission is to be taken by Flight III Arleigh Burke–class destroyers instead.
