# CG(X) Cruiser Program The CG(X) program was a United States Navy initiative to develop a new class of guided-missile cruisers intended to replace the aging Ticonderoga-class cruisers. Officially designated as Maritime Air and Missile Defense of Joint Forces (MAMDJF), the program was conceived in the early 2000s as part of a broader effort to modernize the Navy's surface fleet. ## Background and History The program emerged from the Navy's need to upgrade its cruiser fleet, which had been in service since the 1980s. The Ticonderoga-class cruisers, while versatile, were becoming obsolete and required replacement. The CG(X) program aimed to create a next-generation cruiser that would incorporate advanced Aegis Ballistic Missile Defense (BMD) capabilities and other cutting-edge technologies. ## Technical Specifications and Design ### Size and Propulsion * **Size:** Initially planned for two variants: large (26,000 tons, nuclear propulsion) and small (14,500 tons, conventional propulsion). The large variant was intended to serve as an escort for aircraft carriers. * **Propulsion:** The large variant was to use nuclear propulsion, while the small variant would use conventional propulsion. The nuclear option was considered for its extended range and endurance. ### Armament * **Missile Systems:** The CG(X) was designed to carry advanced missile systems, including: * **SM-3 Block IA/IB and II/IIA:** For intercepting ballistic missiles in the midcourse phase. * **Kinetic Energy Interceptor (KEI):** For boost-phase defense against ballistic missiles. * **SM-6 ERAM (Extended Range Active Missile):** For air defense and anti-ship roles. * **Advanced Gun Systems:** The program included plans for a 155mm Advanced Gun System (AGS) and an experimental Electromagnetic Railgun (EMRG), offering longer range and higher velocity than conventional guns. * **Air Defense:** Integration of the Standard Missile family for anti-aircraft and anti-missile defense. ### Radar and Sensors * **Advanced Radar:** The CG(X) was to be equipped with a next-generation radar system featuring 30-31 megawatts of power, significantly more powerful than the AN/SPY-1 radars on existing Aegis ships. This radar was intended to support BMD operations and provide enhanced air surveillance. * **Power Requirements:** The high-power radar necessitated nuclear propulsion to provide sufficient electrical power. ## Program Status and Cancellation The CG(X) program was formally canceled in 2010 as part of a broader restructuring of the Navy's shipbuilding plans. The cancellation was announced alongside the termination of several other programs, including the DDG-1000 Zumwalt-class destroyer program. The decision was driven by escalating costs, technical challenges, and shifting priorities within the Department of Defense. ## Legacy and Impact Although the CG(X) program was ultimately canceled, its legacy includes valuable lessons learned in naval architecture, missile defense integration, and the development of advanced technologies like the Electromagnetic Railgun. The program also influenced subsequent Navy initiatives, such as the development of the Flight III Arleigh Burke-class destroyers and continued research into next-generation surface combatants. ## Key Figures and References * **Ronald O'Rourke:** Author of Congressional Research Service reports on Navy shipbuilding and the CG(X) program. * **Philip Coyle:** Interviewed in PBS Frontline's 'Missile Wars' documentary, providing insights into missile defense policy. * **Zachary M.
