The CGX cruiser is the Navys planned replacement for its 22 existing Ticonderoga CG-47 class Aegis-equipped cruisers, which are projected to reach retirement age between 2021 and 2029. The CG-47s are multimission ships with an emphasis on air defense. The Navy wants the CGX to be a multimission ship with an emphasis on air defense and ballistic missile defense BMD. The Navys planned 313-ship fleet calls for a total of 19 CGXs. The Navy would like to use the design of its new DDG-1000 destroyer as the basis for its planned CGX cruiser. Ships based on other hull designs are possible. Nuclear propulsion is an option being studied for the CGX.
