Con này mới định là tuần dương thay thế lớp Tico nhưng huỷ rồi. Nó mà mang 512 VLS thì quá bằng huỷ diệt

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 cancelled in 2010; its mission is to be taken by
Flight III Arleigh Burke–class destroyers instead.

History
Background
In the early 1990s, the U.S. Armed Forces had to respond to new threats and budgets after the end of the
Cold War. The U.S. Navy's response was the
Surface Combatant for the 21st Century (SC–21) program. This envisaged a destroyer called DD–21 and a planned cruiser called CG–21. Budget cuts in November 2001 meant that SC–21 became the less ambitious Future Surface Combatant program. The DD-21 was renamed the DD(X), which was later named the
Zumwalt-class destroyer. By April 2002, the DD(X) was to be the "foundation" for a family of surface combatants, including CG(X) as the successor to the CG–21. The
Ticonderoga class cruisers will reach their retirement age of 35 years between 2021 and 2029, although the U.S. Navy may use upgrades to extend their lives to 40 years.

Next Generation Cruiser
The CG(X) program was announced on 1 November 2001. An initial requirement for 18 CG(X) was raised to 19 under the plan for a 313-ship Navy in 2005.
A reassessment in 2007 suggested splitting the CG(X) into two classes, fourteen Zumwalt-sized "escort cruisers" and five 23,000 ton ballistic missile defense (BMD) ships. There was political pressure for some or all of these ships to be nuclear powered, which would have given them the hull classification symbol of CGN(X).[

The FY2009 budget called for procurement of the first CG(X) in 2011, and the second in 2013. On 1 February 2010, U.S. President Barack Obama unveiled his proposed budget for FY2011. This budget called for, among other things, canceling the entire CG(X) program.

The program was Cancelled in the 2010
Quadrennial Defense Review.
[3] The CG(X)'s mission will instead be performed by
DDG-51 Flight III destroyers, after the U.S. Navy concluded that the ships could rely on off-board and space-based sensors and so did not need a radar bigger than the DDG could carry.
