CG(X)

From Wikipedia, the free encyclopedia

The CG(X) was a planned ship design of the U.S. Navy. It was called a cruiser, but it was to use the same hull form of, and be developed from, the DD(X). The CG(X) resulted after a massive cut to the SC21 (21st Century Surface Combatant) program.

While the planned CG21 was much bigger than the DD21, the CG(X) was the same, but in a different configuration. Essentially a DD(X) hull with more VLS in place of the gun system.

This would have marked yet another lowering of previously much larger difference between cruisers and destroyers. (see also 1975 ship reclassification). The program was rumored to be cancelled in 2006, when the first two ships of the related DD(X) program were authorized as "technology demonstrators." (See USS Zumwalt (DDG-1000) and Zumwalt class destroyer)

It was intended to replace the existing Ticonderoga-class Aegis cruisers, with improved Missile Defense and Air Warfare capability. It will share with DD(X) a common propulsion architecture and a stealthier hull form. This hull form will contain an integrated all-electric power system that is more efficient and survivable than today's propulsion systems, and provides more power capacity for future weapons.

[edit] Development

The New York Times on December 5, 2005, reported that the Navy plans to build 19 CG(X) ships for missile-defense. The CG(X) was rumored to be cancelled in 2006.
