October 19, 2007:   The chart below shows the current (as of Summer, 2007) warships serving in the U.S. Navy. CGs are Cruisers (the "G" stands for guided missiles, which all major warships use these days.) CVs are aircraft carriers (an "N" means nuclear powered.) DDGs are destroyers. FFG are frigates. LHA, LHD, and LPD are large amphibious ships that usually carry a battalion of marines, plus helicopters and landing craft. LSDs are smaller amphibs, and carry only about half a battalion. MCM and MHC are mine clearing ships. PC are coastal patrol boats. SSBN are ballistic missile submarines, SSN are attack subs. LCS are Littoral Combat Ships and AKE are combat transports. The American fleet is the largest in the world, and one of the most effective, on a ship-for-ship basis. That combination gives the U.S. Navy an unprecedented portion (about half) of world naval combat power.
