List of current ships of the United States Navy
The United States Navy has approximately  ships in both active service and the reserve fleet; of these approximately  ships are proposed or scheduled for retirement by , while approximately  new ships are in either the planning and ordering stages or under construction, according to the Naval Vessel Register and published reports. This list includes ships that are owned and leased by the US Navy; ships that are formally commissioned, by way of ceremony, and non-commissioned. Ships denoted with the prefix "USS" are commissioned ships. Prior to commissioning, ships may be described as a pre-commissioning unit or PCU, but are officially referred to by name with no prefix. US Navy support ships are often non-commissioned ships organized and operated by Military Sealift Command. Among these support ships, those denoted "USNS" are owned by the US Navy. Those denoted by "MV" or "SS" are chartered. Current ships include commissioned warships that are in active service, as well as ships that are part of Military Sealift Command, the support component and the Ready Reserve Force, that while non-commissioned, are still part of the effective force of the US Navy. Future ships listed are those that are in the planning stages, or are currently under construction, from having the keel laid to fitting out and final sea trials. There exist a number of former US Navy ships which are museum ships (not listed here), some of which may be US government-owned. One of these, , a three-masted tall ship, is one of the original six frigates of the United States Navy. It is the oldest naval vessel afloat, and still retains its commission (and hence is listed here), as a special commemoration for that ship alone. Current ships
