US Navy support ships are often non-commissioned ships organized and operated by Military Sealift Command. Prior to commissioning, ships may be described as a pre-commissioning unit or PCU, but are officially referred to by name with no prefix. Ships denoted with the prefix "USS" are commissioned ships. 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. The United States Navy has over 480 ships in both active service and the reserve fleet of these approximately 50 ships are proposed or scheduled for retirement by 2026, while approximately 90 new ships are in either the planning and ordering stages or under construction, according to the Naval Vessel Register and published reports.
