By the Numbers
Future US Navy Vessels
The U.S. Navy has a pipeline of nearly 100 vessels either under construction or on order.
The U.S. Navy at present has more than 490 vessels in both active service and the reserve fleet, from aircraft carriers to berthing barges. Below are charts showing the pipeline of nearly 100 additional vessels that are currently either under construction or in the planning and ordering stages.
The U.S. Navy often refers to these ships as "pre-commissioning unit" (PCU), used informally as a nonofficial ship prefix. Some of these ships may have already been delivered to the Navy but are not actively commissioned.
While these ships have been ordered by the U.S. Navy, their keels have not yet been laid, meaning they are not yet considered “under construction”.
