Twelve ships of the San Antonio class were proposed, but only eleven were funded. Their original target price was $890 million;[3] as built, their average cost is $1.6 billion.[1] Defense Authorization for Fiscal Year 2015 included partial funding for a twelfth San Antonio-class ship. As of November 2014 nine warships of this class are in service with the U.S. Navy with an additional three ships under construction or authorized.[4]
