12 Carrier Act This bill requires the Navy's naval combat forces to include at least 12 (currently, 11) operational aircraft carriers, effective September 30, 2023. The bill amends the National Defense Authorization Act for Fiscal Year 2016 to eliminate the requirement that the Navy's certification to the congressional defense committees must indicate that the full ship shock trials on the U.S.S. Gerald R. Ford will be conducted before the first deployment of such ship.
