This report provides background information and issues for Congress on the Navy's Littoral Combat Ship/Frigate (LCS/FFG(X)) program, a program to procure a total of 40, and possibly as many as 52, small surface combatants (SSCs), meaning LCSs and frigates. A total of 29 LCSs have been procured through FY2017. For FY2018, the Navy is requesting the procurement of two more LCSs, which would be the 30th and 31st. The program presents several oversight issues for Congress. Congress's decisions on the LCS/FFG(X) program will affect Navy capabilities and funding requirements, and the shipbuilding industrial base.
