The Constellation-class multi-mission guided-missile frigates of the United States Navy are based on the European multipurpose frigates (FREMM), already in service with the French and Italian navies. Constellation follows the modular but problematic littoral combat ships of the Freedom and Independence classes. The U.S. Navy announced the FFG(X) frigate project in the United States Department of Defense's Request For Information (RFI) on 10 July 2017.
The Navy selected five shipbuilders to present their ideas for a prospective design for the proposed twenty FFG(X) guided-missile frigates. On 30 April 2020, the Navy announced that Fincantieri Marinette Marine had won the contract with a modified design based on the FREMM, designed by Naval Group and Fincantieri. The project was later renamed FFG-62 program after the lead ship of her class.
