ARLINGTON, Va. — The U.S. Navy has invested funding toward building the land-based engineering test site for the Constellation-class guided-missile frigate (FFG).  

The Navy’s Supervisor of Shipbuilding, Conversion, and Repair, Bath, Maine, has awarded to Fincantieri Marinette Marine, Marinette, Wisconsin, a $76.7 million firm-fixed-fee contract modification “for procurement of long-lead time material for the land-based engineering site for the Constellation-class frigate,” the Defense Department contract announcement said. 

The land-based test site to be built in Philadelphia will be used to test the propulsion system and other machinery of the frigate design to reduce risk and identify and fix problems before they would be manifest in the lead ship of the class.  

The land-based engineering test site was mandated by the Fiscal 2021 National Defense Authorization Act as an expression on Congressional intent regarding solving engineering problems as construction proceeds.   

The construction of the U.S. Navy’s next class of guided-missile frigates officially began Aug. 31 with the first steel for the ship cut in a small ceremony at the Fincantieri Marinette Marine Shipyard in Marinette, Wisconsin.  

The future USS Constellation (FFG 62) will be the lead ship of a class of at least 20 frigates and is slated for delivery in 2026. The hull of the frigate is be based on the Italian FREMM-class frigate and will be equipped with proven weapons and combat systems.   

Work on the contract is expected to be completed by October 2025.
