First-in-class USS Constellation (FFG-62) is in production in Marinette, Wisconsin, and sister ships USS Congress (FFG-63) and USS Chesapeake (FFG-64) are under contract.

The Constellation class will have multi-mission capability to conduct air warfare, anti-submarine warfare, surface warfare, electronic warfare, and information operations. Specifically, the FFG-62 class includes an enterprise air surveillance radar, Baseline Ten AEGIS combat system, a Mk-41 Vertical Launch System (VLS), communications systems, MK-57-gun weapon system countermeasures, and added capability in electronic warfare and information operations with design flexibility for future growth.

FMM on April 30, 2020, was awarded the contract for the design, construction and delivery of the first ten Constellation Class Frigates.

Program Executive Office Unmanned and Small Combatants (PEO USC) designs, develops, builds, maintains, and modernizes the Navy’s expanding family of unmanned maritime systems, mine warfare systems and small surface combatants.

Guided-Missile Frigate

The US Navy announced it has exercised the option to have Fincantieri U.S. subsidiary, Marinette Marine (FMM), build the third Constellation-class guided-missile frigate, USS Chesapeake (FFG-64). The option value stands at approximately 536 million dollars.

This announcement follows last month’s successful design review of the first-in-class USS Constellation (FFG-62), which is nearing the start of construction.

The Constellation program was awarded to FMM in 2020, through a contract for the lead frigate and 9 option ships. The contract, including post-delivery availability support and crew training, has a cumulative value of 5.5 billion dollars. Under the same program, the U.S. Navy plans to build 10 additional vessels, for a total of 20 units.

Fincantieri succeeded in such a high-profile tender, distinguishing itself among several major U.S. shipyards thanks to a project considered as the most innovative and cutting-edge. The Group’s proposal is based on the FREMM frigate platform, globally recognized as the most technologically advanced, and the backbone of a 10-unit program for the Italian Navy which Fincantieri is currently completing.

Furthermore, the upgrade of Fincantieri U.S. shipyards is nearly completed, enabling the subsidiary to build two frigates each year.

FMM is the spearhead of Fincantieri Marine Group (FMG), which controls two other shipyards also located in the Great Lakes (Wisconsin) – Fincantieri Bay Shipbuilding and Fincantieri Ace Marine. The company serves commercial and government customers in the U.S. FMM is committed to the Littoral Combat Ships program for the U.S. Navy and the Multi-Mission Surface Combatants (MMSC) program for the Kingdom of Saudi Arabia as part of the U.S. Foreign Military Sales plan.
