A side AU project, showing an improved and up-armed Freedom-class LCS as the mainstay frigate of the US Navy to replace the Oliver Hazard Perry-class. Like the LCS irl, the vessels are named after US cities (often reusing the names of decommissioned Los Angeles-class submarines or Austin-class LPDs) - with the exception of the first two vessels (the USS Freedom and USS Independence). Although smaller than other frigates used by global navies (such as the Type 26 of the Royal Navy, Russian Admiral Gorshkov-class, or French Aquitaine-class) they form a core part of the USN fleet worldwide alongside the Arleigh Burke-class destroyers and Ticonderoga-class cruisers.
These vessels are up-armed with a Mk41 VLS (capable of firing RIM-162A ESSM missiles), 8 Harpoon missiles located amidships, a 5 inch Mk45 main gun, Phalanx CIWS over the rear hangar, and 2 twin Mark 50 torpedo launchers. They have an increased complement of around 105 personnel (less than the OHP-class they replace) and can carry up to two MH-60 Seahawk helicopters, as well as numerous small boats/USVs launched from the modular mission bay in the stern alongside the Raytheon DART towed sonar system.
