The Oliver Hazard Perry-class frigate is a class of guided-missile frigates that were primarily used by the United States Navy. Designed for anti-submarine warfare, these ships are equipped with advanced radar and sonar systems, allowing them to detect and engage enemy submarines and surface vessels. The class was named after Oliver Hazard Perry, a naval commander in the War of 1812. These frigates were built between 1977 and 1996, with a total of 51 ships constructed. They feature a sleek design and are capable of operating in various roles, including escorting larger vessels and conducting independent missions. The Perry-class has been widely exported and remains in service with several navies around the world.
