The United States Navy

- Arleigh Burke class (60 in commission, one awaiting commissioning, one under construction, at least three more planned)
Modern U.S. frigates mainly perform anti-submarine warfare for carrier strike groups and amphibious expeditionary groups and provide armed escort for supply convoys and merchant shipping. They are designed to protect friendly ships against hostile submarines in low to medium threat environments, using torpedoes and LAMPS helicopters. Independently, frigates are able to conduct counterdrug missions and other maritime interception operations. The U.S. Navy expects to retire and replace its current class of frigates by 2020 as the Littoral Combat Ships are introduced into operation. As in the case of destroyers, frigates are named after naval heroes.
- Oliver Hazard Perry class (19 in commission, 9 in active reserve, 23 decommissioned)
