Oliver Hazard Perry-class frigate

The Oliver Hazard Perry class is a class of guided-missile frigates named after Commodore Oliver Hazard Perry of the Battle of Lake Erie, also known as the OHP or FFG-7 class. Designed in the United States in the mid-1970s by Bath Iron Works with the naval architects Gibbs and Cox as inexpensive general-purpose escorts that could be bought in large numbers, they were the low-capability half of the high-low fleet plan beside the Spruance-class destroyers. Fifty-five were built in the United States, fifty-one for the US Navy and four for the Royal Australian Navy, with more built in Taiwan, Spain and Australia. The first US Navy ship entered service in 1977 and the last, USS Simpson, was decommissioned on 29 September 2015, and many were transferred to other navies. They were the second US Navy surface ships with gas turbine propulsion.
