Frigate USS Clark[ e-boek]

The ships of the Oliver Hazard Perry-class were designed in the United States in the mid-1970's as general-purpose escort vessels. They were inexpensive enough to be bought in large quantities and replace older ships. Meant to protect amphibious landing forces, supply and replenishment groups, and merchant convoys from submarines, they also became part of battleship-centric groups and aircraft battle/strike groups.
