The ''Oliver Hazard Perry'' class came in two forms, the short-hulled and long-hulled, with the ''Santa María'' class being of the later with additional beam to allow for more top weight for future modifications. The class came in two batches, with the first four being of batch one and the final two of the second. The first batch of ships have a
