The Oliver Hazard Perry guided missile frigates are one of the most numerous warships classes built since World War II. The first ships entered service in the 1980s, but many still serve under the flags of other nations, all of whom are intensely interested in keeping these vintage ships as effective as possible.
With the last of the ships scheduled to leave US service by the fall of 2015, even more Perrys — commonly known as FFGs, or “figs” — will become available for foreign transfer and hence, in need of upgrades.
