US Figs have pretty much been left un-armed with missiles. They should now just be termed Fast Frigates (FF). Many Perrys have been decommissioned and some have been transferred to other countries.
In addition to the single-armed launcher equipped Perrys, the twin-armed launcher equipped Aegis cruisers have been decommissioned, leaving just the VLS-equipped versions in service.
The Aussies have also removed the launcher from their Perrys (Adelaides ?), but they have added other offensive capabilities including VLS cells. The RoC have added additional guns. I'm not sure what the Spaniards have done with theirs.
To keep this subject on modeling -- I just received a set of decals from Iron Shipwright for the short-hulled Perrys. This set used to be in the ISW resin kit which has now been dicontinued. The set includes hull numbers and names for all the short-hulls as well as helo deck & VERTREP markings. Also missile foul-lines, hangar door markings, and bridge & helo control windows (with windshield wipers). The Academy kit decals only allow the Perry and the deck markings are not nearly as nice.
