Anyway... till I get my idea worked out I'll continue to post new versions, and in many cases edited ones of the ships, with Kim Werner's splendid coats-of-arms.
So here are the two variants of the Almirante Williams (ex-HMS Sheffield, F96). The first one shows her as delivered, in 2002, without SCOT radomes, exocet and 30mm guns.
The second shows AW as she appears today, fully modernised and with Barak PDMS abreast her funnel, and a 76 OTO-Melara at the bow.
