Hi John, already did that on all the Vosper, Vosper Thornycroft, BAE Systems Surface Ships etc etc sites. Nix!
I suspect it may have been a design offered for an Request To Tender but not accepted and never built
Nevertheless, have a go and see if you find something I overlooked👍
MPC 85 means; Multi Purpose Corvette 85m.
Cheers, Doug 😎
PS also worked on the VT Mk10 Frigates also shown in your link, the Niteroi Class for Brazil. Niteroi is the name of the town on the other side of the bay from Rio. At the other end of the bridge connecting the two towns is the Brazilian Navy submarine base where I also worked on some Tupi class submarines, German Type 209s. Good times 😉
PPS I'm still suspicious of that curious stern! Never seen anything like that afloat!!
