Ladies and Gentlemen, HMS Speedy:
I seem to recall before they bought more Leanders the RNZN considered a serious
conversion of their Type 12 Otago. I am sure I have seen a drawing but cannot remember
where? It would make an interesting add on to my UK frigates stuff.
The Brazilian "Niteroi" class frigates started life as the Vosper Thorneycroft
Mark 10 design in the late 1960s.
Many years ago I was looking at a Vosper brochure and it contained a small
artwork of a version of this ship armed with Seadart instead of the forward
4.5" gun. I have never been able...
Some interesting Bell and VT designs came out in the 1960's, I dare say not that practicable. However it is interesting to see how the defense industry saw the future, very often the future we describe, ends up the future we have.
