Oldgateboatdriver said:Yes, HT, Stoney is correct.
It is the first HMCS Algonquin (ex- HMS Valentine). Originally she was a V-class destroyer, but then was converted in 1953 into an ASW frigate mostly modelled on the type 15 standards of the RN. It was a home made re-design and she became one of a kind for the rest of her life.
Oldgateboatdriver said:That's because the VDS experiments were carried onboard HMCS CRUSADER, not onboard any Prestonian class frigate.
What you possibly had in mind, for experiments onboard the Prestonian's, was the Helicopter trial onboard HMCS BUCKINGHAM.
