Notes:
This class
of destroyers was a follow-on to the ST. LAURENT class of ASW destroyer
escorts of the 1950's. They were built late enough to incorporate the
helicopter
hangar retrofitted to the ST. LAURENTs, along with a VDS. HMCS NIPIGON
remained in the fleet as a trials ship for the ETASS Mod 5 gear until
paid
off in 1998. ETASS is a continuing project to improve the towed array
sonar
gear used by the Canadian Navy, and the ETASS Mod 4 was the precursor
to
CANTASS (Canadian Towed Array Sonar System). In 1982 NIPIGON underwent
a DELEX (DEstroyer Life EXtension) refit, which replaced various
combat,
radar, and weapon systems. ANNAPOLIS followed in 1984. NIPIGON
was the last of the steam-powered frigates to serve the Canadian Navy.

(as
indicated by the stern cutout). ('85) DND photo.
