Notes:
The RESTIGOUCHE
class was a natural follow-on to the original ST. LAURENT class, and
indeed
only had a few minor improvements. The most noticeable were the
replacement
of the forward 3"/50 with a 3"/70, and the presence of a fire control
director
atop the bridge superstructure. In order to see over the new gun mount,
the bridge was raised one full deck higher than on the previous ships.
The Vickers 3"/70 Mk.6 was developed by the Royal Navy and fitted to
their TIGER
class cruisers. The RCN was the only other customer. It was designed to
fire up to 120 rounds per minute per barrel (although this was limited
in service to 90 to reduce barrel wear), and the mazazine for this gun
was referred to as the "bottling plant" for its handling of ammunition.
It took several years to work out the bugs in this weapon, however.
In the late 1960s, four ships of this
class
were refitted to what is known as the Improved RESTIGOUCHE (IRE) class,
which replaced the aft 3"/50 gun with an octuple ASROC launcher and the
old mast with a new, taller lattice mast. The stern was also altered in
order to accommodate a new variable depth sonar. The ships that did not
receive this refit were paid off into Category "C" Reserve soon
afterward, during the manpower
shortages of the early- to mid-1970s. Of these, CHAUDIERE was used as a
parts hulk and donated her bow to KOOTENAY after a collision, COLUMBIA
became a dockside engineering training platform (with no-thrust wheels
replacing her propellers), and ST. CROIX had her weapons and propellers
removed and her machinery spaces converted into classrooms.
The IRE ships remained in
service
until the mid- to late 1990s. In 1969, KOOTENAY suffered the Canadian
Navy's worst peacetime accident when her starboard
gearbox exploded,
killing 9 crew members. In 1989, she collided with freighter and
suffered damage to her bows. In August of 1990, TERRA NOVA was hastily
(and temporarily) re-equipped and deployed as part of Canada's
contribution to Coalition forces during the Gulf War. RESTIGOUCHE was
similarly refitted for possibly service in the Persian Gulf, but did
not deploy there until after the end of hostilities.
The remaining four of these ships were paid off during the 1990s, as
the new HALIFAX class frigates entered service. TERRA NOVA was the last
to go in 1997, after 38 years of service. After being paid off, TERRA
NOVA appeared in the movie "K-19 - The Widowmaker" starring as a USN
destroyer.
