Notes:
On April 6,1998, the Canadian Government announced that four
ex-Royal
Navy submarines of the UPHOLDER class were purchased from Britain (in
an
8 year lease-to-buy schedule).
These submarines were decommissioned from the Royal Navy in 1993 and
were then laid up for several years, after the Royal Navy decided to
focus solely on nuclear submarines as a cost-saving measure. These
submarines are twenty-five years more modern than the OBERON class
submarines that they replace, and they represent a substantial leap in
techology over their predecessors. They use a scaled down hull from the
Royal Navy's successful TRAFALGAR class SSN (nuclear powered attack
submarines).
The subs have undergone preliminary refits at Barrow-in-Furness in
England, and traveled to Canada for further "Canadianization" work once
the Navy was convinced that they were ready. This class of subs is
suffering a large number of teething problems on being reactivated,
possibly exacerbated by the long period of deactivation. As well, the
program to refit them to Canadian requirements is taking longer than
expected due to manpower shortages resulting from
the efforts required to ready ships for Operation Apollo deployments to
the
Middle East. It is not expected that all submarines will be fully
operational until after 2012.
CHICOUTIMI was accepted by the Canadian Navy in Faslane,
Scotland, in a
ceremony in earler October, and was underway to Canada when she
suffered
a serious fire just forward of the bridge. The crew were able to
extinguish
the fire, but several crew members suffered injury from smoke
inhalation,
and one officer later died of his injuries. CHICOUTIMI was towed back
to
Faslane. On October 12, the Navy ordered that all the subs be returned
to port
indefinately while the investigation into the fire on CHICOUTIMI
continues.
It was originally projected that they would be fitted with
fuel cell
technology (Air Independent Propulsion, or AIP) produced by Ballard
Canada. This would have enabled them to remain submerged for extended
periods, possibly allowing
them limited under-ice capabilities. However, this now seems unlikely.
VICTORIA
VICTORIA arrived in Halifax in late October, 2000, and has
since been
refitted considerably. She has been commissioned into the Canadian
Navy, and travelled to Esquimalt, British Columbia, where further work
has been done. VICTORIA has been in and out of refit since arriving on
the West Coast, intermixed with short periods of service.
WINDSOR
WINDSOR has been commissioned, and after completing a portion
of
the refit process, she saw some active service (minus several
capabilities, including that to fire torpedos) to aid in the training
of submariners. During this time, she participated in several cruises
including an exercise with the US Navy. She entered an extended refit
period in 2007 that is expected to last into 2009.
CORNER
BROOK
CORNER BROOK was in refit in 2006, but has since returned to
active service interspersed with several maintenance periods. She still
does not have the capability of firing torpedoes. She has participated
in several exercises, including at least one with the US Navy.
CHICOUTIMI
CHICOUTIMI suffered the aforementioned fire in October 2004,
and did not arrive in Canada until February 2005 when she was
transported on the Eide Transporter.
She entered the graving dock of the Halifax Shipyard in 2005 and
underwent assessment and minor repair and cleanup work during that
time. Upon leaving drydock, she then was laid up at HMC Dockyard for a
period of time until she departed for Esquimalt on the deck of the
semi-submersible heavy lift vessel Dockwise
Tern in April 2009. She arrived in Esqimalt during the last week
of April. In 2010, she is expected to enter an extended refit period
which will return her to service. CHICOUTIMI may have been partially
cannibalized during her layup to keep her sisterships operational.
