At Sea with the Canadian Navy
From 14 to 18 February 2005, the
Canadian frigate HMCS Calgary participated in anti-submarine exercises with the
US Navy. The exercises were conducted
off the coast of
The purpose of the exercise was to
provide training to American submarine officers who were on a training course
to learn how to be submarine captains.
These trainees had to take a submarine out to sea to search for “enemy”
vessels. HMCS Calgary, along with the

It’s another world inside a ship on anti-submarine exercises. Submarines rely on sonar to find their targets, seeking the sound of an enemy vessel. This means that the quieter the ship is, the harder it is for the submarines to find it. During the exercise, a “sonar quiet” state is enforced. This means no TV or radio, no use of laundry facilities or exercise equipment, and no unnecessary noise. Sailors walk quietly and take care not to slam doors or hatches. (There is an even stricter quiet state, reserved for real wartime situations, in which even the use of the toilet or shower is forbidden.)
It’s not just quiet, it’s also dark. Bright lights can ruin the night vision of the sailors on the bridge. Therefore, the entire ship is lit with dim red lighting that mimics night time conditions—around the clock. Thick drapes blot out any white light spilling from cabin doors. Very few rooms have windows; it’s often difficult to tell what time of day it is. A ship operates around the clock, 24 hours a day. Personnel follow a schedule of 6 hours on duty, 6 hours off—twice a day.
The ship turns sharply in order to evade torpedoes, or to remove itself from an area where it has betrayed its location (such as by firing a weapons system). Bunks are equipped with seat belts so that sailors can avoid being thrown out of bed while sleeping. It is not uncommon for objects to slide off of desks and tables; for this reason, beverages are confined to the wardroom (where meals are eaten) or private cabins.
During the
exercise, several safety precautions are in place. The torpedoes used are a special design that
does not contain explosives. They are
picked up by helicopters after they are fired.
Before one vessel fires on another, the ship has to call a range officer
to ask permission. When
While the ship is steered from the bridge, the captain controls his/her ship from the operations center. This room filled with banks of computer screens and equipment. One row of screens is devoted to personnel who gather information and plot it on displays, tracking the location of possible contacts (other vessels and aircraft). The information they gather is transmitted to the second row, where officers interpret the data and advise the captain. Smaller clusters of equipment are devoted to weapons systems such as torpedoes and missiles.
There are also operators monitoring
NIXIE, a defensive system that is towed behind the ship and designed to create
noise and magnetic field ratings. If an
enemy vessel fires on
The only downside to my tour on
HMCS Calgary was watching Canadian sailors struggling with outdated or broken
equipment. Many of the computer systems on
board ship date back to the 1980s. Some
equipment is even older than that; it was scavenged from other vessels and
installed on HMCS Calgary.
The state of the Canadian military
is a matter of concern. Canadian vessels
are responsible for both the protection of Canadian waters and acting as part
