The Early Cold War
Rebuilding and Transformation

The Canadian navy's main Cold War mission was anti-submarine warfare, as it had been in the two world wars. It sought to build a force of ships, personnel, and facilities to fulfill this mission, as well as to pursue other national objectives like sovereignty protection.

Twin 3-Inch Naval Gun and Mount

Guns like this twin 3-inch weapon were fitted to most of Canada's warships built during the Cold War.

This particular version combined two guns on a power-driven mount covered by a housing that helped protect the complex weapons from the elements. The mount, requiring a crew of 12, had a rate of fire of approximately 50 rounds per minute per gun, and could be used against aircraft or surface targets including ships. This gun was installed in the forward gun mount of HMCS Qu'Appelle, a Mackenzie class destroyer launched in 1962.
