Second World War
Battle of the Atlantic  - Weapons and Technology

Combatants in the battle of the Atlantic relied on weapons and technology to attack the enemy, to defend themselves, to communicate, and to rescue friends and foes.

"Pom-Pom" Anti-Aircraft Gun, HMCS Kamloops

The pom-pom anti-aircraft gun, so-called because of its characteristic sound when firing, was fitted to most Canadian corvettes during the Second World War.

Designed to counter low-flying aircraft, the pom-pom could also be used against surfaced submarines. Canadian manufacturers built hundreds of these guns during the war. Dominion Bridge Company manufactured this one in 1942, while the Canadian Locomotive Co. of Kingston, Ontario, made the mounting. Both were fitted to the corvette HMCS Kamloops, which appeared in the 1943 film Corvette K-225.
