Request for Information 127mm ammunition

Canada’s defence policy, “Strong, Secure, Engaged” (SSE), has committed to investing in 15 Canadian Surface Combatant (CSC) ships. These ships will be Canada’s major surface component of maritime combat power. With its effective warfare capability and versatility, it can be deployed rapidly anywhere in the world, either independently or as part of a Canadian or international coalition. The CSC will be able to deploy for many months with a limited logistic footprint.

The CSC will be able to conduct a broad range of tasks, including:

• Delivering decisive combat power at sea;
• Supporting the Canadian Armed Forces, and Canada’s Allies ashore;
• Conducting counter-piracy, counter-terrorism, interdiction and embargo operations for medium intensity operations; and
• Delivering humanitarian aid, search and rescue, law and sovereignty enforcement for regional engagements.

The acquisition is for 15 ships to replace both the retired Iroquois-class destroyers and the serving Halifax-class frigates. The construction of the first CSC vessel is expected to begin in 2023/2024.
