Strategic Tanker Transport Capability project

Project summary

The Government of Canada is acquiring a new fleet of aircraft to replace the CC-150 Polaris. Known as the Strategic Tanker Transport Capability (STTC), this new fleet will conduct multiple tasks such as in-flight refuelling of other aircraft, military personnel and cargo airlift, medical evacuations, and strategic transport of Government of Canada officials.

This new aircraft will improve the flexibility, responsiveness, interoperability with allied nations, communications security, and self-protection of the Royal Canadian Air Force’s current fleet.

The project will acquire an in-service support solution for the aircraft, as well as infrastructure to house and maintain the fleet at the main operating base. Additionally, the project will provide a training and simulation capability to prepare and maintain crew readiness.

Benefiting Canadian Industry

Industrial and regional benefits:

The Industrial and Technological Benefits (ITB) Policy, including the Value Proposition (VP), applies to the STTC procurement and seeks to leverage economic benefits for Canada equal to the value of the contracts. Through the ITB Policy, the STTC Project will leverage investments and business activities in support of Canada’s VP pillars, including:

  • Defence Sector;
  • Supplier Development;
  • Skills Development and Training;
  • Research and Development; and
  • Exports.

Additionally, ISED has identified specific key industrial capabilities that align with the STTC program, including, Aerospace Systems and Components, Defence Systems Integration, Advanced Materials, ISS, Training and Simulation and Clean Technologies. ISED will motivate business activities into key industrial capabilities through the selected VP requirements.

The Aboriginal Participation Component (APC) is a mechanism designed to facilitate the Government of Canada’s commitments of advancing aboriginal socio-economic development through federal contracting opportunities, and it was introduced to suppliers through industry engagement opportunities. The APC is a portion of the value of a contract that is set aside for aboriginal participation, which can be direct or indirect (or both).

Project costs

Project costs

  • The project cost is currently valued between $1 billion – $4.99 billion. Project costs will be refined based on industry feedback as the project advances.


There are some risks associated with the schedule, namely the volume of work to be accomplished may delay near-term milestones, and infrastructure work may lag equipment delivery. We continue to monitor the situation closely and will update the project page should information change.
