CP-140 Aurora fleet modernization and life extension

Project summary

The Government of Canada is modernizing its fleet of 14 Aurora aircraft. The Aurora Incremental Modernization Project (AIMP) involves 23 individual projects to acquire, integrate and install new mission systems and sensors onto the CP-140 for intelligence, surveillance and reconnaissance. This project is being executed in a phased approach with four blocks; blocks 1, 2 and 3 are complete, and block 4 is in the implementation phase.

The Government of Canada is also extending the life of the Aurora fleet. The Aurora Structural Life Extension Project (ASLEP) involves replacing wings and horizontal stabilizers on the aircraft. It will extend the operational life of the CP-140 Aurora fleet to 2030. This project is currently in the implementation phase.

The Aurora fleet is Canada’s primary airborne intelligence, surveillance, and reconnaissance aircraft. The Aurora provides a full range of maritime, littoral and overland surveillance capabilities for domestic and deployed missions in support of Canadian sovereignty and international objectives, as well as anti-surface and anti-submarine warfare. It has been modernized with a world-class integrated mission suite with state-of-the-art avionics, communications systems, computer networks, and sensors.

Benefiting Canadian industry


Extensive industry engagement was carried out to advertise the requirements and to ensure potential solutions were available prior to the release of the AIMP request for proposal, whenever competition was a possibility.

Industry was notified through an advance contract award notice that the original equipment manufacturer was being selected to conduct the work for ASLEP due to intellectual Property rights.

The Industrial and Regional Benefits (IRB) Policy was applied to the AIMP block III, imaging radar system (IRS), ASLEP, system support avionics and airframe maintenance projects. The Industrial and Technological Benefits (ITB) policy was applied to block IV.

As of May 2019, total IRB/ITB obligations are as follows:

  • AIMP block III: the full $359 million have been completed
  • Imaging radar system: $356 million of $374 million have been completed, with $18 million to be identified
  • ASLEP: $240 million of $266 million have been completed, with $26 million in progress
  • System support avionics: the full $271 million have been completed
  • Airframe maintenance: the full $534 million have been completed
  • Block IV: $240 million of $285 million have been completed, with $45M to be identified

Project cost

Project cost

The total approved cost in 2019 for AIMP and ASLEP combined is $1.983 billion.



The project management office continues to work with General Dynamics Mission Systems – Canada and IMP Aerospace to more accurately define the cost and schedule for block IV production based on results of the prototype aircraft modification.

There is also a financial liability remaining for retroactive rate adjustments for block III production.
