Bidders for the Canadian Forces Close Combat Vehicle (CCV) are

required to provide what is being Risk Reduction Unit (RRU)

vehicle. Essentially, that will be a vehicle that the Defence

Department can blow up in testing. The testing is tentatively scheduled for spring 2010.

Here is the answer the government provided to industry officials when they asked- “Can you further describe the Risk Reduction  Unit (RRU) vehicle?”


ANSWER: The qualifying bidders from the SOIQ participating in the RFP will be requested to provide a RRU vehicle for Underbelly Blast and Fragmentation Improvised Explosive Device (IED) destructive testing. The RRU vehicle should include the following:



• Hull (must structurally match the proposed CCV)

• Full belly armour kit

• Drive train parts such as wheels, differential, suspension and other components

• Suspension should be adjusted to respect the nominal ground clearance at combat weight

• Sufficient parts to stabilize the wheels and to allow the vehicle to be towed for a few hundred meters

• Seats, seat restraints and foot rests (all except turret seats)

• Underbelly armour and/or spall liner

• Proper surrogates are acceptable for any larger equipment that can interfere with seats and crew (such as a battery box)


Not Required:

• Engine, transmission, transfer case

• Turret

• Add-on armor kit and spall liner on upper walls and roof

• Instruments and electronics

• Stowage


Other Considerations:


• If the above Not Required items are not included, enough ballast should be installed to bring the vehicle to nominal combat weight; the vehicle Centre of Gravity position should be respected as much as feasible


• Test equipment (such as cameras, lights, sensors) will be installed on the hull by DND. Some welding and/or drilling and tapping may be required. Visual markers may be glued or painted to the hull, floor or seats for movement tracking purpose


• Following the test, a complete visual inspection of the RRU vehicle will be performed. All visible damage will be measured, photographed and documented. Part of the protection kit may have to be disassembled to allow for this inspection


• RRU should be clear of hazardous fluid (environment) except those required for the suspension parts (fluid type and quantity must be documented)
