Background  —  Cougar and Buffalo  Mine- / Blast-Resistant Vehicles

“... You’re supposed to be the hard case!” –  Two New Blast-Resistant Vehicles for the CF
Force Protection Industries of South Carolina announced the sale of 10 of its vehicles to the Canadian Forces on 04 May 2007. The order – placed on behalf of Canada by the US Navy [1] – is for five each of the mine-/blast protected Cougar and Buffalo engineering vehicles. A third vehicle type on order is six  South African  Husky mine detectors. Cougars are 6x6s. Early reports of a reduced window area suggested a British Mastiff variant[2] but this was not the case. The three CF types – Cougar, Buffalo and Husky – will form a new Canadian Forces Expedient Route-Opening Capability (EROC).

  Force Protection  Cougar  Route-Prover  —  Specifications
  Powerplant:   7.2 liter, 243 kW, 6-cyl. Caterpillar C7 diesel
  Transmission:   Allison HD-4560 P  five-speed  automatic
  Size:   length x 7.08 m, width x 2.74 m, height x 2.64 m
  Weight:   13.61 t, max (curb) 13,635 kg, GVW 15,900 kg
  Payload:   maximum payload up to 1,820 kg  (4,000 lbs)
  Crew:   2  (driver, vehicle commander )  +  8  troops
  Range:   Operational range 965 km  (600 miles)
  Performance:   road speed: 105 km/h (65 mph), ford: 1m (39")

Like the CF  RG-31 Nyala Armoured Patrol Vehicle, the Force Protection vehicles used ‘V’-shaped monocoque armour hulls to protect them from blast effects ( left ).  As with the APVs, the Cougar and Buffalo designs originate in South Africa. A major difference is in powertrain – the Force Protection types using drivetrains adapted from US commercial  trucks. Cougars have crew side doors (right) plus a conventional rear door [3]  which allows egress  from the compartment by the 8-person EOD (Explosive Ordnance Disposal ) team.

The Buffalo  is a specialized mine clearer /anti-IED vehicle using its distinctive robot arm to  probe an object identified by the Husky  – disposal is done by an EOD team from  a  Cougar.

  Force Protection  Buffalo  Mine Resistant Vehicle  —   Specs
  Powerplant:
 
  12 L, 330 kW, 6-cyl. Mack  ASET (Application
  Specific Engine Technology) AI-400 diesel
  Trans.:   Allison HD-4560 P  five-speed  automatic
  Dimensions:   length x  8.2 m, width x  2.46 m, height x  2.97 m
  Weight:   20.56 t, max (curb) 20,600 kg, GVW 38,180 kg
  Payload:   maximum payload up to 1,7580 kg  (38,680 lbs)
  Crew:   2 (driver, vehicle commander ) + 12  EOD squad
  Range:   615 km  (382 miles) with 320 L (85 gal) fuel tank
  Performance:   road speed: 105 km/h (65 mph), ford: 1m (40")

Both Force Protection types are components of the US Army Interim Vehicle-Mounted Mine Detector system (along with a relative of the Husky). This US system has now been modified  to allow the detector vehicle to be remotely- controlled from the Buffalo. When a suspicious object  is found, that extensible, 30' (9.15m) arm is used to investigate from within the relative safety of the hull. US Army Buffalo have been mine/IED clearing in Afghanistan since first deploying there in July 2003.  This is a big improvement for the CF engineering reconnaissance.

[1] The US $8.867M contract ( $9.77M Canadian) was placed by the US Navy on behalf of the Canadian Expeditionary Force Command (or CEFCOM). The Navy is involved because the US Marines’ Systems Command will administer this contract under a Foreign Military Sales agreement covering supply (through May 2008), spares, field service, and  training.  As 07 May 2007,  no FMS notice had been published.
[2] British Army Mastiff  PPV (Protected Patrol Vehicles) are similar to the US service as the JERRV (Joint EOD Rapid Response Vehicle) as bought by Canada. However, Mastiffs had extra armour protection (initially spaced armour plates, but deployed Mastiffs have slat armour.
[3] The larger Buffalo has only the rear door but its crew remains inside the vehicle during most operations.  The Cougar’s side doors are desirable (especially if the crew have to bail out) but the openings for doors make it more difficult to form a completely rigid hull structure. The hulls of both Cougar and Buffalo are mine-resistant, their armour (and ballistic glass) protected against IEDs and 7.62x51 mm rifle fire.
