Background   —   Special Ops Vehicle Candidate   —   Supacat Jackal

Jackal Origins – the Supacat HMT 400 Truck
The  Supacat  HMT 400  is a  high mobility light tactical vehicle for  the British Army  and  Rapid Reaction Force. The powerplant is a mid-engine Cummins BTA 5.9 turbo-diesel  in common with several other British Army vehicle types.[1] The 'cab' is a light, removable structure attached  to a tubular  roll-over cage. With modification, the HMT 400 formed  the basis for the  SOV Jackal.

A Supacat for Special Ops  –  High Mobility Truck to a  Jackal  Mobility Weapons Mounted Installation Kit
The HMT 400 chassis was designed for rough terrain driving – with such features as adjustable ride height [2] and a belly pan. SOV modifications primarily involved  redesigning the roll cage to form the main gun ring (what the British Army calls a WMIK or Weapons Mounted Installation Kit). The passenger seat has a swing-out  gun mount  for the crew commander. Another gun position (on a swing-out mount) has been shown set up on the rear cargo deck. [3] A Jackal could easily accommodate a crew of four (as demanded by the SOIQ) and three gun positions but with reduced payload  (which is larger than requested anyway).

For the cargo/litter carrier role, weather protection comes in the form of  a soft- top (right). The gun ring and  rear deck of  the  fighting vehicle can be covered with a fitted tarp (below, right). The flat deck  HMT 400 progenitors can have a small  box  shelter  mounted on the bed. As a result, converting the Jackal into an ambulance (or a better protected cargo/litter carrier) will be comparatively easy.

In its size, armament, and carrying capacity,  the Jackal will get  full marks.  Where it is weaker in meeting  Canadian requirements is commonality with existing CF vehicles.  None of the Jackal's main components – main gun mount, chassis or engine – are in use by the CF. If  DND places as much value on parts commonality as their SOIQ suggests,  the Jackal must claim a transmission in common with the RG-31 APV  (Allison S2000) and LAV III tires (335/80R20 XML). Not much to go on. Supacat [4]  must  push performance.

[1] This includes the Truck Cargo 4 Tonne GS, a Leyland DAF 4x4 and, as a re-engining program, the CVR(T) family of armoured vehicles.
[2] For the CF SOV, a ground clearance of  260mm is mandated. The Jackal has a clearance of 280mm (on roads) which can be adjusted to 380mm for off-road driving.  Maximum clearance (front) is 530mm. 'Kneeling' with all air removed from the tires, clearance drops to 180mm.
[3] The widely-distributed image of a Jackal armed with GPMG, AGL and rear-mounted M2 appears to be a speculative photo-retouching.
[4] Supacat is a very small firm and has had trouble meeting orders  (and the British MoD placed further orders in June 2008 after success- fully deploying the Jackal to Helmand  Province in April).  DML in Plymouth has been organizing Jackal production for the British Army. Lockheed Martin bought the HMT 400 series rights and  North American distribution rights, so DND may be dealing with LM for its SOV.
