Part 1: here
So, having looked at the personnel carriers, we get to the weapons platform variants (watch the designations; ‘CC’ here denotes a Conventional [non-articulated] Vehicle with main armament and ‘AC’ denotes an Articulated Vehicle with main armament). Some of the images are scattered in the paper, so I have cobbled them back together.
Cobra AC-1 – 3 crewmembers, armed with 4 recoilless 105mm rifles with 180 degrees of traverse
Cobra AC-2 – 3 crewmembers, armed with 4 recoilless 105mm rifles with 180 degrees of traverse
Cobra AC-3 – 3 crewmembers, armed with 3 recoilless 105mm rifles with 60 degrees of traverse, 18 rounds
Cobra CC-1 – 2 crewmembers, armed with 4 recoilless 105mm rifles with 180 degrees of traverse, 12-14 rounds
Cobra CC-2 – 3 crewmembers, armed with 2 or 4 recoilless 105mm rifles with 180 degrees of traverse, 20 rounds and one .50cal MG
Tracked Jeep – 2 crewmembers, 8mm of armor, one 105mm rifle (60 degree traverse, 6-8 rounds) and a 60hp engine
Modified Universal Carrier – 3 crewmembers, 19mm of frontal armor, two 105mm rifles (180 degree traverse, 19-20 rounds) and a 60hp engine
We’ve seen the ‘family’ of Cobra vehicles, the armoured personnel carriers and the existing Canadian designs for a Modified Universal Carrier and Tracked Jeep, which, compared to it, are inferior in terms of mobility and firepower, but you may recall I mentioned earlier another Canadian project called ‘Groundhog’. Other platforms are part of these early cross-country mobility trials as well, included the ‘Goliath’ and the ‘Laurentian Beetle’. This is a sadly scarce summary of the entirety of what is known about them (apologies in advance but the image quality is very low).
Groundhog – tested at Maupusesing, Ontario during Winter 1949-1950, it resembles a flat bed cargo carrier tracked vehicle and was envisaged at some point to have a rigid body for it.
Goliath – cca 1949
Laurentian Beetle – prior to 1950/1, an improvised conversion of a commercial tractor which is artificially high due to the lack of relocation of the transmission.
Unidentified project from 1950/1951
Part 3 will conclude this project with discussions over the armament and World of Tanks
