From "The Canadian Military Procurement System; A Study in Failure":
Unarmoured early testbeds from the Canadian Army's "Hailstorm" Armoured Vehicle Program
...Hastily designed (or should we say "designed") in 1974 and intended as a solution to all of the Trudeau government's armoured vehicle woes, the Hailstorm was intended to be an effective anti-infantry, anti-aircraft and anti-tank vehicle; with high mobility both on roads and cross country, a modular rear weapons station, and low operational costs, the Hailstorm Program was billed as the "weapons system of the future" in promotional literature produced by the Canadian Armaments Corporation (a special venture created specifically to coordinate the vehicle's development)...
...Causes for the vehicle's developmental failure were numerous, but largely stemmed from the rushed effort to set up the Corporation and get a paper design out the door in order to meet the opportunity that the company's founders had identified: with the Canadian Army's Centurion tanks in desperate need of replacement, PM Trudeau opposed to spending large amounts of money on military programs given his other priorities, and a small but influential group of military officers supporting the idea of a light, missile-carrying, wheeled vehicle rather than investing in tanks; which they viewed as obsolete- a view temporarily reinforced by the apparent victory of Soviet designed anti-tank missiles over Israeli tanks in the early stages of the Yom Kippur War...
...The company's founders, mysteriously well-connected in Canadian government circles, promised the government everything they wanted: an air-transportable, armoured, stealthy, and flexible missile carrier that would also be Canadian-built, cheap to purchase, and cheap to operate. CAC salesmen even proposed that the vehicle would serve as a good basis for a lengthened chassis capable of serving as an APC, and potentially in other roles. Prototypes were enthusiastically requested by the government, and development funding made available.
The chassis itself was a 6x6 trucks; the technology was scarcely cutting-edge and the appearance of rapid progress was easily achieved, with an unarmoured air defence version equipped with Quad-20mm cannon (though, in a sign of things to come, not the short-range anti-aircraft missile system) being swiftly constructed and demonstrated to a variety of enthusiastic officials. Army observers would start to note the problems even this early, however, with the integrated radar showing a variety of problems that were insistently blamed on user error by the CAC itself...
...Oerlikon Contraves was happy that their own effort to build a combined Anti-Armour/Anti-Aircraft missile system was now part of the government funded Hailstorm program. Although the possibilities of the ambitious missile system exited military planners, in practice reaching all of the goals set proved impossible before the difficulties of creating a new, Canadian, production line were added...
...The damage done to the Royal Canadian Armoured Corps by the Hailstorm, or more specifically to the delays to the replacement of its vehicle fleet due to the long drawn out period when the government, and sometimes the Army, believed that the Hailstorm would become a viable armoured vehicle, is extremely difficult to overstate...
(Images are from
here, a much earlier and less disastrous project than the Hailstorm. For the skeptical,
here's a reference that the Canadian government was looking into a notional, Canadian-built wheeled tank-replacement vehicle in the 1970s. I basically just added on the ADATS program and imagined the horrifying results.)
