Blastmaster.
I was involved with a couple of aspects of the original IM/FV requirement including the other contenders.
Bug is actually correct. Like it or lump it, it's a Timoney that was bastardised to the IM/FV specs.
What you won't see in the internet histories is the fact that the project was almost canned in 2001 - it only got legs because the govt of the day needed to secure Bendigo, and there were a lot of Govt votes to be had in that locale.
What you also won't find is that there were a number of reviewers who preferred one of the other contenders and the feeling was that local jobs at election time polluted the integrity of the decision.
Personally, I agree with quite a few of my cohorts that we picked the wrong vehicle.
Bastardized Timoney? Much of the original design work was actually done in Adelaide by a small team which included two really switched on Perry engineers with drawings going back and forth between Adelaide and Ireland for checking and conversion into electronic drawings as the data pack was gradually built up whilst the prototype was being built. I am also aware that there was also design assistance from S&S with one of their engineers assisting with the design work particularly relating to the powerplant/transmission installation.
Fact of the matter is that very, very few if any drawings from the original Perry prototype were carried over into the new ADI re-designed Bushmaster. Bastardized design? You cannot be serious.
As I recall there were two other contenders left by the time ADI got involved with the Bushmaster project - The Taipan and the BAe contender, Foxhound and the Foxhound dropped out soon after.
The Taipan was "leading contender" at the time and the original development Taipan with the standard manual Unimog transmission did a trip around Australia visiting a number of Army bases as a bit of advance marketing and promotion.
When the Taipan had to be converted to automatic transmission, the picture changed dramatically and it became a race against time to re-design the Taipan and qualify it again with its new Renk auto transmission and as I recall it not only did it not make the February 23, 1998 delivery deadline, but suffered numerous transmission failures and problems to the point where at one stage during the trials, the South Africans flew in a complete repair team to come and re-work these machines to keep them going at Bandianna.
About the Foxhound I cannot comment as it never made it to the official trials, so which other vehicles you think were better would be interesting to find out as there were only 3 at the end.
Sure, the Bushmaster was not faultless, but it certainly gave a better account of itself overall in the trials.
And yes, what you say about the Bushmaster almost being canned is certainly correct (read the ANAO reports on the Busmaster contract on the net) and whilst I may go along with some of the reasons you put forward why the project was "not canned", I may not completely agree with you that these were the only reasons for not cancelling it - there was definitely a lot more to this story.
As I said previously, there is much, much more to the Bushmaster story.
