Background  —  Armoured Patrol Vehicle Candidates  —  Bushmaster

ADI’s Bushmaster [1]  was the outcome of Australia’s ‘Project Bushranger’ to develop a mine-resistant  light APC. [2]  The hull form  follows that of  South Africa’s Casspir (a V-shaped welded-steel monocoque) but the Bushmaster’s design was begun by Ireland’s Timoney. In ADF parlance, a Bushmaster is an ‘Infantry Mobility Vehicle’ – others would say the small end of APCs. As such, Bushmasters are rather large for patrol duty. But, flexibility is built in: ADI is offering an array of ‘Bushie’ variants including command, mortar, ambulance, and several other planned support vehicles. [1]

In fine Aussie tradition, ADI also developed a Bushmaster ‘ute’ – the ACSV or armoured combat support vehicle, a crew-protected convoy vehicle with a flat bed (10m2) grafted on. No requirement for such a CF vehicle exists yet but this may be of  future interest.

The Bushmaster hull will withstand blast from two TM-57 anti-tank mines (equiva- lent to 19kg of TNT) and has been tested extensively. ADI was slow getting Bush- master production underway, but  now it seems to have found  its stride.  Even so, the entry of Bushmaster into the contest for a CF APV (backed by Thales Canada) appears to have surprised DND planners but, a greater size aside, the ‘Bushie’ did fit the APV requirement.

Despite its virtues and  flexibility, Thales Canada reportedly  pulled the Bushmaster IMV from the CF APV contest at  the last  moment. Size was likely  the  key objection. The ADF chose its Bushmaster to fit between jeeps and the ASLAV (the Aussie Coyote or Bison). CF APVs fill a different slot but there may be room, in the future, for a CF Bushmaster-sized mine-protected vehicle. [3]

[1]  In 2006, Australian Defence Industries became Thales Australia  ( Thales group having previously owned a 50 per cent share in ADI ).
[2] These include logistics, combat engineer, mineclearing, and weapons carrier variants  (the last 3 types based on the ‘flat-deck’ ACSV). Under their LAND 116 program, the ADF have ordered another 143 improved Bushmaster IMVs to be delivered by 2008. The ADF Bushie was deployed to Iraq and Afghanistan in 2005. Dutch army Bushmasters (an IOR purchase) have been in Afghanistan since October 2006.
[3] It has been suggested elsewhere that the Bushmaster would make a good mine-protected gun tractor  to replace withdrawn CF AVGPs.
