Moving 1 Bde to Darwin was pretty clueless, the fact 1 Armd was reorged into a composite reg/RRes/ARes unit at the same time was just stupid. How on earth was a territory with a smaller population that many a capitol city suburb meant to man a reserve sqn of MBTs? Had some discussions with a recruiting officer while visiting relies in Darwin Christmas 98 about transferring to C Sqn 1 Armd as an M-113 crewman, the idea they were pushing was I would go full time reserve do the Leopard courses and then slip across into A Sqn and the regs, just goes to show how desperate they were to get people after the move north.
APIN (Army Presence In the North – the official name) was and is a disaster for the Army. Apart from the huge cost of building Robertson Barracks that would have provided many more facilities in the south east it has seen a significant retention loss and training loss. You can’t train a mechanised force during the middle of a monsoon season territory wide flooding that happens every summer. Army knew it was a disaster and tried very hard to avoid it but it was a politically motivated decision and they had to suffer it.
As a pure hypothetical I wonder if the armouring of the CMF CAV would have been more affordable and sustainable if the chosen mount was an evolved Sentinal.
Well the decision not to order the AC3 Thunderbolt (Sentinel was only the name for the AC1) into production resulted in a significant problem during WWII for the Army’s armoured force. The no go on production of the AC3 was because the Government thought it would be easier to get Churchills or Shermans. However in reality none were available until 50 odd Churchills arrived in late 45. In the mean time the Matilda and Grant tank force was crippled by a lack of spares which had significant effects on the Matilda’s use in theatre.
So in ‘what if’ world if the 200 strong AC3 order had gone ahead the Army would have had a serviceable tank with Australian sourced spares for use in 44-45. A tank which BTW would have much better combat power than the Matilda via the 25 Pounder (88mm) gun in place of the 2 Pounder (40mm) gun.
What would have this meant after WWII? If the AC program was kept in the works then 200 AC3s and 400 AC4s (AC3 with 17 Pounder/76mm gun and later new air cooled engines) were to be ordered. Assuming all or most were built during the war then the Army would have an excellent tank park for post war use. Spares would be available in Australia from the subcontractors and the engines used anyway were common mass production car (Cadillac V8s) or light airplane (Gyspy Major) engines.
It is more than possible that a post war AC5 could have been ordered in 1950-52 if the industry capability was still in place rather than Centurion tanks. Which is likely considering the hull and turret armour castings were outsourced to private industry that still exsists today. During WWII the AC was trialled with torsion bar suspension. Such a hull armed with a 20 pounder and the quad air cooled Gypsy Major engine would be lighter, faster, easier to maintain and much longer ranged than the Centurion with just as much armour and firepower. Without the high cost of the Merlin engine, rolled steel plates, welding work and import costs it would probably be much cheaper.
So yeah I reckon 1 and 2 Armd Bdes would be in a much better position come 1956 for long term retention with a fleet of Australian built and sustained AC3/4/5s rather than clapped out Grants and to expensive too buy Centurions.
