Procurement and development
The programme favours maintainable British, American, European and New Zealand equipment. Heavy armour serves selected formations; light infantry, engineers, signals, artillery and logistics carry much of the island-support role. An amphibious formation includes boats and ship-compatible equipment, but a tracked vehicle’s limited swimming ability is not an open-ocean transport system.
Model register
| Period | Model or equipment family | Formation and purpose | National adaptation |
|---|---|---|---|
| 1945–1950s | Lee–Enfield No. 4 / SMLE, Bren and Owen | Infantry and reserve transition | Local ammunition, depot repair and tropical maintenance; veterans build a common training standard |
| 1945–1950s | Matilda II, M3/M5 Stuart and wartime carriers | Limited armour, reconnaissance and engineering inheritance | Refurbishment, radios, recovery and training; obsolete armour leaves frontline use as new tanks arrive |
| 1945–1960s | 25-pounder and Australian short 25-pounder | Field and pack-artillery transition | Local ammunition and repair; lighter guns support difficult terrain while heavy equipment remains transport-dependent |
| 1950s–1970s | Centurion Mk 3/5 lineage | 1st Armoured Regiment and selected defensive armour | Australian/NZ crew and depot network; tropical reliability, communications and later sight/fire-control work; heavy armour requires appropriate naval lift |
| Late 1950s–1980s | L1A1 SLR, MAG 58/M60 and later F1 | NATO-calibre infantry and supporting machine-gun families | Licensed/local production where selected, common ammunition and national armourer training; F1 is a later 1960s family |
| 1950s–1960s | Ferret scout car; Saladin reconnaissance option | Reconnaissance and territorial security | Shared radios, dust protection and easy field support; Saladin is an evaluated fire-support option rather than a universal tank replacement |
| 1960s–1980s | M113A1 and national command, mortar, ambulance and recovery variants | Mechanised infantry, engineers and amphibious support | Local vehicle support, communications, protected specialist variants and corrosion control; limited water crossings require approved preparation and conditions |
| 1960s–1970s | M2/M101 105 mm and OTO Melara Model 56 pack howitzer | Field and air-portable mountain/island artillery | Common fire-control procedures, radio links, locally supported ammunition and helicopter/landing-craft logistics |
| 1960s–1980s | Carl Gustaf, 81 mm mortars and period anti-armour weapons | Infantry fire support and reserve issue | Licensed ammunition/sights and instructor cadres; later guided weapons enter only after their acquisition and training |
| 1960s–1970s | UH-1H utility helicopter; later CH-47C | Army lift, evacuation and engineering support | National radios and tropical sustainment; Navy supplies ship aviation coordination and Air Force retains orbital/rocket command |
| 1970s evaluation | M60A1 and Leopard 1A3 | Centurion replacement competition | Compare maintainability, weight, sights and national sustainment; select the Leopard-derived AS1 route for standard issue |
| Late 1970s–1980s | Leopard AS1 / Leopard 1A3 basis | Professional armoured core and recovery units | Domestic maintenance, communications and sights; later thermal/fire-control improvements are separate 1980s refit work |
| 1970s–1980s | Scorpion CVR(T) and M113 reconnaissance variants | Light reconnaissance and New Zealand regional formations | Low transport burden, radio/sight upgrades and common mechanical support; distinct from main battle tanks |
| Late 1970s–1980s | British L118/L119 light-gun family | Air-mobile and amphibious artillery | Select ammunition-compatible variants; local fire-control, meteorological and survey support; deployment remains limited by lift |
| 1980s | M198 155 mm towed howitzer | Selected heavy field-artillery units | National ammunition support, prime movers, communications and artillery training; heavy gun batteries are not issued to every island garrison |
| 1960s–1980s | Bofors guns; later Redeye/Rapier and RBS 70 options | Airfield, port and deployed air-defence regiments | Period-correct acquisition batches, identification and radar/communications integration; distinct short-range systems use their own training and supply chains |
| Late 1980s | F88 Austeyr and Minimi/F89 family | Professional infantry followed by trained reserves | Domestic production, armourer training and common 5.56 mm ammunition; distribution follows trials and unit conversion |
| 1950s–1980s | Land Rover, Unimog, recovery vehicles and engineer plant | Transport, engineers, medical and repair corps | Local bodies/workshops, tropical filtration, standard radios and modular stores; trucks and maintenance capacity underpin readiness |
| 1960s–1980s | Assault boats, landing craft and tracked/logistics support | 2 RAR and the 2nd Australian Amphibious Division | Navy-compatible lift, buoyancy/safety and loading standards; signals, medics, engineers and artillery form complete task units |
| 1945–1980s | Valve, transistor and later digital field-radio/survey systems | Signals, intelligence and electronic-warfare corps | Australian electronics and New Zealand precision/simulation work progress by decade; secure networks and direction-finding develop alongside operator education |
Production and refit blocks
| Block window | Combat equipment | Support and communications | Force-development emphasis |
|---|---|---|---|
| 1945–1949 | Wartime infantry arms, limited tanks and 25-pounders | Repair workshops, field hospitals, port and road engineers | Restore order, demobilise/reorganise and retain professional technical cadres |
| 1950–1954 | Centurion acquisition; improved conventional infantry/artillery support | Common radios, vehicle depots and rehabilitation medicine | Korean experience strengthens casualty care, training and sustainment |
| 1955–1959 | NATO-calibre small-arms transition and lighter artillery | Amphibious transport, engineer and signals standards | 2nd Australian Amphibious Division established in 1956 around 2 RAR |
| 1960–1964 | M113, reconnaissance and pack/field-gun introduction | Transistor communications and common vehicle/weapon maintenance | Island-support formations integrate logistics, medical and language-trained personnel |
| 1965–1969 | M113 specialist variants and mature infantry support | Helicopter lift, field networks and protected engineer/medical capacity | Vietnam-era deployment lessons shape tropical reliability and veteran care |
| 1970–1974 | Leopard/M60 trials, Scorpion and light-gun planning | Digital survey/fire-control research, better transports and workshops | Professional armour remains concentrated; lighter formations suit island lift |
| 1975–1979 | Leopard-derived standard; new light-gun and anti-armour batches | CH-47 support, common depots and regional engineer/medical cadres | PNG statehood regularises the state command in 1975 |
| 1980–1984 | M198 batteries, later short-range air defence and improved sights | Digital communications and mobile repair/medical support | Fiji statehood in 1980; maritime-security and territorial reserves expand |
| 1985–1989 | F88/Minimi conversion and selected thermal/vehicle upgrades | National EW processors, simulators and sustainment software | Refit professional cadres first, then train and equip ready reserve units |
Commonwealth land blocks
Army blocks are procurement and refit packages, not a claim that every battalion changes weapons on the same date. Trials precede professional-unit conversion; reserve training, ammunition and maintenance follow. A brigade with new vehicles but insufficient mechanics or radios has not completed the block. Coastal artillery and later maritime missiles receive their own control, training and certification rather than being treated as ordinary infantry weapons.
Australian and New Zealand contribution
Australia provides licensed small arms, ammunition, vehicle overhaul, engineering plant and electronics. New Zealand expands precision manufacture, sights, simulation, medical logistics and mountain/cold-weather training. Local Papuan, Timorese and Pacific units receive common national standards alongside language training and community liaison. Their modernisation funds schools, technical colleges, health services and maintenance trades as part of the wider public-development policy.
Regiments, reserves and naval lift
1 RAR keeps its conventional infantry role. 2 RAR and the amphibious division combine infantry, engineers, reconnaissance, artillery, signals, transport and medical detachments with Navy lift. The 1st Armoured Regiment supplies the armoured core. State and territorial regiments retain local recruiting traditions and the common national service system. These model choices leave the established decade-by-decade personnel series unchanged; trained, equipped readiness is tracked separately from nominal reserve strength.
