1939 Sep: WW2—Mobilising for War: RAAF at the Outbreak of WW2
𝐎𝐯𝐞𝐫𝐯𝐢𝐞𝐰
Australia declared war on Germany on 3 September 1939 and rapidly mobilised the RAAF, activating expansion plans, calling up reservists, and reallocating scarce aircraft to maritime patrols and home defence. Cabinet directed immediate cooperation with the Navy, prioritised sea-lane security, and accelerated production policy, while negotiations with Britain shaped expeditionary commitments and the Empire Air Training Scheme framework emerging by year’s end.
𝐆𝐥𝐨𝐬𝐬𝐚𝐫𝐲 𝐨𝐟 𝐓𝐞𝐫𝐦𝐬
𝟏. General mobilisation: Government orders activating personnel, units, resources, and industrial priorities nationwide.
𝟐. Citizen Air Force (CAF): Part-time RAAF squadrons mobilised to reinforce regular operational strength.
𝟑. Maritime reconnaissance: Long-range patrols safeguarding shipping, convoys, and coastal approaches against threats.
𝟒. War Cabinet: Senior ministerial body directing strategy, priorities, manpower, and interservice coordination nationally.
𝟓. Aircraft allocation plan: Wartime scheme distributing scarce types to roles, theatres, and training pipelines.
𝟔. Base units: Administrative and logistical formations sustaining flying squadrons’ operations, movement, and maintenance.
𝟕. Industrial mobilisation: Rapid redirection of factories, labour, and materials towards aviation and defence outputs.
𝟖. Operational readiness: Measure of unit capability, including crews, aircraft serviceability, fuel, munitions, and command.
𝟗. Air–sea cooperation: Coordinated RAAF–RAN operations protecting sea lanes, convoys, and port approaches domestically.
𝟏𝟎. Expeditionary detachment: Deployed RAAF elements serving overseas under RAF operational command structures.
𝐊𝐞𝐲 𝐏𝐨𝐢𝐧𝐭𝘴
𝟏. Declaration and directives: War Cabinet orders on 3 September activated general mobilisation, prioritised maritime reconnaissance, and began redistributing limited aircraft towards coastal defence, with early decisions framed by pre-war Empire planning assumptions and immediate liaison with Britain to balance expeditionary ambitions against Australia’s pressing sea-lane protection requirements. Chapter 1 – The First Ten Months, RCDIG1070674
𝟐. Calling up the Citizen Air Force: Mobilisation recalled CAF personnel to regular duty, filled base units, and increased manning for reconnaissance flights while training establishments shifted to compressed wartime syllabi, tightening standards for pilots, observers, and wireless air gunners to generate rapid operational capability from a small peacetime cadre facing expanding commitments. Chapter 9 – Degrees of Readiness, RCDIG1070481
𝟑. No. 10 Squadron and expeditionary posture: The pre-war dispatch of No. 10 Squadron to Britain matured into immediate operational service in Coastal Command, symbolising Australia’s expeditionary contribution at war’s outbreak and demonstrating the tension between overseas reinforcement and home maritime defence obligations that shaped RAAF decisions through late 1939. Chapter 1 – The First Ten Months, RCDIG1070674
𝟒. Sea-lane protection first: With commerce and troop movements vulnerable, the RAAF concentrated available Ansons and Sunderlands on anti-submarine and convoy patrols, coordinating with the Navy and civil authorities to enforce surveillance over approaches, harbours, and shipping routes, a policy consciously prioritised before broader expansion delivered depth. Chapter 6 – Sea Lane Protection and Aircraft Production, RCDIG1070478
𝟓. Industrial decisions accelerate: Mobilisation spurred aircraft production plans, tooling, and contracts—guided by Cabinet—while procurement from Britain remained uncertain; the RAAF balanced near-term imports with domestic manufacture timelines, integrating maintenance capacity, spares pipelines, and workshops to sustain a rising patrol tempo. Chapter 6 – Sea Lane Protection and Aircraft Production, RCDIG1070478
𝟔. Empire doctrinal framing: Pre-war Imperial conferences and planning documents shaped Australia’s opening-war assumptions, aligning training, equipment policy, and command relationships with Britain, even as events forced local adaptations to geography, distances, and industrial realities during the first mobilisation months. Chapter 4 – The Empire Plan: Doctrines and Decisions, RCDIG1070477
𝟕. Training compressed and expanded: Schools shortened courses while increasing throughput, reallocating instructors and aircraft to meet wartime requirements; the force accepted risk in experience dilution, relying on strict procedural flying and rapid consolidation in units to achieve operational sufficiency under mobilisation pressures. Chapter 9 – Degrees of Readiness, RCDIG1070481
𝟖. Command arrangements adapt: The Air Board coordinated with Naval and Military staffs to allocate patrol sectors, refine signals procedures, and standardise reporting while preparing for anticipated reorganisation of higher command as wartime demands intensified beyond peacetime structures. Chapter 5 – The New Command, RCDIG1070724
𝟗. Balancing home and abroad: Early RAAF contributions to Britain created prestige and experience flows but competed with scarce aircraft and crews needed domestically; Cabinet maintained a cautious equilibrium while anticipating the Empire Air Training Scheme to supply future manpower at scale. Chapter 1 – The First Ten Months, RCDIG1070674
𝟏𝟎. Foundations for sustained war: By year’s end, policies for production, training expansion, and air–sea cooperation were embedded, giving effect to a mobilisation that, though constrained, created the organisational scaffolding for later operations across multiple theatres under increasingly demanding conditions.
