Editorial Note: Between February and April 2018, The Central Blue and From Balloons to Drones, will be publishing a series of articles that examine the requirements of high-intensity warfare in the 21st Century. These articles provide the intellectual underpinnings to a seminar on high-intensity warfare being held on 22 March by the Williams Foundation in Canberra, Australia. In this article, Sean Carwardine describes the development of Royal Australian Air Force (RAAF) airfield defence policy and questions the adequacy of current policy in preparing the Air Force to defend its bases in a #highintensitywar situation.
Air power is generated from air bases. Therefore, in a high-intensity conflict, air forces should expect that their adversary will target their bases. Unfortunately, airfield protection in a high-intensity conventional conflict has attracted little attention in the development of the RAAF’s fifth-generation force. This article looks at the history of RAAF airfield defence, and in consideration of lessons learned, will propose critical questions for future tasking, capabilities, equipment, command and control, training, planning, scale, interoperability, and security force influence on the air domain.
Since 1929, the RAAF has had a single-service policy towards airfield defence, involving airmen providing low-level anti-aircraft and machine gun ground defence. Past RAAF airfield defence policy worked on the assumption of RAAF involvement in small localised, asymmetric or low-intensity warfare in a joint environment. The policy has developed in the context of operations involving rapidly deployed aircraft operating from forward bases secured by allied nations supplying the bulk of force protection. These bases have been in relatively secure rear-areas of sanctuary, with security focusing only on countering the threat of small incursions. In a modern high-intensity war situation, these sanctuaries may no longer provide a guarantee of safety or security. Accordingly, the RAAF and its airfield defence policy must evolve. RAAF airfield defence policy must consider force protection in a high-threat environment, and possibly without significant assistance from major allies.
The RAAF has never been in a position, apart from five months in the Second World War, to provide full airfield defence for its bases in a high-intensity war situation; it has been partly or wholly reliant on allied forces.
During the Second World War, RAAF policy focused on the Australian Army providing low to high-level anti-aircraft defence and ground defence outside the wire. Within the wartime RAAF, there was a clear divide between RAAF Headquarters (the RAAF’s administrative command) and RAAF Command (the RAAF’s operational command) as to the workforce and organisation of airfield defence in the RAAF. The former believed small sections of Guards (20-30) could protect RAAF assets with technical airmen acting in the role as a secondary duty (a reactive defence). For RAAF Headquarters there was no requirement for a specific organisation to provide airfield defence. RAAF Command was against this ‘penny pinching’ policy and promoted a ‘RAAF Regiment’ of guards so that specialists focused on protection, and technical airmen focused on keeping aircraft in the air.
By 1945, the RAAF had the equivalent of five squadrons worth of guards (1,042 guards) in No. 2 Airfield Defence Squadron of the First Tactical Air Force (First TAF), five squadrons worth in the Northern Command (723 guards), four squadrons worth in Security Guard Unit/No. 1 Airfield Defence Squadron (570 guards) in the North-Western Area Command. Approximately, 1,900 guards (some cross-trained as war dog handlers and guard gunners) were also allocated to every aerodrome, inland fuel storage, radar/radio station, wharf/dock, RAAF chemical warfare storage, bomb and ammunition storage, civilian aerodromes and squadron in southern Australia. In addition to the guards, the Service Police had small units in every capital and small numbers on stations and in some squadrons. These forces provided the full scope of air base defence requirements for the RAAF.
At the end of the Second World War, the Chief of the Air Staff (CAS) removed airfield defence from the RAAF, six months before the official disbandment dates. RAAF Service Police strength was also reduced to fewer than 100 airmen across the nation. CAS stated, ‘I am not prepared to agree to any more of these specialised units.’ However, senior airmen argued against this. In 1945/46 senior officers such as Air Commodore Frank Bladin (Deputy Chief of the Air Staff), Air Commodore Frederick Scherger (Commander of First TAF), Air Vice-Marshal William Bostock (Air Officer Commanding RAAF Command) and Air Commodore John McCauley supported a proposal for a new airfield defence policy and the formation of an RAAF Regiment as put forward by Wing Commander George Mocatta.
Mocatta was Operation Staff Officer – Defence for the RAAF Command Headquarters Allied Air Force, a post which he held since 1942. He was a graduate of the Royal Air Force’s (RAF) Defence Officer course, and in 1944/45 Mocatta had studied the ground defence of airfields by the RAF Regiment in Europe and the Far East.
Mocatta’s proposal argued that the formation of a RAAF Regiment would see a reduction to around 2,000 guards and 300 police but would provide a full-time airfield defence force that included a ground fighting force, low level anti-aircraft force, airfield engineers, explosive ordnance disposal, mortars and armoured vehicles. Mocatta’s proposal was not progressed; it stayed in RAAF Headquarters un-actioned until the file was closed in 1949.
During the 1950’s, under the National Service Scheme, two aerodrome defence squadrons were formed to train reserve airmen as Ground Gunners. Early in the 1950’s a total of four Aerodrome Defence Officers, 25 Guards and a small number of Service Police were sent to Japan and Korea to provide squadron guard duty and security. Although low-level ground base air defence was considered a RAAF responsibility, the RAAF provided no ground-based air defence of any type on operations in Korea.
Between 1952 and 1955, the Air Staff Policy Memorandum No. 15 RAAF Ground Defence Policy (ASPM 15) highlighted the possibility of a conflict on a global scale against Communist forces. This possibility of high-intensity war would force the RAAF to establish its light anti-aircraft (LAA) defence units, thus releasing the Australian Army from this duty. The policy also raised the possibility of an attack by Communist ground forces, in either large-scale commando style or clandestine attacks. Under ASPM 15 active and passive defence of RAAF assets would be undertaken by six Rifle Squadrons, one Armoured Squadron and three LAA Squadrons of Guards or Ground Gunner reservists.
The 1950s saw another push for the formation of a single permanent Airfield Defence Squadron. The idea this time was similar to Mocatta’s 1945 proposal; however, this time the proposal focused on a single peacetime squadron as a nucleus for a war-time RAAF Regiment. Then in the late 1950’s, the RAAF Ground Defence Policy Chapter of Air Staff Doctrine listed no requirement for ground defence units and highlighted only the need for a few Ground Defence Officer’s, Aerodrome Defence Instructor’s and Guards, with National Service airmen training as Ground Gunners in the reserve.
By 1957, the policy of RAAF airfield defence changed in response to the evolving strategic situation. No major global war was foreseen. Therefore, there was no need for RAAF ground defence forces. The policy was that under an inter-service agreement, the Australian Army would provide all active and passive defence for RAAF assets. The only time the RAAF would require its active defence was when units were overseas, operationally deployed away from land forces or in an emergency. Also, RAAF commanders would initiate their ground defence force from airmen within their unit.
In the early 1960’s the RAAF trained Aircraft Hand/General Duty airmen and RAAF Service Police in infantry tactics to perform airfield defence for duty in Thailand. By 1965 the RAAF created a new mustering for airfield defence and guard duty; the Airfield Defence Guards (ADGs) were formed. Again, the idea of a RAAF Defence Squadron equipped with low-level air defence capability emerged, resulting in the acquisition of eight 40mm Bofors Anti-Aircraft Guns and 140 Oerlikon 20mm cannons for the proposed formation of a peace-time airfield defence squadron. Interestingly, in the files, a staff officer queried this policy asking, ‘who are we going to shoot them at?’ The Bofors ultimately went to the Australian Army, and the Oerlikons stayed in storage. The RAAF then introduced the Bloodhound missile defence program, by 1968 the system was outdated, and the project ended.
Throughout the 1960’s and 1970’s, RAAF policy on ground defence focused on limited war. Unsurprisingly, the ground defence policy for Vietnam focused on low-intensity warfare with an allocation of a 30-man flight of ADGs. At the time, RAAF Ground Defence policy (AAP 938) highlighted the RAAF’s responsibility to provide its own ground-based air defence units using equipment such as 20mm cannons and surface-to-air missile systems. One paragraph in AAP 938 indicates the RAAF did not have any of these systems and would have to acquire them from Britain, ‘when the war starts’. This raises the concern that in a high-intensity conflict, waiting for equipment would be too late. By 1973, the RAAF officially removed anti-aircraft defence from RAAF capabilities, instead relying on the Australian Army’s ground-based air defence (GBAD) systems or aircraft to provide air defence.
The 1980’s and 1990’s saw separate Rifle Flights of ADGs around the country, undertaking guard duty and exercises. During this period, however, the reformation of No. 2 Airfield Defence Squadron and eventually combined all Rifle Flights into one squadron in one location. Operation Warden, the Australian-led intervention in East Timor, in 1999 highlighted the capabilities and the benefits of having a dedicated, air-minded, air force security force in a low-intensity environment. However, having one full time and one partly-staffed reserve unit (No. 1 Airfield Defence Squadron), demonstrated the need for a force protection restructure.
In the subsequent shift to the asymmetric conflicts of Iraq and Afghanistan, RAAF security forces have integrated with Australian Army units and law enforcement agencies to protect aircraft in Aircraft Security Operations, protect air force detachments and take responsibility for the defence of international airfield defence duties. This is the basis of airfield defence policy that still defines RAAF Security Force approach.
Group Captain Jeremy Parkinson, an RAF officer from NATO’s Joint Air Power Competence Centre stated ‘Firstly, because of a lack of understanding of how [Force Protection] is provided, it is all too often seen in capitals and headquarters as little more than a static guarding task and as such is not perceived as contributing to the actual delivery of the mission’. He also stated, commanders, have a lack of understanding of how complex and resource intensive force protection is, and one should not assume that ‘the host nation will provide’ airfield protection for deployed forces. Considering Parkinson’s statement, it is fair to ask: does the current RAAF Security Force structure cater for all air base defence requirements, does it have an absolute, definite intent of potential operational tasking?
In a high-intensity conflict in the future, it is likely the Australian Army would deploy a brigade, which would likely include GBAD for the field force. The RAAF would deploy an Air Task Group to operate from a coalition airfield. What is unclear is if deploying as part of a coalition force, and with US or NATO units in place, would Australia be required to supply a Security Force Squadron? Would Australian GBAD systems automatically attach to the forward air base as stated in the 2016 White Paper? What capability does a current RAAF Security Force bring to the table?
I believe that the RAAF has been guilty of turning a ‘Nelsonian blind eye’ to the need for its own air base defence capability. History shows the RAAF has a lack of understanding of the specialist nature of all air base protection as it has developed a reliance on others, an aversion to committing fully to the airfield defence role and does not appropriately resource airfield defence. Are we learning from history, or following it?
Some questions need to be asked if the RAAF is to prepare to defend its operating bases in a high-intensity conflict. Does the RAAF insist Australian Army GBAD systems be permanently on every air base or will they be allocated to the RAAF after the start of combat operations? Does the RAAF have dispersed hardened or underground shelters, its own air-minded specialist protection force, or does current policy remain extant and we will rely on allies or host nations for our protection?
Analysts will discuss the pros and cons of the Australian Defence Force being a versatile and flexible force that can fight in low and high-intensity conflicts. However, the current legacy RAAF Security Force Squadrons remain established as a ‘small-war’ force, ill-equipped and lacking ground intelligence capabilities to protect air bases, overseas and at home, in a future high-intensity war?
Australia needs a RAAF specialist security protection force that is equipped and trained to respond across the spectrum of future conflict scenarios. A fifth-generation air force must be able to defend the bases that generate its air power.
