Could an ANZAC solution be the way forward and how could it work?

Op Ed by Ueda Station

In Part One I proposed that a workable solution to revive a Kiwi Air Combat Capability was for New Zealand to acquire and then integrate an air combat component into the RAAF Air Combat Wing structure. I prefaced this by noting that New Zealand is likely to be seriously tested as grey zone threats (“The grey zone includes cyber attacks and disinformation campaigns and falls short of an actual shooting war”) and geo-strategic competition ramps up across all relevant domains – especially in the merged air-maritime context of the South Pacific and that a tactical air combat capability is becoming increasingly an imperative for New Zealand.

Of the current RAAF multi-role strike platforms, namely the F-35A, the EA-18G Growler, and the twin seat Boeing F/A-18F Super Hornet – it is my view that the logical solution is the Super Hornet. It has the best overall fit with what the RNZAF needs to generate an air combat component in terms of its affordability and our required employment contexts in the years ahead. Principally this is long-range maritime strike, tactical reconnaissance and airborne electronic warfare. Nevertheless as the Super Hornet is a multi-role combat aircraft it can be called upon to conduct a wide range of other missions as directed by the New Zealand Government. Since the Super Hornet uses the probe and drogue air to air refueling system it could quickly become interoperable with our new C-130J-30 Hercules. By retrofitting Cobham re-fuelling kits on the Hercules they can act as an air-tanker for a Kiwi Super Hornet mission package. That is something that its F-35A or F-16V brethren cannot do. Fitted with conformal and drop tanks, plus this air-tanker support, we would possess a strike platform that can then project out to a significant volume of airspace within our South Pacific and Southern Ocean areas of immediate strategic interest. All together as a package the Super Hornet is a very formidable multi-role force enabler and force projection capability – particularly within the cross-domain air-maritime context.

A Kiwi Super Hornet component that is integrated into the RAAF air combat fleet fleet solves the complexity and cost of trying to rebuild a tactical air combat capability from scratch. The synergies of learning and building up a new platform capability like the Super Hornet alongside a mature system operator like the RAAF, will greatly truncate the time, complexity and cost that the RNZAF will spend rebuilding the capability. It would be embedding into an established operational fleet, with existing training, support and sustainment structures in place and New Zealand would simply be paying our fair share of the bills to the contracted firms providing this – principally Boeing Australia, GE and Raytheon. New Zealand would also be expanding the operational synergies and strategic weight to the combined Anzac force structure and achieve economy of scale advantages to boot.

Though I do not have the latest annual cost of operations for RAAF 1 SQN’s Super Hornets the best projected estimate using Australian National Audit Office and Australian Budget figures are that the full extracted cost to operate their 24 F/A-18F capability is AU$245m per annum. A simple extrapolation of those figures means that if New Zealand were to contribute to the operation and sustainment of 12 additional aircraft to the existing 24 RAAF Super Hornet would it cost a further AU$122.5m p.a (NZ$135m) on top of this. Of that amount around $50 million would go towards the contracted support providers, the remainder is the cost of direct operational costs such as fuel, expended weapons, salaries, and administration.

However the clock is ticking if we want brand new Super Hornet aircraft. An incoming New Zealand government in 2023 would need to immediately start a dialogue with the Australian and United States governments to offer a proposal that focuses on the win-win aspect for all three nations in how a Kiwi component towards a joint RAAF-RNZAF Super Hornet squadron would work. It will have to move quickly to secure what might be the final production slots on the Super Hornet line at the Boeing St Louis plant. The US Navy wants to start redirecting money away from new-build Super Hornets and squirrel it towards its future NGAD (Next Generation Air Dominance) project as well as buy more carrier based F-35C’s. The House and Senate are not so convinced. A US$900 million budget extension in FY 2022 for the production of 12 new-build Super Hornets was a late inclusion in the revised 2022 National Defense Authorization Act unveiled by the House and Senate Armed Services committees on Dec. 7 last year following pressure from Mid-West based Senate and Congress members. But that was in extremis, and only for 12 further aircraft, to keep the St Louis production line busy through to Christmas 2024. Maybe another production block of 12 aircraft forced through in FY23 by House and Senate Armed Services committees could happen but that is as yet highly uncertain.

Like what happened with the final run of C-17’s these final 12 Super Hornets will possibly end up being “Whitetails”, meaning they are unlikely to be assigned USN serial numbers and will eventually become available on the open market as a commercial sale. So a narrow window of opportunity exists for New Zealand to take advantage of these final production aircraft – the worry would be if oil rich Kuwaiti grabs them first as they, along with the RAAF, are the only other operators of this aircraft type.

If the circumstances and timing were such that New Zealand could acquire these final dozen Super Hornets we should seize the opportunity. A Kiwi squadron of 10 operational aircraft and a training flight contribution of 2 aircraft embedded within the RAAF force structure would cost us US$900 million (NZD$1.33B). This is the “Gross Weapon System” (GWS) cost for the latest Block III Advanced Super Hornet variant, based on the US Department of Defence contract last December with Boeing for delivery in late 2024. Though the actual fly-away build cost of the Advanced Super Hornet is US$67.161 million per unit – the higher GWS cost is the true cost in that it allows for initial support, spares, training etc.

If new build Block III F/A-18F’s were not available there is the alternative option of acquiring used ex USN F/A-18E/F Block II Super Hornets that have all gone through the same spiral upgrades as the RAAF aircraft. To give you an idea of the cost of a used Super Hornet, the value of ex US military aircraft is based on a US Government Accounting Office calculation of current airframe hours deducted from the US Navy Specification SD-565-3-2 structural fatigue safe life standard, which in the case of the Super Hornet is 6000 flying hours. This is calculated by a percentage value that corresponds to the original GWS cost of the aircraft when delivered new to the US Navy. For example if the GWS cost was originally US$77.3 million per unit (the historical GWS average cost) and the aircraft in USN service had flown circa 4500 hours of its 6000 hour limit, then its present value would be 25% of its original GWS cost when new. In other words that Super Hornet would be now worth US$19.3 million dollars if sold to New Zealand as an US Excess Defence Article.

However, all these aircraft would require undergoing Boeing’s Super Hornet Service Life Modification (SLM) program. The first phase is an 18-month process of inspection, modification, repair and restoration that will extend the service life of the aircraft from its current 6000 flight hour (SD-565-3-2 limitation) to 7500 flight hours. During this phase, each Super Hornet is extensively disassembled, thoroughly inspected, and undergoes a restoration and repair process that takes 5000 man-hours at a cost of US$11.45 million per aircraft. At the end of this first phase the aircraft would be technically the same as the RAAF Block II but with an additional 2000 hours on their airframes. Nevertheless, an airframe that had 4500 hours prior to Phase 1 of the SLM would be able to fly for a further 15 years or around another 3000 flying hours in USN service flying off their Carriers. The reality though is that the refreshed Super Hornets would now be using military runways like RAAF Amberley and RNZAF Ohakea where the structural load stresses on the airframe are far less than the undulating short deck of a Carrier with catapults and arrestor gear. This alone can extend their structural fatigue safe life by a further 1000 flying hours (based on fatigue testing difference between carrier and non carrier airframes), which would give enough annual flying hours to see these ‘refreshed’ Super Hornets through to the late 2040’s.

For around NZD$46-50m per aircraft this “refreshed airframe” approach is a reasonable option. The only foreseeable issue is that the majority of them available would be the single seat F/A-18E model as they have numerically been the dominant variant of the USN Super Hornet fleet. This does have some repercussions in that the tactical reconnaissance role won’t have the same level of capability output or situational awareness due to the loss of the back seat role. It still can be done, but the pilot workload increases. If the decision is made to go down the cheaper “refreshed airframe” route it may be worth considering slightly increasing the number of airframes from 12 to 15, to allow for 12 single seat E models for operational tasking and 3 additional twin seat F models for training based at Amberley. These 15 airframes could be delivered in annual tranches of 3, starting with the 3 F models for training and the subsequent E models over the next four years. With the 2-year delay between ordering these “refreshed” aircraft and the Phase 1 upgrade process and delivery, prospective aircrew could start their training process. The expectation that 15 “refreshed” ex USN Block II Super Hornets would cost circa NZD$700-750 million to acquire. This compares to NZ$1.33 Billion for 12 new build Advanced Block III aircraft.

The future second phase of the SLM program, which can eventually run concurrently but over a further 12-month process, will see extensive additional modifications where the aircraft is effectively remanufactured to Advanced Super Hornet Block III standard like the most recent new-build aircraft now coming off the St Louis line. It is very likely that the RAAF Super Hornet and Growler fleet will be upgraded to Block III Advanced status within the next ten years. This Block III service life + upgrade which will roll out across the USN’s Block II fleet over the next 15 years adds another layer of utility and capability to the platform.

Some significant points stand out. Each airframe is essentially remanufactured to ensure a SD-565-3-2 airframe life of over 10,000 flying hours. Engine upgrades will see a 20% increase in thrust and fuel economy and combat range is extended by 20%. There is a 10% reduction in radar cross-section (RCS), and a further drop in RCS is achieved by use of ‘Have Glass IV’ like external stealth coating and a conformal fuel tank option is available increasing range even further. On the avionics side the mission computer, cockpit, and sensors have capabilities nearly on par with the F-35A. As yet there is no reported costing estimate available for the Block III upgrade as the Phase 2 SLM wont be given an allocated budget appropriation until FY24. Nevertheless consideration must be made for this future upgrade package, as it would seemingly be a wise synergetic circumstance in the context of the RAAF’s future F/A-18F and EA-18G developmental pathway.

But an air combat capability for New Zealand is not all about high level threats against the PLA(N) and PLA(AF) conducted under the umbrella of a joint Anzac air task force. Eventually, an Ohakea based squadron of 10-12 aircraft would also enable the RNZAF to conduct what is known as the Tactical Air Support for Joint Defence Operational Training role and thus provide the NZDF with greater integrated training across the land and maritime domains. These are tactical support and training roles that were a routine aspect of the former Air Combat Wing, which disappeared when the A-4K capability was disbanded.

Tactical Air Support (TAS) to Joint Defence Operational Training, are force enabler activities, which assist wider Defence Force elements in generating their readiness and training. TAS encompasses:

  • Air Defence training for RNZN and RAN Frigates,
  • Land-Air Integration Training for NZ Army Battalion Group Exercises,
  • JTAC/FAC training for 1 NZSAS and 1 RNZIR,
  • DACT for RAAF and other Pacific Forces,
  • OpFor(Air) for ADF/NZDF Exercises.

The TAS role is expanding now to include tactical support missions at the lower end of the threat spectrum such as Low Intensity Close Air Support for SASO (Stability and Support Operations) missions, Rapid Tactical Reconnaissance in HADR (Humanitarian Aid and Disaster Relief) situations, Maritime Enforcement Support in our Economic Exclusion Zone (EEZ – think the Kin Nan incident) and would give New Zealand a baseline domestic Air Security & Response capability for our AIDZ (Air Defense Identification Zone). Therefore just on these wider joint operational training and direct security benefits alone, bringing back a squadron sized tactical air combat component is not just a smart and prudent strategic hedge, but adds real depth to our wider force training competency and security posture. This is irrespective of it being primarily a deployable frontline kinetic combat asset within a Joint RNZAF-RAAF air strike package.

Building up to a 12-15 aircraft Kiwi air combat contribution would expand the joint RAAF-RNZAF Super Hornet fleet to 36-39 airframes, allowing for the eventual generation of two expeditionary squadrons each with 12 operationally tasked aircraft. The remaining element of 12-15 training aircraft based at RAAF Amberley would remain as the core pipeline for RNZAF and RAAF aircrew training as well as high level depot support and sustainment. If for any reason the Australian Government wanted to independently deploy its own “expeditionary” squadron and the New Zealand Government had reservations about such a move, the Australians are still free to do so within the context of their own existing airframe numbers. New Zealand would not detract from them being able to operationally uncouple and pursue its own defence needs. The core training structure would be intact. Likewise, if New Zealand noted a rise in direct grey zone security challenges, for example in the eastern South Pacific, to provide a presence and deterrence tasking, and Australia likewise did not feel it was in a position to commit its own assets towards this, New Zealand would still be in a position to do so with our own assets. Since both countries will always possess their claims of an independent foreign policy when push comes to shove, being integrated as per the above force structure does not restrict or force both countries to go against their independent stances on particular issues.

An incoming New Zealand government, as part of its air combat capability proposal to Australia, would also need to work with the RAAF in establishing a pipeline for Kiwi aircrew for Fast Jet Pilot (FJP), Air Warfare Officer (AWO) and ground technician courses – to prepare aircrew for that leap from our 14 SQN T-6C Texan II’s into the Super Hornet. The creation of a separate new LIFT (Lead In Fighter Trainer) capability like we had with the Aermacchi MB-339C is unnecessary and costly for the small size of our future air component. Obviously the New Zealand government would have to pay their way for each aircrew candidate seat on each FJP, AWO and Ground Support Technician courses. The competency of the RNZAF T-6C Texan is such that Phase 1 of the 14 week Introductory Fighter Course, can be carried out at Ohakea, before aircrew move to Phase 2 LIFT training on the BAE Hawk with RAAF 79 SQN at Pierce. Following Phase 2 of the LIFT course aircrew progress to a 20 week advanced air-to-air and air-to-ground weapons course with RAAF 76 SQN at Williamtown.

Fortunately there is some spare annual flying hours capacity within the RAAF Hawk fleet to train 2-3 Kiwi aircrew per annum, through both the Phase 2 LIFT course and advanced weapons courses as the RAAF are flying just 4050 annual flying hours on the Hawk fleet, which has the latent capacity to fly well over 6000 annual hours. Obviously, the New Zealand government will need to pay a pro-rata percentage of the AU$180m annual cost of the RAAF Hawk trainer capability for each candidate FJP and AWO. There are no current RAAF figures at hand regarding the cost per student pilot, however the closest comparison would be the Hawk T-2 at RAF Valley, which has a cost per student of £2.7m or NZ$5.2m through the Phase 2 LIFT and advanced weapons courses. The Canadian and RAF Phase 2 LIFT and Weapons courses possibly are alternate training options – if for any reason an RAAF course has a capacity issue.

Only once those two phases on the BAE Hawk are completed could Kiwi aircrew progress through to type conversion on the F/A-18F Super Hornet with 1 SQN’s training flight at RAAF Base Amberley. This eight-month long operational conversion course covers all facets of F/A-18F flight operations from the basics of flying the aircraft through to conducting complex tactical sorties including electronic warfare, tactical reconnaissance and maritime strike. From start to finish following around 3 years and 6 months of training on the Texan, Hawk and Super Hornet would the newly minted Kiwi aircrew will be considered operational.

There is also a way to truncate this length of time on the aircrew training front and kick-start a locally based capability faster. This can be achieved by the use of qualified FJP’s and AWO’s who are eligible for a lateral transfer into the RNZAF from Australia, Canada, United Kingdom and the United States of America. The NZDF already has a number of slots for personnel from our FVEY (Five Eyes) partner nations in highly specialist war-fighting roles who are eligible to serve as they either hold a Permanent Residence Visa with indefinite stay or following consideration from the Minister under s72 of the Immigration Act in light of their critical skills. This could be a way forward in that we would start with a mix of established experienced aircrew from our FVEY partner nations on short-service commissions, along with RNZAF graduate aircrew selected for the Super Hornet assignment. Of particular note this may be very useful with respect to getting hold of experienced Qualified Weapons Instructors, Qualified Flying Instructors and Qualified Air Warfare Instructors with Fast Air backgrounds.

When capacity is built up on the training and personnel side and sufficient New Zealand owned Super Hornets are in service, eventually we would begin to transfer operational aircraft and crew back home across the Tasman (leaving a permanent joint training attachment at RAAF Amberley for our ongoing training requirements). Working with Boeing Australia, who is the prime support and sustainability contractor to the RAAF fleet, a small Ohakea based operational maintenance and unscheduled repairable item replacement facility similar to what exists within RAAF 1 SQN would be required. This would include provision for hangar space, considerations for weapons storage, test and support equipment, administration, line maintenance facilities and potentially a flight simulator. A budget for this would have to be further investigated. However as an example of the size and scope of this facility, it possibly would be similar to RNZAF 3 SQN’s $43 million aircraft maintenance facility at Ohakea. Under this proposed integrated (though partially distributed) basing model our higher levels of depot level maintenance, engine sustainment, and general fleet support on the aircraft would still remain under the existing Boeing Australia, GE and Raytheon sustainment and support contracts that have already been in place for 12 years.

So there you have it folks, a pathway to a redux of the RNZAF air combat capability. One that can affordably provide New Zealand what it requires to cover our own direct air power needs, but also deliver a timely and appropriate force enabler to our closest and officially only defence ally – Australia. One that can get that 7th and vital Anzac expeditionary air combat squadron over the line in just about the time we and our other regional partners are going to need it. Without it the 2030’s could be very bleak.
