\"\"For the past few years, Andrew Davies has examined the annual USAF budget projections for the F-35A Joint Strike Fighter (most recently<\/span> here<\/span><\/a>). The F-35A will be the most numerous of the three variants of the joint strike fighter, and it\u2019s the model Australia has<\/span> committed to acquiring<\/span><\/a>. The projected cost and production numbers of the A model have<\/span> continued to stabilise<\/span><\/a> since the 2012 program re-baselining, and we decided to see if the other two variants exhibited similar trends. The answer is yes, but the journey has been an interesting one.<\/span><\/p>\n

The F-35B is the USMC variant, equipped with a vertical lift engine to allow deployment from amphibious ships. Italy and the UK are currently the only two foreign buyers of the F-35B, and USMC<\/span> declared initial operating capability<\/span><\/a> (IOC) last year. The F-35C has larger, foldable wings and is equipped for the stress of arrested landings on carriers. The USN is its only customer and is aiming for IOC<\/span> in 2018<\/span><\/a>.<\/span><\/p>\n

The data on both those more specialised variants indicates a more turbulent history than that of the A model\u2014shedding some light on the pitfalls of<\/span> joint-service platform development<\/span><\/a>\u2014but has stabilised in recent years.<\/span><\/p>\n

The three variants were originally intended to have<\/span> 70-80% hardware commonality<\/span><\/a>, and the USN budgets even costed the F-35B and C as a single line item until FY2010. Engineering and design changes through the life of the program have instead resulted in three essentially distinct aircraft, with only about<\/span> 20-25% commonality<\/span><\/a>. \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0<\/span>
\n\"im<\/span><\/p>\n

Note: The change in gradient of the calculated learning curve reflects the very small production numbers early on<\/span><\/em><\/p>\n

Likely as a result of the increasing difference, the F-35B was given its own<\/span> separate budget line<\/span><\/a> [pdf] in FY2011. In 2012, the program was<\/span> re-baselined<\/span><\/a> and production significantly deferred. The impact of these changes can be seen in the fluctuating cost estimates across this time period, possibly also reflecting attempts to spread program costs across multiple years. (See Figure 1)\u00a0\"\"<\/span><\/p>\n

The biggest success story from this data analysis is that the F-35B moved from such uncertain circumstances in the FY2013 budget to IOC in July 2015 (a little more than three years later). And the 2017 budget sees production accelerate for the first time since the program began, with eight aircraft being brought forward, bringing the cumulative total to 168 aircraft by FY2021. \u00a0(See Figure 2).<\/span><\/p>\n

\"\"<\/figure>\n

Note: No forward projections for F-35C from FY2009 or FY2010<\/span><\/em><\/p>\n

The cost projections for the F-35C are less volatile than the B model, which is encouraging given the still-low production numbers (See Figure 3). Production of the C model started in 2010, two years after the F-35B, and has remained slow, at four-to-seven units per year. Production delays in FY2013 and FY2015 (see Figure 4) also indicated possible reductions in the total number of aircraft to be acquired over the life of the program. But the total of 340 units seems to have survived, albeit now spread over a longer acquisition time frame.<\/span><\/p>\n

\"\"<\/figure>\n

Delays in the delivery of the F-35C have been<\/span> accompanied by purchases<\/span><\/a> of an increased number of F\/A-18E\/F Super Hornets and EA-18G Growlers (an electronic warfare variant of the Super Hornet). Over the FY2008 to FY2017 USN budgets, projected total Super Hornet acquisitions increased from 494 to 584, and Growlers from 80 to 160. This is probably not solely due to delays in the F-35C, but reflects a need to replace ageing \u2018classic\u2019 Hornets and the EA-6B Prowler, which the Growler replaces. And we shouldn\u2019t ignore Congress\u2019 penchant for adding Super Hornets to the budget,<\/span> regardless of whether<\/span><\/a> the USN even wanted them.<\/span><\/p>\n

Like the B variant, the FY2017 budget sees accelerated production of the F-35C. There’s still some volatility in the flyaway unit cost through FY2019, but overall the C variant cost also appears to be stabilising. This would suggest that confidence in hardware development has firmed, allowing the programming of higher rates of production.<\/span><\/p>\n

The data shows that production costs are stabilising across all three variants, and are projected to be consistent with industry standard learning curves as the production rates increase. This is good news for the program, and is<\/span> consistent<\/span><\/a> with<\/span> recent<\/span><\/a> commentary<\/span><\/a>.<\/span><\/p>\n

However the program’s not entirely out of the woods. There are lingering problems with the<\/span> on-board software<\/span><\/a>\u2014as well as the computerised<\/span> logistics system<\/span><\/a>\u2014though the USAF is still planning to declare IOC<\/span> before the end of 2016<\/span><\/a>. There’s also a plan for a nearly<\/span> US$3 billion program<\/span><\/a> to further upgrade the F-35\u2019s capabilities in the near future, known as Block 4.<\/span><\/p>\n

Overall, the more recent figures reflect increasing stability in the F-35 program as a whole. But the earlier data is a journey through the ‘joys’ of joint development programs. The evident uncertainty should provide ample context for USAF F-35 program chief Lt. Gen Bogdan\u2019s recent advice to \u2018<\/span>think really hard\u2019<\/span><\/a> before deciding on any future joint-service platforms. <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
