Why the UK needs the Joint Strike Fighter

01 June 2010

Andrew Brookes, Director of the Air League, explains why he believes the costly Joint Strike Fighter, the F-35 Lightning II, is worth every penny


The F-35 Joint Strike Fighter (JSF) is a fifth generation, supersonic warplane combining advanced stealth with fighter speed and agility, plus fully-fused sensor and network-enabled capabilities. It is being manufactured in three versions with major degrees of commonality (100 per cent when it comes to the avionics). There is the Conventional Take-off and Landing (CTOL) F-35A, the Short Take-Off and Landing (STOVL) F-35B and the F-35C aircraft carrier variant (CV). The F-35A aims to meet or exceed the performance of the F-16 while offering greater range, stealth, enhanced lethality and lower operating/support costs. The F-35C is strengthened for US Navy carrier operations. Standard internal payload for CTOL and CV versions is two AMRAAM air-to-air missiles and two 2,000lb precision air-to-surface weapons.

In-between comes the STOVL F-35B. The F-35B poses the greatest technological challenge in that it needs a powerful new 41,000lb thrust engine that could both hover and transition smoothly to supersonic performance. 'Bring back to the deck' capability dictated a reduction in the size of the weapons bay, so the F-35B's Initial Operational Requirement (IOR) is two 1,000lb precision weapons to be carried internally. In 2002, the British MoD announced the STOVL variant as its preferred choice, though that decision has yet to be confirmed formally. The UK is paying $3.8bn towards the development of JSF, which includes a $2bn contribution to the F-35 systems development and demonstration (SDD) phase. The latter will provide UK specific development activity, such as British weapons integration, integration of the aircraft on the Queen Elizabeth class carriers and other UK unique requirements, such as a tailored airworthiness and safety case. In a ceremony on 7 July 2006 at Fort Worth, the F-35 made its public debut and was named Lightning II. The Pentagon plans to procure 2,483 F-35 Lightning IIs, while the UK intends to buy up to 150 for the RN and RAF.

On 26 January 2010, Sqn Ldr Steve Long became the first British active-duty service pilot to take to the skies in an F-35 Lightning II. He brought the second F-35B to a landing at the US Navy's Patuxent River test and evaluation airfield in Maryland. "What this aircraft really gives the Royal Air Force and the Royal Navy," said Long, "is a quantum leap in airborne capability because of the sensor suite it carries. An F-35 pilot will have an unprecedented level of situational awareness about what's going on in the airspace around him or her, and also on the battlefield or ocean below. Not only that, but the F-35 will plug into coalition battlefield networks and be able to pass that picture on to all other players in the network."

With the capability to operate from a variety of ships or austere runways, the F-35B can deploy closer to shore or nearer to front lines, reducing distance and time to the target, and thereby the need for support assets such as airborne tankers. The British F-35 effort is coordinated by the UK Joint Combat Aircraft Project Team, with the UK now preparing RAF and RN pilots and engineers for initial training at Eglin AFB in Florida. The Brits will begin operating their aircraft in 2011 alongside their colleagues in the US Marine Corps (USMC).

As the most powerful single-engine fighter ever made, it has been assessed that the F-35 will be four times more effective than legacy fighters in air-to-air engagements, eight times more effective in prosecuting missions against fixed and mobile targets, and three times more effective in new age Intelligence Surveillance Reconnaissance (ISR) and Suppression of Enemy Air Defences and Destruction of Enemy Air Defences (SEAD/DEAD) missions. It will require a significantly smaller basing footprint.

But all this costs serious money. At the 2005 Paris Air Show, the average flyaway cost of an F-35 was put at $40-60m, with the F-35A CTOL at the lower end and STOVL/CV towards the higher. 'Affordability' is crucial and even in the US, rising war costs and the stubborn budget deficit forced the Pentagon to cut the combined USN/USMC buy from 1,089 to 680. The F-35 development programme has been delayed by 13 months and 122 aircraft were clipped from near-term production profile to pay for cost overruns. The STOVL test at Patuxent River came only weeks after US Secretary of Defense Robert Gates penalised Lockheed Martin with a $614m award fee withhold. The flyaway cost of an F-35 today is estimated at around $112m.

Even before exchange rates are taken into account, this is too high a price for some. In early March, Lord Guthrie, who was CDS at the time of the 1998 SDR, said that: "We need to trim the equipment we think it would be 'nice to have', and think in terms of what we 'must have'." He went on to say that the UK should invest in a larger overall fleet of smaller vessels, instead of buying the multi-billion pound Queen Elizabeth class aircraft carriers and accompanying Joint Strike Fighters.

Would this be wise? The Chief of Air Staff, ACM Sir Stephen Dalton, is aiming for just two fast jet types in his RAF fleet by 2020 to reduce the logistic tail. Typhoon is already procured, which leaves space for one other type. No worthwhile alternative to JSF will come cheap. Boeing's new F-15 Silent Eagle, which combines traditional F-15 capabilities with a reduced radar cross-section and internal weapons bay, could cost $100m per aircraft. To satisfy the cost cutters, the choice for the UK is not between JSF and something comparable at half the price but between having a meaningful fast jet to serve alongside Typhoon or nothing at all.

If the UK is to remain a major league player, it needs the F-35. The $300bn F-35 JSF programme is potentially the largest weapons procurement programme in history. There are currently 115 US-UK defence information exchange agreements, with a further 20 in the pipeline. The fighter will increase interoperability among allied air forces and create new training and maintenance requirements that will foster stronger military-to-military and industry ties. F-35 production techniques will revolutionise stealth aircraft manufacturing. If the UK opts out of the JSF programme, there is a serious risk that the UK's position in world aerospace, as well as the transatlantic defence technology relationship, could go with it.

Critics often overlook the fact that the F-35 is an awesome intelligence gathering tool underpinned by around 20 million lines of software code. This software controls the fire control and weapon systems, as well as the radar and sensors, but most importantly, the code allows all the systems to recognise each other and work together. Block 0.1 software (about two million lines of code) created the fire control and aircraft management systems needed for the first F-35 flight from Fort Worth. The Block 0.5 software upgrade equipped the STOVL JSF with the code for electronic warfare and radar systems. This will be followed by Block 1.0, which will provide an integrated capability so that the location and nature of targets can be shown on a single display screen. Engineers will also start integrating various sensors into the aircraft in Block 1.0. Blocks 2 and 3 will add software functions that allow the aircraft to monitor itself for maintenance work and allow for the integration of more sensor and weapon capabilities. The USMC is confident that the F-35B will be ready for an initial operational capability (IOC) in 2012 with Block 2B software, which will allow the use of two AIM-120D air-to-air missiles and two 1,000lb Joint Direct Attack Munitions or two 500lb laser-guided bombs – all carried internally to stay stealthy. With this software, the aircraft will be able to fly at 7g with a 50 degree angle of attack. The first USMC unit is not slated to deploy until 2012 and the UK could receive its F-35Bs thereafter. The USAF and USN have slipped their IOC until 2016. The F-35 production rate is expected to reach its peak at one aircraft a day in 2015 (about 250 aircraft a year): this is a far more dynamic rate than that of Lockheed Martin's stealthy F-22 Raptor, which is currently produced at a rate of 20 a year.

The F-35 is undoubtedly having development problems, but this is not surprising given that the technology is F-22 plus 15 years. The F-35 may be a single-seat fighter but it is not designed for a single-seat war. The Lockheed Martin chief test pilot has pronounced the F-35 as very easy to fly because in-between the pressures of take-off and landing, the pilot is given time to think about what he or she brings to the battle.

The F-35's sensor suite is the most powerful and comprehensive of any fighter in history, and will combine with an unprecedented networking capability to give unparalleled situational awareness. The jewel in the crown of the F-35 JSF is the Electro-Optical Sensor System (EOSS), which consists of a Distributed Aperture System (DAS) to provide 360-degree situational awareness, and the Electro-Optical Targeting System (EOTS). The DAS is so potent that it enables a pilot to see through the aircraft floor. There are over 120 entries in Specification which enable JSF to datalink, communicate and interact with other warfighters. The F-35 will display information rather than data and bring unprecedented capabilities to the US and its allies. This in turn means that the RAF and RN will need to train people to deal with a broad strategic picture, rather than their bit of sky. With a JSF wing-man 20 miles away, close formation tactics will no longer apply. Rather than just flyers, F-35 pilots will be masters of the battlespace and go places they have not been to before. The F-35 battlespace manager will identify threats and provide answers via data fusion from others' off-board sensors right down to individual soldiers on the ground. Flying the F-35 will demand a whole new mindset.

So if the UK wants to be able to operate alongside the US on day one of any future conflict, it needs JSF. The F-35 will enable the UK to seize the initiative in the development of future concepts of operations for air-to-air and air-to-ground missions in hostile airspace. But it is not only the UK armed services that will benefit from the JSF programme. Unlike previous collaborative fast jet acquisitions that have been based on industrial workshare, JSF is hailed as a programme where 'best value' drives industrial content. Given its long involvement in STOVL technology, UK industry has won roughly 15 per cent of the JSF production programme, meaning that by value, each JSF that takes to the skies has 15 per cent UK content. With a projected global fleet in excess of 3,000 aircraft (which could make up 85 per cent of the world's tactical fighter fleet by 2030), UK industry stands to gain an estimated £30bn worth of business on JSF. The UK needs to remain a prime partner in the biggest acquisition programme in Pentagon history.

But some savings will have to be made. I foresee the UK carrier order scaled back from two to one, even though that would only save £300m once penalty clauses are taken into account. The initial STOVL F-35B order will probably be cut to around
65 to enable British forces to conduct expeditionary operations around the globe. Thereafter, the UK should order a second tranche of larger, longer-ranging F-35Cs for delivery around 2020 to replace Tornado GR4 in the long range strike role.

After considerable expenditure, the F-35 programme is picking up momentum. The UK should keep its nerve because the JSF Lightning II is going to be a winner, both for the military and industry. The UK has engaged in four inter-state conflicts over the past three decades and when the next one pitches up, the counter-insurgency kit procured under UOR for Afghanistan may have very limited utility. When that day arrives, the UK will need JSF.

First foreign release of the F-35 is set for 2014. The RN should get its first squadron of 10 F-35Bs then, not wait til 2018. That cuts the aircover gap by 4 years, allows experience to be gained before the bulk turn up & makes the UK look serious about the project. Cutting the second carrier now would be typical folly. All the R&D costs on just one hull!
The new carriers should gain an angled deck & arrester gear to create a hybrid like the Russian carrier.This would allow both F-35B & C to be operated by the RN. The F-35B for all weather cover, the F-35C for long range heavy strike. Perhaps 60 F-35B & 35 F-35C.
I cannot see why the RAF should get the F-35. The Typhoon serves the fighter/short range strike role. The Tornado GR4 needs to be replaced by a longer range aircraft. The ideal aircraft would be a modern cross between the Vulcan & the F-111. The proposed 2018 bomber (more likely 2022 the slow way its going) would be ideal. The UK should ask for 10% like the F-35.

It does seem a great aircraft, albeit a very expensive one. It is just a shame that we didn't retain the capability to build complete new fighter aircraft ourselves. Throwing our lot into multi-national collaborative programs was one of the worst post war defence decisions we as a country have made. Constantly held hostage to fortune and political developments in member countries. Typhoon is a brilliant example of how not to do it. A very good aircraft, but a decade late and massively over budget. It will be virtually obsolete by the time the last aircraft enter service.

Given that Financial Services have proved to be more of a curse than a blessing, the only thing going to get UK plc out of the mire is more in-house high and medium tech manufacturing - which of course covers defence/military products as well as spacecraft/satellites. We need to concentrate again on rebuilding our industrial capacity to provide primarily for our own needs on a self sufficient basis. Exports should be seen as a nice bonus, but not integral to a projects success. For this reason i hope that JSF is the last of our collaborative ventures.

A first class article and argument on our future needs.
So far as single service needs are concerned it would be sheer folly to cancel the Prince of Wales for a saving of 300 million; not much in the greater scheme of things. Particularly after so much money has already been spent. Don't forget these carriers are not just Naval toys they are planned as tri-service assets. Give, enough, and all, F35's to the RN for two carriers. We really do need to look at and adapt the USN/USAF Air Sea battle concept to our own perceived needs too. i.e. being pushed further offshore .... an emerging nation equipped with advanced Russian fighters and Air Defence systems comes to mind; as does the new containerised Russian cruise missile which they will obviously export. Does anyone remember the Falklands Exocets mounted on a trailer? The RAF should stick to Typhoons, MPA and ISTAR and, perhaps the RAF/AAC, Bronco COIN type aircraft that could, with the Apaches, fly off the new carriers when needed.
Much talk is going on about jointery; but that indicates a need for two carriers to support our future light/medium? equipped Army.
In short: we need the right mix of joint forces that are equipped for rapid/quick reaction and still able to punch well above their weight. The Carriers and F35 must be the backbone of this as the list of countries that will give us access to bases is getting shorter.

If this article is to be believed, it means that only the JSF can go to war alongside the US. If this is the case then does it mean that the Typhoon will be sidelined in any future conflicts involving the US and UK working together?

Bizarre extravagant irresponsible nonsense. Huge amounts of money per plane, plus expensive support and thru-life costs no doubt, for a vehicle which can only carry only 2 1000 lb munitions?
Someone has either lost their value-for-money marbles here, or Boeing has run away with the cheque-book!

Two 1000 lb bombs . . gee, that's good value for tens of millions of pounds per aircraft isnt it (NOT)?

the aircraft is yet to enter service for training to comence a point it should have reached by 2008 with IOC orgianly due in 2011 for the F-35A 201 and is now officially only $25m ish away from the F-22's flyaway price of $150m or £103.5m per aircraft. And of course we all know what the US government did to that aircraft order. The current estimate as of the 1st of June puts the F-35C at around $191.9m or £130m for an aircraft that's yet to land on a carrier. And if that price is to remain the same our current order for 60 would cost £7.8b do we really need to spend anymore on this aircraft?

As for the UK money already invested in the F-35 either way you look at this project it relies on one thing, and that one thing is out of the UK's governments and other partner nation's control. With a US order or without the US order to have a plane for the rest of other partner nations it relies on US staying in this project and to keep the price down for the rest of us they also need to be ordering lots of them 2,500 plus this would bring the fly away cost down to around $90m or about £61m. If however the US for what ever reason decided to pull out there will be no aircraft for any of the partner nations to buy anyway. From what I have found out because we entered the project at Level 1, even if the UK pull's out now and the US and the other countries went ahead with there order's we would still get a healthy return on the £3b we have invested in the project so far. We would also generate a healthy profit from any further orders from other customers down the road. On the other hand there is also a real possibility that come 2016 we will have a nice new aircraft

This is quite correct. The comments made by Lord Guthrie are to be expected from a convential "brown" General. The army still do not understand air power, buzzing helicopters like the AH64 will not survive in a scenario when we may have to fight an enemy who has an air force and knows how to use it. We not only need Typhoon and Lightining, we also need a decent long range strike aircraft like the Tornado

The JSF spells the end of the indigenous UK aircraft industry. The UK makes the best combat aircraft in the world, the US marketing machine then pushes an inferior alternative and prevents the UK developing a world beating fighter design for the strike roll. JSF vs. Typhoon, yes, but also the Phantom verses the BAC Lightning. History has shown that the BAC lightning was easily the best combat aircraft of its day and was never exported or developed as much as it could have been. Do we learn nothing?

And I fear we are going the same way with the Typhoon. You only have to look at the effect of cancelling the Typhoon tranche 3B. With 2000+ BAE staff loosing their jobs and probably 10 times that in the wider industrial sector in the UK. Where as cancelling the JSF for the UK armed forces would have a negligible effect on the UK aerospace industry. Where is the long-term benefit of the Navy buying the Phantom in the 70's, so why should there be any from buying the JSF now.

No, cancel the JSF, which is really only a replacement for the Sepecat Jaguar (same range, payload & speed), navalise the Typhoon and fly it from both carriers. Develop indigenously the Taranis or something very like it (only bigger) to use as a strategic bomber to launch from the carriers. Cancel Trident, preferably for an indigenous resurrection of the Black Arrow rocket. Remove most of the RAF's strike assets and give them to the Navy. Remove the army from Germany and only have an army big enough to launch from Navy ships.

Basically have a defence and foreign policy closer to that of France where British interests come first and we maintain as independent a stance as we can. Fire or retire as many of the transatlantic freeloaders in the MOD who have allowed the UK armed forces to become a slightly less trigger-happy division of the US Marine Corps.

Commenting on R.E. Hex - UK Retired RAF point that the Tornado is a decent long range bomber.

Utter nonsense, the Tornado is a short range strike aircraft with a combat radius of 300 miles with a meaningful payload. This is because the Tornado was built to German requirements in the cold war. Actually the Tornado has a range/payload capacity similar to the Typhoon, only the typhoon is obviously more manoeuvrable and quicker accelerating.

The last decent long range bomber the RAF had was the Buccaneer, which with an avionics upgrade and some FADEC for the engines would give the RAF what this gentlemen was referring to. As an option that is too British and would give the RAF an asset the US could not match. So the transatlantics would see to it that this option would never see the light of day.

Fifth Generation? probably. Supersonic? definitely. Advanced Stealth? Only in the sense that the RAM requires less maintainence and is less vulnerable to damage by rain and sunlight than that used in earlier stealth aircraft like the F117 and B2. The F35 is much stealthy than than these aircraft, or the F22 Raptor. Compared with the F22, it is also inferior in every other significant repect in terms of performance and capability. Comparing the two aircraft, it could be said that whereas the F22 was designed to be the best fighter in the world, the F35 is more a product of what might be termed the Henry Ford philosophy.
Fundamentally it is a compromise between several things; a fighter, a strike aircraft, a VTOL aircraft, and something that the US Navy can use for air show displays- a "fighter plane" in the traditional sense of the word, with "fighter speed and agility" as Brookes puts it. That is at least two compromises too many.
The F35 is not stealthy enough to survive in the face of modern air defence systems, and it does not have anything like the range it would need to have to meet certain future contingencies, even when deployed on a carrier.
J. Southworth - University of Hull

05 October 2010

Possibly the most significant compromise in the F35 design is that between "fighter speed and agility" as Brookes puts it, and range/payload. Granted, the F35 does not have quite the dynamic performance of some previous aircraft, but even so it seems clear that the US Navy in particular put combat radius a long way down in the list of priorities after speed, acceleration and high g manoeuvering capability. They might claim that this was done partly for safety reasons- they used to write hundreds of aircraft each year in the days when jet engines were less powerful and responsive than they are now. But in any case, the requirements for a high thrust/weight ratio and supersonic speed is bound to cripple range/payload performance.
I can't help getting the feeling that the F35 was really designed more for air show displays than anything else. Surely it is too expensive to be put in situations (eg, close air support) where people might actually shoot at it? Bird strikes would be embarrassing as well.
When it comes down to it, the F35 is a product of the idea that it is possible to take a conventional jet fighter aircraft and turn it into something more sophisticated by ajusting a few details and adding some radar absorbent material, rather like adding options to a car. I think this is what they mean by advanced stealth, that you don't have to think about it any more. In reality, of course, it doesn't work like that at all. The basic configuration of the aircraft has to be optimised if the aim is to produce a truly stealthy aircraft like the BAE Taranis UCAV or the B2. Sorry for any spelling errors in my previous posting.

The right choice for Britain was three new build slightly enlarged Invincible class concept carriers flying the STOVL JSF. It may be that so much money has been spent already on the Queen Elizabeth class, that it would be very expensive to scrap the project, so perhaps the best solution is one QE class flying the STOVL JSF and an aim to supplement it with a new build Invincible class concept light fleet carrier when economic conditions would improve.

McDonald Douglas tried selling me the F-18 in 1993. We didn't have any carriers that could fly it and BA systems was touting 6 Tornado replacements which were financially viable to them but couldn't reach any of the operational scenarios being analysed at that time. F-18 would provide most of the flexibility that we currently don't have in terms of range and interoperability with the US (and Canada) at a fraction of the cost of the F-35. It is madness to have carriers with no aircraft as it was madness to waste billions on going for the STOVL F-35 variant. Typhoon was a disaster via concept, operational analysis and capability - no scientific need and analysis, fraudulent COEIA studies and an IAB incapable of understanding technical issues and the financial implications to UK defence capability which are now coming home to roost.

Excellent, we should have this machine, and it should have followed on directly from the Harrier. The problem is that the Army has forgotten that air power is needed for air superiority, over land and sea and if you remember the Falklands without the SHAR and the RAF GR reinforcements we could have been humiliated by a third or fourth rate power. Former CDS Guthrie does not seem to realise that this is not "nice to have". If we have to go to fight a war against a nation who has an air force and is prepared to use it and knows how to use it, then it becomes a must have, the army and the surface forces of the navy would not be able to operate, no good relying on Apache helicopters, this is an expensive nice to have and without air superiority they would be useless. Drones would also be useless for the same reason. Not everything is going to be counter insurgency in the future. The F35, like the Harrier, is fully deployable to anything at sea and on the land and does not need massive runways. I am afraid the army is responsible for agitating to cut the air force and the navy, and they really should be ashamed of themselves.

Having an interest in aircraft for many years but only as a layman I believe the JSF dev is absolutely necessary to replace the Harrier. The Harrier proved the principle but is now unforunately outdated and slow. Its days as the prima donna of the Falklands campaign are well over. It is hoped that the new aircraft can be developed at a sensible cost and will answer the majority of our wish list.

Given the number of criticisms of the F 35 on technical grounds, it seems almost gratuitous to point out that it looks a bit like....a duck. It's the combination of the rather bulky fuselage and the chiselled nose contours. That might not be so bad if it did'nt fly like one as well. If the viability of the aircraft in the strike role is doubtful, it's a complete joke as a ground attack/close support aircraft. The F 4 Phantom was considered too big and heavy for close support, this aircraft weighs at least as much and only has one engine. The experience from Afghanistan with the Tornado and the Harrier again demonstrates the need for something smaller and lighter.
A Small-ish UCAV with a payload of about 500 kg might well be ideal as it would, if properly designed, be able to operate from unpaved airstrips in the forward area. No need for air-conditioned clubhouses and miles of concrete runway.

"Not all future wars are going to be about counter-insurgency". Really? I'd be interested to hear a single scenario in which the UK alone is fighting a country that "has a decent air force and is prepared to use it."

How many countries can anyone think of that have a better fighter aircraft than Typhoon, that have the organisation and logistics to support it, and that we might be fighting? Fighting alone, that is.

And if we were fighting alone, why would we need interoperability with the F35s of the US?

One more thing - hand on heart: if fighting, say, Russian aircraft of the 1980s or older, or even the latest F16s owned by some newly-rogue Middle Easter power. Even fighting other Typhoons owned by the same: would the F35 really be more able to assert air superiority than the Typhoon variants either in service, on order, or recently cancelled?

I think it's perfectly fair to say that politicians and others (me included) are ignorant of technical issues. But it's also true that defence manufacturers and boys who want new toys, are often equally ignorant - perhaps deliberately - of the realistic threats and the needs to meet them.
