Examination of Witnesses (Questions 200-219)

MR JOHN HOWE CB OBE, MR VICTOR CHAVEZ, MR NICK MILLER AND MR CHRIS DAY

3 JUNE 2008

  Q200  Mr Crausby: Hermes 450 UAVs are currently operating in both Iraq and Afghanistan. Can you outline what capability they are delivering and what feedback you are receiving from our own Armed Forces?

  Mr Day: Today, if we look across both theatres (and I will speak generally about both theatres and specifics when we get to a particular point) we have now achieved somewhere in the region of about 9,000 operational hours, which is a significant total when we look at historic data. We support the MoD across a whole range of different types of operation. When we entered the journey, pretty much just over a year ago, the targets were tough and very difficult to meet; we had about six months to get this capability up and running, the regiment trained and ready to deploy; and more specifically, which has been one of the key areas that we have learnt probably most about, is the logistic support that we need in order to support our guys out in both theatres; and we have picked up an awful lot of information associated with that. We have to work closely with the guys because, at the end of the day, they are using it on average for about 14 hours a day—that is two air vehicles up each day for about 14 hours a day, every day of the year—sometimes for durations of 100 hours consistently. In order to support that we need to make certain that as the requirements on them change and evolve (and they will depending on how the operations are going) we can look at how we might reflect changes within a system, specifically when we look at Watchkeeper, in order to support those. One of the most significant benefits of this particular UOR—and in the MoD we call it "lines of development", so we mean the infrastructure, the training, the way they deploy them at CONOPS—we have started to learn very significant lessons out of these particular operations and how they might be reflected on Watchkeeper. What we are doing all the time is talking to the military; we are talking to our guys in theatre; and we must remember that we actually have a small team out in each theatre supporting the guys, so when there are technical challenges we are in a strong position to make certain that we can address those issues very quickly. From that perspective we are learning 24/7, and it is 24/7; every day of the week something else is coming back. We also get involved and we work closely with the regiment down on Salisbury Plain, attend regular meetings and we work closely together to make certain this thing works in the best possible way for the guys on the ground.

  Mr Miller: This is a fundamental capability that is being provided. Feedback from operations have said that this is extremely advanced, and an enhancing capability. It provides full motion video; and an electro-optic and infra-red camera is onboard the unmanned vehicle, and provides that video and intelligence throughout the battlespace command for the land-based commander, both through forward air controllers, through remote viewing terminals or laptops, but also into the ground infrastructure in both theatres. So it is providing that battle-winning capability with electro-optic infra-red intelligence.

  Q201  Mr Havard: You said 9,000 hours, on how many frames?

  Mr Day: In each theatre we have five aircraft. Basically how that operates is we keep pretty much two ready to go all the time. That is spread over about four airframes. Occasionally when we have got vehicles down for servicing then we will use the three we have got.

  Q202  Mr Havard: Each airframe will not have done an equal amount of hours, will it?

  Mr Day: No.

  Q203  Mr Havard: In the extreme, one of them will have been used more than any of the others; so you have got an extreme testing, have you, of one or two of these vehicles?

  Mr Day: We keep very, very detailed logs associated with the air vehicles themselves, the ground stations, the data links and the sensors. We know exactly how many hours we have got on each of the platforms in each of the key equipments. In terms of the environments, that has been one of the most significant areas of learning for us all. I give you two examples: when we originally deployed the equipment into theatre last summer they pushed the boxes off the back of the aircraft into Iraq and immediately were met with 50 degree plus temperatures. Today that is outside of the specification of most UAV systems—clear to about 49 degrees. The moment we arrive—55 plus degrees—everything is thermally stressed. In Afghanistan one of the most significant challenges, although it is not immediately apparent, is that the whole country is covered in a very fine dust. What does that mean to us? It means with things like computers and laptops you have to clean filters twice a day. You can imagine, on a piece of high technology equipment that changes the way you want to do maintenance; it changes the way you want to support the equipment. We then wait five or six months and then we are trying to operate the same equipment in Afghanistan. Today we are now operating in temperatures of minus 10/ minus 15 degrees, significant humidity, so we are working in icy conditions. We are working in temperatures where people on the ground are actually freezing to death, and the system is up there pushing hard and it is delivering to the guys on the ground. Out there we also have issues I think the Afghanis refer to them as "the day of a hundred winds", where up in the mountains the winds are over 100 miles per hour for days on end. The guys have got to plan and be able to operate and use the equipment in those environments, and that is where Watchkeeper comes in. Watchkeeper was designed from the outset to actually address those types of environments and give our guys the best possible chance when those conditions exist.

  Q204  Mr Havard: That is why you are testing off the coast of Wales, no doubt! Have some of these airframes been in both environments?

  Mr Day: At this moment in time we do not generally move platforms or equipment from one theatre to the other; but we actually keep a very detailed log of the equipment in both theatres. We identify all the issues that arrive, and we do have the ability to pull information about the system as it is located in both theatres.

  Q205  Mr Crausby: In a recent article in Jane's Defence Weekly you said that Hermes 450 was initially seen as a collector of intelligence, but the company was "widening what it can do and moving out to full network connectivity". Can you tell us what that means, and what the benefits and the future will be for UK Armed Forces personnel?

  Mr Miller: The Hermes 450 system is basically a collector at the moment of image intelligence, and provides the basis of that intelligence to the land component. What Watchkeeper brings as a system is much more of a dissemination, communication and network system. What we are learning from the Hermes 450 is how we grow that path towards the full integrated system where the information is passed throughout the intelligence. Hermes is a collector; is providing the right imagery, down to the right ground operator at the right time; but the next step forward is to pass that information to all the necessary players across ground infrastructure, across air vehicles, across all the different land component commanders. There is a difference between the collector system of Hermes and the Watchkeeper system of the future; which is why the ground infrastructure is so important in Watchkeeper.

  Q206  Mr Holloway: What are we actually doing? How are we using it in Iraq that is different from Afghanistan? Presumably in Iraq it is mainly for intelligence; and presumably in Afghanistan it is being used far more for targeting?

  Mr Day: In Iraq today its predominant role, as you rightly identify, is just intelligence; and a lot of that is gathered pretty close to where the guys are based around Basra. Effectively it feeds its imagery straight into the main operating base, straight into where the commanders require it. In Afghanistan the CONOPS, the way the military use it, are different; in that it has several roles. It performs a similar role to that in Iraq, but it has the additional roles of supporting our guys when they enter complex and difficult scenarios. The greatest attribute of a UAV is to give the commander on the ground a bird's eye view of actually what is happening on the ground. The vast majority of operations will request that the Hermes 450 is over the top and giving that information. The way it works is, we have the ground station back in Camp Bastion, which could be up to 150 kilometres away, and they are responsible for mission controlling it, and they will actually receive what we call the primary information, the primary imagery. That is linked via several networks into the commanders that are fundamentally in command and control of the operations. They receive that pretty much real time, within just a matter of a second or so. Where it gains its most significant value for the British Army is to the guys that are actually in contact. How we can provide support to them is they have something called a "remote video terminal", which in reality is just a television screen, a manned, portable television screen with a simple antenna; and those guys on the ground are actually seeing what the aircraft is actually doing overhead. They get a clear view of what is going on in compounds. They get a clear view of what is going on over the hill. They get a clear view of what is around the corner. For the guys just about the enter that difficult compound, not knowing what is around the back of that wall, what is likely to be hiding in the corner, they get a clear view before they actually enter that building; and that is fundamentally one of the key roles that Hermes 450 is fulfilling at this moment.

  Q207  Mr Jenkins: I understand, I think, but could you make it clearer for me. I get the feeling that the bigger the platform we produce the more stuff you are going to bolt onto it until the thing will not fly, and then you take the last bit off and it flies. When I see these soldiers coming out with the little model aircraft and sending them up and around, that can go around the compound and take pictures and send the pictures back. Of all the platforms we have got and are developing, I did not realise the Hermes 450 was called the 450 because it weighed 450 kilograms, so that is a big machines and we can bolt more bits on. What does the military want; what can they use; what is the bottom line? Is it a full video streamed down; is it infra-red? What is the machine and platform that would take the necessary capability? If you take us from the small one, through Hermes to Watchkeeper, will you tell us why each one is important and what it actually does and try and make it so I can understand it?

  Mr Day: I will start, if I may, and take us on a journey from the small, the mini UAVs. We have only got two effective capabilities in theatre. We have only got two air vehicles on the Hermes 450 that can be used with operations. They tend to use those for the more complex operations. At the end of the day, there is a lot of activity going on by the guys in the infantry who are walking the ground who actually want to know, in very quick time, what is immediately ahead of them. That really means they have got to have command and control of it themselves. They have got to be able to hand-launch it. He wants to know what is 200 metres down that road; so he hand-launches his little UAV and within 25-30 seconds he knows what is ahead of him. That is what the mini UAV gives him. It gives him an ability to have command and control, and for him to actually be able to use that air vehicle to gain that information extremely quickly; but it places constraints on the system. It means it has to live with the infantry, the guys who are actually walking the streets on the operation. He cannot push around a 450 kilogram air vehicle; he needs something that can live in his pack—and that is where minis come from. When we are talking about operations in urban environments, built-up areas, little mini UAVs are absolutely the right thing to have. The key message to get across there is the mini UAVs can normally have a daylight sensor, just like normal televisions at home, or a thermal imager; they cannot have both. They do not have the ability to lift both sensors. If it is night-time you have got to sit there, break it apart and put a thermal on it. If it is daytime you put the TV on it. The other thing is, because they are model airplanes, and if any of you have seen model airplanes fly, they are not very stable; so the imagery is not particularly good, but it gives you the snapshot, and it gives you that bit of information that may make a difference. As we go up the tree, the big driver for moving from minis, to slightly larger platforms, to a Watchkeeper, is all about the quality of the imagery and the range at which we can operate it. Now we are talking about a sensor that is very stabilised, that can sit and look at my face for 12 hours of the day; it can move very quickly through the environment, perhaps a speed of 100 knots, perhaps less. The little minis do 30 or perhaps 40 knots so they are a lot slower. The big platform also has the ability to carry other sensors, and the one I would like to talk about is something we call "synthetic aperture radar". What that really means, it is a radar that gives us an image that looks pretty much like something you would see on a television; it gives you an image. The real attraction is, when there is cloud most television cameras cannot see through cloud—no ability at all; you can leave your air vehicle on the ground—cloud, fog or mist, no capability at all. You put synthetic aperture radar on it and it sees through cloud; it gives the guys a clear image of everything that is stationary on the ground. We then link it to another bit of technology that allows us to see everything that is moving on the ground. Those radars weigh about 40 kilograms as a minimum. The moment you say to me, "Chris, we now want to have that imagery in those poor conditions", I need a larger platform to lift it in the air. I am talking about lifting half a man. I cannot do that with a mini; I need a bigger platform. You can start to see that the critical variable with UAVs—that is the air vehicles themselves—is the more payload you want, the larger the air vehicles. I have a little equation in my head that says, "Depending on your payload size, the payload you represent is between ten and 20 per cent of the platform mass". If you want a 40 kilogram sensor you probably need an air vehicle of about 400 kilograms. The more sensors you want, the more capability, the larger the general platform. The other driver that links to things the Americans do is they like to fly higher. Little mini UAVs, those poor little television sensors, they are only good from about 300 or 400 feet to a 1,000 feet above the ground; if you fly higher than that imagery is not very good. You might say, "I want to fly at 5,000 or 10,000 feet", but you need a better sensor, so you move into the Hermes system. If you have then got a very large platform like the Predator, the Reaper or the Global Hawk, they operate at significantly higher altitudes, and one of the reasons is they carry a very significant sensor sweep. They have to operate higher in order to keep them safe. Those are the sorts of variables which define where you pitch your UAVs.

  Mr Chavez: Just to add to some of the key variables, Chris touched on persistence—the ability to remain on-task for very extended periods of time—when you are actually gathering intelligence you will frequently want to watch one locality for 24 hours a day: you cannot do that with a mini UAV. The other thing is to do it in a totally undetected manner. You need to get your UAV up to an altitude where it is not visible and it cannot be heard; and, again, mini UAVs just cannot do that. Things like Hermes 450 and Watchkeeper are designed to operate so you can see and gather very usable intelligence without being detected at all for very extended periods of time. You can watch that building and you know that the white Mazda that drove in has been parked there, a person got out, nobody else has gone into that building and then he gets back into the White Mazda and he drives off 12 hours later. It is that sort of long-term persistent ISTAR that is very important.

  Q208  Mr Holloway: It might be very interesting to visit Mr Day's team when we are in Afghanistan if there is time. Mr Miller in his excellent article referred to "imagery exploitation". Just quoting from Mr Day again, in Afghanistan is there a conflict with the use of this kit between, for example, the JTAC teams that are in contact and the higher commanders who always want to know exactly what is going on? Also, to what extent can the troops in contact dictate or request where the machine should be looking in order for them to get rounds on the ground from indirect fire weapons or aircraft?

  Mr Day: In terms of the overall way the MoD uses their CONOPS, this is another driver behind the way that the MoD has structured UAVs with the minis, the tactical and the more strategic; that, at the end of the day, Watchkeeper or the H-450 is a brigade or a battle group commander's assets. Basically what will happen is the commander will say, "You have that asset for the duration of that particular activity". So there is no conflict with higher commanders wishing to take it away. It has been dedicated to that commander for his particular operation and he has command and control over it. The way that it operates at the moment: at the end of the day it is about the guy who is in contact; it is about the guy who wants to look inside that compound; and the way he achieves it is through things like our Bowman communications. He has a means of talking back to the HQ to say, "Okay, guys, the aircraft's not in the right position; we're not seeing what we want. Can you move it left a little bit; right a little bit; or, will you hold on where you are?" That is basically how the commanders in the field use it today. If, as a consequence, a higher priority issue came along and there was a debate and they said, "Look, guys, we've got a more significant issue happening elsewhere and we want to redeploy your assets", what might happen is the commanders in the field would default to their minis and accept the penalties of the poorer imagery and the shorter range.

  Q209  Mr Holloway: The JTAC teams then effectively have to talk the surveillance asset onto the target in the same way in the old days you had to talk aircraft onto a target. In the development of Watchkeeper, is this a kind of thing you might try to integrate? If so, are there likely to be any delays? I would have thought it is quite important to give the guys electronically on the ground some way of positioning it in the right place and then calling for whatever they want?

  Mr Day: People often ask me the question, "What is the difference between 450 and Watchkeeper?" It goes back to the Chairman's first question actually, which is: how do we find UAVs? Is this the right question we are asking? UAV aircraft have been around for a fair amount of time and we have a pretty comprehensive understanding of them. One of the key differences for Watchkeeper is how we integrate the whole system into the rest of the UK infrastructure, the COMMS, the air traffic management, the logistics chain. That is what Watchkeeper brings to the UK. Today the MoD is looking at various ways of achieving that. One way is that most commanders in the field have a Bowman radio of some form or another, which is both the voice and the data. One of the things we have been looking at, and working with MoD on, is a guy can have a simple map display of exactly what is going on, with a clear lay-down of who is where and what is going on. That guy can tap on that screen and potentially say to them, "I want to view that particular geographic point on the ground". He can then identify where he wants that to go, which could well be the Watchkeeper ground station, and that information is then sent back via the Bowman network to the guys in the ground station and they can react accordingly.

  Q210  Mr Holloway: In the future it is likely that we will be dealing with rather more sophisticated enemies than tribesmen in southern Afghanistan. To what extent are you putting on equipment and ensuring that people could not electronically disrupt our UAVs in the future? Obviously you will consistently update it, but is it a consideration now on the equipment we are getting, in case we have to move it from Afghanistan to somewhere else?

  Mr Day: Watchkeeper itself when it was originally conceived was thought about as 15 years for the platform and 30 years for the system life. We had to consider that, like everything else in the military domain, as people understand the technology they find ways of countering it. We have done things within the system to specifically make certain that, as these issues arise—and I will give you one particular example—on Watchkeeper the data link is encrypted, so it has got a high grade encryption on that which will inhibit some of the very issues that you mention. Also, in addition, we have done some clever things with the data link to effectively bury it in the noise within the ether, rather than make it stand out like a particular electromagnetic lighthouse. We also look carefully at things like the noise it makes; and we pay particular attention to silencing the engine. We look carefully, and we will look carefully, at the next evolutions at how we would use all its signatures. Yes, you cannot enter the UAV field today expecting that your technology is going to last particularly long. You have got to make certain that as you understand as an organisation, and this is one of the key strengths of Thales, we do have a significant knowledge base, across a significant area of technology, we can pull that into these sorts of programmes and give us a future-proof solution.

  Q211  Mr Hamilton: Are there any additional things that Watchkeeper does you have not already mentioned which are better than Hermes 450?

  Mr Miller: This is really key. There are two elements of Watchkeeper that are different from the Hermes. There are the advancements in the air vehicle itself; and of course there is the network ground infrastructure which we have been talking about. The air vehicle itself is a dual payload configuration, so it can take the EO/IR camera as well as the radar together—electro-optic and infra-red—and additionally more sophisticated SAR GMTI radar. It has an all-weather operational capability; so it has de-icing systems built in. It has got enhanced structure integrity with an adapted wing fuselage construction. Autonomous flight capability and auto take off and landing. Of course, the additional maintenance and access to subsystems is improved. The advanced duplex avionics on board and the enhanced landing gear. So there are many aspects within the air vehicle of a significant difference. On the ground infrastructure side you have got the exploitation, communication dissemination that we discussed as a fundamental difference of the Watchkeeper system; and of course dual data links; the ability to pass information securely around the battle space. All this is required because Watchkeeper has got to provide a worldwide capability. Armed Forces can be deployed anywhere in the world and in climate conditions that are different from current theatres. Of course it has got the ability to be flexible for additional operational sensors in the future. You can see we have built into the growth future of Watchkeeper not only the air vehicles but also the ground network enabled infrastructure.

  Q212  Mr Hamilton: At the evidence session on 6 May we were told that the MoD was fairly hopeful that the in-service date would be achieved towards the end of 2010. Are you confident that is going to be achieved?

  Mr Day: Yes, today the programme is on schedule and we look to deliver the capability into MoD on that date.

  Mr Miller: We are very pleased actually because, since our Contract award in 2004, we have achieved the design phase; we have been through all the critical design reviews throughout 2006/07; we have met all the milestones for the Watchkeeper programme; we have achieved our first flight of the new Watchkeeper air vehicle in April this year; we are now starting the integration phase and testing; it is currently going on and will eventually come to the UK at Aberporth at the end of this year, beginning of next year, ready for the 2010 in-service date as planned.

  Q213  Richard Younger-Ross: This is obviously a great advantage for our Forces, to have this ability to see behind walls. Even on a simple basis it cannot be long before even in a place like Afghanistan that Afghani forces should not have their own device which will try to spy on our Forces. If we come across a more sophisticated foe then certainly they will have UAVs to spy on our Forces. Are you developing countermeasures against UAVs for spying?

  Mr Chavez: Perhaps if I take that as a question because it relates to broader military capability. Certainly one of the developing threats that Armed Forces see around the world is the threat of UAV systems being used widely against them. The traditional response to that comes from enhanced air defence systems. Thales, for example, in Belfast have been responsible for modifying the Starstreak air defence system to adapt it to work with smaller radar across section targets, because UAVs do present very difficult targets because they are so small; they have very small amounts of metal in them, so they are very difficult to see on radars, and missile systems, because of their size, find it difficult to hit them. The traditional response is to actually look at upgrading your air defence systems, and that is what we have been doing using the Starstream missile.

  Q214  Richard Younger-Ross: The sort of foe we may face which we are trying to use UAVs against would have the same difficulties in trying to detect you?

  Mr Chavez: Absolutely. The survivability issues, as Chris touched on with Watchkeeper, have been very carefully thought through. Indeed, when you actually come to mission planning—because you do not just launch a UAV and pilot it, typically with Watchkeeper one of the major advantages is that you can actually set the mission plan—you are not flying the aircraft round the sky, but saying, "I'm interested in surveying this area of land", and the aircraft will go off and it will steer the sensor, rather than you fly the plane. It will automatically go off on that track. There is a lot of automation in how we extract that information.

  Q215  Chairman: Just a brief question about trialling the Watchkeeper and flying it in UK airspace. Are your discussions with the Civil Aviation Authority going well? Is there an issue about delay or anything in terms of the extent to which you can trial the aircraft?

  Mr Howe: Could I comment on that. This, of course, is a subject on which it is the MoD, rather than us, which is leading. The MoD, as I understand it, is putting together a proposal in relation to air space which it is in discussion with the CAA about. We, of course, are very interested in the outcome of that; but we are not, as it were, the sponsor or owner of that process. As I understand it, there is a fairly elaborate process for considering changes to air space arrangements; the CAA is quite well advanced with that. The next stage, I believe, is public consultation about the sort of solution the MoD has been proposing. I believe that is likely to start quite shortly; I do not know precisely when.

  Q216  Chairman: But you would not describe it as a significant clog in the process?

  Mr Howe: I do not think so, no. It is a significant issue but I do not think it is a clog in the process. I think it is being addressed sensibly and very methodically and thoroughly, and we will get through the process.

  Mr Miller: There are two aspects: this is permanent airspace change which is being discussed; but you can at the moment fly in temporary restricted airspace. For instance, in 2005 we flew the Hermes at Parc Aberporth in a temporary restricted airspace; and we could do that now if we wished in consultation with the CAA. There are two differences between what we can do now—controlled and permanent air space change that John was talking about.

  Q217  Mr Hamilton: You indicated, Mr Chavez, that Israel has developed the Hermes 450. Will the UK be able to maintain and upgrade the Watchkeeper as we move forward; and will we be able to work independently?

  Mr Chavez: Absolutely, and that was entirely behind the reason we created a joint venture in Leicester which holds the intellectual property.

  Mr Howe: Held here in the United Kingdom. Watchkeeper is being built in the UK, whereas Hermes 450 is an Israeli product.

  Q218  Mr Jenkins: One thing that strikes me, Chairman, is that you have built this new Watchkeeper platform that you bought in bits and pieces: why did we not go for the American Global Hawk? Is that not a better platform? Would it not have carried all your sensor equipment? If we had got the basic platform from America the deal with have been done now, and it would have been trialled and proven airworthiness, and it would carry the loads you want of Watchkeeper. Why did we go down the Watchkeeper route?

  Mr Chavez: They are very different classes of UAV and they are rather different. The Reaper UAV is much more similar to Global Hawk. It is quite clear, the Watchkeeper competition was an open competition. There was a competition with UAV systems offered by Lockheed Martin, Northrop Grumman and BAE systems as well as ourselves; so it was a truly international competition against the Watchkeeper requirement. It comes back to this: there is a significant difference between how you use these three different levels of UAV. It is an operational concept issue.

  Q219  Mr Havard: On that point, what about weaponising this thing; because then it does become a very different vehicle, does it not; and the point about its use and airspace becomes a different set of questions. In summary, we are having bits of material flying about that might bump into one another, but if they have not got explosives on them it is less of a problem than if they have. Is it able to do that? Reaper does that; is Watchkeeper going to do that?

  Mr Howe: If I may, I think that is really a question for MoD rather than us. We are not under contract to provide a weaponised UAV. We are providing an intelligence gatherer. Obviously vehicles that can fly could well have the potential to carry weapons; but we have not been contracted to do that—that would be in the future. The question about the military requirement is for MoD rather than for us.
