Earl Attlee
My Lords, I start by thanking the noble Lord, Lord Judd, for securing this evening’s debate and other noble Lords for their contribution. Your Lordships will note that the question is about civilian as well as military use of these aircraft and the House will be aware that I answer for all of Her Majesty’s Government. I share the regret of the noble Lord, Lord Tunnicliffe, about the number of speakers and am grateful for his very measured contribution to our debate.
First, we should understand that we are talking about remotely piloted aircraft systems, or RPAS. We are most certainly not talking about “drones” as exemplified by the “doodle bugs” of the World War II era. The location of the cockpit does not change the essential function of a professional, qualified pilot in terms of his or her direct responsibility for the safety and overall management of a flight. I do not foresee a situation where a human’s ultimate responsibility for the safe flight of a remotely piloted aircraft will be replaced by fully autonomous technologies.
I will follow the split of the noble Lord, Lord Tunnicliffe, and cover civilian RPAS operations first. These are closely regulated by the Civil Aviation Authority and are treated in the same manner as that of an equivalent manned aircraft. This applies to all aspects of unmanned aviation, from the initial design and construction, or airworthiness, through to the safety requirements of how it is flown and operated. This viewpoint is shared internationally. We certainly have no intention of denying access to UK airspace—we just want to keep it safe.
Small unmanned aircraft are those under 20 kilograms weight, flown at short range and always within the sight of the person flying them. These are overseen to a lesser, but proportionate, extent by the CAA but, in certain circumstances, such as for commercial use, a permission is needed. They are also subject to the Data Protection Act and the Regulation of Investigatory Powers Act. The noble Lord, Lord Tunnicliffe, talked about intrusion. He will be aware that the activities of Google also cause similar concerns and that this concern is not unique to RPAS.
The House should not overlook the technological importance of the growth of the remotely piloted aircraft sector. For example, systems which can be used to detect other aircraft could, in time, greatly assist all pilots, in the same way that aircraft transponders have contributed to safety across the sector. I would point out that the UK’s ASTRAEA consortium is at the forefront of international efforts in this field. The noble Lord, Lord Judd, told the House about a wide range of uses including anti-poaching operations. Noble Lords will have read the article in this week’s Sunday Times about the use of RPAS to assess the health of a vineyard in France—a very commendable use, I would suggest. Surely, this is the start of yet another technical revolution facilitated by the ubiquitous modern electronics. The noble Lord, Lord Judd, is right of course when he says that the potential for their development is considerable.
The overall objective of the Government and the European Commission is to enable the full and safe integration of remotely piloted aircraft into the total aviation system so that they share the same airspace as their manned counterparts. With UK and EU input, the International Civil Aviation Organization is currently developing RPA guidance material, due for publication in autumn 2014, with standards expected about two years later. Within Europe, the Commission’s RPAS roadmap, published on Thursday 20 June 2013, is aimed at an incremental integration of RPAS into European airspace from 2016. To achieve this, there are a number of significant technical challenges to be overcome, primarily concerned with ensuring the RPAS is airworthy and has the capability to avoid collisions. However, until the technological and regulatory hurdles can be safely overcome, operations of larger remotely piloted aircraft will continue to be restricted to segregated airspace. For these reasons, therefore, my view is that there is already a suitable framework in place to regulate the operation of civilian remotely piloted aircraft and that no additional codes of conduct are required.
I now turn to the military element, which I suspect is of more concern to the House. Although the MoD operates a number of unmanned aircraft systems, Reaper is the UK’s only armed remotely piloted aircraft system and its only operational use is in support of UK and coalition ground forces in Afghanistan. Although predominantly used for intelligence, surveillance and reconnaissance tasks, the aircraft is also armed with precision-guided weapons, which offer an attack capability if needed by ground commanders. The system is operated by highly trained, skilled and qualified RAF pilots in accordance with the principles of international humanitarian law and the UK’s rules of engagement, which are identical to those used by crews of manned combat aircraft. That applies even for joint operations with US forces.
The UK’s selection and prosecution of all targets is based on rigorous scrutiny. Targets are always positively identified as legitimate military objectives and every effort is made to ensure that harm to civilians or damage to civilian property is minimised. The Government have a longstanding policy of not divulging the detail of our rules of engagement; that would give our adversaries useful information about how and when we might choose to use lethal force. I also gently remind the House that the pilots operate under military discipline. Similarly, the RAF has well established command, control and supervisory frameworks that I have seen on exercise. I do not believe that anything extra needs to be provided for.
The noble Lord, Lord Judd, suggested that the UK military has 500 RPAS. However, there are currently only five armed RPAS. Of course, rather smaller RPAS are used for tactical surveillance. The use of remotely piloted aircraft systems is no different from other airborne or indeed ground-based attack systems. The only difference from a traditional aircraft is that their cockpits are on the ground. The systems can only launch their weapons when specifically commanded to do so by the pilot. They do not have the capability to launch any weapons autonomously. In addition, there are no future plans to replace military pilots with fully autonomous systems. I know that that is a matter of great concern to the noble Lord, Lord Judd, and the whole House. The MoD has no intention of developing any weapons systems to be used without human involvement. Although the Royal Navy has defensive systems such as Phalanx that can be used in an automatic mode, to protect personnel and ships from enemy threats like missiles, a human operator oversees the entire engagement. Furthermore, all our remotely piloted aircraft systems used in Afghanistan to protect troops on the ground are controlled by highly trained military pilots. There are no plans to replace skilled military personnel with fully autonomous systems.
Lord Judd
I am extremely grateful to the Minister for this reply. Could he clarify what is meant by “no intention” to deploy these vehicles other than with human involvement? What does human involvement amount to? How much automatic action in terms of analysis, identifying a target and deciding to hit it will be left to the device in future vehicles once they are launched?
Earl Attlee
My Lords, the answer is currently none. It requires human involvement to launch the missile at the target. RPAS cannot currently engage a target without being commanded to do so by the pilot on the ground.
The noble Lord, Lord Judd, implied that communication with and control of an RPAS could be lost in the event of an electromagnetic pulse. If that was the case, the RPAS would probably lose all its capability, just like any other aircraft.
The noble Lord touched on the perceived disadvantages of the military use of RPAS. As of 20 June, the UK Reaper RPAS has employed 394 precision-guided weapons. There has been only one known incident that resulted in the deaths of civilians. On 25 March 2011, an attack on two pick-up trucks resulted in the destruction of a significant quantity of explosives and the deaths of two insurgents but, sadly, four Afghanistan civilians were also killed. In line with current ISAF procedures, an ISAF investigation was conducted to establish if any lessons could be learned or if any errors in operational procedures could be identified. In that case, the report concluded that the actions of the Reaper crew had been in accordance with extant procedures and rules of engagement.
The noble Lord, Lord Judd, asked if the UK had conducted any targeted killings and whether the UK uses the ICRC definitions of combatants and civilians. Her Majesty’s Armed Forces will engage the enemy in accordance with international humanitarian law and the UK rules of engagement. The necessity and legality of engaging the target does not depend on the means of doing so. The noble Lord stated that we either uphold the rule of law or we do not. He is right. I can confirm that Her Majesty’s Government uphold the rule of law. How the US Government conduct themselves is not a matter for me to comment on and I have already touched on joint US/UK operations.
The noble Lord, Lord Tunnicliffe, talked about the remote warrior. Our experience of operating the Reaper remotely piloted aircraft system in Afghanistan suggests that Reaper aircrew are just as if not more connected to the situation on the ground when compared to operators of other aircraft types. That is because they fly missions over Afghanistan for years at a time and not in short-duration rotations. Remotely piloted aircraft can loiter over areas of interest for a considerable time, providing that much-valued intelligence picture. I remind the House that surveillance is their primary role. Should an attack be requested, their persistence enables them to assess a target in detail and select an optimum time for attack that minimises the risk of civilian casualties. Indeed, because of this increased awareness of the ground situation, enabled by the connectivity that a ground-based cockpit offers, there have been many occasions when crews have elected not to fire a weapon.
I will say a few words about the ASTRAEA project. ASTRAEA—Autonomous Systems Technology Related Airborne Evaluation and Assessment—is a UK industry-led consortium focusing on the development of technologies, systems and procedures with a specific emphasis on unmanned aircraft systems. The consortium is led by seven UK companies—AOS, BAE Systems, Cassidian, Cobham, Qinetiq, Rolls-Royce and Thales—plus a further 70 SMEs and universities. The aim of the programme is to enable the routine use of UAS in all classes of airspace without the need for restrictive or specialised conditions of operation. The £62 million programme was split into two phases, each lasting three years. Phase 2 ended on 31 March 2013. Some 50% of the funding came from industry partners, with the remainder from government—the TSB and the regions. Future activity under the ASTRAEA brand is the subject of ongoing discussion within the consortium.
I welcome this debate, which has explored the application and use of remotely piloted aircraft. The noble Lord, Lord Judd, is right to question the implications of any new and growing technology such as this. To reiterate: RPAS are aircraft under human control. The very clear regulations and guidance that apply to aircraft also apply to RPAS. I am confident that no further code of conduct is required.
