Unmanned Aerial Vehicles

Debate between Philip Dunne and Anas Sarwar

Tuesday 11th December 2012 Westminster Hall

[Mr Dunne]

The hon. Gentleman is seeking to jump some way ahead. The aircraft carrier will not be deployed in its full air strike capability until 2020. The main gate decision on the T-26 is not until the middle of the decade, so he is asking me to foresee military capability several years away. He may not be surprised that we are at least contemplating trialling some capability for future use at some stage. I will not be pressed further on that point, but I will address some of the issues that the hon. Lady mentioned. I want to continue setting the scene for a few more minutes.

The Reaper system, which is the UK’s only armed RPAS, is flown by professional pilots who remain in full control of the aircraft at all times; they follow the law of armed conflict and the UK rules of engagement in exactly the same way as pilots of manned aircraft. Reaper, as with other forms of RPAS, is primarily used for intelligence surveillance and reconnaissance, but through technological advance it has been enabled to be armed with precision-guided weapons, thereby meeting a secondary military requirement.

The decision-making process leading to the identification and engagement of a target by one of the two weapons systems available to UK Reapers is identical to that of conventionally manned aircraft, but the greater access to information through a combination of the aircraft’s onboard sensors, ability to access off-board information and duration of missions enables them to be deployed before engagement. Reaper pilots are, arguably, the best informed and connected of all air crew in this operating environment. They are well placed to provide battle-winning surveillance and engagement capability to meet UK ground forces’ needs.

The Reaper was fielded in 2007 and as of 1 December, despite more than 42,000 hours flown over Afghanistan, it has fired only 360 weapons—52 laser-guided bombs and 308 laser-guided Hellfire missiles. Of those precision-guided weapons on Reaper, the type employed is carefully selected in every engagement, which ensures that the most appropriate munition is used to deliver the required effect, in a proportional manner, thus minimising the risk to civilians and their property. The sophistication of the weapons also provides the ability remotely to change the course of the weapon post release, which is another example of the many steps taken by RPAS to avoid civilian casualties as collateral damage.

I am aware of only one incident where civilians have been killed by weapons deployed from a UK Reaper. As I mentioned last month, on 25 March 2011, there was a strike on two pick-up trucks in Afghanistan carrying a significant quantity of explosives, which resulted in the death of two insurgents and four Afghan civilians. That incident was highly regrettable. The subsequent report did, however, confirm that the actions of the Reaper crew had been in accordance with extant procedures and UK rules of engagement. Every weapon released by the UK’s RPAS is under the command of a professional pilot bound by the UK rules of engagement.

Touching on a point raised by the hon. Member for Hayes and Harlington (John McDonnell) about the psychological considerations of operating the Reaper, the experience thus far suggests that far from being detached from the reality of the situation, Reaper air crew are just as connected to the situation on the ground as operators of other aircraft types. They have increased information available to them, a longer time to study the information and the ability to abort the mission even after they have fired the weapon. The increasing specialisation of the role of flying RPAS is being considered by the RAF for recognition as a distinct skill within the flying service.

Of course Reaper is not the only RPAS operated in Afghanistan. To correct the hon. Member for North Durham (Mr Jones), there are in fact five types—not four—of unmanned aircraft systems in operation. As I have already mentioned, Reaper is the only armed version, but we have also deployed the Hermes 450, which has already flown 65,000 hours for intelligence, surveillance and reconnaissance purposes. It will be replaced by the more modern Watchkeeper, which again is for surveillance purposes and is not armed. In response to the question put by the hon. Member for Birmingham, Edgbaston about Watchkeeper, training is already under way and we expect the system to replace Hermes during 2013. These and other smaller deployed tactical systems being operated by Army units in Afghanistan form part of a mix of airborne ISR capabilities, of which they are but one, albeit increasingly important, component. They complement the more traditional manned surveillance capabilities provided by our other aircraft types. Looking further ahead, technological advances are likely to increase the level of automation in some systems, just as in other non-military equipment, but I stress the point that the Government have no intention of developing systems that operate without human intervention in the weapon command and control chain.

Let me turn to the other specific points mentioned by the hon. Member for Birmingham, Edgbaston. On the main thrust of her remarks on the moral and ethical considerations, it would be instructive for her to look at the joint doctrine note 2/11, if she has not done so already, to which the hon. Member for North Durham referred. It was published in March 2011 by the Government, and was the first Government sponsored document to go into the UK’s approach to unmanned aircraft systems. It has a specific section on moral and ethical considerations, which inform the rules of engagement and the operations in which we are engaged at present.

[Anas Sarwar]

The Minister has quite rightly outlined the moral and ethical use of drones by the UK Government. What discussions have we had with our allies to ensure that they are applying the same principles?

[Mr Dunne]

As is standard procedure, I am here to answer for the UK Government use of unmanned air vehicles. Other countries that use such systems have their own rules of engagement, as is the case for the UK. We do not publish rules of engagement for the sensible reason that to do so would risk prejudicing the capability, effectiveness or operational security of our armed forces, and that is also the doctrine applied by other countries.

The hon. Member for Birmingham, Edgbaston asked about the military chain of command and whether it would be retained. We have no plans in the Ministry of Defence to operate any of our facilities outside the military chain of command. The hon. Member for Dunfermline and West Fife referred to potential civil uses in the future for airborne surveillance equipment; the hon. Member for Strangford (Jim Shannon) referred to offshore fishing. It is conceivable that in due course other Departments might find other uses for the technology, but I am not aware that it is something that the MOD is engaged in at present.
