Long delays, cost overruns and as yet unable to carry munitions, the Protector drone shows the UK is as bad at military procurement as ever.

While drone warfare continues to rapidly develop and evolve, the Ministry of Defence (MoD) has revealed in an FoI response to Drone Wars UK that the UK has received just nine of the 16 Protector drones ordered from US company General Atomics a decade ago.

Originally announced by David Cameron in 2015, the UK ordered 16 of the upgraded version of the Reaper drone in 2016 (with an option to buy ten more).

Called SkyGuardian by the manufacturer and other users, the drone has been renamed ‘Protector’ by the MoD in an apparent crude attempt to manage public concerns about drone warfare. The whole life cost of the 16 drones was initially put at £704m, but by mid-2025 this had risen to £1.46bn. It has no doubt risen since. 

The UK’s procurement of the ill-fated Watchkeeper drone – where the British Army spent over £1bn for a drone that saw almost no service and regularly crashed – was a textbook example of poor UK procurement.  Ahead of the publication of the Defence Investment Plan (DIP),  which we are told will commit billions more on drones and AI warfare, the Protector programme shows that the UK is as bad as ever at procuring these systems.

Missing Milestones

Slated to be in service in the early 2020s, the first Protector drones arrived in the UK in 2024 for testing and training,  and a year later, in June 2025, the RAF announced that four Protector drones had entered service with the RAF.  However, although ‘in service’, the MoD admitted that Protector had not yet reached ‘Initial Operational Capability’(IOC) and the FoI response shows this remains the case:

“Protector RG Mk1 has yet to reach all Initial Operating Capability (IOC) programme milestones. These milestones are currently under review, and a revised IOC date is expected post release of the Defence Investment Plan. However, Protector has already deployed on operations and is providing valuable Intelligence, Surveillance and Reconnaissance support on Operation SHADER.

Failure to reach Initial Operational Capability is likely to do with the number of drones in operation, the number of crews currently trained to operate them and/or the fact that it has not yet been approved to launch munitions (see below).  In response to a parliamentary written question in February which sought details of the number of drones needed to be flying for it to pass that IOC milestone, MoD Minister Luke Pollard refused to answer, stating that

“The milestone is clearly defined and the Ministry of Defence is working to ensure the necessary supporting requirements are in place so that it can be met at the earliest opportunity.”

According to the new FoI response, however, the milestones are “currently under review” giving the impression that goalposts may well be moved.

Protector now flying ‘in the Middle East’

In September 2025, the MoD announced that the UK’s MQ-9 Reaper had been withdrawn from service after more than18 years of operations, firstly against the Taliban in Afghanistan (2007-2014) and then ISIS in Iraq and Syria (2014-2025).

In October 2025, two RAF Protector MQ-9B were spotted on flight tracking sites flying from RAF Akrotiri over the Mediterranean on apparent training exercise. This was the first overseas deployment of the new drone. Several weeks later the drones were then spotted flying over Israel and Jordan, apparently on their way to Syria as part of Operation Shader, taking over the role that Reaper had previously undertaken in that never-ending operation.

On 1 March 2026, two days after the US and Israel began attacking Iran, a small drone struck RAF Akrotiri.  Following the suggestion that the drone had originated from Lebanon, it was reported that the RAF’s Protector drones were patrolling off the coast of Lebanon to warn of any further incoming drones attacks. The Protector drones were, however, unable to ‘protect’ by shoot down any incoming drones or missiles as they had yet to be cleared to carry weapons. Subsequently, the drones been spotted flying over Lebanon transiting to Syria.

While the UK’s Reapers were known to be based in Ali Al Salem Air Base in Kuwait for Operation Shader (although this was never officially acknowledged), the UK’s Protector drones appear now to be based at RAF Akrotiri for these operations.  The FoI response states that the UK’s nine Protector drones “are currently split between RAF Waddington and the RAF forward operating location for Operation SHADER.” RAF Akrotiri is obviously closer to Syria than Kuwait, where the UK steadfastly engages in military operations against ISIS.   

Unarmed Protectors

The FoI response also confirms that the Protector drones have still not yet been authorised to carry munitions and are restricted to “intelligence, surveillance and reconnaissance support”.

While the exact reason for this remains unclear due to secrecy, MoD attempts to put in place changes to allow drones to conduct bombing training runs at the Holbeach bombing range near RAF Waddington have run into problems apparently due to the on-going risk of using lasers to guide the bombs.  

Recently published documents on the Civil Aviation Authority’s website appears to show little progress being made.  

Revealed: What became of the Reaper

Finally, the  FoI response reveals what became of the UK’s Reaper drones.  There had been speculation that the drones would be handed over to Ukraine for use in the ongoing conflict with Russia.  While initially the MoD would only say that the drones were no longer in service and had been disposed of, the FoI response gave some more details:

When taken out of service the air vehicles were deregistered, de-militarised and dismantled into their ground transportation packing cases and were handed over for disposal by the contractor GA-ASI. One deregistered and de-militarised Reaper has been returned to the UK and is held in storage by the RAF in its packing case while it is considered for future preservation in a museum.

Rather than good money after bad…

The government strongly argues that we need to spend ever increasing amounts on ‘defence’. In 2020/21 UK military spending was £42.4bn but by 2024/25  had increased to £60.2bn (around 2.4% of GDP). In February 2025 Starmer committed to further increase military spending by around an extra £6bn per year – roughly the amount he cut from the UK’s Aid budget – with ‘an ambition’ to reach 3% by the next parliament.  Just months later, at the NATO summit in June 2025, he upped the ante, with a pledge to reach a ‘goal’ of 5%, estimated to be an extra £30bn per year.

Drone Wars UK fundamentally disagrees with the concept of military security arguing that we should instead be investing in human and sustainable security. Rather than divide the world into ‘us’ and ‘them’ – good states and bad states –  we need to focus on building global co-operation and common security and accept that no state can be truly secure unless all feel secure.

Rather than cutting our diplomatic and aid infrastructures, we should be investing much more in diplomacy, aid and conflict prevention structures. Rather than squandering billions on new weapons technology we should be investing in health and social care; investing in greening the economy and tackling climate change.

Many will no doubt suggest this is naïve, the record of UK drone development and procurement programmes  – on which the UK has spend vast sums and in which it is placing its security – is littered with failures from Telemos to Watchkeeper to Taranis to Mosquito and many others.

As the UK’s Protector drone programme limps into service and while the UK is about to spend yet more vast sums on drone and AI warfare, is it not time to try something else?

RAF’s new armed drone given approval to fly freely over UK

The UK’s Military Aviation Authority (MAA) has issued ‘Military Type Certification’ to the UK’s new ‘Protector’ armed drone, meaning that it is now free to fly within UK airspace, including over populated areas.

Previously, for safety reasons, Protector and other large uncrewed systems such as the Protector’s predecessor, the Reaper, were only allowed to fly in segregated airspace, with other aircraft excluded.  Although large military drones are spreading rapidly, as Drone Wars has documented they continue to tumble out of the skies for a whole variety of reasons.

The UK is the first country to certify a large drone to fly freely in unsegregated airspace and General Atomics, the manufacturer of the drone – which they call MQ-9B SkyGuardian rather than UK designation of ‘Protector RG1’– were delighted as it has huge implications for their sales.  The company’s press release called it “a seminal achievement.”  A key element of the  approval, alongside “rigorous testing”, was apparently the ‘rigid separation’ of mission software from flight critical software.

Protector flights in the UK

The Protector has been undertaking a short series of test flights around RAF Waddington, the home of UK drone warfare, over the past few weeks. The Aviationist noted two tests in the past week which were of the longest duration so far, including one which saw the drone fly to RAF Marham before taking off and returning to Waddington.  RAF Marham is the nominated diversion airfield for the drone.

General Atomics reported that 10 of the 16 Protector drones ordered had now been delivered to the UK but it is not clear if these are all at RAF Waddington  as previous drones that have ‘been delivered’ to the RAF remained in the US for testing and trials.  The UK is increasingly secretive about its drone operations and exact details about when Protector is to come into service have been given vaguely as ‘by the end of 2025’.  Reaper is also expected to exit service by the end of the year.

Protector test and training flights are now likely to expand both in number and in range, including flights to launch weapons at Holbeach Air Weapons Range, near Boston in The Wash. Protector carries the Paveway IV guided bomb and Brimstone 3 missiles.

The Ministry of Defence has always been clear that Protector will also be available to support counter-terrorism operations within the UK and undertake Military Aid to Civilian Authorities (MACA) tasks such as assisting HM Coastguard with search and rescue missions.  Read more

RAF’s new armed drones begin test and training flights over UK

The RAF announced that its new armed drone, called SkyGuardian by other users but dubbed ‘The Protector’ by the UK, has begun regular test and training flights in the UK. At the same time, the UK has exercised an option to extend the life of its current Reaper drone fleet which were supposed to transition our of service by early 2024.

The UK ordered up to 26 new ‘Protector’ drones in October 2015 to replace the UK’s current fleet of armed Reaper drones. The new drones were supposed to be in service by 2018 but long delays and cost overruns – estimated to be more than £500m – has dogged the programme.  The MoD confirmed that four Protector drones have now been delivered to the UK.

Protector differs from its predecessor in that it can carry more weapons and fly further and for longer.  However the UK argues that the main advantage of the new drone is that it was built to standards that allowed it to be flown in civil airspace alongside other aircraft.

Rather than be based overseas as the UK’s current fleet of armed drones are, the new drone will be based at RAF Waddington in Lincolnshire and deploy directly for overseas operations from there.

However, the technology that allows uncrewed aircraft to supposedly fly safely in the same airspace as other aircraft has not yet been proved and current Civil Aviation Authority (CAA) rules means the drone must fly in segregated airspace, away from other aircraft.

Drone Wars has long argued that while the use of military armed drones has normalised, they continue to crash at a significant rate for a whole variety of reasons.

Significantly, the new drone has been brought in with the understanding that it can also be used at times of crisis for operations within the UK under Military Aid to Civil Authorities (MACA) rules.  It is perhaps likely then that at a time of crisis, the UK’s armed drone could be deployed operationally over the UK.

Since 2023, the MoD has refused to disclose details of UK Reaper flights even thought it has done so previously for more than a decade.  It is likely that similar secrecy will surround Protector drone flights and sorties not only if they are deployed overseas but also if deployed within the UK.

New ‘Protector’ armed drones to begin flying in UK – Join the protest on 13 November

 

The UK’s new armed drones – known as  ‘SkyGuardian’ internationally, but renamed ‘Protector’ by the UK –  will begin test flights in the UK next month after the Civil Aviation Authority (CAA) agreed to new airspace rules around RAF Waddington.  The MoD will undertake “a small number of time-critical proving flights” of the new drone ahead of a longer test and training programme due to begin in late 2023/early 2024.

The first of an initial batch of sixteen MQ-9B SkyGuardian was flown into RAF Waddington on-board a transport aircraft on 30 September.

According to Jane’s:

While the Protector fleet will be based at and operated from RAF Waddington, it will spend most of its time overseas in the same manner as the Reaper fleet. A future operational scenario could see the Protector ferry itself from RAF Waddington to a location in the Middle East or Sub-Saharan Africa, arriving in theatre to be met by a team that would arm and prep it for its mission.”

The UK is replacing its fleet of ten Reaper drones with up to 26 of the new ‘Protector’ drones.  The newer drone has further range and longer endurance, as well as being capable of carrying more weapons.  It is also capable of autonomous take-off and landing.

Why we continue to challenge the use of armed drones

As we have argued over the past decade, while remote-controlled drones are presented as enabling ‘pinpoint’ accurate air strikes which enable us to ‘take out’ bad guys without risk to our own forces, the reality is somewhat different. While the UK continues to claim that only one civilian was killed in the thousands of British air and drone strikes in Iraq and Syria, journalists and casualty recording organisations have reported large numbers of civilian casualties from US and UK air strikes.  In addition, as they can be deployed with no or few boots on the ground, making it much easier for political leaders to choose to use armed force.

Armed drones have also enabled a huge increase in so-called ‘targeted killing’ including killing of individuals far from battle zone.  While some argue that it the policy of targeted killing that is problematic, it is hard to deny that the practice has hugely increased with the advent of armed drones. While the US is at the forefront of such operations, the UK too has used its drones to carry out a number of such killings including the killing of a suspected ISIS leader in Syria in December 2022Read more

Latest update shows UK drones spreading across air, land and sea

We’ve updated our directory of current UK aerial drones and drone development programmes and wanted to highlight that, while drones have been mainly the preserve of the Air Force, they are now increasingly being acquired and used by the British Army and the Royal Navy.  Meanwhile, although the MoD is keen to point to the imminent arrival of its new armed drone, which they have dubbed ‘The Protector’, problems lie ahead.

Protector problems ahead

The replacement for the UK’s Reaper drone – dubbed ‘the Protector’ by the UK but called SkyGuardian by the manufacturer (and everyone else really) –  is supposed to be in service by mid-2024.  While the first aircraft from the production line has been delivered to the RAF it remains in the US for on-going testing and training.  However, two significant problems need to be addressed over the next 18 months before these drones become operational.

Firstly, recruitment and retention of personnel to operate the drones has been an on-going problem as Sir Stephen Lovegrove, then MoD permanent secretary, told the Commons public accounts committee in 2020.  This is likely to be even more so now as crews will be based permanently in Lincoln rather than having the option of being deployed to the sunnier climes of Las Vegas, after the UK shut down its US-based drone operations.

The RAF partly overcame recruitment issues by drafting in Royal Australian Air Force (RAAF) pilots.  As the RAAF  was set to purchase SkyGuardian drones it made sense to the RAAF to send pilots to operate UK armed drones as they would then get training and experience of using these systems before their drones arrived in Australia.  However in April 2022, Australia abruptly cancelled its planned purchase of SkyGuardian drones due to budget problems following the setting up of AUKUS alliance and the plan to build new nuclear submarines.  Given this, it seems likely the RAAF will not be so keen to provide personnel for the UK’s drone programme for much longer.

Public consultation on allowing armed drones to fly from RAF Waddington opened – have your say!

Above us only….drones?

The Civil Aviation Authority (CAA) has formally opened a public consultation on the Ministry of Defence (MoD) proposal to change airspace regulations around RAF Waddington to allow armed Protector drones to operate from the base from 2023. In short, these changes will put in place  a ‘danger area’ around Waddington to allow the drones to take-off and land.

Currently the UK’s fleet of armed Reaper drones are not permitted to fly within the UK as they were not built to appropriate standards.  However the MoD argues that its new drone – called SkyGuardian by the manufacturer but labelled ‘Protector’ by the MoD – has been built to stricter construction standards that should allow it to be certified to fly within UK airspace. Separate from the construction issue is the very significant question as to whether large drones (military or otherwise) can fly safely in airspace alongside other aircraft. Drone advocates argue this can be done though using electronic ‘Detect and Avoid’ (DAA) equipment but this is as yet largely untried and untested.

Map of potentially affected area from CAA website

While this consultation is therefore limited in that it is focuses only on specific airspace changes around Waddington rather than wider questions about the safety of opening UK airspace to large drones, we would urge those concerned about these developments to respond via the dedicated webpage.  All members of the public are invited to respond and it should only take a few minutes.  The consultation is open until 30 November.  Read more
