The United Kingdom has announced that it intends to place an order for the Certifiable Predator B as part of its Protector MALE UAV programme.

General Atomics modified the Reaper platform into the certifiable Predator B in order to make it compliant with European flight regulations to get more sales by European countries. In order to fly over national airspace, the aircraft meets airworthiness requirements with lightning protection, different composite materials, and sense and avoid technology.

According to the 2015 Strategic Defence and Security Review, the Royal Air Force will operate at least 20 Protector systems by 2025, replacing all of its current 10 MQ-9 Reapers.

According to a justification for a ‘sole-source award notification’ published on the 24th of April, the MoD has given General Atomics a GBP415 million (USD605 million) contract for the UAV. While the award did not disclose numbers, the UK government has previously said 20 will be procured.

According to the MoD:

“The Unmanned Air Systems Team of the UK Ministry of Defence intends to acquire the Protector unmanned aerial system through a government-government Foreign Military Sales contract with the US Department of Defense (DoD). The MoD has conducted a thorough Assessment Phase that has concluded that the CPB is the only system capable of achieving UK Military Type Certification and delivering the Protector requirement within the required timescales. The only means of acquiring the CPB is through a contract with the US DoD”

In February, General Atomics announced that theย long-endurance Predator B, which will eventually increase the flight time of the Reaper from 27h to 40h, had carried out its first flight. The aircraft is also expected to have a much greater payload than Reaper.

According to company literature, the platform has the following features/benefits:

  • Compliant with NATO flight certification and other standards
    • STANAG 4671/UK DEFSTAN 00-970
    • DO-254A, DO-160B, DO-178C
  • Remotely piloted or automatic
  • Automatic takeoff and landing capability
  • Anti-lock Braking System (ABS)
  • Triple-redundant avionics/dual redundant flight controls
  • De-ice, lightning protection, fire detection systems
  • MIL-STD-1760 Stores Management System
  • 9 external stores stations
  • C-Band line-of-sight data link
  • Ku-Band SATCOM data link
  • Provisions for DRR retrofit kit
  • Certifiable GCS
    • DO-254 compliant multi-core computer
    • DO-178 flight control software
    • Certified displays and full payload separation

A sensible decision. A clean off-the-shelf purchase of some good kit that shouldn’t suffer the endless design tweaks, increasing project costs and ultimate scaling back of numbers that we’ve seen in MoD RN projects recently.

What’s happening with taranes?

Dave B Philips

The Taranis has been incorporated into the Future Combat Air System (FCAS) programme working along side France, Which was always the aim of this programme… Its likely to be based off the Taranis air frame that has already been seen, with technology from UK and French defence companies.


BAE were down in Woomera in the winter testing it again. The research will go into a joint Anglo-French UCAV design that will take elements of both Teranis and nEUROn.

Taranis was an experimental platform looking towards a future unmanned Typhoon type capability.

So is it happening it or what cause it doesn’t look like a typhoon

Harry Eaton

“Typhoon type capability” does not necessarily mean it’ll look like a typhoon Saul, it was a platform to test the viability of many systems.

Paul S. Davis

Isn’t the current Reaper a variant of the GA Predator B anyway? Essentially we’re buying more of an updated version of what we’ve already got. Could the current fleet therefore be upgraded? This would reduce the number of brand new airframes needing to be purchased.

Dave B Philips

Not really. There are structural airframe differences which are critical to its longer range design. Upgrading the Reapers we have now would likely be very uneconomical and wasteful. Also, consider that we only have 10. Upgrading would also mean we lose airframes and therefore capability.

It makes sense and is almost certainly more cost effective to purchase the new design and contract dependent, sell the current fleet we have…


Even if it was possible (and all that Dave says is correct) the current ones have also been worked very hard. I think there are a lot of hours on the airframes which adds to the uneconomical argument.


Will they come with brimstone integrated?

Andrew Casson

As cheaper replacement ?


No. More expensive, or at least more capable (maybe economies of scale and more mature manufacturing processes have reduced costs, I don’t know but I doubt it).

The new B versions, apart from the technical niceties of meeting European flight regs, also have much longer endurance, two extra hardpoints for weapons, and can carry a heavier payload. And twice as many of them to boot. For once this is a significant uplift on current capability; better kit without a reduction in numbers.

David Southern

“in order to make it compliant with European flight regulations to get more sales by European countries”. Doesn’t that mean EASA Type Certification then? Rather than military Type? And what is the airframe cycle life of these things? I suspect their more likely to exceed their flight hours than cycles?


There is something missing from this announcement, where is the involvement of BAe to apply custom UK features resulting in twice the price and resulting in the numbers ordered being halved.

Are they actually going to do the sensible thing and buy an off the shelf part!


Ssshhhh…. Don’t jinx this ๐Ÿ˜‰

David Steeper

I have a good rule of thumb with all UK defence contracts. If it goes to Bae panic if it goes to anyone else breath a huge sigh of relief.

Max Chris Hedges Bingham

An off the shelf purchase?
This the second after the P8 Poseidon decision….

What next? Type 31………
