RUSI research fellow Justin Bronk has made the case for replacing the RAF’s Sentinel R.1 fleet with additional P-8A Poseidon aircraft.

Justin Bronk is a Research Fellow specialising in combat airpower and technology in the Military Sciences team at RUSI. He is also Editor of the RUSI Defence Systems online journal.

The Sentinel R1 is an airborne battlefield and ground surveillance aircraft and is interoperable with other allied systems such as JSTARS and the NATO Alliance Ground Surveillance system. In 2010 the UK government’s Strategic Defence and Security Review announced its intention to “withdraw the Sentinel airborne ground surveillance aircraft once it is no longer required to support operations in Afghanistan”.

Sentinel has supported the British Army in Afghanistan and allied efforts in Libya and other locations. This was reversed in the last defence review, which stated:

“Sentinel will be extended in service into the next decade; Shadow until at least 2030; and Sentry and Rivet Joint until 2035.”

Bronk discusses the multiple retirement dates given for the type and why that’s an issue:

“Unfortunately, there have been several negative consequences of the multiple retirement date announcements and postponements for the Sentinel fleet. First and foremost, long-term investment requirements such as training simulator upgrades and base infrastructure components have been difficult to resource due to constantly looming official out-of-service dates.

Sentinel in flight over Iraq.

The aircraft themselves have been upgraded and overhauled as mission tempo and changing real-world missions required, but without a standardised and sustainable structure in place for the Sentinel ecosystem as a whole.”

The P-8 Poseidon, developed by Boeing, is designed to conduct anti-submarine warfare (ASW), anti-surface warfare (ASUW), and shipping interdiction, along with an electronic signals intelligence (ELINT) role. This involves carrying torpedoes, anti-ship missiles and other weapons. The type is also capable of overground surveillance.

Bronk goes on to explain why expanding the P-8 fleet is a good idea within the context of replacing Sentinel.

“It is thus a fair assumption that the RAF’s P-8A Poseidon fleet will find itself heavily utilised, and with only nine aircraft there will be an inherent and inescapable trade-off between the capacity and crew proficiency for the core (and critical) ASW mission set, and other global surveillance and enabler missions. This brings us to the central point.

If the UK can buy its way into the highly capable AAS radar programme, which is not a certainty but there are multiple historical precedents for, then the RAF could replace the remaining Sentinel R.1s one for one with additional P-8As equipped with the AAS pod. This would ensure that the Sentinel’s valuable wide-area surveillance, SAR mapping and GMTI capabilities are not lost during the cuts which are likely as the global economy contracts post coronavirus, when small bespoke fleets of enabler aircraft will be the juiciest targets.”

For a further explanation of the P8 fitted with the Advanced Airborne Sensor (AAS), see the below link. https://www.thedrive.com/the-war-zone/33289/behold-these-awesome-shots-of-a-navy-p-8a-poseidon-carrying-its-big-secretive-radar-pod The US Navy P8s have been testing the AAS since last year. Although they are being tight lipped about its capabilities, the US Navy are very happy with its development. There was one report of the system being used to track drug running boats and semi-sermersible craft in the Gulf of Mexico. The burning question though is it at least on par with Sentinel, if not why bother? From the cyptic answers and reading between the lines, it appears that the… Read more »

Looks like a great capability boost. I wonder if we could have some of our later fleet equipped in their build phase as surely that would cost less than adding it on later, that’s if we even decide to equip ours with this secretive ( prob costly) tech.

The AAS is made by Raytheon. It’s from the same family of radars that the Sentinel radar is from.
The big issue would be what about ground stations, handoff to targets etc. that Sentinel is really good at.

I agree with much of what you wrote apart from using the 737. Let me explain first with the current pandemic many airlines are getting rid of their larger aircraft such as the A380.

Nice idea, but i think we all know what will happen is that they will announce that the capability of the sentinel is now provided by the P8 and that that as the P8 is a better overall platform and can do the job of multiple sentinels, sentinel is no longer needed. Its 101 in the MOD capability cut excuses playbook.

I like this idea. Commonality of types is something everyone on here gets and likes.
But the additional sensor and comms packages that the US and (I think) Australia are bringing in for their P-8As makes this a really smart idea. It would supplement our Wedgetail order nicely, in my view.

Out of interest how much commonality is there between maritime and overland missions regarding operator skills/training for people on the consoles at the back? Is it exactly the same skill set so that someone who has been out hunting subs in the North Atlantic since signing up could transfer over to doing ground surveillance in Afghanistan or wherever the next major land operation happens to be with no extra training or is there some minor/modest/significant retraining needed to adapt from a marine to land environment or vice versa?

Not sure. I worry that the P-8 is a big target to fly over the battlefield. I am not a fan of unmanned, but for this task it might be better to have a stealthy drone.
I think the 9 RAF P-8 need stand off weapons such as LRASM & SLAM-ER.

That’s a good point mate, having this capability on a P-8 gives the platform another string to its bow if you know what I mean, it makes the aircraft an even more dangerous animal in the maritime role. As the P-8 has long range sensors, it could attack enemy naval assets using long range stand off weapons without having to expose itself to likely anti aircraft defence systems.

This plan would make sense to me, assuming there was no dramatic loss of capability. The sentinel, as great as a platform as it appears to be, has been vulnerable for years now and there are good points made about sustainability into the future. More P8s with interchangeable pods will secure the capability and give the P8 fleet some more critical mass. I’m not sure how many P8s are in use at any given time (2 on ops during high intensity periods?), but drawing from a larger pool of P8s has to be more efficient. Could they all be based… Read more »

It makes sense to deploy the aircraft around the British Isles so they can cover a wider area quickly, it would also cut down flying hours meaning less maintenance. If they were all at Kinloss say, it would take about 2 hours to fly to an incident off of the Cornwall coast which would burn fuel before they even got on station. Also, there’s the old “too many eggs in one basket” thing to think of.

The Brits and the Aussies are probably the only countries that the U.S. would even consider giving this advanced capability too. The only capabilities the Brits would lose with this and the P-8 would be some endurance and a lower altitude. But they would be getting a vastly more advanced and capable radar.

I agree with the group, add a batch of additional P8’s to our 9 currently under contract.

Sentinel is a fantastic asset, but like the scrapped Nimrod MR4A, it’s a tiny bespoke fleet.

Modern avionics require regular technology refresh and rhe cost of this can end up being enoumous.

So absolutely buy the bolt on kit for the P8’s and another 4 or 5 airframes.

So we need an extra 8 p8s To cover all the tasks we will need them to do in future according to a report into the numbers. And to also replace sentinel say 6, so an order of 14 extra will be needed, can’t see that happening unfortunately but no surprise there. Atleast we are also getting wedgetails to replace our old awacs fleet so we will have a pretty new fleet. Not sure what will replace rivet joint in future, actually it’ll prob be what ever the USA decides they will replace with.

Probably a handful, I would imagine they procured 5 Sentinels to to keep three available.

Using that logic, they will probably sanction an additional 3, we would be very lucky to get 5.

What’s needed is a fleet of 25, (18 covering all tasks, with 7 maintenance, training etc).

This would allow forward basing of assets, based in Cyprus and the middle East.

In the right numbers, the P8 becomes a real force multiplier.

I think after 2008 austerity was required not due to the level of debt but due to the annual deficit. The U.K. due to its large financial sector was disproportionately affected by the 2008 crash.

And some countries, weren’t affected by 2008 at all, eg Australia.) This crisis by comparison is global crisis and so can be handled differently.

A potential problem of mission creep here.

This sounds like common sense. Adding to a currently running programme will be cheaper than setting up a new one one. Also slows for economies of scale with currently building up P8 and then E7 lines based on the same base aircraft. It will also fit better with the economic issues post Covid-19.
