Project Cetus will deliver the largest and most complex crewless submarine operated by a European Navy, say the Ministry of Defence.

The contract award is worth £15.4m.

The vehicle will have a modular payload bay that can be extended by adding another section, doubling the capacity.

“Project Cetus – named after a mythological sea monster – enhances the Royal Navy’s experimentation with autonomous underwater systems. It is the first step in developing an operational autonomous submarine that will work side-by-side with crewed submarines – including the Astute-class hunter-killers and their successors – or independently.

Its maximum operational depth will exceed that of the current submarine fleet, meaning Cetus will equip the Royal Navy with even greater reach into the oceans in support of UK defence. It will be able to cover up to 1,000 miles in a single mission.

Cetus will be 12 metres long – the length of a double decker bus – 2.2 metres in diameter and weigh 17 tonnes. It will be the largest and most complex crewless submersible operated by a European navy. The bespoke vessel is being designed and built for the Royal Navy by Plymouth-based tech firm MSubs. This contract will create 10 and support 70 specialist jobs in the city.”

More specifics of the intended design come from a job listing for a Design Engineer for the project posted earlier this year, which stated:

“Primary role is to lead project CETUS; the design and build of a 27 tonne, 12m Autonomous Underwater Vehicle (AUV) Demonstrator, with specific responsibility for leading on the establishing technical specification and deliverables, running the competition, evaluating tenders and contract placement during FY21/22. Subsequently responsible to ensure requirements and delivery pace are being met and are accepted.

Secondary role is to lead on technical studies exploring AUV concepts and provision of advice to the application of AUV to the future underwater battlespace including those AUV that could complement the replacement Astute Class SSN.”

The vessel will be delivered to the Navy in two years’ time and will “further advance the UK’s ability to protect our critical national infrastructure and monitor sub-sea activity”.

Very interesting…good size…hopefully a project that will bear fruit. Looks like a large cruise missile. Was expecting a round tube, but possibly the sub is pressurised to assist in keeping things together at depth.
I would assume that this is not news to Msubs, and they have been working on something like this for ages.

The pressure hull may be cylindrical and the free flooding parts outside of that are squared off to maximise volume while still fitting inside a standard 2TEU shipping container.

If it’s unmanned does it strictly need a pressure hull? Electrical systems need to be waterproof, but machines can generally be built to handle pressure.

By pressurising you add strength to the structure. Being unmanned, the pressure can be raised above that of a manned submarine which may go some way to explaing how Cetus can dive deeper.

So they say it will be autonomous, I wonder how many will get stuck or confused when out of contact, but how will it receive commands? Float a communications pod on a cable up?

Of all the plans that depend on not yet existing autonomy this seems very optimistic: It has to navigate a complex landscape we don’t fully understand while likely unable to receive commands.

I assume that element will be part of the testing and experimentation. It’s logical to assume it has an autonomous mode whereby it can navigate independently and safely using sensors and programmed to pop up and receive new commands. I saw it more like how they programme the Mars Rover to do things rather than under constant control, say like Reaper.

I get that, if they’re smart, they’ll try and keep it simple: stay well away from any surface, no trench or cave exploration.

However considering we have trouble making ai navigate consistent constructed environments like a road, even with a human behind the wheel, I have my doubts.
It’s very likely to encounter a situation it hasn’t been trained for, or end up somewhere it can’t navigate.

Agree 100%
• The sea is probably the easiest environment on earth for AI to navigate
• The ethical/ legal issues of allowing machines to kill humans will be the greatest impediment to deploying this ability in the future: as can be seen from the debate around the legal responsibilities of self-driving cars. We have had such machines in the past, eg land-mines, but the West has felt the moral need to phase these out. Sadly the totalitarian regimes that oppose us, Russia, China, etc will have no ethical issues around deploying autonomous killing machines.

That’s one level of understanding. You could say, that it can tell the differences between large armoured vehicles and smaller unarmoured ones, ie compare an IFV to a pickup.

The millimetric radar allows it form a very good image of a target. That the recognition software analyzes to see if it’s a valid target or not. That was used in the Block 1 version. It was designed as a battlefield weapon where it could then prioritize heavy armoured vehicles over lighter ones.

The AI software has come on a long way since then.

Ah. Some autonomous systems, such as DIVE-LD, can do missions that way, launching from harbour, so for a test vehicle it didn’t seem all that outlandish. As others have said, it sounds harder to work from harbour than a mothership anyway.

Chasing after one of these new breed sounds even tricker than a PAP ROV, given they can go 1000 miles, stealthily, and deeper than a nuclear submarine. If this screws up it may never be found, or found as some museum piece in 70 years time.

In May 2022 the Royal Australian Navy entered into a $140m contract with Arundil to co-fund the design and local manufacture in Sydney of extra large autonomous undersea vehicles (XL-AUV). The first of three 30 metre-long XL-AUVs will be ready by 2023.

The Anduril XL-AUV design is modular, customisable and can be optimised with a variety of payloads for a wide range of military missions including intelligence gathering, surveillance, reconnaissance, targeting and weapons delivery.

Australian company C2 Robotics is also developing an 8m uncrewed autonomous underwater vehicle called the “Speartooth” with a prototype currently being trialled by the RAN.

It’s a test boat for underwater autonomy, with the ability to carry/deploy various payloads. Can it operate out of sight and out of mind? And the military loves its man-machine teaming exercises.

The article states:

“It will be able to cover up to 1,000 miles in a single mission.”

A 1000 miles equals 1600km or approx 870nm. Is that range? Or radius?

Whatever it is, it’s not very far.

As a comparison the Boeing Echo Voyager is reported to have a range of 6500nm (12,000km):

I was just reading the Voyager link (thanks for that). 6,500 NM is a maximum range with a fuel payload module. Being diesel-electric it can only go underwater a certain distance (150 NM) before it has to surface to recharge. Cetus will be able to travel underwater the full distance, which can be extended by adding more batteries. I think that makes it inherently more stealthy. Given improving battery technology, this might be the final configuration. I reckon Voyager and the Orca test vehicle are the right comparisons, not the forthcoming Orca prototypes.

Mentioned a couple times my own ideas for a somewhat simpler sub surface drone and considered the feasibility of effectively closing down for periods and being reactivated and how that might work but if if could ‘sleep’ for days then it could be a lethal weapon awaiting a victim to come along but perhaps complex to actually achieve at the highest ideal autonomous levels maybe but not for lesser applications perhaps, especially if you can contact it to reactivate when other assets inform you as and when it is needed.

Hi Spyinthesky,

What you have described is sounds very much like some decription of modern smart mines that I have read about in the past, at least in terms of deactivation, reactivation type operations. As such I would suggest it is an eminately possible and sensible proposition.

39ft compared to 51ft, horses for courses I guess but surely this is a test vehicle, by the time a production vehicle goes into production, propulsion, battery and overall size could all be changed to improve that range if felt necessary, I would presume testing will determine the optimum compromise.

The pictures on the NavyLookout article are very good. One thing I noted was that the battery packs looked rather small, if I had understood the CGI pictures correctly so plenty of room to increase capacity. Of course, if you increase battery capacity you either need to increase the available bouyancy (pressure tanks?) or reduce the payload.

I recon the range is limited inpart because is it a test vehicle and the 3 year test programme does not require huge ranges i.e. designed to do a limited job.

I think some of the size requirements come from the ability to house it a full size iso container. Thereby making it more easily transportable.

Here in Oz we have a similar project underway, with a value of approx A$140m:

“operational XL-AUVs produced at significant scale and in service within five years.”

That’s impressive.

The RAN has a couple of significant future budget allocations in the coming years (of many billions of dollars), for a variety of undersea systems.

With the size of Oz, and our areas of interest, UUVs and AUVs will play a significant role in the years ahead.

If they are using it to keep an eye on under-sea infrastructure (cables and pipelines) a 1000 miles should be more than sufficient, and it just needs to transit from one “friendly” country to another

Hi Mark,

I suspect that it is designed to carry out a specific set of trials and they have set the range requirements accordingly. At £15m it is quite a cheap craft compared to the numbers being quoted for the US and Australian programmes.

We clearly have some catching up to do.

Would anticipate a comprehensive roadmap for the development of a class of a commonly designed, autonomous underseas vehicles, as a subset of AUKUS master plan, to be released in March 2023. The unclassified, redacted version for public release could be a rather slim volume.

Hi all… I know nothing about submarines. However, I do not currently see what purpose a 12-metre autonomous ‘tube’ would serve the Royal Navy. A decoy maybe for a Trident sub?

I was formally a BSFO working in the Clyde basin. As part of my job I was involved in the Perisher excercise that pulled a trawler down killing 4 fishermen. I have also dealt with waste from nuclear submarines. which is a threat to life. I have also dealt with torpedos that have gone awry.

This idea, which is no more than a glorified torpedo, will cause a hazard to shipping and the lives of fishermen and should not be deployed within coastal waters.

Excellent news it’s what we’ve been calling out for years and for that price I hope we are able to get several dozens of them, as the premier navy in the Euro Atlantic we need to be able to lock off the russian navy for good.

“The vessel will be delivered to the Navy in two years’ time”.

Is that real? Design AND build AND deliver in only two years? Can’t imagine that, unless I’ve mis-read something.

I think MSubs did it even faster with Manta. According to their website (did a quick search mid-typing) outline design to delivery took them 14 months. Cetus is bigger than Manta, but I don’t think two years is all that unrealistic. Underwater test boats don’t have quite the same strictures as military submarines.

I would like to think that Msubs have had something like this in the top draw for a while. Making it to fit a 40’ container is a good idea. All the necessary support stuff can be in the same container and presumably will then fit in a mission bay. Makes for easy, and covert transportation (obv can’t hide the actual container, but the contents would be secret). With regards to the ‘only’ 1000 mile range, it seems to me that a more easily achievable goal would be having a slightly less advanced (read..expensive and time consuming) operating system tuned… Read more »

Hi Crabfat,

I would also point out it is a trials vessel not an operational platform, so different design standards would like apply e.g. it could be that there is no intention to carry or fire live weapons.

Sounds like a big brother of the torpedo sizes autonomous and self-redoch thing the USA is playing with.

if this unmanned sub detects something interesting, how does it report back without giving its position away and would we allow the artificial intelligence to take an action which may have significant consequence.

interesting design, nice to see that it is being produced in the southwest to give us a much needed bit of attention down here BUT…the article itself…early on it is stated that the sub will weigh 17 tonnes but then later on it says 27 tonnes…where did the extra 10 tonnes come from…presumably the additional payload bay?
