But having 25 airframes, which cannot fly (control system needed), which carry no sensor, no armament, neither the software to handle them, with no technical support is for what? Of course, because of patent, we can not "modify" it by our own?

Re: Future ASW
One could say the same about F-35 or typhoon, can't operate it without an airbase. Or even a car, no road, no gas / electricity, can't use it. But people still value unit cost, be that £100m or £50k.donald_of_tokyo wrote: ↑11 Nov 2023, 15:01But having 25 airframes, which cannot fly (control system needed), which carry no sensor, no armament, neither the software to handle them, with no technical support is for what?

Re: Future ASW
Very good point, I agree. So, unit cost (actually, in many cases, many people uses "average cost" in place of unit cost) must be carefully handled.
On escorts, initial purchase cost covers a large fraction. Actually, its life cost will be about a double of the purchase cost. Also, what kind of support is included in the "program cost" differs nation to nation, and even project to project. But still, comparing them will give us a good indication of their inherent cost.
On UAV, it is clear that the airframe cost is a minor fraction. I understand that the "airframe cost of MQ-9B" is similar to the "airframe cost of E-7A and/or P-8A". B373 airframe is not that expensive and the E-7A and/or P-8A "unit cost" is dominated by its sensors and analysis systems (and its systems integration). So, I understand saying "£15m airframe cost of MQ-9B is cheap" is nearly equivalent to "B737 airframe cost of E-7".

Having fixed the basics, we should absolutely expand our Protector fleet, purchase another 20 odd systems, with the necessary ground control expansion and have the ability to reconfigure the drone as needed, between baseline Protector, to Sea Guardian and ( if possible) with the wing kit to Mojave Carrier deployable capability.
Have a pool of entirely reconfigurable airframes, we can alter as operational profiles dictate, from RAF long endurance patrol and precision strike, to land based / Carrier deployed ASW and possibly carrier organic AEW??
I would add, to make them and any other large UAV fully ( and safety ) operational on a QE class, a few mods would be needed in my opinion
First, a simple low energy arrestor system ( plus hook for the UAV obviously) and a reconfiguration of the flight deck, bringing in an angled runway, with the necessary extension to port and re ballast.
The moment you reintroduce ' conventional landing ' to a Carrier, even apparently low speed, you bring back the safety element needed by the angled runway.
We invented the angled deck after all and you don't want a heavy out of control UAV running amok straight down the middle of your flight deck if it malfunctions!!
Re: Future ASW
The tail hook addition to a UAV with a large centre line radar pod and pusher prop will be entertaining to see.
UAVs of this size and information gathering capability suck in a lot of manpower. I think a lot of manpower supporting reaper was contractor based and for protector it will be service personnel based hence costs associated with training infrastructure and support services being stood up in the U.K.

Re: Future ASW
Yep, even take off and landing was handled by contractor's on the ground. After take off control was handed to RAF Waddington via satellite, and then handed back to a local team for landing.
Lots of people are needed to operate complex drones like Reaper. On a carrier it'll be almost as difficult as operating F35.
Recently GA have been working to increase automation to streamline operations, which I expect is part of the RAFs protector.

ASW 2040 will be a systems of systems and looking at each facet of the system in isolation perhaps underestimates the true potential of the unmanned technological revolution.
Multiple ASW capable MALE STOL drones operating with a group of armed XLUUV’s could be a real handful for a SSN in the decades to come.

Re: Future ASW
Multistatic sonar is more important for the above application, and AI could help process the huge amount of data multistatic systems collect.
In a multistatic system a T31 could pull a powerful active sonar, essentially illuminating the underwater environment to be picked up by other passive sensors in the network.
AI is not going to make the T31 capable like a T23, but new technologies allow the Navy to approach the problem from different angles.

More than that, why not a RB2 or even even an unmanned Damen FCS 4008 like Patrick Blackett?

The deployment of an ASW system of systems validates to a certain extent the supposed capabilities of the T32.
However the T31 and Enforcer 14428 combo still looks superior as it’s difficult to see how one singleton vessel could achieve so much without creating gaps in its own defence elsewhere.
IMO the most pressing concern is not a T32 style vessel, it’s an armed XLUUV to augment SSN numbers. A XLUUV that can travel huge distances at speed, lay dormant on the seabed for weeks or months or stealthily track other underwater contacts and ultimately neutralise them if required. A XLUUV capable of operating alone, as a group or with the SSN/SSBN’s. This really should be an extension of AUKUS and would provide additional mass even before the next-gen SSN’s commission.
The ultimate result should be a next-gen ASW system of systems which is securely networked to give complete situational awareness of the sub surface domain.

Why would a xluuv need to travel huge distances at speed? Unless you mean flown by air transport. In my mind a xluuv needs to operate in the deployment sense like the submarine rescue sub. Can be deployed from any ship with a dock or a frame and predominantly then operates at choke point locations.

Re: Future ASW
Where could AI make a difference to ASW?
I think the answer to that lies in the fact that we aren't actually seeing anything that exhibits genuine AI yet. What we see today really falls under the mantle of Machine Learning, which itself is just advanced pattern recognition, using massive libraries of data.
As I understand it, ASW lies in an operators ability to recognise certain patterns, after adjusting/ allowing for a very large number of variables (heading, velocity, salinity, depth, temperature etc) as representing a contact. Current "AI" is based on doing exactly that sort of task, winnowing out all the stuff that is irrelevant to the task and identifying and ranking those combinations that match up to a specific course of action.
Current computer systems do that to a certain extent, but their coding depends on the programmer already knowing what patterns to look for. The power of AI lies in it's ability to identify patterns that have not yet been recognised as valid.
I'm explaining it poorly, but I hope you get the idea

This can be done right now without AI.

In general, submarines can travel huge distances slowly, or short distances fast. Only SSNs can do both at the same time, which is out of scope for XLUUV

In general, submarines can travel huge distances slowly, or short distances fast. Only SSNs can do both at the same time, which is out of scope for XLUUV
IMO the XLUUV’s will split into two distinct groups.
The first will be around 15m to 25m operated directly from suitable vessels such as the Amphibs and multi role vessels. Transit speeds and endurance will be provided by the host vessel.
The second will be much larger, perhaps up to 50m with a surfaced displacement of around 1500t. These XLUUV will be independent of other vessels with a mix of lithium batteries and AIP propulsion. The range could be up to 6000nm to 8000nm with a top speed submerged of 20kts and an endurance of around 6 months. Similar to SSK performance but with increased endurance. The armament could range from torpedos to VLS cells. All for a fraction of the cost of a SSN.
The UK needs to get to the forefront of this revolution asap.

What you ask for in your second request hasn’t been achieved on land, on the sea or in the air so I’m think it’s wildy optimistic that it will happened underwater where challenges particularly in communication are more difficult.
