The Royal Navy say their British ships led the way in “game-changing” NATO autonomous exercises off the coast of Portugal.

Frigate HMS Lancaster and minehunter HMS Hurworth tested the use of uncrewed tech – from drones to underwater survey vessels, which could be used by NATO on the front line of operations in the future.

“For the month-long trials, more than 11 warships, 120 autonomous vehicles and 1,500 military and civilian personnel from 15 NATO countries took over the waters near the Troia Peninsula, Portugal. This is the first time the Royal Navy has sent ships to the exercise, with previous participation involving crewless boats and drones. It’s enhanced presence in the exercise, hosted by the Portuguese Navy, comes as this year marks the 650th anniversary of the Treaty of Tagilde between England and Portugal – the oldest alliance in the world.

HMS Lancaster played a key role by serving as the command hub for the multitude of autonomous systems, feeding information to the other ships in the task force to allow them to make crucial decisions during the numerous scenarios. This allowed the task group to see and utilise the range of drones, underwater vehicles and vessels.”

Jim Beaton, the Royal Navy and UK lead for the exercise, said:

“REPMUS 22 has been a game-changer, first through the trial of an autonomous asset ready combat system in HMS Lancaster, from where we were able to distribute an autonomous system operating picture to a NATO task group. This is a huge advancement, and we have taken that forward to support two NATO Standing Naval Forces. Dynamic Messenger saw us take autonomy to sea in a NATO context. Additionally, we have been able to bring some of the navy’s newest operators to the exercise, getting their feedback on the system and starting to push that experience back into the fleet.”

What was tested?

First up was REPMUS – a testing ground designed to allow large-scale experiments for NATO navies and their industry partners. During this period the ships and crewless technology were put to the test through a range of scenarios above, on and below the water.

“Exercise Dynamic Messenger followed, where the tried and tested uncrewed systems were integrated into operations both at sea and ashore. This was the first exercise under NATO command to use autonomous underwater systems, testing readiness across a variety of challenges including submarine threats and sea mines.

HMS Lancaster carried out trials with Puma, an Uncrewed Air Vehicle primarily used for surveillance. The battery-powered, hand-launched UAV is designed to cope with challenging environments across the globe, and is predominantly used for intelligence gathering.”

Soucy have said their tracks are good up to 45t. They were first trialled on M113s. Which is not that much heavier than CVR(T).

The reports were that it drastically reduced crew fatigue, you could have a conversation in the back without shouting or needing headsets. It gave a much smoother ride and also helped with fuel consumption. One CV90 did have its band track destroyed by a controlled IED. This was repaired by the crew, who had the option of a splice repair or replacing the whole… Read more »

Steel tracks are one of the noisier elements of a moving tracked vehicle. Even with rubber pad inserts, which are really there to protect roads. The flexing, constantly moving hinges and resonance of a steel track not only causes noise, but also vibration. This is a bit like on a train where you hear and feel the train traveling over the welds in the track. As each wheel passes over the hinge joint it causes a jolt which is transferred through the suspension to the hull. Which is then felt by the crew. This can be reduced significantly by using… Read more »

I’m sure 19th century admirals would have looked at ship’s accommodation for modern ratings and declared it a total waste (once they got over the whole women thing) and asked why wasn’t the money being spent on more guns. Yet for all we carp on this forum about FFBNW, I’ve never heard anyone propose sailors go back to time-sharing their hammocks to pay for Mk41 silos. If the Government ever stops cutting army numbers and retention becomes a bigger thing, it’s possible delivering tank and recon crews or infantry in the best shape to fight might get a priority bump.

Didn’t they show images of the T-650 fitted with a Stingray. I wonder if they’ve done any drop tests yet. Would be a force multiplier when teamed up with a Merlin and T23.

Indeed though it’s the triple Brimstone fitting that really interests me. I wonder if a similar Martlet fit out might be useful at sea for some of the roles that the Wildcat would be expected to undertake ie getting eyes, assessing threat and being able to nullify it, especially in adding breath to that capability that a Frigate could seriously exploit maybe prove vital in some hostile environments.

I don’t see why not. Designating the target would probably be done from the ship or by the Wildcat. It definitely would add a force multiplication factor to proceedings. The obvious situation being in the Gulf, where the Wildcat is flying recce or checking out a ship, without Martlet fitted, then using the drone as a weapons carrier when needed. Another scenario is where the Wildcat needs to carry a boarding team. You can use the drone as an additional offensive/defensive layer for overwatch or close air support. The other option is if it can carry a pair of Stingray.… Read more »

You have hit the nail on the head. Expensive is not needed. If there was ever an example needed I present watchkeeper. Over priced and out of date rapidly.
In my view the developments need to be in power management, and plug in systems/payloads.
That way the actual flying bit can be modified, replaced rapidly as better drones emerge.
So all the drones have the same connectors, management systems, pylons etc. that way industry can easily make attachments that can be taken on and off as required.

Sorry to butt in. But a tilt-rotor is significantly more complicated that a helicopter. When in the helicopter mode, the tilt-rotor still makes use of a swash plate that changes the disc angle. The range of movement is not as much as the helicopter’s. But think of the mechanics needed to lock and unlock the swash plate when transitioning to and from forward flight. However, the tilt-rotor is significantly more efficient in forward flight than a helicopter. Hence the Valor’s longer ranger and much higher cruise speed. The Defiant has some key advantages for Army use. It is much nimbler… Read more »

Sorry to disagree DB, but the Defiant is a complex beast and “experts” in the helicopter business have stated this, including Bell who looked at this option, a double bladed helicopter with pusher prop. The purported advantages are wishful thinking I’m afraid. The Valor is a 3rd gen tilt design with much simplified layout. The non-tilting engine is a major simplification to a design which has been flying for 20 years. So no, logic does not suggest that a 3 prop design is “simpler” than a fixed wing tilt shaft design.

Right, I never said that the Defiant was not complex. Compared to a standard helicopter it is in a different league.   Let’s be honest the Defiant uses brute force to overcome the traditional disadvantages of a helicopter. These are blade stall and unbalanced leading blade lift.   As a traditional helicopter flies faster, even though the rotor rpm stays the same, the local airspeed over and around the tips, increases faster than that over the main body of the helicopter. The first problem it will come to is an unbalanced lift component. Where the leading blade generates more lift,… Read more »

A very fulsome analysis. I think the takeaway is that both are complex compared to existing solutions, but one has had more opportunity for testing and evolution. The Blackhawk is an old design and I’m sure both solutions will be orders of magnitude better. I note that the decision has been delayed again. I suppose one solution would be to split the initial order 50/50 and see who wins out on in-service performance.In view of the size of the overall requirement.

You’re welcome, mate. Of the two, I would say the Defiant is slightly more in tune with the US (Green) Army’s needs to replace the Blackhawk. However, the Valor can give the Army something they haven’t had before, which is long range (fast) insertion. As at the moment they have two options, either using C130s for a tactical air drop or using Chinooks. With the C130 air drop, you can guarantee at least 5% of those jumping out of the plane will have some form of landing injury. Plus, any heavy equipment will need to be thoroughly prepared prior to… Read more »

The Osprey is a 2nd gen aircraft and quite complex, the Valor is a 3rd gen aircraft design to be cheaper to maintain and to be less complex to fly. Now as to metrics, yes it flies faster and further. It has better fuel consumption and cost per flight hour. Yes it can fly higher and better in hot conditions. But other than that, they are pretty much equal.

I would not compare the V22 to the Chinook. The V22 was designed to replace the USMC CH46 Sea Knight. This is a smaller version of the Chinook if you will. The V22s design is heavily compromised due to the restriction placed on it operating from the Wasp class LHD. It had to be capable of taxing past the island, with the nacelles in the vertical position. With at least 5ft of clearance between any of the ship’s structure and the prop-rotor tips. This meant the prop-rotor blades are shorter than ideal. Which then means they have a higher nominal… Read more »

IMO the issue with drones for Recce is staying power. Much like helicopters in the attack role, you can put a drone up to correct fire, or do an aerial recce, but eventually the thing will have to come back.

Foot and armoured recce on the other hand has the advantage that once you set an OP you can keep it there for literally days, continuously, noting everything that comes and goes.

That is a good point. So maybe 21 and 23 will go back to their stay behind roles, or a variant of if not actually staying behind a moving front. Perhaps 4/73 and the HAC need augmenting if more money is going on ISTAR, as the DS said.

On the other hand, perhaps too much duplication?

The Transwing technology looks interesting, even cool, but will it scale? At the current size it’s no more use than Puma or Sky Mantis, which the Navy currently have, and at least the latter is built in the UK. Transwing would need to be able to deliver OTH radar information back to the ship for longer and for less money than Camcopter to be the future in its class: so a payload of at least 15-20kg, against Camcopter’s 50kg. For USN light VertRep, it would probably need a payload of 25kg+, but the RN is just going for the heavy… Read more »

Next, I would like to see the Seacraft Victa and Kraken K50 when they are done at these exercises in the future.

Just checked out the Victa, pretty much the exact vehicle I envisaged in a few other threads here, having seen what’s happening in the Black Sea, though I was thinking purely autonomous but that offers its own series of problems used at distance so may be more distant a prospect to be useful militarily. Meanwhile a manned solution at least offers some of that potential earlier and a few others too specific to having humans on board.

I guess it would be more for special forces insertion. I think I did see somewhere about the Royal Navy looking for autonomous function and this was still suggested as an option because it covers the functions. I don’t see why they can’t partner up with another company to make an autonomous version. I have also just noticed that it looks like Stingray (TV show) without the large prop at the back.

Yes you are right, having seen a different pic now I remember reading about this project earlier in the year. Sounds quite impressive but some way from what I was envisaging but still some overlap no doubt and all a learning curve.

This is similar in concept but also has potential as an autonomous design I think.

Not very transportable friendly. Their product designs look like they are done because someone thought they looked cool.

Not too bad. There’s a picture of it on the back of a trailer with the wings folding upwards.

Hi, to shed a little light a few of the OT comments about AJAX below: Yes User Validation Trials have started. At about 1:50 the ARES is at full chat (42mph) for the benefit of the viewer, lovely! “Rubber” band tracks? Well, trialled on WR so may make an appearance?? Coping with the All-Weather Track at Bovvy? Smooth as a baby’s bum, comments on the “outdated” torsion bar suspension Mr Wait? All the “bustles” are to carry the MOD mandated CES and C Supps that will be needed. Paul P…. the perceived N & V issues have been addressed and… Read more »

Thx for the bustle info, though ‘CES’ always meant the Consumer Electronics Show to me but that would be a little cramped in there I suspect despite their prominence.

Hi Mr Spy, stands for “Complete Equipment Schedule”, all the tools, tents, cooking stuff, ropes, hammers etc, you get the drift.👍

It’s good that we a testing this equipment out but has any one asked the question how would we use it or get it to real locations in real time to be of use. Can they be launched from a T23 or T45 or for that matter a T26 or T31. We did miss a trick in not having a stern ramp in the T31or T26. Yes I know the T26 has a stern ramp for operating either a RIB, USV or towed array. As these ships will be the primary ASW vessels of the RN then its a towed… Read more »

Impressive indeed; the more so if one Wildcat with fairly short range missiles can take out a swarm of fast attack craft without being shot down. I thought Martlets had to be ‘single threaded’…one at once.

I’m not sure why they have to be single threaded, but even if you are firing at a rate of one every 10 seconds as the craft come into 5-mile range, it’s still pretty impressive.

Smaller missile-carrying FAC often only have anti ship missiles, and even if they carry MANPADs, the Wildcat would be firing with height and distance advantage. If the opposition are big enough to be carrying real SAMs, you’d be reaching for Sea Venom anyway.

Yes, indeed. Wiki quotes Martlet velocity as mach 2, roughly 1500mph and having a SACLOS guidance system; so I think that means the operator would have to keep a target 5 miles aways ‘in his sights’ for 12 seconds. Stinger has a maximum range of about 3 miles I think. At 30mph a FAC would take 240 seconds to close the range from 5 to 3 miles. In 240 seconds you could loose 20 missiles each of which could hit its target in under 12 seconds. A well thought out weapons platform 🙂
