Project 02690 class floating crane SPK-54150 returns to Snake Island

According to satellite imagery made available by Planet, Project 02690 class floating crane SPK-54150 – based at Sevastopol for the Russian Black Sea Fleet – has returned to Snake Island on, or before, 15 May 2022.

Low resolution imagery from Planet shows Project 02690 class floating crane at Snake Island Harbour on 15 May 2022

The whereabouts of SPK-54150 between today and when it departed the area on 12 May 2022 is unknown, but imagery from Sentinel dated 14 May 2022 shows it returning to the island.

Located at 45.224993 30.744780, the shape, colour and size of the floating crane can be clearly seen. The wake behind also shows the very slow speed it is travelling at – the class averages a speed of 6 knots generally.

Collected at 0857z, the floating crane is approximately 42 kilometres away from Snake Island – or 23 nautical miles.

Based on the average speed of 6 knots, it is actually more likely that SPK-54150 arrived around 1230z on the 14th. Obviously, this if it went direct from the spot located. Imagery is not available of Snake Island on 14 May 2022 later than this as far as I’m aware.

The resolution of the imagery available to me doesn’t show whether the floating crane has any cargo. No doubt further high resolution imagery will appear soon.

Snake Island – further activity

**Updated**

Despite heavy losses at Snake Island, Russian forces continue to operate at the island.

Imagery made available by Maxar shows a Project 02690 class floating crane operating at the island’s harbour – along with a Project 11770 Serna class landing craft.

Maxar imagery showing Project 02690 class floating crane operating at Snake Island harbour. The wreck of the Project 11770 Serna class landing craft can be clearly seen, still carrying its cargo. A further Serna class is at the landing slipway, with its ramp lowered.

The theory on social media is that the floating crane is there to recover the sunk Serna class landing craft. This is probably unlikely as in theory the weight of the ship and its cargo (likely one of the 9K331M Tor-M2 family of SAM systems) combined with the sea would take the lifting weight outside of that capable by the crane – **See below for update**

Two options are more likely. Either to recover the 9K331M Tor-M2; or to be used to transfer cargo from other ships to – or from – the island.

It is a risky operation. The floating cranes are not very maneuverable or fast. Their average speed is 6 kts.

Further imagery of the area shows another Serna class operating close to the island. Some thought “clouds” near the ship were smoke trails from Ukrainian missiles attacking the ship. This isn’t the case and it is possible the ship is dispensing smoke to try and cover/protect the operations taking place at the island.

This is clearly failing.

Getting back to the crane and the image of it operating off the harbour jetty.

There is a possibly a 9K331M Tor-M2 is on the deck. More of these have been located on the island so it does appear the crane has either assisted in, or transported, these. How long they last is another question?

Through analysis of satellite imagery from Capella Space and Sentinel, and in conjunction with historic AIS data from FleetMon, it is likely the floating crane is SPK-54150.

Capella SAR imagery dated 11 May 2022 shows a floating crane in the Pivdenna Bay area of Sevastopol.

A colour, low resolution image from sentinel for the same day shows the floating crane – the yellow colour of the crane is clearly visible.

A search of AIS data in FleetMon for the two known floating cranes operating for the Black Sea Fleet – SPK-54150 and SPK-46150 – produced an outcome for both.

SPK-54150 was last “heard” on 10 May 2022 tracking Northwest at 6 kts, not far from Karadzhyns’ka bay. I have access to S-AIS from FleetMon so this last heard means the ship switched off its AIS at this time – the data list confirms it was transmitting via Satellite.

Data from FleetMon shows SPK-54150 was using S-AIS from the symbol at the end of each line

On the other hand, the AIS for SPK-46150 was last heard on 26 March 2022. It does appear to have stayed here since then – or been operational but not used its AIS and returned to the same spot each time.

From this data then, we can conclude the floating crane is likely to be SPK-54150.

As previously mentioned, the use of the floating cranes shows a certain desperation with the Russian forces to maintain a presence on Snake Island.

It really does appear they want to stay there, no matter the risks and potential costs.

**Update**

Eventually, the floating crane did recover the Serna class from the harbour. A pretty good job too as this – as I stated above – would have been at the edges of the cranes capabilities. Not known is wether it recovered the “cargo” first.

The Snake Island attacks – Part Two

In my last blog, I tried to highlight the issues with analysing imagery and videos with only half a story.

I also tried to draw the attention to how fake videos can make one look at others with a lot of doubt as to whether they are real or not.

I concluded that more evidence was needed – in particular high resolution imagery from Maxar or Planet.

The good news is, that not long after the blog was posted, I was anonymously sent an image dated 7th May 2022 taken from either Maxar or Planet – the source didn’t say.

This clearly showed the wreck of the Project 11770 Serna class landing craft in the Snake Island harbour. It also showed the concrete blocks I wanted to see. This was useful as had the image been collected from before the attack, and there been no wreck, then at least the location was pretty much confirmed.

Even the blocks would have been enough then to conclude that the video was legitimate.

It wasn’t long after I received the image that it was published by AP, and shown on Twitter.

For those that don’t have Twitter access – Jon’s account is locked – here’s the image.

I also received a notification from a friend, Scott Tilley – well worth following on Twitter if you don’t. His satellite tracking capabilities and knowledge is fantastic.

His notification pointed me to a website that contained photographs of Snake Island – some of which depicted the concrete blocks used as the sea defences. A great find – and one that had slipped through my rushed searches.

So, hopefully this shows how information can take it’s time to get through to carry out a full analysis.

There’s reasons why the Intelligence services take their time over gathering data on incidents such as this.

Now, as further videos are coming through thick and fast of attacks on Snake Island, more confidence can be had over their legitimacy.

The wingman in this attack is probably very lucky not to have been taken out by the explosion created by the flight leader.

One has to question why the Russian forces are intent in staying at Snake Island. Their losses, I’d say, are greater than those taken by Ukraine.

My friend Capt(N) provided some information on the island in a recent Twitter thread. I’ve taken screenshots here as, again, not everyone uses Twitter.

The thread can be read here.

The Snake Island attacks – Part One

Whilst there is no doubt there have been several attacks on Russian equipment on Snake Island, in the last few days, some dubious video footage has been “leaked” on Twitter showing Russian ships under attack.

These videos do put into question those that do appear to be genuine.

For example, yesterdays – 6/5/22 – “news” that Project 11356M Admiral Grigorovich class FFGH Admiral Makarov was struck by multiple Neptune missiles immediately reminded me of the same claim against Project 22160 Corvette Vasily Bykov at the beginning of March, be it with MLRS weapons rather than the Neptune missiles.

I personally wasn’t convinced about the Makarov attack, and once further ridiculous Tweets materialised using ADSB data from FlightRadar24 (FR24) showing NATO aircraft “monitoring the situation” as proof that “something was going on” – well, I definitely didn’t believe it.

This is just poor “analysis” by people who haven’t got a clue what they’re talking about and should just not bother saying anything. Two examples below.

Unfortunately, the Ukraine war has brought out a substantial number of idiots that are suddenly “experts” in warfare, aircraft tracking, ship tracking and satellite imagery analysis. In reality, they are just plain fools.

And as Ben Kenobi says in Star Wars – “Who’s the more foolish? The fool or the fool that follows him?”

This is the problem with social media. These people have a “show” that they’re experts, and then they get thousands of followers that believe everything they come up with.

Personally, I don’t trust anyone with OSINT in the username.

This idiocy was highlighted when a video appeared, apparently from a TB2, showing Admiral Makarov on fire. This was clearly fake and taken from a video game – later identified as ARMA 3. One account on Twitter was able to recreate pretty much the same “video” in a matter of minutes.

So, whilst evidence of attacks are a good thing to have to assess whether losses have been taken or not – fake videos tend to sway people in the other direction.

Going back a few days, I believed the Project 03160 Raptor fast patrol boat attacks video from the 2nd of May – but the above now has me thinking otherwise. I did find it a little strange that the second Raptor hung around the area for so long, and didn’t really make much attempt to evade a potential strike. This highlights the problems with creating fake videos for propaganda – once one fake video appears, it makes others seem fake too – whether they are not.

Todays video of the Project 11770 Serna class landing craft being attacked at the Snake Island harbour area certainly got my “fake video” senses twitching when I saw it. Mainly because, by sheer coincidence, I’d obtained imagery of Snake Island from Capella Space, collected on the 4th May, and I’d taken a good look at the harbour area to search for any evidence of ship activity there.

Coupled with the potential fake videos from previous “attacks” one can start to see inconsistencies in this video.

One thing – I always say this regarding my analysis work – I can’t always be right. I like to be, and I take my time on it, but errors will creep in every now and again.

So let’s look at what I see in the imagery versus the video and I can lay my cards on the table with my thoughts – and as always, I’m open to any comments.

First of all, one link to the video on Twitter. It is also available on YouTube I believe.

A number things immediately grabbed my attention. It is visible even in the Twitter image above. All those blocks of squares and rectangles. They look like CGI – too perfect. That area gets pummelled by the sea most of the time. Granted, they could be containers just dumped into the sea, but I’m not convinced at this.

Also, the ramp to the sea looks too perfect – very straight lines, no sea lapping over it. The wall that runs along it, into the sea, is new.

Let’s look at some close-ups from the video.

This one above shows yet more blocks east of the ramp, and strange grooves, much like seating areas. No sea lapping over them.

The next two shows the same area from nearly directly above. Note the near perfect lines of the walls, and more importantly, these blocks again. What are they? Not containers. Maybe concrete block sea defences??

The next image gives an overall view of the harbour area. Note the blocks again, and the coastline itself.

Now let’s look at the Capella imagery.

Whilst not perfect – typically the worst part of the imagery is the harbour – the blocks in theory would stand out. There doesn’t appear to be any. The quality is enough to show the jaggedness of the rocks along the coast, but not much else. There does not appear to be a wall out to sea along the ramp – but this is inconclusive in this imagery.

We can move onto some hi-res imagery from Maxar, though I’m afraid to say I have no contract with them and so I have had to use images from elsewhere. Ideally, we could do with someone that does have a Maxar account – or Maxar themselves – to provide us with the high-res imagery.

The first is taken from a CNN article dated 14th March 2022 and states the image was collected on the 13th. I’ve had to zoom in a little for the screen grab.

Not ideal quality, but does it look like there’s been much of an upgrade to the harbour area? It doesn’t look like there has been. It’s hard to determine whether there are any blocks there.

The following image is reportedly from Planet, collected in the last few days, and published by Associated Press – AP. Whilst I couldn’t find a direct link, there’s plenty out there – for instance.

Moreover, searching in the Maxar archive, there has been a collection on 7th May 2022 which shows smoke coming from the building as shown above, just on the left edge. Note also the ship activity to the west of the island.

With these two images nearly aligning, we can conclude that the top image is very recent.

In my view, whilst there are small buildings near the harbour, one of which in the area east of the ramp – there appears to be no large blocks present. The wall into the sea by the ramp does appear to be present, but hard to determine whether it matches that in the video. It is still too hard to conclude from the imagery currently available whether the blocks are there or not.

Ideally now, then, we need that hi-res imagery that Maxar clearly has (note they’ve redacted the archive imagery of the island). Then we can put this one to bed once and for all.

Analysis isn’t just about seeing what is immediately in front of you. It is much, much deeper than that. Below sums it up nicely.

Just because it looks like Snake Island harbour in the video, doesn’t necessarily mean it is. You have to look at more than just the shape and the jetty.

Ironically, one proven event – the sinking of Moskva – is still to produce any video evidence that a missile attack led to its demise.

Say of that, what you want.

More information on “Bastion-P” Matua Island deployment


  • Deployment day is now known
  • Maxar and Sentinel capture deployment
  • Identity of ships involved now known

Following on from my previous blog on the deployment of Russian K-300P “Bastion-P” mobile coastal defence missile unit to Matua Island, further satellite imagery from Sentinel and Maxar has been found showing the deployment taking place.

Moreover, the Maxar imagey has captured the actual moment the equipment exits the Pacific Fleet Project 775M Ropucha class Large landing ship – and in such detail you can clearly see the personnel filming the event.

The first thing ascertained is that the deployment took place on November 16th 2021, so the Russian MoD took two weeks to release the news. It is also now confirmed that all the support vehicles and personnel deployed at the same time rather than at an earlier date – which I suggested may have been the case in the previous blog.

If you watched the video from the Russian MoD in my last blog, at the beginning of it a Monolit-B mobile coastal surveillance radar vehicle exits the Ropucha class landing ship. The Maxar image clearly shows the Monolit-B on the beach having passed the “film crew”, and a K-300P just exited the ship and still in the breakwater.

The Ropucha can also be clearly identified as Admiral Nevelsky [055].

Imagery of the base for November 16th – the same as that from the ROLES article mentioned in my previous blog – shows little going on so it is likely that a small group of personnel were already there to set up the base, but very little else. However, it is good to get a high resolution of the image now.

Of interest is just how lucky a capture this was. Going through Sentinel-2 imagery, the weather before the 16th, up to today (December 9th), has been cloudy for the vast majority of the time. This is the drawback to normal EO imagery, and is why the SAR imagery capabilities of Capella is important to modern intelligence gathering using satellite imagery.

The Capella image from the 3rd December was collected during a period of 100% cloud cover over the island.

There is absolutely no doubt that both capabilities work in tandem with each other and will make it exceptionally difficult to hide deployments such as these in the future. Capella can provide continuous coverage of a target of interest, and should full EO imagery be required for confirmation of activity and/or actual identities of ships etc. then this can be tasked by the likes of Maxar when weather permits.

The Sentinel-2 imagery, though of low resolution, also revealed the other ships used in the deployment. These consisted of:

  • Project 141 Kashtan class tender KIL-168
  • Project 23470 salvage tug Andrey Stepanov
  • Project 19910 AGS Viktor Faleev

S-AIS data from FleetMon for Andrey Stepanov shows that she arrived at the island on the 14th November, staying for the deployment. She then left the region back to Petropavlovsk-Kamchatsky on the 17th, before returning at the end of the month and arriving on the 27th via Severo-Kurilsk at the island of Paramushir.

A quick hop back to and from Severo-Kurilsk took place over a couple of days, and she is now enroute back to Petropavlovsk-Kamchatsky as we speak.

The FleetMon Sat 15 package was worth its weight in gold for recovering this data

With this activity from Andrey Stepanov and the timing of the Russian MoD news, can one presume that the deployment is now over and just lasted two weeks?

With the Capella imagery showing very little activity at the base on 3rd December, it may well be.

But, it could also be that Andrey Stepanov has been shuttling supplies back and forth to the island – though as a tug is more likely to be there in support of a further ship such as KIL-168. With no S-AIS data available for both KIL-168 and iktor Faleev it could be they were there also. The runway is operational and also capable of taking flights for supply purposes.

For the time being, some further monitoring of the island is required.
