Analysing the analysis – a closer look at the Saki air base attack satellite imagery


Yesterday – or rather, in the early hours of today – I posted my last blog, Novofedorivka – Saki Air base attack satellite imagery – The aftermath.

In that blog I made a typo. For every word where I meant to say Su-24, I said Su-23. This included in the satellite imagery labelling. So how could this possibly happen as I knew fully that they were Su-24s? I’d called them this correctly in the blog before that and regardless – I know what a Su-24 is.

To add salt to the wound of the error, on my desk next to me at the time of doing the analysis, I had the excellent books by Yefim Gordon & D Komissarov Sukhoi Su-24 and Sukhoi Su-27 & 30/33/34/35. They were still on my desk in the morning when I got up. I’d had the idea on going into a little detail about the aircraft themselves, but changed my mind.

The books still on my desk in the morning.

Looking back at the creation of the blog, I’m pretty sure I know what happened. When I started working on the imagery, when I typed in the first Su-24 label, I inadvertently typed Su-23. This could have been in error by hitting the 3 key instead of the 4, or by just stupidly typing it incorrectly.

From there, the rest is history. I copy/pasted the label for the others in the imagery, and this is where the brain takes over. I subconsciously took in Su-23 as being correct – regardless of knowing what they were, and having pointers near me to correct the mistake (including checking back on the other imagery and blog looking for changes).

Moreover, when it came to proof reading the whole thing, it still slipped through the net again. I even found other mistakes that I rectified.

In other words I totally believed what I was typing and had typed was correct, even though subconsciously I knew it was wrong. And I let it pass – I was seeing what I wanted to see

In my daytime Air Traffic Control world we use the well known term confirmation bias for this.

What is interesting about the whole thing is that just two hours before, in a busy radar session, I was calling a couple of aircraft by the wrong callsign. This is extremely common for us, and for pilots too.

To explain. We have radar screens with data-blocks that show the aircraft callsign, altitude/level, selected level in the flight management system on the aircraft (via ADS-B) and the exit code from UK airspace or last two letters of the destination airfield. We have plenty of other things available to us via Mode-S, but these are selectable.

We also have electronic flight progress strips (eFPS) which has plenty more info on, but the callsign is the obvious one and what I want to look at here.

I can’t remember the exact callsigns, but take an example of EZY12QC – “Easy one two quebec charlie“. I called this one “Easy one two quebec golf” on its first contact, and despite having a eFPS and radar that i was fully interacting with, I continued to do so. It didn’t matter what was in front of me, it was “quebec golf”, not “quebec charlie”. There was at least another flight like that. All was safe as it was checked by the aircrew that the instructions were for them, but it adds extra workload and time to radio transmissions and getting the traffic moving.

An example of aircrew error is taking the wrong calls for other flights with similar callsigns – normally with the same airline, though inter-airline errors do occur. On one occasion, a flight I was working kept taking the call of another that was with the same airline. Eventually, after the fourth or fifth time, he apologised and said he’d been doing that flight the day before and couldn’t get it out of his head – despite coming from Spain and using the correct callsign up until then.

In ATC we use a combination of long term memory, and short term memory. The long term stuff is for things like procedures, sector frequencies etc. Airline callsigns come into this too – their actual airline callsign such as “Easy” for EasyJet, “Speedbird” for British Airways.

The short term stuff is things like co-ordinated agreements with other sectors, the actual traffic picture, flights on frequency etc.

Short term stuff we remove from our brains, once we have no use for it, but we keep the other stuff forever. I still remember things from RAF Lyneham when I was there in 1989!

And, of course, this isn’t an aviation thing. It is present in everything humans do in their lives.

So, how does this affect analysing imagery etc.?

With the last blog, it was probably a combination of being up since 7am, doing an afternoon shift finishing at 2200 UK time that included confirmation bias in the last hour – and then an hours drive home. In other words, a long, tiring day with a fuddled up brain already in place.

Going back to saying that we see what we want to see – analysing imagery has plenty of this.

Not everything of course, but occasionally it creeps in. And it happens to everyone.

I’ll take the Saki attack “aftermath” as a prime example of this as I think there’s several places this has happened. And I’m just going to say this now – this is not a direct dig at anyone in particular.

In fact, I’ll start with one of mine – or a possible one. I’ve been watching Saki since 2014 so know it pretty well I think. I also have access to some fantastic data on the base.

The two buildings destroyed at the revetments are known “workshops” used by the Russians for quick repairs to aircraft. Often this has entailed taking parts from one aircraft to put onto another to keep the fleet “airworthy”. This is likely why there was a Su-24 at the eastern building. Parts are stored in one of the revetments west of the building.

The two concrete parking areas also targeted were for vehicles, equipment and spare parts – often kept in boxes or crates. One has been referenced as a building in some analysis and on social media. This is completely wrong. You only have to look back through Google Earth history to see that often there are Su-24s parked there. But people are seeing what they want to see – and to be honest, being a little lazy and not checking themselves. It doesn’t take much to go back through GE history.

I have all this information stored in my head as long term memory and that is what I believe these areas are used for. At some stage over the last few months, and in particular over the last few days, these buildings and parking areas have become weapons storage areas according to reports and social media. Where this came from I have no idea, but certainly, since the attack they have been known as “ammo storage buildings”.

Likely, the main reason for this is because the number of boxes and crates has increased since the beginning of the war – and they’re green. My confirmation bias says these are all sorts of equipment, whereas others say they are ammo boxes because this is what they’ve read/been told; and their confirmation bias won’t say otherwise. Ammo boxes are being seen because they are green – and well, so are ammo boxes.

One of the concrete areas has white torpedo like objects. These are Su-24 3,000 litre external fuel tanks that they carry on the inner pylons, under the wings. In the aftermath imagery you can see they have been shifted by the power of the nearby explosion. These have been referenced to missiles in storage. They’re not.

In reality, we don’t actually know what was in these green boxes and crates. Logic tells me it isn’t all munitions as they have hardened areas specifically for this. But, the Russian forces do have open munitions storage areas located at bases all over the country so who is to say? More than likely, it will be a mix of things.

The real confirmation bias from this incident comes it at the main apron. The Planet imagery I provided for the morning before the attack showed three Su-24’s and three Su-30’s parked on the main flight line.

There are a number of things to note – referencing the first image below. Firstly, the aircraft follow white taxiway lines to a white square to stop and shut down. These squares are clearly visible where aircraft aren’t parked.

Secondly, next to each parking spot there is equipment used with the aircraft. Starter generators, wheel chocks, ladders and other things needed for the aircraft. These can be seen in between the parked aircraft in the imagery.

The last thing to note is that there isn’t an aircraft parked on the far west spot – this is the spot that in the post attack imagery there is supposedly a destroyed Su-24. As there’s no wreckage present, this can’t be confirmed 100%, but photos and video have been produced that do show a destroyed Su-24. Actually, in the post attack imagery the burnt area centres on the equipment between the parking spots.

Looking at the second image below you can clearly see all the equipment still in place. But many saw these as destroyed aircraft – and Hey, Presto! six more aircraft that are actually over to the east of the base have been destroyed!

Total confirmation bias – you are seeing what you want to see. Because we all want to see Russia fail (well not everyone, obviously).

And yet all the clues are there. At the probable destroyed Su-24 area, there’s a completely burnt out patch covering the parking squares – yet for the “other six” there isn’t. The obvious equipment – seen in imagery just 24 hours before – is ignored and declared as wrecks.

Whilst the aircraft that were on the flightline probably didn’t escape some damage, from confirmation bias we have claims that the whole fleet of aircraft were totally destroyed – and whilst it was a very successful attack – it wasn’t as successful as is claimed.

This leads to misinformation – and what I call ” Bad OSINT”.

Novofedorivka – Saki Air base attack satellite imagery – The aftermath


It took a long time in coming, but imagery is available of the destruction caused at Saki (Saky) air base in Crimea.

Unfortunately, being at real work has delayed this analysis, but it’s worth putting out there anyway. Plus the imagery shows the majority of the airfield rather than just the main parking area. This alone provides some interesting information.

Primarily, the 43rd Independent Naval Attack Aviation Regiment of the Black Sea fleet has taken a bit of a hit. Definitely, three Su-30SM’s have been destroyed with one probably damaged. Moreover, four Su-24’s are destroyed in the revetment area – with the possibility of another on the main apron.

The Su-24 on the apron is inconclusive. There’s definitely an area that has been cleared – there’s vehicles around it etc. – but the imagery from earlier in the day doesn’t show an aircraft in that actual spot.

Most certainly, no other aircraft were destroyed where they parked on the main flightline. This is obvious from the ability to see all the “parking squares” and lack of burnt areas. If a Su-24 (or other aircraft) was destroyed at the scorched area then they have removed the wreckage pretty quickly – possibly to hide what happened, but the rest of the airfield gives it all away.

Most of the aircraft destruction is in the revetments – ironically used to protect aircraft from events like this. If only the Russian’s used HAS’s (Hardened Air Shelters) – they may not be feeling the pain. The good news is, they are.

The revetments have given up three Su-24’s and three Su-30’s. A further Su-24 is destroyed at the eastern maintenance minor workshop shed.

And this is where it all gets interesting.

The actual targets.

Two minor workshop sheds have been totally targeted and destroyed. Moreover, two other areas that were targeted – or appeared to have been – were general parking areas used for vehicles and equipment.

It is strange that the two large munitions areas and the fuel depots were also not targeted. And to be honest, if an aircraft has been destroyed on the main flightline, I suspect this is from secondary explosions and fire rather than a direct strike as there is no crater present. Why wasn’t this area targeted?

The area around the parking revetments is dotted with small craters, possibly from debris. But they do look more like explosive craters rather than that caused by falling debris.

A vast majority of the airfield grass areas has been burnt. This could have potentially spread to the burnt out cars that have been seen in videos – though one has certainly been destroyed by debris from explosions. @wammezz on Twitter produced a false-colour image of the whole base which clearly shows the extent of the burnt ground.

There’s been a number of aircraft movements since the event. A Su-30SM is now in the main maintenance area – possibly the one from the revetment nearby that is now missing. And whilst the number of Su-24’s in this area remain the same, either one has been removed/moved, or there’s been a change around.

Obviously, the main flightline has been emptied, as has the eastern secondary line, except for a single Su-30SM. A Su-23 has been relocated to just south of this area.

Three helicopters have departed, whilst the three remaining have been rotated to point east.

Due to costs I couldn’t get a full airfield view from Planet so it is possible some of the aircraft have been moved to the eastern airfield revetments.

There is still no conclusive evidence as to what was used in this attack.

I’ve always thought a Ukrainian SF mission – which I didn’t want to say in the other blog as it was still a recent event and there was a slight OPSEC concern with me to be honest. The Ukrainian armed forces have stated it was a SF mission also.

However, the craters visible do point to a missile strike, with a good friend betting a ATACMS strike.

I’m still torn.

Maybe the maintenance sheds held more than scrap parts of aircraft to keep the main line going from day to day. I’d like to say the Russians aren’t that stupid – but since March, they’ve clearly shown they are.

Whilst it is good to see the evidence of destruction in Crimea – finally – the event has almost created more questions than answers.

Novofedorivka – Saki Air base attack satellite imagery


Videos and photographs of an attack on the Novofedorivka – Saky air base in Crimea on 9 August 2022 starting appearing on social media just around lunchtime, UK time.

Early indications point to multiple areas being attacked on the air base. It is yet to be ascertained as to what has been targeted – and how exactly the attacks have taken place. Or if it was yet another accident that the Russian forces seem to be very good at having.

The explosions shown – possibly up to 12 of them – look to come from the area of munition storage facilities, and/or the fuel depot on the base.

The number of explosions does point more to an attack than an accident, but weapons “cooking off” and hitting other areas causing further explosions can’t be counted out – regardless of the initial cause of the explosions.

Saky is home to the 43rd Independent Naval Attack Aviation Regiment of the Black Sea fleet, operating Su-30SM, Su-24M and Su-24MR fighter aircraft.

The base also has an area for training for operations on Project 1143.5 CVGM Admiral Kuznetsov and has replica flight deck & ski ramp used to practice taking off from, and landing on, the carrier.

Satellite imagery captured by Planet at 0810z on 9 August 2022 – approximately 4 hours before the attack – shows based aircraft on the main apron and parking areas, as well as helicopters parked at the Southwestern part of the base at the replica Kuznetsov deck/landing area.

The size of explosions shown in videos does point to there likely being heavy damage and a large number of casualties.

The next question is – what was used in the attack? If, indeed, it was one.

As far as is known, the Ukrainian forces do not have a missile strike capability of the range needed from the frontline to the base location.

I’m sure more news will be coming forthwith.

Admiral Kuznetsov dry dock update

**Update to the small update**

**Imagery amendment – The northern floating crane at the dock entrance is actually a fixed one on the wall. – Thanks to Capt(N) for posting an image that shows this**

A few more Capella Space collection passes were tasked after Admiral Kuznetsov was moved to the 35th Shipyard dry dock.

These were dated 26 and 27 May 2022.

They show that work has started again on the dry dock entrance. Here they will likely seal the mouth up with a temporary steel barrier that has been pile driven into the river bed. From that they can then empty the dry dock and construct the full gate system.

Why they didn’t do this at the time of construction is anyone’s guess, but it is likely they wanted Kuznetsov into the dock as soon as possible so that they can continue the work on the ship.

Three floating cranes appear to be back in attendance to help with the work. The image for 27 May looks like a barrier is already in place, but this is the northern crane.

They used this method to construct the dry dock in the first place, but had to destroy it so that Kuznetsov could be floated in.

In theory, they could use the dry dock as soon as it is empty for any work on the hull that would normally be below the waterline, but this could be dangerous. And with the luck Kuznetsov has had recently…. well, anything could happen!

But, the Russian Navy does appear to like risk and I think they’ll put the lower dock to work as soon as they can. Especially if Kuznetsov has been damaged below the waterline in the previous incidents.

Admiral Kuznetsov on the move – but not far!

With rumours filtering through that Project 1143.5 CVGM Admiral Kuznetsov was due to move sometime between 17 and 19 May 2022 from its “temporary” mooring position in Murmansk to a purpose built dry dock just a little further south, I set up at collection task with Capella Space to catch before and after imagery of the event.

Kuznetsov had ended up at its mooring position after floating dock PD-50, of the 85th shipyard, sank on 30 October 2018 whilst the CVGM was being floated out after a month of works. During the accident, a crane that was part of the dock fell onto the flight deck causing considerable damage.

That wasn’t the end of the woes for the already delayed refit Kuznetsov was undertaking – originally planned to start in 2017 and already a year late. On 12 December 2019 the ship suffered from a major fire that the United Shipbuilding Corporation (USC) estimated would cost 350 million roubles ($4.7 million/£3.7 million at the time) to repair.

An agreement was made with the Russian MoD that two dry docks of the 35th shipyard in Murmansk would be redesigned and knocked through into one large dry dock that could take Kuznetsov and other large Russian navy ships and submarines.

Work commenced on the new dry dock mid to late 2019 and was due to be completed in early 2021 for Kuznetsov to enter and complete the overhaul. Currently, the 35th Shipyard are restricted to works that can take place alongside.

However, the dry dock is still under construction due to several delays in the construction process. This hasn’t deterred the Russian navy from getting Kuznetsov into the dock.

On 20 May 2022, Kuznetsov made the 1.5 km journey with the assistance of tugs rather than under its own power.

Telegram poster, Arctic Observer – Murmansk (Арктический обозреватель – Мурманск) was the first to post imagery of Kuznetsov on the move on 20 May.

They then posted further imagery a little later.

Capella Imagery

The collection request was made to Capella to cover 17 – 20 May. Typically there wasn’t a collection slot available on the 20th, but the request was extended to the next available on the 22nd.

Low resolution EO imagery on Sentinel was only available for 15 May. After this, the region was 100% cloud covered, making further collections of EO imagery impossible. This is where SAR collections from Capella excel – being able to see, no matter the weather.

Sentinel imagery dated 15/5/22 showing Kuznetsov and the “new” dry dock to the south

19 May 2022. Work appears to have been paused at the dry dock and the entrance cleared.
19 May 2022. At Kuznetsov, a possible tug or floating crane is present. No such activity was taking place on the previous days collections.
22 May 2022. Kuznetsov in the dry dock at 35th Shipyard.

FleetMon S-AIS data

The move used at least four tugs according to S-AIS data from FleetMon. These were – Bizon, Grumant, Helius and Kapitan Shebalkin.

FleetMon AIS data shows Tug Bizon alongside Kuznetsov on 20 May 2022.
FleetMon AIS data shows Tug Grumant alongside Kuznetsov on 20 May 2022.
FleetMon track history for Tug Grumant clearly shows it helped with the Kuznetsov move. All the other tugs mentioned also showed similar tracks to this.
FleetMon AIS data shows Tug Helius working at the dry dock on 20 May 2022.
FleetMon AIS data shows Tug Kapitan Shebalkin alongside Kuznetsov and at the dry dock on 20 May 2022.

Since 20 May, further imagery has been published that shows Kuznetsov in the dry dock. bmpd on LiveJournal has some particularly good ones which showed some of the work being carried out.

A couple of the images are interesting as they show potential changes to the weapons systems. Below, it can be seen that the RBU-12000 ASW rocket launchers (designed specifically for Kuznetsov) have been retained (central, far left of image) but the AK-630M on the deck balcony below has been removed.

The same has taken place on the starboard side of the ship.

A further image on RIA Novosti credited to Pavel Lvov, taken from above also shows the removal of the AK-630Ms along with the eight Kortik/Kashtan CADS-N-1A each fitted with twin AO-18K (6K30GM) 30 mm rotary cannon and eight SA‐N‐11 (9M311) ‘Grison’ missiles.

The Kashtan is likely to be replaced by Pantsir‐M/Pantsir‐SM CIWS hence their removal.

The image above also shows a lot of surface oil. Whether it is from Kuznetsov or the tugs is anyone’s guess – but I have a feeling I know which one it is
