UPDATE: Following our previous coverage of the KOSATKA's (IMO 1011551) movements from Severomorsk to Severodvinsk (link in comments), SynMax's maritime domain awareness platform, Theia, has identified Vladimir Putin's superyacht more than 5,900km to the east, alongside Petropavlovsk-Kamchatsky, on Russia's Pacific coast.
The KOSATKA was last identified at Severodvinsk on the 17th of August 2026. She was next detected by Theia on the 13th of September, having transited the length of Russia's Arctic coastline via the Northern Sea Route to reach Kamchatka.
Petropavlovsk-Kamchatsky sits on Avacha Bay, home to Russia's Pacific Fleet, including the Rybachiy submarine base at Vilyuchinsk on the opposite shore. It is assessed that her arrival marks a further stage in the vessel's relocation away from European Russia, though the purpose of her presence at Kamchatka has not been confirmed.
The 82-meter superyacht, formerly named GRACEFUL, was sanctioned by the United States in 2022, shortly after which she was renamed. She departed the Baltic Sea under naval escort in late June 2026, reportedly amid concerns over the reach of Ukrainian long-range drones, before being tracked by Theia to Severomorsk and subsequently Severodvinsk.
Theia ingests more than 40 million km² of satellite imagery daily, fusing EO, SAR, and AIS data to automatically detect, identify, and track tens of thousands of vessels across oceans, regardless of AIS status. SynMax's Agentic AI, Atlas, provides automatic alerts on vessels of interest, delivering actionable intelligence on high-value targets regardless of how far, or how dark, they travel.

UPDATE: Following our previous post on the KOSATKA's (IMO 1011551) arrival at Severomorsk, Russia (link in comments), SynMax's maritime domain awareness platform, Theia, has identified Putin’s yacht alongside Severodvinsk.
The KOSATKA's last detection at Severomorsk was on the 7th of August. She was identified at Severodvinsk on the 17th, approximately 350km to the southwest.
The 82-meter superyacht, formerly named GRACEFUL, is widely linked to Russian President Vladimir Putin and was sanctioned by the United States in 2022, shortly after which she was renamed. She had not transmitted on AIS since 2022, before briefly reappearing last June, when she departed the Baltic Sea under naval escort, reportedly bound for the Arctic amid concerns of Ukrainian long-range drones.
Severodvinsk is home to the Sevmash shipyard, where the KOSATKA's hull was originally laid down.

Following our previous report (link in comments) on the hijacking of the HONOUR 25 (IMO 1099735), the SWARD (IMO 9174244), and the M/T EUREKA (IMO 1022823), the resurgence of Somali piracy along the Puntland coast has continued to escalate, with three further vessels seized since our last update.
On the 17th of July 2026, the ASANA (IMO 9035838), a 127-meter, Tanzanian-flagged oil and chemical tanker built in 1992, was hijacked approximately 65 nautical miles southwest of Al Mukalla, Yemen, shortly after departing the port.
On the 17th of August 2026, the LUTUF (IMO 9109134), a Cameroon-flagged cargo vessel reportedly carrying equipment destined for a Turkish military training facility in Mogadishu, was boarded approximately four nautical miles off Mareeyo, in Puntland's Eyl district. Following a 10-day joint operation conducted by the Turkish Navy and the Somali National Armed Forces, during which four pirate skiffs were reportedly destroyed and 14 pirates killed, the LUTUF was freed on the 29th of August. Puntland authorities have disputed this account, alleging that an unconfirmed ransom secured her release.
On the 20th of August 2026, the SIBU 1 (IMO 9204776), an Eritrean-flagged oil products tanker previously named SEAMULL and sanctioned by OFAC for her alleged role in Iran's shadow fleet, was hijacked approximately 136 nautical miles east of Al Mukalla, Yemen, and taken toward the Puntland coast, becoming the sixth vessel seized since the 21st of April.
On the 11th of September, the SWARD and her crew, imaged on the 7th of September, were released from captivity after a ransom was reported to have been paid.
SynMax's maritime domain awareness platform, Theia, continues to maintain visual custody of the vessels still under pirate control. Between the 2nd and 7th of September 2026, Theia detected the SIBU 1, ASANA, and M/T EUREKA AIS dark, and the HONOUR 25 and SWARD AIS light, all distributed across the Puntland coastline.
Four commercial vessels and dozens of seafarers remain under pirate control. The geographic spread of these hijackings is consistent with the reconstitution of a pirate action group network capable of sustained, long-range operations.
Theia ingests more than 40 million km² of satellite imagery daily, fusing electro-optical and SAR imagery with AIS to automatically detect, identify, and track tens of thousands of vessels, regardless of their signal output. Tip-and-cue capabilities automatically task high-resolution imagery of vessels of interest, while SynMax's Agentic AI enables the precise interrogation of vast, preprocessed datasets to expose true unknown unknowns.

Between the 21st of April and the 2nd of May 2026, three commercial vessels were hijacked off the coast of Somalia and Yemen in a significant resurgence of Somali piracy, assessed to be highly likely carried out by Somali pirate action groups (PAGs) operating from the Puntland coast.
The HONOUR 25 (IMO 1099735), the SWARD (IMO 9174244), and the M/T EUREKA (IMO 1022823) remain under pirate control. SynMax's maritime domain awareness platform, Theia, has tracked the vessels throughout their ordeals, detecting each off the Puntland coast as recently as the 28th of May.
The HONOUR 25 (IMO 1099735) is a Palau-registered product tanker. She was seized on the 21st of April while en route from Berbera, Somaliland, to Mogadishu, while laden with refined oil. Theia detected her on the 28th of May, anchored off the Puntland coast south of Bayla.
On the 26th of April, the SWARD (IMO 9174244), a 100-meter general cargo ship built in 1998 and flagged in St. Kitts and Nevis, was hijacked approximately six nautical miles northeast of Garacad, Somalia. At the time, she was reportedly transiting to Mombasa with a cargo of cement. Theia imaged her on the 28th of May in the vicinity of Dhingwda, approximately 200km south of the other two vessels.
The M/T EUREKA (IMO 1022823) is an 88-meter, Togo-flagged product tanker, built in 2006. She was seized off Yemen's Shabwa coast on the 2nd of May while transporting diesel from the UAE. Continuous tracking and the ability to dynamically tip-and-cue high-resolution imagery enabled the tasking of @Satellogic imagery of the M/T EUREKA on the 23rd of May, confirming her position in the vicinity of Bayla.
The geographic spread of the three vessels along the Puntland coastline is consistent with established patterns of Somali piracy. It is believed that organized crime groups in Somalia are taking advantage of the Iran war to launch hijackings, as international naval patrols, first deployed in 2008 to counter the pirates, have been stretched thin by current events around Hormuz and the Red Sea.
Theia ingests more than 40 million km² of satellite imagery daily, fusing electro-optical and SAR imagery with real-time global AIS to automatically detect, identify, and track tens of thousands of vessels, regardless of their signal output. Tip-and-cue capabilities automatically task high-resolution imagery of vessels of interest, while SynMax's Agentic AI enables the precise interrogation of vast, preprocessed datasets, massively increasing analysts' capacity and exposing true unknown unknowns.

When Reuters set out to establish whether Moscow was still resupplying its Syrian bases under the new agreement with Damascus, the answer sat in the traffic off the coast. SynMax tracked a four-vessel Russian convoy into the Syrian port of Tartus on September 7, the first resupply of Moscow's coastal facilities since the August 9 agreement on Russia's military presence in the country.

We are a mission first, customer focused company. Adding Merlin data helps us serve our customers and advance our mission as we deliver MDA intelligence. But we aren’t the only ones delivering MDA products. We have many competitors offering products and services that can benefit customers, too.
We’re not gatekeepers. We’re customer focused, not competitor focused. That means we’ll offer imagery alone, analytics, or any part of the value we create at a fair price to customers in friendly nations; including our competitors.
If you need our products, whether you’re an end customer or a competitor building something with our data, we’re open and happy to do business. We don’t have to be the only provider involved for the mission and the customer to win.
Mission first. Customer first! @SynMaxInt
Satellogic and @SynMaxInt are collaborating on next-generation maritime domain awareness through our upcoming Merlin constellation.
Through this agreement, SynMax’s Theia platform will exclusively deliver Merlin-driven maritime intelligence—pairing near-daily 1m-class imagery and co-collected AIS data with AI analytics to track dark vessels, monitor sanctions evasion, and combat IUU fishing.
Together, we are transforming maritime domain awareness from episodic image collection into persistent monitoring at scale.

In the final part of our four-part spoofing series, we explore how AIS spoofing became a go-to tactic for the shadow fleet.
AIS spoofing didn't arrive fully formed. It's a tactic that developed over roughly 25 years, evolving in response to technology and regulatory pressure. Through the 1990s and 2000s, AIS was a trust-based safety tool built to prevent collisions. The only evasion tactic needed was switching it off.
As satellite tracking matured through the 2010s, a gap in coverage became suspicious in itself. Bad actors shifted from absence to deception. Identity theft and false location spoofing emerged, driven by sanctions on North Korea, Iran, Syria, and Venezuela. Spoofing became a digital alibi for vessels trading with sanctioned states.
This came to the attention of the international community in 2018, when the UN found that the tanker YUK TUNG (IMO 9030591) had transmitted false AIS data, posing as another vessel during a ship-to-ship transfer with a North Korean tanker. Regulators began treating spoofing as deliberate evasion rather than a data error.
Tactics kept advancing. Identity laundering and "zombie ships" emerged, manufacturing clean identities instead of borrowing them. Location spoofing moved from basic geometric patterns (images 1 & 2) to complex, plausible vessel paths. The line between commercial and state-level coordination blurred.
Russia's 2022 invasion of Ukraine and the sanctions that followed drove a step change. What had been a limited tactic became the shadow fleet: hundreds of aging tankers, often uninsured, falsely flagged, or registered under minimal-oversight flag states. AIS spoofing moved from niche to industrial scale.
The good news is that regulators are catching up. Recent sanctions guidance now names AIS manipulation alongside ship-to-ship transfers, false documentation, and flag-hopping as recognized evasion techniques. The question is no longer whether a vessel is transmitting, but whether the transmission is true.
Detection advances, evasion adapts. The constant is structural: AIS is self-reported, so verification has to come from outside the signal. As spoofing grows more sophisticated, enforcement has to adopt the practices maritime security professionals already use: fusing and cross-referencing multiple sources rather than trusting a single signal. No longer a definitive record of identity or movement, AIS is one data source among many.
This is the principle on which Theia is built. By fusing over 40 million km² of daily satellite imagery with global AIS, SAR, and additional intelligence sources, Theia establishes ground truth independent of any single signal's claim. Atlas, SynMax's Agentic AI, lets analysts interrogate that fused dataset directly, surfacing suspicious behavior regardless of AIS output or compliance status.

On the 30th of August, SynMax's maritime domain awareness platform, Theia, detected the AIS dark Russian battlecruiser ADMIRAL NAKHIMOV underway in the White Sea (65.6083, 39.5791), reportedly conducting sea trials.
The Northern Fleet's 250-meter Kirov-class nuclear-powered warship last operated in 1997, before entering an extended overhaul at the Sevmash shipyard in Severodvinsk. A modernization program began in 2014, though it wasn’t until 2025 that the ADMIRAL NAKHIMOV operated under her own power. In June 2026, Russia's Ministry of Transport announced that the vessel had entered the final phase of sea trials.
Theia tip-and-cued partner @Satellogic’s high-resolution satellite imagery of the ADMIRAL NAKHIMOV alongside Sevmash on the 19th and 29th of July 2026. The imagery shows a significant change in the coloration of her deck.
Ingesting more than 40 million km² of satellite imagery daily, Theia fuses electro-optical imagery with global AIS data and more to automatically detect, identify, and track vessels regardless of their transmission status. SynMax’s Agentic AI, Atlas, automatically analyzes Theia’s data, establishing patterns of life of strategic vessels and waterways and alerting users to significant trends and activity.

Persistent Global Intelligence is a much bigger deal for SATL IMO. I didn’t see as much of a reaction to that as I expected.
Satellite companies face a frustrating constraint. They are unintentionally competing with ground based sensors because they can’t scale their biggest use case advantage: object location discovery.
To task a satellite you pick a location and they charge by the square kilometer. That inherently limits them to cases where you already know the target location. When you already know location the value of a satellite image is what additional intelligence can be pulled from a new image of the known location. That favors higher resolution, high revisit and low latency. Compared to ground based sensors satellites lose on all those qualities.
A satellites real advantage is location search. For a use case where you don’t know the targets location ground sensors are at a disadvantage meanwhile satellites are flying around the fucking earth. Think searching for a moving target like a mobile rocket launcher. Satellites pass over your target and every target location constantly according to their revisit rate.
So why don’t they just let you know when they found your target? Lots of reasons: downlink bandwidth and processing mostly. In short the satellite has no idea it’s over anything important and it can only download so many images anyways. SATL solved that problem with Merlin’s edge compute and some novel AI that lets them profile targets in mass, persistently match them to your target and (for a fee) tell you where anything is anywhere on the face of the earth instantly. Read that last line again, every adversary tank, convoy, rocket launcher, aircraft, supply vehicle all of it everywhere.
Governments spend billions hunting and pecking with satellites to try and find these things like searching a dark room with a flashlight . SATL is turning on the lights.
(Everywhere except the ocean of course, that’s where we come in 😉.)

UPDATE: Following our previous post on the KOSATKA's (IMO 1011551) arrival at Severomorsk, Russia (link in comments), SynMax's maritime domain awareness platform, Theia, has identified Putin’s yacht alongside Severodvinsk.
The KOSATKA's last detection at Severomorsk was on the 7th of August. She was identified at Severodvinsk on the 17th, approximately 350km to the southwest.
The 82-meter superyacht, formerly named GRACEFUL, is widely linked to Russian President Vladimir Putin and was sanctioned by the United States in 2022, shortly after which she was renamed. She had not transmitted on AIS since 2022, before briefly reappearing last June, when she departed the Baltic Sea under naval escort, reportedly bound for the Arctic amid concerns of Ukrainian long-range drones.
Severodvinsk is home to the Sevmash shipyard, where the KOSATKA's hull was originally laid down.
Theia ingests more than 40 million km² of satellite imagery daily, fusing EO, SAR, and AIS data to automatically detect, identify, and track tens of thousands of vessels across oceans, regardless of AIS status.

The KOSATKA (IMO 1011551), a 82-metre superyacht formerly known as GRACEFUL and widely linked to Vladimir Putin, has arrived at Severomorsk, Russia, on the Kola Peninsula, following a voyage north from the Baltic under naval escort by the destroyer SEVEROMORSK and patrol vessel VOEVODA.
Sanctioned by the United States in 2022 and renamed shortly afterward, the KOSATKA had not transmitted on AIS since August 2022, before briefly reappearing in late June 2026. The relocation follows a pattern of Russian-linked superyachts moving away from Baltic and Black Sea anchorages in recent weeks, amid concern over the reach of Ukrainian long-range drones.
SynMax's maritime domain awareness platform, Theia, detected the KOSATKA alongside in Severomorsk (red outline), near a cluster of naval and support vessels, enabling the tip-and-cue of @Satellogic high-resolution imagery.
Theia fuses more than 40 million km² of daily satellite imagery with global AIS and additional intelligence sources to automatically detect, identify, and track tens of thousands of vessels across oceans, regardless of AIS status. Theia's Agentic AI, Atlas, can be configured to alert analysts the moment a vessel of interest becomes active again, whether through a resumed AIS transmission or a fresh detection, ensuring no reappearance goes unnoticed, regardless of how long a vessel has been dark.
