Ukraine's Foreign Intelligence Service (HUR) has obtained data indicating that Russia is planning a significant expansion of its officially flagged oil tanker fleet, a move the agency links directly to growing Western pressure on Moscow's shadow shipping network — and to what it describes as a new vector for hybrid operations against Europe.
According to HUR, Russia's Federal Autonomous Institution "Russian Maritime Register of Shipping" — currently under EU sanctions — is preparing to identify and inspect approximately 80 tankers in the near term, with the aim of re-registering them under the Russian flag. The vessels currently sail under the flags of the Seychelles (35 ships), China (23), Azerbaijan (13), and Samoa (8), with additional tankers registered to owners in Vietnam, India, the UAE, and the Marshall Islands.
The intelligence service reports that the decision was driven by a pattern of detentions: European countries and the United States have been seizing shadow fleet vessels with increasing frequency, making third-country registration less reliable as a shield. Re-flagging under Russia's own banner, HUR says, is Moscow's response to that pressure.
The implications, according to the agency, extend well beyond oil revenues. "Increasing the shadow fleet under the Russian flag automatically makes it easier for Russia to embed intelligence service agents on board for the purpose of conducting reconnaissance and sabotage operations against Western countries," HUR states in the assessment. The Baltic region is singled out as the primary exposure point: more than 40 percent of Russia's maritime oil exports pass through it.
The agency is direct about the broader strategic logic: registration under the Russian flag, it says, "definitively frees the Kremlin's hands" in using such vessels as instruments of hybrid threats against Europe and other Western nations.
HUR points to a concrete recent precedent. The tanker BELLA 1 (IMO 9230880), which the service describes as having transported oil for the benefit of Iran and Venezuela, received Russian registration immediately after it was caught flying a false flag of Guyana — an episode that occurred in January 2026. The case is cited as evidence that re-flagging is already being used as an emergency cover mechanism when shadow fleet vessels are exposed.
The intelligence also points to a possible Iran dimension. HUR says the re-flagging drive may reflect coordination between Russia and Iran on securing safe passage for shadow fleet vessels through the Middle East conflict zone — adding a regional layer to what is otherwise framed as a European security concern.
