The fact that the tankers are running through the Hormuz Strait in daylight, and during coverage by commercial satellite is a good indicator that volume of oil will continue to increase. What we are missing is information from @CENTCOM and @US5thFleet on the details on how these escorts are being performed - which for obvious reasons they do not wish to diverge. The other piece of evidence has been the lack of attacks on ships in the Gulf of Oman conducting ship-to-ship transfers. While we may not see US Navy warships in the Strait, they may be present on the GoO protecting these anchorages and catching the outbound tankers from Hormuz and providing coverage for the return ships. If you want am idea of what ships are codnucting these passages, they are probably the ships on @PGSA_IRAN Non-Compliance list. The Tanker War of 2026 is evolving into a major naval campaign that will force the @USNavy and @POTUS to rethink the role of commercial shipping, Sea Power and trade defense.
Five VLCC tankers loaded with crude spotted 👇 at daybreak YESTERDAY, finishing their eastbound US 🇺🇸 route transit of the Strait of Hormuz at 25.9580, 56.5581 No cakewalk. Pretty dangerous sailing under fire. Note characteristic thin long Iran 🇮🇷 hit ship bunker fuel slick .👇

The Philippine Navy issued a radio challenge to a People’s Liberation Army Navy (PLA-N) warship monitored about 10 nautical miles from participating vessels during the ADMM-Plus Sea Phase in the West Philippine Sea. But unlike usual radio challenges, the PH Navy invited the Chinese warship to join the formations, given China’s membership in the ADMM-Plus. “We have a warship that is a country part of our ASEAN and Plus countries. We are always ready to accommodate them during the exercise,” Combined Task Force Commander Capt. Miljun Peñaflorida told reporters aboard the BRP Jose Rizal. The Chinese warship never responded. @ABSCBNNews

The 🇮🇷 container ship FLEXI 2 (IMO 9246322) transited the North Sea toward the Skagerrak, with its destination listed as the 🇷🇺 port of Bronka, near St. Petersburg. While transiting the Dover Strait, FLEXI 2 made two unusual U-turns for unknown reasons. It will soon transit the Danish Straits into the Baltic Sea. EU Directive 2025/811 requires Mandatory Ship Reporting of key safety information, including insurance certificates due to substandard ships that pose substantial risks to maritime safety and marine ecosystems. -- See the @UANI Iran Shipping Update for more details: unitedagainstnucleariran.com… -- @JemimaShelley @mercoglianos @brentdsadler @TankerTrackers @imannasseri @YorukIsik @SONARROW_OSINT @steffanwatkins @auonsson

This is what it looks like on your radar in Taiwan Strait. Singapore strait adds big merchant vessels as well to the mix. Those clusters are big fishing fleets.

Taiwan Coast Guard intercepts and drives away intruders to Pratas waters At approximately 5:00 a.m. on September 7, the Southeast and South China Sea Branch's Pratas Command under the Coast Guard Administration (CGA) detected the China Coast Guard vessel "3501" located outside Taiwan's restricted waters off Pratas Island. Based on its heading, the vessel was projected to enter the restricted waters, prompting the immediate dispatch of the patrol vessel Yunlin to deploy for interception. At 8:00 a.m., the Coast Guard vessel "3501" entered the restricted waters from the southwest of Pratas Island. The Yunlin immediately moved in to run parallel, monitor the vessel, and broadcast stern warnings in both Chinese and English to drive it away. Thus far in 2026 ,Taiwan Coast Guard has driven away China Coast Guard vessels in the Pratas waters for a total of 12 voyages. The Coast Guard Administration emphasizes that Taiwan holds indisputable sovereignty over the Pratas Atoll and its surrounding waters. It strongly condemnes China's attempts to engage in cognitive warfare through political manipulation—creating an illusion of jurisdiction under the pretext of "law enforcement." The CGA will continue to take all necessary measures to ensure the security of Taiwan's maritime domains.

We must have free and open commerce and waterways. The U.S. and our allies will continue to take decisive action against naval terrorists like the Houthis and the Iranian regime.
