US Destroys Iranian Tankers Following Missile Attacks in Vital Oil Transport Route

Tehran, Wednesday, 9 September 2026.
Following missile attacks on an American warship, the US destroyed five Iranian oil tankers near the Strait of Hormuz, escalating conflicts alongside Iran’s seizure of a high-tech underwater drone.

Military Escalation and Tanker Destruction

On Tuesday, September 8, 2026, US Central Command confirmed the destruction of multiple Iranian tankers following missile attempts on a US navy warship [1][2]. The US military stated that Iranian tankers were struck in the Gulf of Oman and near Iran’s Kharg Island after crews were directed to abandon ship [2]. Centcom described the targeted vessels as part of a multibillion-dollar network funding the IRGC and its regional proxies [1]. This action followed reports that the Islamic Revolutionary Guard Corps twice attempted to strike a US navy warship with ballistic missiles within the preceding 48 hours [1][3]. American officials confirmed that the warship evaded both attempted attacks and no personnel were injured [1]. Secretary of State Marco Rubio stated that the US would not let Iran’s attacks go unanswered, noting that Iran would lose tankers for every attempt made on US naval ships [1]. The exchange marks a resumption of kinetic hostilities after a month of relative calm in August [1].

Dispute Over Unmanned Underwater Vehicle

Concurrent with the tanker strikes, Iran’s Revolutionary Guards claimed to have captured an American unmanned underwater vehicle near the entrance to the Strait of Hormuz at dawn on September 8 [4][6]. Iranian state media identified the vessel as an Anduril Dive-LD autonomous undersea vehicle, describing it as one of the most modern unmanned submarines of the US fleet [3][4]. The IRGC stated the capture was part of a complex intelligence and operational action, promising to release images shortly [6][7]. In contrast, US Navy Captain Tim Hawkins stated the submersible was defective and an older model that neither collected sensitive data nor carried classified equipment [1][3]. The US military characterized the incident as a malfunction occurring more than a day prior to the Iranian announcement [1][3]. Naval analysts note the Dive-LD is approximately 5.8 meters long and weighs around 3 tons, designed for long-endurance missions [5]. Access to such technology could potentially enhance Iranian underwater drone capabilities or be shared with allies [5].

Economic Impact and Strategic Outlook

The Strait of Hormuz normally carries about one fifth of the world’s oil and liquefied natural gas exports, a critical 20 percent of global supply [6]. Iran has maintained a blockade of the strait since the outbreak of the war more than six months ago, while the US has imposed a counter-blockade of Iranian ports [1][6]. Following the renewed exchanges of fire, global oil prices returned to levels last seen in July [1]. The Trump administration is shifting strategy to target Iranian airlines and the oil economy via sanctions, including Operation Economic Outcast announced on September 8 [3][7]. Treasury Secretary Scott Bessent announced sanctions on 36 Iran-linked targets, including 27 airlines, to disrupt illicit cargo movement [7]. President Donald Trump stated that Iran has been punished greatly by the ongoing US naval blockade [7]. Iranian President Masoud Pezeshkian affirmed Iran’s opposition to war but vowed full strength defense against aggression [7]. The Islamabad memorandum, signed in June 2026, established a framework for ending hostilities, though Iran accuses the US of violating commitments [7].
