Core Event: Boarding of the Sanctioned Super-tanker Davina
On the night of 5 June 2026, U.S. Indo-Pacific Command (INDOPACOM) forces conducted a right-of-visit boarding of the stateless oil tanker M/T Davina, also listed as Lenore, about 20 miles southwest of Sri Lanka in the Indian Ocean. The vessel was reportedly near-full of crude oil. Helicopters and a Lewis B. Puller-class expeditionary mobile base boarded the ship, which had its anchor down.
Background: U.S. Maritime Blockade on Iran
Washington has imposed a maritime blockade on Iran’s sea trade after Tehran began firing on commercial ships transiting the Strait of Hormuz. The blockade targets vessels that provide material support to Iran, including those transporting Iranian crude oil. The Davina interdiction follows a series of U.S. actions against commercial and oil tankers in the Indian Ocean and Bay of Bengal since mid-April 2026.
Timeline of Recent Interdictions
Key recent interdictions: In October 2024 the United States sanctioned Davina/Lenore for Iranian oil trade. On 21 April 2026 INDOPACOM seized the stateless tanker Tifani; two days later, on 23 April, the Majestic X (Phonix) was stopped. In May, the vessel Skywave (Blue Gulf) was reported halted, though the Pentagon did not formally acknowledge it. The Davina boarding occurred on 5 June 2026.
Vessel Profile and Operational Data
Davina is a 300,976-dwt super-tanker capable of carrying up to two million barrels of crude oil. Since 2024, the vessel is reported to have transported roughly 20 million barrels of Iranian oil. It has operated under false registries, claiming a flag of Curaçao and previously Palau. INDOPACOM data indicate that, as of 5 June, U.S. forces have redirected 129 commercial vessels and disabled six to enforce the blockade, while three stateless tankers have been seized since mid-April.
Official U.S. Statements
INDOPACOM announced the boarding via an X post, emphasizing continued “global maritime enforcement to disrupt illicit networks and interdict vessels providing material support to Iran, wherever they operate.” The statement frames the action as part of a broader effort to enforce the blockade and protect international shipping lanes.
Conflicting Reports and Information Gaps
Sources differ on the vessel’s name, alternating between Davina and Lenore, and on its registry status. While some reports cite three stateless tankers seized since April, a separate Pentagon release mentions 129 commercial vessels redirected and six disabled, creating a discrepancy in the scale of enforcement. No details were provided regarding the ultimate destination of Davina’s cargo or the identities of its owners and operators after the October 2024 sale.

Outlook: Future Maritime Enforcement
INDOPACOM indicated that the boarding of Davina is part of an ongoing series of interdictions. U.S. officials expect continued patrols and right-of-visit operations in the Indian Ocean to enforce the blockade, signaling sustained pressure on vessels linked to Iran’s oil exports.
