IRGC Navy Warns USS Frank E. Petersen Jr. During Hormuz Mine Sweep as 850 Vessels Wait

Summary
June 15 radio traffic from the IRGC Navy told USS Frank E. Petersen Jr. “This is the last warning” as the destroyer conducted mine-clearance operations in the Strait of Hormuz, hours after the US-Iran MOU was electronically signed.
US Central Command launched the sweep because Iran had declared the strait closed on June 11, and Tehran’s later notice allowing “non-hostile” transit only with “Iranian coordination” went beyond the MOU’s described terms.
One commercial vessel — India-flagged LNG tanker Disha — crossed Hormuz in the first 48 hours after signing, while no crude or product tanker followed and 850 vessels remained anchored on either side as of June 17.
Saudi Arabia’s Marjan, Safaniya, Zuluf and Abu Safa offshore fields have been shut since March, wiping out 2 million to 2.5 million barrels per day and leaving skeleton crews about 100 kilometers from where the warning was broadcast.
Brent still fell 5.23% to $78.82 on June 16 as traders bet on eventual reopening, but maritime and Pentagon estimates suggest commercial confidence could take 40 to 50 days to recover and full clearance up to six months.

Overview
Between June 15 and 19, 2026, Iran’s Islamic Revolutionary Guard Corps (IRGC) issued a significant warning, creating an immediate standoff that overshadowed ongoing diplomatic efforts for a US-Iran ceasefire. This warning led to an atmosphere of uncertainty just as hopes were rising for a resolution, with both sides preparing for a crucial Geneva ceremony. Despite the tension, diplomatic channels remained active, focusing on a Memorandum of Understanding and confirming high-level signatories. The commitment from both sides highlights a persistent drive for peace, even as military posturing and uncertainty challenge the path forward.
