STRAIT OF HORMUZ — Iranian Revolutionary Guard Corps gunboats attacked several commercial ships in the Strait of Hormuz on Wednesday. The attack came as President Trump announced he was unilaterally extending a ceasefire to allow more time for peace talks.

Roughly 60% of the naval arm of the Islamic Revolutionary Guard Corps, including fast-attack speed boats, remained intact as of the start of the ceasefire in early April. That naval arm is hampering oil shipping traffic in the Strait of Hormuz.

Battle damage assessments show that the joint operation destroyed much of Iran's conventional navy. Pentagon spokesman Sean Parnell said that 92% of the Iranian Navy's largest vessels have been destroyed and about 44 minelayers have been destroyed.

Trump and Defense Secretary Pete Hegseth described Operation Epic Fury as essentially destroying Iran's military capacity. "By any measure, Epic Fury decimated Iran's military and rendered it combat ineffective for years to come," Hegseth said.

The head of the Defense Intelligence Agency submitted a written statement ahead of a House Armed Services Committee hearing saying Iran can still inflict damage. "Iran retains thousands of missiles and one-way attack UAVs that can threaten U.S. and partner forces throughout the region, despite degradations to its capabilities from both attrition and expenditure," Marine Lt. Gen. James Adams wrote.

About half of Iran's stockpile of ballistic missiles and associated launch systems remained intact as of the start of the ceasefire. About two-thirds of Iran's air force remained operational after a U.S. and Israeli campaign that struck thousands of targets, including storage and production facilities. Iran's air power has been degraded but not eliminated.
