New Missile Doctrine and Recent Launches
Iran’s state news agency reported that the solid-fueled Qassem Basir missile was showcased as part of a “new doctrine” in which Tehran will act against any perceived threat before it materializes. The head of Iran’s Supreme National Security Council, Mohsen Rezaei, said the missile had been “tested” against a U.S. warship, though it was not confirmed whether the test involved the Qassem Basir itself. The United States said ballistic missiles were launched at U.S. warships on the preceding weekend and responded by striking three Iranian oil tankers. U.S. officials reported that its warships evaded the attacks.
Background and Context
The conflict began on February 28 when U.S. and Israeli forces struck Iranian targets, initiating a war that has since expanded to the Gulf and the Strait of Hormuz. Prior to the recent escalation, Iran’s missile program had been a focal point of U.S. and Israeli security concerns, and its attacks at sea were largely directed at commercial shipping for six months.
Data and Statistics
- Qassem Basir: solid-fueled, half-ton warhead, advertised range of at least 1,200 km (? 745 mi).
- U.S. naval response: 94 commercial vessels were redirected and three were disabled following the missile launches.
- Jordanian interception (Sept 9, 2026): Jordan’s air-defense systems destroyed 18 of 20 ballistic missiles launched from Iran; the remaining two landed in unpopulated areas.
- CENTCOM actions: five Iranian crude-oil carriers were destroyed, including three on Sept 5, 2026, after Iran attempted attacks on a U.S. aircraft carrier and guided-missile destroyer.
- Shipping impact: Kpler noted a sharp drop in transits through the Strait, with an average of ten commodity ships per day in the past ten days—the lowest since May.
- Oil market reaction: Brent crude futures reached $97.93 a barrel, the highest since July 24, before easing to $96.19.
Official Statements & Responses
- Rafael Grossi, IAEA Director General: “The best, shortest way for a positive outcome is for Iran to engage with us.”
- Mohsen Rezaei: “We will only commit to the Strait of Hormuz being open when they (the Americans) stop the sabotage, threats and attacks on Iran.” He announced plans for a new restricted zone extending from the U.S. naval blockade into the Gulf, with vessels entering the zone to be placed on an Iranian sanctions list.
- Mohammad Baqer Qalibaf, Speaker of Iran’s Parliament: warned that any strike on Iranian assets would be met with retaliation.
- U.S. White House: Declared the Strait of Hormuz open and under U.S. control, noting that the Navy had cleared mines and that tanker traffic to non-Iranian ports would increase.
- Jordanian military spokesperson: Confirmed the successful interception of 18 missiles and urged civilians to avoid suspicious debris.
On-the-Ground Reports
Jordan’s rapid interception demonstrated regional air-defense capabilities amid the missile barrage. Kpler’s data on reduced transits underscores the immediate commercial fallout, while UAE presidential adviser Anwar Gargash warned that no single state should control the strait and that the United Arab Emirates is developing alternative export routes.
Conflicting Reports & Gaps
Sources differ on whether the missile launched at the U.S. warship was the newly unveiled Qassem Basir or an earlier model, as Iran’s state media did not specify the exact type. Iranian officials claim the test validated the new doctrine; U.S. officials have not confirmed the missile’s performance characteristics.
