Geopolitical Tensions EscalateUS Bunker Buster Deployment Signals Heightened Risk in Strait of Hormuz
March 18, 2026
Hundreds of tankers and freighters are currently stranded in the Persian Gulf as the Strait of Hormuz is presently impassable. The US military is now targeting Iranian missile positions in the region with a weapon that was last deployed during the Twelve-Day War last summer.
The US Armed Forces have reportedly deployed bunker-busting bombs to strike heavily fortified Iranian missile positions in the Strait of Hormuz. “Several” of the deep-penetration bombs, each weighing nearly 2.3 tons, have been “successfully employed,” according to a statement from the US Regional Command for the Middle East (Centcom).
This specialized ammunition, designed for exceptional penetration, is typically used against particularly reinforced facilities or underground bunkers. When the US entered the war between Israel and Iran last June, the Air Force used bunker-busting bombs against Iranian nuclear facilities. According to the US military, the recent attack targeted positions with cruise missiles that could be used against ships, posing “a threat to maritime traffic in the Strait.”
The Strait of Hormuz, located between the Persian Gulf and the Gulf of Oman, is a vital artery for international oil and liquid gas trade. Following the American-Israeli attacks in Iran, Tehran has repeatedly threatened to attack ships passing through the strait. Shipping traffic in the strait has practically come to a standstill since the start of the war approximately two and a half weeks ago. Hundreds of tankers, container ships, and freighters are currently stranded in the region. According to data from the International Maritime Organization (IMO), Iran has so far attacked 16 commercial ships, resulting in injuries and several fatalities.
There is currently no international support for a US-President Trump-desired escort through the Strait of Hormuz. At its narrowest point, the strait is only 25 to 40 kilometers wide. Accordingly, there would be little room for 200 to 400-meter-long tankers as well as warships to maneuver. The area “favors the attacker,” explained shipbroker SSY to the trade publication Argus Media.
Escalation Risks and Potential Outcomes
The deployment of bunker-busting bombs represents a significant escalation in tensions. The narrow confines of the Strait of Hormuz amplify the risks, creating a scenario where miscalculation could quickly spiral into a wider conflict. The area is particularly vulnerable due to the limited maneuvering space for vessels.
Impact on Global Energy Markets
The disruption to shipping in the Strait of Hormuz, through which approximately one-third of the world’s oil supply passes, has already caused significant concern in global energy markets. Prolonged closure or instability could lead to substantial price increases and supply shortages. The current situation has hundreds of tankers and freighters stranded in the region.
The Role of the Revolutionary Guard
The Iranian Revolutionary Guard’s (IRGC) actions and rhetoric are central to the current crisis. The IRGC has repeatedly warned of retaliation for attacks on Iranian interests and has demonstrated a willingness to disrupt shipping lanes. The IRGC is “waiting” for US convoys, according to a spokesperson.
Future Scenarios and Potential De-escalation
Several scenarios could unfold. Continued escalation could lead to direct military confrontation between the US, and Iran. Alternatively, diplomatic efforts, potentially through indirect negotiations, could lead to a de-escalation of tensions. The outcome will likely depend on the willingness of all parties to exercise restraint and engage in meaningful dialogue.
