Naval maneuvers: how the imperialist americans plan to block Iranian ports.
Is Washington capable of completely closing the Strait of Hormuz, and how will Tehran respond?
At 17:00 Moscow time, the United States launched a naval operation in the Strait of Hormuz, restricting access to Iranian ports. The operation will involve marines in boats and helicopters, aircraft carriers, amphibious assault ships, and guided missile destroyers, according to military experts interviewed by Izvestia. For their own safety, U.S. ships will likely have to maintain a considerable distance from the shores of the Islamic Republic. The Iranian leadership is expected to use all available means—from anti-ship missiles to drones and underwater kamikaze drones—to damage the enemy fleet. However, sustaining resistance to the blockade over a prolonged period will be difficult given the significant military and technological superiority of the United States, experts say.
How Iranian ports could be closed
Forces of the United States Central Command (CENTCOM) began blocking, at 17:00 Moscow time, all vessels entering and leaving Iranian ports. The ban applies to ships of all countries, the command announced.
“CENTCOM forces will not interfere with the freedom of navigation of vessels transiting the Strait of Hormuz to or from non-Iranian ports,” the command clarified.
Earlier, U.S. President Donald Trump announced the possibility of imposing a blockade on the Strait of Hormuz. He stated that U.S. warships could stop vessels attempting to pass through the strait in violation of restrictions.
According to military expert Dmitry Kornev, Washington’s announcement of a naval blockade against Iran implies establishing full control over the Persian Gulf.
“Technically, this means a regime under which no ship will be able to enter or leave Iranian ports,” he explained to Izvestia.
However, any seizure of ships by U.S. warships would be illegal.
“This contradicts all laws governing civilian maritime transport,” said military expert Yuri Knutov.
Oil is not the only concern: the U.S. blockade of the Strait of Hormuz will even affect China.
Following the failure of a meeting between the United States and Iran in Islamabad, tensions in the Persian Gulf region are rising.
What will they use to enforce the blockade?
The U.S. Navy has all the necessary forces to strictly block both the Strait of Hormuz and Iranian ports. Tracking traffic in this area of the world’s oceans will not be a problem. Modern reconnaissance systems—satellites, airborne early warning (AEW) aircraft, and drones—make it possible to track ships at long distances, even if they switch off their transponders, devices that report a vessel’s location, speed, and other parameters, experts told Izvestia.
Yuri Knutov believes that five or six destroyers would be sufficient to block major sea routes and create an effective blockade.
“The U.S. Navy would not need to deploy all its warships concentrated in the region to carry out such an operation,” the expert said.
According to Dmitry Kornev, the Persian Gulf can be blocked by a squadron of Arleigh Burke-class destroyers.
Their onboard Mk41 universal launchers with Standard and Tomahawk missiles allow them to destroy large targets as well as forcibly stop vessels for inspection.
“Additional support will be provided by a carrier strike group (CSG) and expeditionary forces led by amphibious assault ships,” Kornev explained.
Only small vessels or coastal craft would be able to bypass such a barrier, but tanker fleets and large bulk carriers would find the blockade insurmountable, experts believe.
How will ships be stopped?
The procedure for intercepting vessels is well known and has been practiced repeatedly in recent years. First, the crew is contacted by radio and asked to change course or stop. If the vessel does not comply, an aircraft or helicopter may fly over and warn the intruder by firing along its route, demonstrating readiness to use force.
“An armed team of U.S. marines will be sent from a military vessel to board that tanker or other civilian ship,” said Yuri Knutov.
Helicopter units and fast boats allow inspection operations to be carried out quickly at a considerable distance from the fleet’s main forces.
Even if a ship manages to escape the immediate blockade zone, it may be intercepted on the high seas and escorted to a port of an allied state, for example, Oman.
“We have all the necessary resources for this: bases and ports, as well as the ability to intercept a ship at a considerable distance from the conflict zone,” the expert explained.
Will Iran break the blockade?
The key question lies in Iran’s readiness for a decisive military breakthrough. The Islamic Republic’s surface fleet is significantly inferior to that of the United States, so Tehran is likely to resort to an asymmetric response.
“Iran will use Shahed-type kamikaze drones to saturate U.S. ships’ air defense systems, or it will attempt to strike targets with coastal anti-ship missile systems,” Dmitry Kornev added.
Unmanned boats and autonomous underwater vehicles loaded with explosives cannot be ruled out.
According to experts, this threat will force the United States to keep its fleet as far as possible from Iran’s coast to avoid unnecessary risks; even damage to a single large warship, not to mention its loss, would be a serious blow to the U.S. image.
However, the question remains how long and how effectively Iran will be able to carry out such attacks. While Iran may be capable of delivering a one-time strike against a U.S. squadron, conducting a sustained operation to lift the blockade under the United States’ total technical superiority would be extremely difficult.
“For now, the likelihood of a successful forced breakthrough of the blockade appears low, although the risk of direct military clashes remains significant,” Dmitry Kornev concluded.
Why is the United States imposing a blockade?
The decision by U.S. Central Command to initiate a naval blockade against Iran is a classic example of a “symmetrical response” in geopolitics. Washington’s main objective is clear: to force Tehran to reopen the Strait of Hormuz, according to Middle East expert Kirill Semenov.
“The situation is developing as a mirror reflection of reality. Iran has blocked a key transport route—the Strait of Hormuz—and in response, the United States is trying to completely paralyze Iranian shipping and port operations. In essence, Washington is saying: ‘Your ships will not move until you open the strait to the international community,’” he explained.
According to the expert, this move reflects several strategic calculations by the Trump administration. The first is to avoid direct military escalation. At this stage, the port blockade appears to be an attempt to resolve the issue without large-scale airstrikes or an invasion. The United States is trying to defeat Iran with its own tools: creating a logistical and economic deadlock.
“The second factor is Iran’s diplomatic isolation,” Semenov believes. “If Tehran responds to the blockade with attacks on U.S. bases in the region or on Arab Gulf ports, the global perception of the conflict will change. In that case, Iran risks losing even minimal international support, as it will be seen as the initiator of the ‘hot’ phase of the war.”
It is clear that the blockade will not yield immediate results. However, over time—likely not a short period—economic pressure could become critical. The expectation is that internal problems will force Iranian leaders to make concessions, Semenov explained.
According to experts, other countries will also suffer from the consequences of the blockade.
“For China, the main geopolitical rival of the United States, this is not so frightening. Its oil reserves will last almost 300 days,” Yuri Knutov noted.
The countries most affected by this situation will be India and several Southeast Asian nations that have not built up strategic reserves; many experts believe serious fuel shortages could arise there.
