The lazy consensus of the Washington defense establishment is as predictable as it is dangerous. Every time a crisis flares up in the Persian Gulf, a parade of retired flag officers marches onto cable news to assure the public that the United States Navy can "keep the sea lanes open" and "control" the Strait of Hormuz.
It is a comforting myth. It is also an absolute fantasy.
I have spent years analyzing maritime choke points and the hard physics of naval warfare. The belief that any modern navy can control a 21-mile-wide strip of water flanked by hostile, asymmetric shorelines is a relic of 20th-century thinking. It ignores the brutal reality of modern anti-access/area denial (A2/AD) capabilities.
We need to stop asking how the U.S. can control the Strait of Hormuz. We need to start admitting that it cannot—and explain why trying to do so is a strategic trap.
The Geography is a Deathtrap
Let's start with the basic geography that the armchair generals love to gloss over.
The Strait of Hormuz is tiny. At its narrowest point, the shipping lanes consist of two two-mile-wide channels for inbound and outbound traffic, separated by a two-mile-wide buffer zone.
[ Iran Coastline ]
---------------------------------- <- Hostile Shore / ASM Sites
2-Mile Inbound Lane
----------------------------------
2-Mile Buffer Zone
----------------------------------
2-Mile Outbound Lane
---------------------------------- <- Omani/UAE Territorial Waters
This is not the open ocean. It is a highway flanked by high ground.
For a multi-billion-dollar destroyer, entering the Strait of Hormuz during a hot conflict is the tactical equivalent of driving an armored vehicle down a narrow alleyway with enemy infantry sitting on the rooftops.
Iran does not need a blue-water navy to close the strait. They do not need to match the U.S. Navy ship-for-ship. They only need to utilize the geography. The entire northern shore of the strait is Iranian territory, dominated by mountainous cliffs perfectly suited for concealing mobile anti-ship missile (ASM) launchers.
The Math of Saturation Attacks
Conventional military analysis relies on "ship vs. ship" comparisons. This is a fundamentally flawed premise.
If the U.S. Navy deploys a Carrier Strike Group to the Gulf of Oman to project power into the strait, it relies on Aegis combat systems to intercept incoming threats. These systems are marvels of engineering. But they are bound by the laws of physics and ammunition capacity.
Consider the math of a saturation attack:
- An Arleigh Burke-class destroyer has 90 to 96 Vertical Launch System (VLS) cells.
- Not all of these cells carry air-defense missiles like the SM-2, SM-6, or ESSM; many are loaded with Tomahawk cruise missiles for land attacks.
- Iran possesses thousands of relatively cheap, shore-based anti-ship cruise missiles (such as the Ghadir and Noor families), alongside swarm-capable fast attack craft and suicide drones.
If Iran launches 80 low-cost drones and cruise missiles simultaneously, a defending destroyer will rapidly deplete its ready-to-fire interceptors. Once those VLS cells are empty, a U.S. warship cannot reload them at sea. It must transit to a secure port to replenish.
In a high-intensity skirmish, the U.S. Navy runs out of bullets long before Iran runs out of cheap projectiles. To pretend otherwise is to deny the basic arithmetic of modern attrition warfare.
The Fallacy of the "Open Sea Lane"
The standard talking point is that the U.S. must guarantee the "free flow of commerce."
But ask yourself: if a shooting war starts in the strait, what commercial shipping company is going to send a $150 million crude carrier through a combat zone?
The moment the first missile is fired, maritime insurance underwriters (like Lloyd's of London) will skyrocket premium rates to prohibitive levels or cancel coverage entirely. No coverage means no shipping.
Even if the U.S. Navy successfully intercepts 95% of incoming Iranian threats, that remaining 5% risk is enough to halt commercial traffic. The strait is closed by economic reality the second the conflict begins, regardless of how many carrier groups the Pentagon parks nearby.
Dismantling the "People Also Ask" Consensus
Googling "Can the US Navy open the Strait of Hormuz?" yields a flood of reassuring articles claiming that a sweep of mine countermeasures (MCM) and airstrikes would clear the path in a matter of days.
This is a dangerous mischaracterization of operations.
"Can't the US just sweep the mines?"
U.S. mine-clearing capabilities are chronically underfunded and aging. The Avenger-class minesweepers are relics, and the Littoral Combat Ship (LCS) mine-countermeasures packages have suffered from years of development delays.
Furthermore, you cannot conduct mine-clearing operations while under active bombardment from shore-based artillery, drones, and cruise missiles. To clear the mines, you must first neutralize the shore-based threats.
"Why not just destroy the shore-based launchers?"
To neutralize Iran’s mobile launchers, you have to find them. The northern coast of the strait is rugged, mountainous, and riddled with fortified underground bunkers—what Iran calls its "missile cities."
A mobile launcher can roll out of a cave, fire, and retreat back into the mountain before an F/A-18 or a satellite can target it. A campaign to fully suppress these launch sites would require a massive, prolonged air campaign, effectively dragging the U.S. into a full-scale regional war.
The Strategic Pivot: Accepting Vulnerability
What is the alternative?
Instead of burning trillions of dollars maintaining a permanent, vulnerable naval footprint in the Persian Gulf to defend a choke point we cannot realistically secure, the United States must change the game entirely.
We must accept that the Strait of Hormuz is a geographic hostage.
If Iran wants to close the strait, they will suffer the most. Iran's economy is utterly dependent on the export of oil and the import of vital goods through those very waters. China, which imports a massive portion of its crude from the Persian Gulf, has far more to lose from a closed strait than a self-sufficient, energy-producing United States.
By attempting to police the strait, we are subsidizing the energy security of our global competitors while putting our most expensive military assets in a shooting gallery.
We must shift our strategy from tactical defense inside the gulf to distant blockade outside of it. If the strait is blocked, we don't fight our way in. We enforce a total embargo on the outer perimeter, choking off Iran's remaining trade while letting the regional powers who actually rely on Middle Eastern oil deal with the economic fallout.
It is time to abandon the fantasy of maritime dominance in a bathtub. The U.S. Navy belongs on the deep blue sea, not squeezed into a coastal choke point waiting for the math of a saturation attack to catch up with it.
