Why Can’t the US Escort Oil Tankers Through the Strait of Hormuz?

Operation Epic Fury has seen the US Navy forgo 1980s-style convoy escorts in the Strait of Hormuz, opting instead for a distant blockade from the Gulf of Oman. This strategic shift reflects direct US belligerency against Iran, contrasting sharply with the defensive posture of Operation Earnest Will during the Iran-Iraq War.

Decades of studying American military interventions in Iraq and Afghanistan prompted the Islamic Revolutionary Guard Corps to construct deep underground bunkers, decentralized command networks, and dense anti-access missile arsenals along the Persian Gulf littoral. Forced into a fight for regime survival on what Sun Tzu termed "death ground," Iranian forces retain the capacity to saturate narrow waterways with uncrewed aerial vehicles and anti-ship munitions. Consequently, American strike aircraft and naval units must prioritize distant suppression of Iranian coastal infrastructure over close commercial vessel protection, altering the operational balance across regional energy chokepoints.

Comment
The transition from Operation Earnest Will's defensive convoy mechanics to offensive distant blockade operations demonstrates how anti-access capabilities fundamentally alter littoral warfare. Strategic decentralisation of strike authority within the Islamic Revolutionary Guard Corps renders close naval escorts inside the Strait of Hormuz operationally untenable against massed uncrewed platforms. Surface combatants tethered to slow-moving commercial traffic face immediate saturation from dispersed, hardened coastal launchers along the Iranian littoral. Consequently, modern sea control in restricted chokepoints hinges on suppressing land-based fires via deep-strike sorties rather than maintaining a direct physical presence along the shipping lane.
Strategic Question for Discussion
If the Islamic Revolutionary Guard Corps maintains decentralised launch authority during a sustained campaign, which factor plays a larger role in suppressing shore-based anti-ship fires — deep-strike ammunition inventories or persistent real-time intelligence coverage?
