Iran’s Missile Attacks Dropped 90%. The Last 10% Is the Problem Nobody Can Solve

Iran’s Missile Attacks Have Dropped 90% Since the War Began — U.S. Intelligence Still Can’t Say How Many Are Hidden in Underground Missile Cities

Iranian missile attacks dropped by as much as 90 percent since the opening days of Operation Epic Fury

Yet, there is a lingering, and likely troubling, question about what kind of remaining arsenal the Iranian Revolutionary Guard Corps has. 

The IRGC is still launching attacks, and many of their ballistic missiles operate with precision guidance technologies such as inertial navigation systems or GPS.

Despite the more than 13,000 bombing sorties over Iran and the devastation unleashed by Operation Epic Fury upon Iran’s missile stockpile, the IRGC does seem to remain capable of offensive missile attacks. 

There are several key factors to consider here.

One factor may be Iran’s potential strategy; Iran is known to have massive underground missile cities where it stores small boats, drones, and missiles, and it is likely difficult for U.S. and Israeli commanders to locate exactly where all of them are. 

Iran is known to have spent decades building up its missile arsenal in anticipation of this kind of war scenario

How much does Iran have left

Is the IRGC deliberately holding back to ensure it retains offensive attack capability for weeks or months into the future in the event of protracted conflict?

This strategy, if true, may yield some short-term benefits, yet Operation Epic Fury has targeted Iran’s production capacity and destroyed missile and drone manufacturing locations.

Iran’s ability to maintain its arsenal over time would seem to be very much in question, given the destruction caused by Epic Fury. 

Iran Still Has Missiles

At the moment, however, multiple news reports are citing a U.S. intelligence community assessment that found that Iran does, indeed, still maintain a sizable weapons arsenal. 

A report in the New York Times cites U.S. intelligence findings that Iran’s use of decoy launchers makes it difficult for U.S. commanders to know how many they have left. 

Other reports claim that the Iranians are having success rebuilding launchers and reconstituting underground storage areas by digging them out of the rubble after airstrikes. 

Escape U.S. Targeting

The difficulty Iran will likely face, however, will be in sustaining this over the long term, given the targeting, ISR, and sensor-to-shooter times the U.S. military is capable of achieving.

For instance, U.S. command and control linking aerial drones with fixed-wing attack planes and ground-based command sensors has created a situation in which targets can be hit within minutes, or even seconds, of being seen by drones, sensors, or aircraft.

There is very little latency, and the often-described sensor-to-shooter connection is increasingly networked and fortified by AI-enabled computing. 

Therefore, launchers do not have much time to shoot, because once they emerge, they are quickly seen and destroyed by U.S. airpower. 

If Iran’s ability to build missiles is crippled or destroyed, then it will inevitably hit a wall at some point and lose the ability to launch attacks. 

New Iranian Weapons

Yet another concern concerns the range. 

During his address to the nation, President Donald Trump said there were long-range Iranian missile capabilities that were previously unknown. 

He went on to say they had been destroyed by U.S. airpower, yet it does make sense in light of open-source analysis of Iran’s missile arsenal.

An interesting assessment in an essay titled “Iran Watch” from the Center for Strategic and International Studies mentioned a new, long-range variant of the Iranian missile, the Khorramshahr, capable of reaching 3,000km. 

This range can naturally place parts of Europe at risk, and this missile variant may be the reason why Iran was able to fire a missile as far as Diego Garcia.
