Undersea Cable Warfare: Iran's Contingency Plans Target Gulf's Digital Lifelines

Exclusive reporting by Reuters, citing two senior Iranian security officials, reveals that Tehran has developed a detailed contingency plan for retaliatory strikes against undersea communication cables in the Persian Gulf, should the nation come under attack by the United States or Israel. This marks a significant escalation in potential cyber and infrastructure warfare tactics.

From Rhetoric to Blueprint: A Strategic Shift

One official stated that if Iran is attacked, "there will be no red lines," indicating that civilian infrastructure, particularly undersea cables, would be considered legitimate targets alongside military sites. A more alarming aspect of the plan involves potential actions to obstruct repair efforts, deliberately prolonging outages of internet and communication services to inflict maximum economic and social disruption.

These plans follow a series of public threats from Iranian military and security figures. Earlier statements from officials within the Islamic Revolutionary Guard Corps had specifically mentioned targeting the seven major internet cables passing under the Strait of Hormuz. Other warnings highlighted data centers and AI facilities in the Gulf region with links to the U.S. as potential objectives.

The Gulf's Digital Achilles' Heel

Damage to these subsea cables would trigger immediate and severe consequences for the region:

  • Internet Connectivity: Widespread outages affecting millions of users and businesses.
  • Financial Transactions
  • E-commerce: A halt to a significant portion of regional online commercial activity.
  • Cloud Services

Alan Mauldin, Research Director at telecoms research firm TeleGeography, provided context: while the Strait of Hormuz carries less than 1% of global international bandwidth—limiting the worldwide impact—the regional effect would be profound. He emphasized that repairing cables in a conflict zone presents extreme challenges, potentially extending outages for weeks or months.

Expanding Risk Map: The Red Sea as a Potential Flashpoint

Beyond the Strait of Hormuz, security analysts are increasingly concerned about the Red Sea. This vital maritime corridor, linking Asia and Europe, is also densely packed with crucial submarine cables. Although Iranian officials have not publicly indicated plans to target infrastructure there, its strategic importance and history of maritime incidents make it a potential secondary risk zone. Any disruption there could cause a wider international communications crisis.

The revelation of these plans underscores a pivotal shift in modern conflict. Critical digital infrastructure is now firmly on the geopolitical chessboard, its vulnerability laid bare by rising tensions. The Gulf region, and the world, must urgently reassess the security and resilience of these deep-sea "digital arteries."
