Iran Computer Systems Controlling Rocket and Missile Launchers

Theorganisation is officially known as Iran Computer Systems Controlling Rocket and Missile Launchers and is also referenced by the acronym ICS‑CRML. Its headquarters is situated in Iran, placing it within the country’s defence and technological infrastructure. ICS‑CRML is responsible for the computer systems that command and control rocket and missile launchers used by the Iranian armed forces. These control systems are a core component of Iran’s capability to employ rockets and missiles in operational scenarios.

On 20 June 2019, the United States launched a cyber‑attack aimed at Iranian weapons control systems, specifically targeting the computer infrastructure that operates rocket and missile launchers. The operation was conducted in response to the downing of an American unmanned aerial vehicle and a series of tanker attacks attributed to Iranian forces. The stated objective of the cyber‑attack was to temporarily degrade Iran’s ability to launch rockets and missiles, thereby disrupting its military posture. Publicly available sources did not provide independent verification of the precise extent of damage or disruption inflicted on ICS‑CRML’s systems.

In the aftermath of the cyber‑attack, Iranian cyber actors increased their malicious activities against United States industrial sectors and government agencies. These heightened efforts included attempts to infiltrate and compromise naval systems and other critical infrastructure networks. The escalation took place against a backdrop of rising bilateral tensions driven by renewed sanctions and the United States’ withdrawal from the Joint Comprehensive Plan of Action. The intensified Iranian cyber campaign highlighted the strategic value placed on organisations such as ICS‑CRML within the broader context of the conflict.

ICS‑CRML’s primary focus is the development and maintenance of computer‑based command and control solutions for rocket and missile launchers. This specialisation situates the organisation firmly within Iran’s defence technology sector, distinct from entities engaged in civilian or dual‑use production. Its work centres on ensuring that launch control systems can receive, process, and execute firing orders reliably under operational conditions.

The 2019 cyber‑attack demonstrated how essential ICS‑CRML’s infrastructure is to the operational readiness of Iran’s missile and rocket forces. By disabling the computer systems that govern launchers, the attack sought to create a temporary gap in Iran’s ability to employ its missile arsenal. Consequently, the incident is frequently cited as an illustrative case of state‑level cyber operations directed against weapons control systems.
