Strait of Hormuz Live-Fire Drills Underway; Mariners Warned of Elevated Risk

Iran has commenced a two-day live-fire naval exercise in the Strait of Hormuz, scheduled for 1–2 February 2026, according to multiple news sources. The drills were announced via maritime navigational warnings to vessels in the region. 

The strait is among the world’s most vital shipping lanes, with about 20 % of global oil supplies transiting daily. 

The United States Central Command issued a warning on 31 January that any “unsafe or unprofessional behavior” near commercial vessels during the exercises could increase the risk of collision, escalation, and destabilization. It reiterated Iran’s right to conduct exercises while urging adherence to professional conduct to avoid inadvertent incidents. 

Regional maritime advisories and notices to mariners have cautioned ships to exercise heightened vigilance, maintain proper separation from exercise zones, and continuously monitor VHF Channel 16 for updates. 

Why it matters for maritime

The Strait of Hormuz is a narrow corridor linking the Persian Gulf to the Gulf of Oman and the Arabian Sea, making it a strategic artery for crude oil, LNG, and general cargo movement globally. Any unsafe interactions with military exercises can pose significant navigational hazards for commercial and tanker traffic in proximity to the drills. 

Mariners operating in or near the strait should follow official navigational warnings, adjust routes if necessary, and maintain open communications with coastal authorities to mitigate risk during the ongoing live-fire activity.
