Iran claims second underwater drone seizure in Strait of Hormuz during September.
Iran's Revolutionary Guards have claimed seizure of a second underwater drone in the Strait of Hormuz during September, according to statements from Tehran. The seizure follows earlier claims of capturing an American Remus 600 underwater drone in the same waterway.
Both incidents occurred at Hormuz Island in Hormozgan province, positioning the seizures within Iran's claimed territorial waters. The back-to-back drone captures represent escalating naval operations in the strategically critical strait, which has become a focal point for US-Iran military activity throughout 2026.
The drone seizures add another dimension to the Strait of Hormuz conflict beyond surface and air operations. These incidents occur amid broader maritime tensions, including the ongoing diplomatic impasse over strait reopening proposals and previous Iranian military strikes on US installations. The accumulation of naval incidents—from drone seizures to pipeline attacks and territorial consolidation by regional actors—reflects intensifying competition for control over critical waterways affecting global energy security.

Drone Seizures Signal Iranian Naval Dominance in Strait
The back-to-back underwater drone seizures demonstrate Iran's operational capacity to detect and capture advanced surveillance equipment in contested waters. These incidents establish Iran's control over the Strait of Hormuz at subsurface levels, complementing surface and air operations. The seizures indicate Tehran has developed effective counterintelligence capabilities targeting US reconnaissance platforms.
Underwater Operations Expand Naval Conflict Beyond Surface Warfare
The drone seizures introduce subsurface dimensions to the Strait of Hormuz conflict, previously dominated by surface engagements and airstrikes. This escalation suggests both nations have extended military competition to deeper operational layers. The incidents underscore how contested waters now involve multiple domains—surface, air, and underwater—intensifying overall maritime instability in the critical chokepoint.
