U.S. military says it used sea drones in combat for first time to strike Iranian port facility

The U.S. military on July 14 released video footage it described as the first combat use of sea drones, saying the operation involved an attack on an Iranian submarine and a ship maintenance facility at a naval base near Bandar Abbas, Iran.

CBS News reported that the Pentagon shared the material alongside its account of the strike, presenting the footage as evidence of a new category of unmanned maritime capability being used during hostilities. The report characterized the action as an assault on both operational and support infrastructure, targeting a submarine and facilities used for maintaining ships.

The attack was described as taking place at the Bandar Abbas naval base, a location that carries significance for Iran’s ability to support naval operations in the Persian Gulf region. By targeting a combination of a submarine and a maintenance site, the military account linked the use of sea drones to an effort to disrupt both active assets and their upkeep.

While the U.S. account focused on the technology and the intended targets, CBS News did not provide additional independently verified details in its report about damage extent, operational impact on any specific vessel, or casualties. As with many wartime claims, the full assessment of effects could depend on later intelligence and on what Iran discloses publicly.

The release of the video also underscored how quickly unmanned systems are being integrated into combat roles at sea. The U.S. description of a “first” in combat use suggests a shift from unmanned maritime systems being used only for reconnaissance or other non-kinetic missions to direct strike operations.

The incident comes amid ongoing U.S.-Iran confrontation dynamics that frequently involve maritime risk, operational indicating, and contested claims about attacks and counterattacks. In that environment, the U.S. decision to publicly share combat footage can be read as part of a broader pattern of communicating military capability to deter further actions and to shape international understanding of incidents at sea.

For Iran and regional partners, a U.S. strike narrative that names specific targets and highlights new operational technology raises immediate questions about maritime security, surveillance, and countermeasures. The next steps for both sides will likely include further official statements and, over time, assessments of whether the strike achieved the operational disruption described by U.S. officials.
