California joins Guam, Hawaii, Washington, Oregon, Alaska, Mariana Islands and more as the FBI warns the West Coast and Pacific territories of a potential interception threat from Iran amid the ongoing crisis in the Middle East, prompting heightened vigilance across U.S. security and defense networks. The alert follows intelligence reports suggesting that Iran may have explored launching unmanned aerial drones from vessels positioned near American waters, raising concerns about possible threats to ports, military bases and critical infrastructure. As geopolitical tensions linked to the ongoing Middle East crisis continue to escalate, federal and local authorities are increasing monitoring and preparedness across the West Coast and Pacific territories, ensuring that California, Guam, Hawaii, Washington, Oregon, Alaska and the Mariana Islands remain on alert for any potential interception threat from Iran.

FBI Warns of Possible Iranian Drone Threats to the U.S. West Coast

The FBI has reportedly warned police departments in California about a potential threat of Iranian drone attacks targeting the US West Coast in retaliation for American military strikes against Iran. According to reports, intelligence suggested that Iran may have explored launching unmanned aerial vehicles from a vessel positioned off the U.S. coastline, possibly aimed at unspecified targets in California. Authorities say there is currently no confirmed timeline, method, or specific target linked to the alleged threat. Security experts note that the alert is intended to help federal, state and local agencies prepare for potential risks. Officials have also expressed concern that advanced drone technology could be used by hostile actors operating through international networks.

California – Alleged Drone Threats Near Major Ports and Infrastructure

U.S. intelligence alerts indicate California could be the central focus of a potential Iranian drone threat scenario. According to summarized intelligence from early February 2026, Iran allegedly explored launching Shahed-style kamikaze drones from a vessel positioned in international waters off the U.S. West Coast. The vessel is believed to be a modified civilian cargo ship operating as a “mystery platform.” While the potential targets remain unspecified, analysts believe strategic locations such as the ports of Los Angeles and Long Beach or major power infrastructure could be among the most likely objectives. These ports represent some of the busiest trade gateways in the United States, making them critical nodes in global supply chains and a high-impact target for any asymmetric disruption attempt.

Guam – Strategic Military Hub Considered a High-Value Target

Guam remains one of the most strategically important U.S. military bases in the Pacific, and intelligence assessments have placed the island under heightened security measures. The territory is currently operating under FPCON Bravo, a security condition used when an increased and predictable threat of terrorist activity exists. Analysts believe Iranian proxies could consider Guam a high-value retaliatory target because it serves as a key launch point for U.S. long-range bomber operations, including B-52 and B-2 aircraft deployments supporting missions in the Middle East. Any disruption to Guam’s infrastructure or military operations could affect broader regional security dynamics and American strategic reach across the Indo-Pacific theater.

Hawaii – Concerns Over Maritime Sleeper Cells Near Pearl Harbor

Security alerts also highlight concerns about potential maritime sleeper cells operating near Hawaii. Although there is no confirmed vessel-based drone threat specifically targeting the islands, intelligence reports warn that certain ships may have quietly positioned drone launch systems or electronic signal-jamming equipment in waters near Pearl Harbor long before current geopolitical tensions escalated. Such a scenario could allow hostile actors to rapidly deploy disruptive technologies targeting communications, surveillance networks or naval operations in the region. Pearl Harbor remains one of the most important naval bases for the United States, making any potential threat to its operational stability a matter of serious national security attention.

Washington – Naval Infrastructure and Submarine Bases at Risk

Officials have also identified Washington state as a potential vulnerability zone, particularly around naval installations in the Puget Sound region. Intelligence assessments warn that threats may not be limited to airborne drones but could also involve underwater unmanned vehicles, sometimes called UUVs. These underwater drones could theoretically be used to approach naval facilities and target the hulls of docked submarines or other vessels. Puget Sound is home to major naval shipyards and submarine support infrastructure, making it a crucial part of the United States’ maritime defense network. Monitoring of maritime activity around these facilities has reportedly increased as authorities examine potential vulnerabilities.

Oregon – Energy Terminals Seen as “Soft Targets”

Oregon’s coastal infrastructure has also drawn attention in security briefings because of the presence of energy terminals that handle significant fuel shipments. Intelligence summaries describe these sites as potential “soft targets” because they generally have fewer air-defense systems compared with heavily protected military facilities in nearby states. In an asymmetric attack scenario, energy terminals could be attractive targets because even a limited disruption might affect regional fuel supplies and economic activity. Authorities are therefore reviewing protective measures around these facilities while maintaining increased surveillance of maritime traffic along the state’s coastline.

Alaska – Radar Installations Monitoring Potential Drone Activity

Despite its remote geography, Alaska plays a critical role in U.S. early-warning defense systems. Intelligence alerts indicate that radar installations such as the Ballistic Missile Early Warning System (BMEWS) are operating under heightened monitoring conditions. Analysts believe hostile actors could theoretically launch high-altitude drones from vessels positioned in the North Pacific to test American air-defense response times and identify potential surveillance gaps. Such activity would not necessarily aim to cause direct damage but could serve as a probing operation designed to gather intelligence about U.S. detection and interception capabilities across the Arctic and Pacific approaches.

Mariana Islands – Monitoring Vessel-Based Threats in Strategic Pacific Corridor

The Mariana Islands, which include several U.S. military facilities and logistics hubs, are also under close observation. Intelligence warnings suggest that vessel-borne threats could emerge in the region, particularly if hostile actors attempt to hide among normal commercial shipping traffic. Authorities have expressed concern that civilian vessels could potentially be used as cover or “human shields” for equipment associated with drone launches or surveillance operations. Because the Mariana Islands sit along critical maritime routes connecting the Western Pacific and the United States, maintaining security in the region is considered essential for protecting both military operations and global shipping networks.

How the U.S. Is Preparing to Counter Potential Drone Threats

U.S. authorities are implementing a multi-layered security strategy designed to detect, disrupt and neutralize potential drone threats before they reach American territory. The approach combines military operations abroad with homeland defense measures and intelligence monitoring. Officials say the strategy focuses on degrading hostile capabilities overseas while strengthening defensive systems along the U.S. mainland and maritime approaches. Key elements of the response include:

• Operation “Epic Fury” – Offensive Defense: U.S. strikes have reportedly targeted Iranian naval assets and drone-related infrastructure, including the destruction of more than 30 vessels and facilities linked to drone production.
• Domestic “Shields Up” Measures: Counter-UAS systems and electronic jamming technology have been deployed at major West Coast ports to disable or intercept drones.
• Coast Guard Maritime Surveillance: AI-assisted satellite monitoring is being used to track vessels operating without active identification signals near U.S. waters.
• Border and Cybersecurity Monitoring: Authorities are increasing surveillance along the southern border while placing critical infrastructure and power grid operators on heightened cyber defense alerts.

California Governor Gavin Newsom Says State Monitoring Security Risks Amid Middle East Tensions

California Governor Gavin Newsom addressed concerns about potential security threats in a post on X, noting that state authorities remain closely engaged with security and intelligence agencies while monitoring developments related to the conflict in the Middle East. Newsom emphasized that officials are maintaining constant communication with emergency management teams to ensure preparedness across the state. In his message, he stated: “I am in constant coordination with security and intelligence officials, including at @Cal_OES, to monitor potential threats to California — including those tied to the conflict in the Middle East. While we are not aware of any imminent threats at this time, we remain prepared for any emergency in our state.” The statement reflects ongoing vigilance among California officials despite the absence of an immediate threat.
