Us Drone Expert Warns Iran Could Strike California at Any Moment

As tensions between Washington and Tehran intensify, a new warning circulating among U.S. law enforcement has raised fresh questions about the evolving nature of modern warfare and whether the American homeland is truly prepared for it.

At the center of the concern is a chilling scenario: swarms of explosive drones launched from the ocean or even from beyond U.S. borders, quietly crossing into American airspace before striking population centers or infrastructure along the West Coast.

Federal authorities recently alerted police departments across California that Iran had allegedly considered launching a surprise drone attack from an unidentified vessel positioned off the U.S. coastline. The memo, reviewed by multiple media outlets, stated that Iranian forces may have aspired to carry out such a strike if the United States escalated military action against Tehran.

Although officials say the intelligence behind the warning remains unverified, the alert quickly drew attention from national security analysts and drone warfare experts. Some argue that the threat is real and growing, while others say the United States would likely intercept any such attack long before it reached American soil.

The debate reflects a deeper question about the future of warfare in the drone age and whether emerging technologies have made even powerful nations vulnerable in ways that once seemed unimaginable.

The FBI Alert That Triggered Concern

The initial alarm began with a bulletin circulated among law enforcement agencies in California in late February. According to the notice, investigators had received information suggesting that Iran had explored the possibility of launching unmanned aerial vehicles from a vessel off the U.S. coast.

The memo warned that these drones could potentially target unspecified locations in California if Washington carried out strikes against the Iranian regime. However, officials stressed that the information did not include specific details about timing, targets, or perpetrators.

Despite the uncertainty surrounding the intelligence, the alert was taken seriously enough to be distributed through the Joint Terrorism Task Force network, which shares security information between federal and local agencies.

Local authorities quickly responded with a cautious but measured tone. Police departments across Southern California said they were coordinating with federal partners and reviewing contingency plans while emphasizing that no immediate threat had been confirmed.

California Governor Gavin Newsom also sought to reassure residents that there was no imminent danger, even as state officials remained prepared for potential emergencies.

Still, the idea that foreign drones could reach the American mainland struck a nerve with security analysts who have long warned about vulnerabilities in U.S. airspace.

A Drone Expert Warns of a Dangerous Vulnerability

Among those raising concerns is Brett Velicovich, a former U.S. Army intelligence and special operations specialist who spent years using drones to track and eliminate leaders of extremist groups overseas.

Velicovich argues that the United States may be underestimating how easily adversaries could exploit drone technology to carry out attacks far from traditional battlefields.

In his view, the threat is not theoretical.

According to Velicovich, Iran possesses thousands of long-range drones capable of flying hundreds of miles while carrying explosive payloads. These systems can be preprogrammed using GPS coordinates, allowing them to strike targets with considerable precision once launched.

What makes the threat especially concerning, he says, is that the launch point does not need to be close to the target.

Drones could theoretically be launched from ships positioned offshore, from vessels disguised as commercial craft, or even from unmanned platforms controlled remotely from thousands of miles away. Modern satellite internet systems allow operators to guide these aircraft from remote locations, eliminating the need for human pilots anywhere near the launch site.

Velicovich believes such tactics are part of a broader strategy aimed at spreading fear and disruption rather than achieving traditional military objectives.

Possible targets, he says, could include large crowds, sporting events, hotels, office complexes, ports, military installations, or critical infrastructure such as power plants.

The goal would be psychological impact as much as physical damage.

Drone swarms, he warns, are designed to overwhelm defenses and create chaos.

The Reality of Modern Drone Warfare

The concerns about a potential drone attack on American soil are rooted in a larger shift taking place in global warfare.

Over the past decade, unmanned aerial systems have transformed conflicts from the Middle East to Eastern Europe. Cheap, mass-produced drones have proven capable of damaging tanks, ships, and infrastructure that once required expensive missiles or aircraft to destroy.

Iran has become one of the world’s leading producers of such systems.

Its Shahed-series drones, often described as “loitering munitions,” are essentially flying bombs that can travel long distances before diving into their targets. Some models are believed to carry explosive payloads of up to 50 kilograms and can cost as little as tens of thousands of dollars to manufacture.

Because these drones are relatively inexpensive, they can be launched in large numbers. When dozens or even hundreds are sent toward a target simultaneously, traditional air defense systems can struggle to keep up.

The war that erupted between the United States, Israel, and Iran in early 2026 has already demonstrated how heavily Tehran relies on these tactics.

Since the conflict began, Iran has fired hundreds of missiles and launched thousands of drones at U.S. and allied targets across the Middle East.

Many of these attacks have been intercepted, but the sheer volume illustrates how quickly modern battlefields can become saturated with unmanned weapons.

Security analysts say this same strategy could theoretically be adapted for attacks far beyond the Middle East.

Pentagon Says Iran’s Military Power is Collapsing

Despite warnings from some experts, U.S. defense officials argue that Iran’s ability to launch large-scale attacks is rapidly deteriorating.

At a recent Pentagon briefing, Secretary of War Pete Hegseth declared that American and allied strikes have dramatically reduced Iran’s military capabilities.

According to Hegseth, Iranian missile launches have dropped by roughly 90 percent, while suicide drone attacks have decreased by about 95 percent as U.S. forces systematically destroy launchers and production facilities.

He also claimed that the campaign has crippled Iran’s ability to manufacture new missiles and drones.

Factories, research centers, and weapons plants tied to ballistic missile production have been targeted across the country. The goal, Pentagon officials say, is not only to intercept existing weapons but also to eliminate Iran’s ability to rebuild its arsenal.

These statements are part of a broader narrative from the Trump administration that the war is being decisively won.

Military leaders say the United States now enjoys overwhelming air superiority and has destroyed dozens of Iranian ships while dismantling critical elements of the country’s military infrastructure.

From this perspective, the possibility of Iran launching a complex drone strike against the U.S. mainland appears increasingly unlikely.

Yet even some defense experts who believe the threat is limited still argue that the United States must prepare for worst-case scenarios.

Could a Drone Attack on California Actually Happen?

Opinions among specialists vary widely.

Some analysts believe the scenario described in the FBI memo would be extremely difficult for Iran to carry out successfully.

Launching drones from a vessel close enough to strike California would likely attract attention from U.S. naval patrols, radar systems, and satellite surveillance long before the drones reached their targets.

Jeff Thompson, the chief executive of drone technology company Red Cat, has suggested that such an operation would likely be detected and intercepted quickly.

According to Thompson, a launch from a small boat off the coast would be relatively easy to identify and destroy using existing defense systems.

However, he also warns that smaller drones present a different challenge.

Unlike larger military systems, many compact drones are built from commercially available components. These aircraft can fly low, move quickly, and evade traditional radar systems designed to track larger objects.

This creates a new category of threats that military planners are only beginning to address.

Future defense strategies may rely on large numbers of inexpensive counter-drones designed to intercept incoming aircraft automatically.

In other words, the next generation of warfare may involve machines battling machines.

The Broader Geopolitical Backdrop

The fears surrounding a potential drone attack cannot be separated from the larger conflict unfolding between the United States and Iran.

The war began after escalating tensions in the region led to direct military strikes by American and Israeli forces on Iranian facilities in late February 2026. Since then, the conflict has expanded across multiple fronts in the Middle East.

Iran has launched missile and drone attacks against U.S. positions in several countries, while American and allied forces have responded with widespread airstrikes targeting military infrastructure.

The fighting has already had global consequences.

Oil prices surged above $100 per barrel as shipping routes through the Strait of Hormuz were threatened, highlighting how quickly regional conflicts can ripple through the world economy.

Diplomatic efforts to contain the conflict have so far struggled to keep pace with the rapid escalation of military operations.

Meanwhile, intelligence agencies continue monitoring potential threats beyond the battlefield, including cyberattacks, sabotage operations, and the possibility of retaliatory strikes against Western targets.

The Growing Challenge of Defending the Homeland

For decades, U.S. homeland defense focused primarily on missiles, aircraft, and traditional forms of terrorism.

Drone warfare introduces a different type of challenge.

Unlike ballistic missiles, which follow predictable trajectories and require sophisticated launch infrastructure, drones can be launched from small platforms and flown at low altitude.

They can travel slowly, change direction, and blend into the clutter of civilian air traffic.

These characteristics make them difficult to detect using systems designed during earlier eras of warfare.

Some analysts worry that adversaries could exploit this gap.

Others argue that the United States still maintains overwhelming advantages in surveillance, intelligence, and air defense technology.

But the debate highlights an uncomfortable reality.

Modern technology has dramatically lowered the cost of launching aerial attacks, potentially allowing smaller actors to challenge even the most powerful militaries.

A Warning About the Future of Warfare

The FBI alert about a possible Iranian drone strike on California may ultimately prove to be nothing more than a precautionary notice based on incomplete intelligence.

Officials have repeatedly emphasized that the information behind the warning was unverified and that no credible threat has been identified.

Still, the conversation sparked by the memo reveals something larger.

Drone technology is spreading rapidly across the world, reshaping how wars are fought and how nations defend themselves.

What once required billion-dollar weapons systems can now sometimes be accomplished with devices that cost a fraction of that amount.

For countries like the United States, the challenge will be adapting defenses quickly enough to keep pace with these changes.

Whether the threat comes from a hostile nation, a terrorist organization, or even criminal networks, the age of unmanned warfare is already here.

The question now is how prepared the world’s most powerful countries truly are to face it.
