The FBI's second-in-command says the bureau's biggest near-term security concern is not a coordinated mass attack on the scale of September 11. It is a single person with an inexpensive drone, an explosive payload, and a cellular connection that lets them pilot the weapon from thousands of miles away.
FBI Deputy Director Chris Raia told Fox News Digital in an exclusive interview that armed drone tactics already deployed on battlefields in Ukraine and the Middle East will inevitably migrate to American cities. His warning landed alongside newly unsealed court records that suggest an alleged domestic conspiracy involving explosive-laden drones may have extended beyond its original target to a FIFA World Cup match in Kansas City, Missouri.
The combination, a senior FBI official publicly naming drones as the top threat vector, a live domestic conspiracy case expanding in scope, and a technology curve that favors attackers over defenders, paints a picture that should concern every American who lives near a stadium, a public gathering, or a critical piece of infrastructure.
Raia did not mince words about where the danger sits on the FBI's priority list. In his interview, he described the drone threat as immediate and personal, not the province of state-sponsored terror networks but of lone actors with off-the-shelf hardware.
"I think the biggest threat right now, kind of the five-yard target, if you will, is going to be that threat from a drone."
He drew a sharp contrast with the large-scale, multi-actor plots that dominated counterterrorism thinking for two decades after 2001.
"I'm less concerned about a mass 9/11-style attack than I am a lone single person, a single attacker."
That shift in threat calculus reflects what military observers have watched unfold overseas. In Ukraine, commercially available drones costing a few hundred dollars have destroyed armored vehicles worth millions. In the Middle East, armed groups have used similar platforms to strike both military and civilian targets. Raia acknowledged that those lessons have not been lost on people who wish Americans harm.
"We have seen that overseas, and it's only a matter of time before somebody brings that type of attack, that threat vector here to the United States."
What makes the next generation of the threat qualitatively different, Raia explained, is the shift from short-range radio-frequency and Wi-Fi drone links to 5G and LTE cellular network connections. Traditional hobby drones operate within line-of-sight or a limited wireless range. A drone connected to a cellular network can be piloted from anywhere with a data signal.
Raia put the implication in blunt geographic terms.
"That means somebody in China can control a drone over New Orleans."
The statement is not hypothetical futurism. It describes a capability that already exists in the commercial drone market. And it creates a nightmare for law enforcement agencies accustomed to building cases around physical proximity, placing a suspect near the scene of a crime. When the operator sits on a different continent, the investigative model changes fundamentally.
As the FBI works to restructure its operations under new leadership, Director Kash Patel has announced a generational overhaul shifting 1,000 agents to field offices, the drone threat adds another layer of urgency to the question of where the bureau's resources should be aimed.
Raia was unusually candid about a significant hole in the FBI's intelligence-gathering capability. Encrypted messaging platforms, the kind used by millions of ordinary people every day, also provide cover for those planning attacks. The deputy director did not name specific platforms in the interview, but court records in the related conspiracy case reference Signal, an end-to-end encrypted messaging app.
"That is a gap for us in encrypted communications platforms."
He went further, conceding that the FBI cannot monitor every encrypted conversation where threats might be discussed.
"I think I would be foolish to think that we're in every single one of those rooms."
To compensate, Raia said the bureau relies on a combination of confidential human sources, undercover operatives, and tips from the public. He singled out the drone hobbyist community as a valuable set of eyes, noting that experienced recreational flyers are often better positioned than federal agents to spot something out of the ordinary.
"Especially all these drone hobbyists out there that are flying drones for non-nefarious purposes, they know better what somebody out of the ordinary looks like than we do."
Raia's warnings are not abstract. They sit against the backdrop of an active federal prosecution that the FBI has described as the alleged plot to use explosive-laden drones at a White House UFC event. Court records allege that members of the conspiracy discussed deploying weaponized drones to trigger a mass evacuation.
The case originated, Raia revealed, from one of the most old-fashioned investigative tools imaginable: a concerned parent.
"We had a concerned parent that really launched this entire UFC 250 case off."
That parent was the mother of Tycen Proper, a named suspect in the case. After she flagged her son's online activity to investigators, the FBI obtained a warrant for Proper's phone. What agents found, federal prosecutors allege, was a primary Signal chat with approximately 19 participants, along with smaller operational chats organized by role and location.
A newly charged defendant in the case allegedly exchanged messages about acquiring drones, payloads, and specialized equipment for the operation. The full scope of the alleged plot, including specific charges, the identities of all participants, and the case's docket number, remains partially under seal.
The disclosure of the case itself became a point of friction between federal agencies. The FBI director's public discussion of the sealed case drew a sharp rebuke from the Secret Service, raising questions about interagency coordination on sensitive national security matters.
The newly unsealed court records added another dimension to the case. An FBI agent wrote in an affidavit that he believed messages exchanged among the alleged conspirators referenced preparations for travel to Missouri, suggesting investigators were examining whether the group discussed targeting a FIFA World Cup match scheduled for July 3 in Kansas City.
The FIFA World Cup security operation itself has been one of the largest domestic security efforts in recent U.S. history. Raia told Fox News Digital that agents seized more than 300 drones and made eight arrests tied to unauthorized drone activity during the tournament. Whether those arrests resulted in criminal charges or were administrative in nature was not specified.
The scale of the seizures alone tells a story. Three hundred drones confiscated during a single sporting event suggests the airspace above major public gatherings is far more crowded, and far harder to secure, than most Americans realize.
The drone threat is not limited to one ideological camp or one type of actor. Earlier this year, federal authorities arrested three men in an alleged ISIS-inspired plot to target U.S. Special Forces with drones and grenades, underscoring how widely the tactic has spread among those who seek to do harm on American soil.
Raia's assessment was reinforced by former FBI Deputy Director Dan Bongino, who issued his own warning to Fox News on June 16. Bongino emphasized how rapidly the commercial drone market is outpacing traditional security assumptions.
"This technology is evolving on probably weekly, if not monthly cycles now. And don't think that people looking to commit malicious acts, terrorists and others, haven't picked up on this. It's cheap. It's very difficult to defeat."
Cheap and difficult to defeat. That two-word combination is the core of the problem. A consumer drone capable of carrying a small payload can be purchased for a few hundred dollars. The countermeasures needed to detect, track, and neutralize such a device in a crowded urban environment cost orders of magnitude more, and raise their own legal and logistical complications.
The FBI has reportedly begun building counter-drone capabilities, including a national counter-UAS training center. But the gap between the speed of commercial drone innovation and the pace of government procurement is a familiar one. It is the same gap that has defined nearly every asymmetric threat the country has faced since the turn of the century.
Several significant questions remain open. The full roster of defendants in the alleged UFC conspiracy has not been publicly identified. The specific charges against Tycen Proper and others have not been detailed in available court filings. The identity of the FBI agent who authored the affidavit linking the conspiracy to the Kansas City FIFA match has not been disclosed.
Perhaps most critically, the FBI has not publicly described what specific counter-drone technologies or protocols it has deployed, or plans to deploy, to protect major events and critical infrastructure. Raia's interview was candid about the threat. It was far less specific about the response.
That asymmetry, detailed about the danger, vague about the defense, is itself a data point. It suggests the bureau knows the problem is outrunning the solution.
When the FBI's own deputy director says a domestic drone attack is not a question of "if" but "when," the only responsible question left is whether the people in charge are moving fast enough to narrow the window. The battlefield overseas has already answered what happens when they don't.
