The D Brief: El Paso, explained; Navy ships collide; Marines’ aviation plan; Estonia’s warning; And a bit more.

Border patrol agents prompted the extraordinary U.S. airspace closure over El Paso Tuesday night and into Wednesday after using a high-powered laser to shoot down what was later revealed to be a party balloon that had drifted into the sky near the U.S.-Mexico border. 

Initially, Transportation Secretary Sean Duffy claimed the U.S. military was responsible and said the Federal Aviation Administration lifted its 10-day closure after “a cartel drone incursion” had been “neutralized.” That was far from the truth, as military and federal officials familiar with the incident later told media outlets. 

Customs and Border Protection used the directed-energy weapon “near Fort Bliss without coordinating with the FAA,” the Associated Press reported Wednesday. Pentagon chief Pete Hegseth loaned the weapon to Homeland Security officials for a 30-day period that began last month, Fox reported. On Tuesday, “CBP officials thought they were firing on a cartel drone…but it turned out to be a party balloon,” the New York Times reported. 

The incident occurred about a week before a planned meeting about the weapon’s safety. Some military officials reportedly believed “requirements governing the protection of certain facilities from unmanned aircraft had been met,” justifying the weapon’s use before it had been authorized by the FAA, according to CBS News. A meeting about the weapon’s safety was scheduled for Feb. 20, “but the Pentagon and DHS wanted to move forward more quickly, prompting the FAA to put the flight restrictions in place,” the Washington Post reported.

Drones can be “useful for pinpointing the location of US Border Patrol agents to assist the cartel in smuggling non-citizens across the border into the United States,” Ars Technica points out. However, nothing about alleged drone activity in this incident appears to have been out of the ordinary, Rep. Veronica Escobar, D-Texas, said at a news conference Wednesday. And that suggests it remains unclear whether the incident resulted from “genuine concern about air travelers, a show of force, a fit of pique, or something else,” as Eric Berger of Ars Technica writes.

Local reax: “This was a major and unnecessary disruption, one that has not occurred since 9/11,” El Paso Mayor Renard Johnson told reporters Wednesday. You cannot restrict airspace over a major city without coordinating with the city, the airport, the hospitals, the community leadership. That failure to communicate is unacceptable,” Johnson said. 

“We have never seen something quite this extreme,” El Paso City Rep. Chris Canales said Wednesday. “No one from the local government or the local military base received any advance notice more than a few minutes, nor did the mayor.”

On this day in 1988, Navy missile-cruiser USS Yorktown and the destroyer USS Caron were intentionally rammed and pushed by Soviet vessels in the Black Sea as the Soviets sought to push the American ships out of Soviet territorial waters and into international waters.

Around the Defense Department

Two U.S. Navy ships collided while attempting to refuel in the Caribbean Sea Thursday, the Wall Street Journal reports. The destroyer USS Truxtun was taking on fuel from the USNS Supply fast combat support ship, both part of the largest naval buildup in the region since the Cuban Missile crisis.

Two people were injured but they’re in stable condition, and both ships have moved on with their mission, officials said. The incident is under investigation.

Here’s an explainer video about the process of refueling at sea. 

A Marine who fell overboard in the Caribbean Sea has been declared dead after search-and-rescue efforts were unsuccessful, Military Times reported Thursday. His name is Lance Cpl. Chukwuemeka E. Oforah, 21, and he fell from the amphibious assault ship USS Iwo Jima on Feb. 7. He was assigned to the 3rd Battalion, 6th Marines, which is based out of Camp Lejeune, N.C.

Developing: The Navy is preparing to send a second aircraft carrier to the Middle East, the Journal reported separately on Wednesday. The USS Abraham Lincoln carrier strike group is already in the region amid renewed tensions with Iran. 

USS George H.W. Bush would likely be called for the job, though the call may not come for two weeks. The carrier and its crew are currently conducting “a series of training exercises off the coast of Virginia, and it could potentially expedite those exercises,” U.S. officials said.  

“We have plenty of time,” Trump told reporters Friday. “If you remember Venezuela, we waited around for a while. And we’re in no rush. We have very good talks going with Iran.”

That’s not what he was saying last month. “Time is running out, it is truly of the essence!” the president posted in January. Why the turnaround? Nancy A. Youssef and Vivian Salama of The Atlantic explain how threats turned into talks, here.

Marines will use Air Force-tailored drone to help develop its robot wingman. General Atomics’ YFQ-42A will be used as a testbed for CCA concepts and gear, the company said on Tuesday. The work is part of the 

Marine Corps Air-Ground Task Force Uncrewed Expeditionary Tactical Aircraft effort. Defense One’s Thomas Novelly has a bit more about that, here.

MUX TACAIR is one of the top priorities of the 2026 Marine Aviation Plan, also released on Tuesday. FYI: “Central to the AVPLAN is the active integration of AI/ML as a primary modernization effort,” a USMC press release says.

Russia still sees the U.S. as its top adversary, Estonian intelligence report says. Recent U.S.-Russian talks about ending Moscow’s war on Ukraine should not be taken as a sign that Russia poses less of a threat to the United States and Europe, according to a new report from Estonia’s foreign-intelligence agency. “Despite this illusory thaw, Russia continues to regard the U.S. as its principal global adversary,” says the report, which was released Tuesday. 

Russian leader Vladimir Putin intends such talks to benefit him in two ways, it says: “First, by binding U.S. and Russian interests more closely together; second, by widening what Moscow perceives as existing rifts between the U.S. and Europe.” Defense One’s Patrick Tucker has more, here.

Developing: NATO launched a series of new exercises in the Arctic this week, the alliance said in a statement on Wednesday: “These activities include, among others, Denmark’s Arctic Endurance, a series of multi-domain exercises designed to enhance Allied ability to operate in the region, and Norway’s upcoming exercise Cold Response, where troops from across the Alliance have already begun to arrive.”

The drills come just weeks after Trump threatened to seize Greenland ahead of a speech before Europeans at the World Economic Forum in Davos, Switzerland. Trump later said he wouldn’t use military force to achieve that goal, but he has since posted on social media that he still aims to make Canada and Greenland U.S. territories. Since his speech at Davos, both Canada and France have opened consulates in Greenland.
