The Wall Street Journal has reported mysterious UAVs spotted surveilling some of America’s most sensitive military sites, leaving the Pentagon struggling to respond. These unidentified UAVs have been seen flying over military installations in Virginia and Nevada throughout the past year, including the secret base of the Navy’s elite SEAL Team Six and Naval Station Norfolk, recognized as the world’s largest naval port.
Former U.S. Air Force Gen. Mark Kelly told The Wall Street Journal he first became aware of mysterious UAV sightings in December 2023, when officials at Langley Air Force Base in Virginia reported seeing dozens of UAVs flying over the base at night.
The source of these UAVs remains unknown, leaving officials puzzled about whether they were operated by sophisticated hobbyists or potentially by Russia or China. The complexity and coordination of the flights suggested a level of sophistication beyond civilian drone operations, according to the report.
The U.S. military faced significant challenges in addressing this threat. Federal law restricts the military’s ability to shoot down UAVs over bases unless they pose an immediate threat. Aerial snooping does not qualify as a threat, though some lawmakers hope to give the military greater leeway to address these challenges in the future.
The sightings ended on Dec.23, 2023, with authorities still unsure of the UAVs’ origin or who controlled them. However, a clue emerged in January 2024 when a Chinese student named Fengyun Shi, studying at the University of Minnesota, was caught flying a UAV near Langley Air Force Base. Shi’s UAV got stuck in a tree, which he abandoned before flying to California. The FBI retrieved the drone, discovering it had taken photos of Navy ships docked at the base, which led to Shi being sentenced to six months in federal prison.
In October 2024, U.S. officials confirmed that similar drone swarms had been observed near Edwards Air Force Base in Nevada. The Department of Defense (DOD) has not publicly identified the source behind these surveillance drones.
In response to these incidents and potential threats, Langley Air Force Base is exploring new measures to safeguard its airspace. The base’s 633rd Contracting Squadron issued a notice seeking proposals for installing anti-drone nets around sunshades used for aircraft, including F-22s. These nets are designed to disable small UAVs while allowing quick retraction to ensure flight operations remain unaffected. The proposed system would withstand extreme weather conditions and prevent drones from interfering with aircraft or personnel.

The U.S. Department of Defense has called for thousands of UAVs to be built as a part of its Replicator initiative that aims to hasten military innovation to “leverage platforms that are small, smart, cheap and many,” said Deputy Defense Secretary Kathleen Hicks in a recent speech. This was cited in a Wall Street Journal editorial published on Sept. 13.
The United States plans to build thousands of UAVs over a 24-month period to counter China and the current military threat against U.S. forces in the Pacific Ocean. The UAV swarms could help the United States jam or distract enemy radars and surface-to-air missiles to stop China from pushing U.S. forces out of the Pacific.
The Wall Street Journal article stated that this idea by the Pentagon is not a real substitute for a bigger navy. While the Pentagon’s idea of UAV swarms for reconnaissance in the Pacific is technologically innovative, the article stated that the United States will still need technology breakthroughs and plentiful stocks of materials ranging from aircraft to munitions.
Furthermore, Deputy Hicks said that the Replicator initiative is not asking for new money in the next fiscal year budget, citing “not all problems need new money; we are problem-solvers, and we intend to self-solve,” reported the Wall Street Journal.
A new swarm of UAVs will give significant support to the U.S. military to counter China. However, the Pentagon’s quick plan for an unmanned technological “revolution” will need more investment to compensate for the failures that will inevitably accompany the new technology, the editorial argued, and to build “two Virginia-class submarines a year and fielding thousands of long-range weapons so U.S. forces don’t run out of their best firepower after a week in the Taiwan Strait.”.
Feb. 4 saw the news networks alive with sometimes wild reports about UFOs, UAVs and then a balloon. Balloons are used for weather forecasting on a regular basis, launched daily into the stratosphere with payloads gathering wind speed and direction, temperature, humidity, pressure and, of course, position.
Synchronized twice a day at about 900 locations around the world, balloons are released into the stratosphere gathering essential atmospheric data to feed our weather forecasts. Reaching altitudes of 20 miles, these balloons often drift on winds as far as 125 miles from the release point, broadcasting measurements from their onboard sensors.
At first, maybe North American Aerospace Defense Command (NORAD) thought the balloon crossing into Alaska’s airspace was just one of these high-altitude weather prediction vehicles. Aircraft were apparently scrambled, and initially it was decided there was no threat, so the balloon was allowed to continue and enter Alaskan airspace. It was detected and subsequently tracked by both the United States and Canada for some time as it continued to drift on the jet stream over the border into the lower 48. Then, people in and around Billings Montana (home to one of the nation’s three nuclear missile silo fields at Malmstrom Air Force Base) started to send in reports of a very large balloon high overhead — according to one observer with a high-resolution camera, it even seemed to be stationary for 35 minutes.
Apparently, by the time the good folks in Montana were looking up, the Pentagon had decided the balloon was a Chinese surveillance vehicle. To get this detail, one or more U-2 high altitude reconnaissance aircraft had been dispatched to investigate. The collected U-2 information spotted markings of a Chinese manufacturer on the 200-foot-tall balloon. A payload the size of a small passenger jet dangled some 20 feet below the balloon canopy. It had several antennas of various configurations. A huge solar panel was attached — presumably to power its suite of surveillance sensors.
The Federal Aviation Administration (FAA) ordered a ground stop for all aircraft traffic at the Billings airport while decisions were made about downing the balloon or allowing it to proceed.
Meanwhile, it may seem obvious that both the United States and China have developed, launched and make use of surveillance satellites. I imagined that a couple of dozen of these space vehicles would be buzzing over not only each other’s landmass, but also surveilling dozens of other countries as they orbit the whole planet.
What I found was a report that China had at least 260 such orbital observation platforms in 2022, and the United States has even more. Isn’t that enough without resorting to lower-tech balloons?
It’s possible that some electronic transmissions are short range and would not be detected by surveillance satellites operating in geosynchronous orbit (22,000 miles out), or even at 300 miles where the International Space Station (ISS) and most surveillance satellites hang out. So, a slow-moving balloon at 20 miles up might be ideal to “sniff” ground transmissions from sensitive military installations, and if you could control the balloon to hover, all the better to pick up radio signals. Could the gathering of transmission data somehow be used to geo-locate the source? It’s something the U.S. military may be working on, too, as it is reportedly also building a fleet of autonomous dirigibles and balloons.
According to press reports, the United States decided not to immediately take down the balloon, even though it subsequently discovered its surveillance capabilities. Not only was there concern over debris falling on populated areas but allowing the balloon to continue its flight over the United States provided an opportunity to observe its behavior and gather useful information. U.S. bases along its path apparently shut down all communications in sequence, as the balloon passed overhead.
The balloon was apparently found to be transmitting – presumably reporting on where it was and what it had detected. But, at some time transmissions ceased, possibly when U.S. Air Force activity was detected nearby.
The take-down off Myrtle Beach
An F-22 flew to almost the same altitude as the balloon and fired an AIM-9X Sidewinder missile into it, leaving the payload to tumble from 60,000 feet into the shallow (50-foot deep) Atlantic Ocean off Myrtle Beach, South Carolina. Recovery boats were already on hand to pick up the collapsed canopy, and to begin locating the electronics payload on the seabed. At time of writing, the U.S. recovery effort has yet to inform us on finding the key electronic payload, which would go a long way to confirming the intended mission for the balloon.

Strange, but a couple of days later over Canada, F-22s were again in action to take down a “cylindrical object” detected at 40,000 feet — an altitude posing a danger to airline traffic. Little has been released on what this object might have been — could it possibly be a re-entering piece of space debris? Again, debris recovery and analysis is underway, and we patiently wait for a public report about what this was all about.
What have we learned?
Both China and the United States operate huge fleets of surveillance satellites gathering intelligence daily about each other’s capabilities and those of other countries. Both China and United States have also invested in surveillance balloons, but China is the only country to send one over U.S. territory.
There may have been earlier balloon incursions, which are only now being reported. The U.S. response was initially to determine the configuration of the balloon and its payload, then to allow its journey along the jet stream to continue. The United States has said the balloon did not uncover anything already available by other means, but recovery and analysis of the payload would presumably confirm this announcement.
China is not happy about the U.S. takedown of a harmless, stray weather balloon. And what the heck were F-22s shooting at in Canada?
We’ll tell you more when we learn more….

Editor’s Note: Since the initial instance of an unidentified object floating across U.S. airspace — later identified as a Chinese surveillance balloon — three additional unidentified aerial objects were spotted in North American airspace. One was spotted in Alaska, one in northern Canada and one over the Great Lakes region. All three were shot down by U.S. fighter jets out of caution.
A bill moving through the U.S. Congress would impose a five-year ban on United States government purchases of drones manufactured or assembled in China, reports The Associated Press. The measure reflects bipartisan concerns that the unmanned aerial vehicles (UAVs) made in China could facilitate Chinese spying on critical infrastructure.
Major commercial and consumer UAV-maker company DJI is based in Shenzhen, China. Many of its small, low-altitude drones are employed by local and regional government users in law enforcement, emergency response and surveying. The ban could affect police departments that rely on federal funds for equipment. In 2020, the Department of Homeland Security halted such grants for Chinese-made drones.
Chinese-made components, including GNSS receivers and inertial sensors, are not addressed in the bill, and the Pentagon has acknowledged that many components for non-Chinese-company drones are made in China.
While the ban wouldn’t go into effect until 2023, many federal agencies have already imposed temporary restrictions on the use of Chinese drones. The Interior Department had flown more than 11,000 drone missions before January, when the agency temporarily grounded its fleet of more than 500 DJI drones over cybersecurity concerns, according to The Hill. The Hill cites a May 6 Pentagon report. The report found no malicious code in the software for DJI’s Government Edition drones.
An analysis by Booz Allen Hamilton released in June 2020 found no evidence that DJI drones have shared sensitive information with the company or the Chinese Communist Party.
In August 2020, the Defense Department issued approval to drones from five companies:
Skydio’s X2-D. Skydio is based in Redwood City, California.
Parrot’s Anafi USA. While Parrot is based in Paris, France, the ANAFI USA drone is manufactured in the United States for U.S. customers.
Teledyne FLIR’s Flir M440 Ion. The drone was originally made by Altavian in Florida, which was acquired by FLIR in December 2020, which was subsequently acquired by Teledyne Technologies in January. Teledyne FLIR is headquartered in Wilsonville, Oregon.
Teal Drones’ Golden Eagle. Teal Drones is based in Salt Lake City, Utah.
Vantage Robotics’ Vesper. Vantage is based in San Leandro, California.

Starting this month, the inspector general for the U.S. Pentagon will be reviewing how SpaceX’s rockets became certified to launch payloads for the U.S. Air Force, a decision made in May 2015.
“Our objective is to determine whether the U.S. Air Force complied with the Launch Services New Entrant Certification Guide when certifying the launch system design for the Evolved Expendable Launch Vehicle-class SpaceX Falcon 9 and Falcon Heavy launch vehicles,” wrote Michael J. Roark, deputy inspector general for Intelligence and Special Program Assessments, in a Feb. 11 memorandum to the Air Force.
In April 2016, the U.S. Air Force awarded SpaceX the first competitively sourced National Security Space (NSS) launch services contract in more than a decade, when the company won the GPS III Launch Services contract, fixed at $82,700,000.
Less than one year later, SpaceX was awarded a second contract for launch services to deliver a GPS III satellite to its intended orbit.
The evaluation will be performed at the Space and Missile Systems Center, a unit of Air Force Space Command, headquartered at Los Angeles Air Force Base in El Segundo, California. Additional locations may also be identified as part of the audit.
