In early October 2025, the Venezuelan military revealed in a public statement a rare operation: it successfully locked five U.S. F-35s in the airspace bordering the Caribbean Sea.
Although these fighter planes did not enter Venezuelan airspace, their air activities 75 kilometers away from the coastline have already aroused the high vigilance of the local air defense system.
Surprisingly, this lock-up did not rely on traditional radar, but was completed by a set of anti-stealth radars originating in China.
This incident quickly sparked heated discussions in the international military circle, because it directly hit the weakness of stealth technology that the US military is proud of, and also caused the outside world to re-examine the concept of "invincible stealth fighters."
China radar "sees through" stealth technology in the Caribbean
The radar model used to detect the F-35 is the JY-27A, which is not a new face.In 2020, Venezuela used the system to detect and track a US F-22 fighter aircraft.
On the other hand, this time the target was replaced with the F-35, and it locked five aircraft at the same time.
JY-27A is a long-range early warning radar. Its outstanding feature is that it works in the ultra-high frequency band and can detect targets that are "stealthy" to conventional radars.Simply put, the F-35 was originally designed to avoid high-frequency radar detection as much as possible, but its protection against the ultra-high-frequency band is weak.
And the JY-27A is using this shortboard for the detection. Combined with other models of medium- and short-range radar systems, Venezuela has formed a relatively complete defense network.This "networking" method does not rely on a single device, but improves the overall detection and response capabilities through the information exchange of multiple radar systems.
From the operator’s point of view, this “confrontation” is not surprising. The radar system captured the target in normal operation and did not use missiles or aircraft to intercept it as in traditional combat.
But this does not mean that it is of little significance. In fact, this static locking capability itself poses a substantial threat to stealth fighters. Because once the fighter plane is exposed, the next step may mean being accurately guided to attack.
F-35 "stealth" is no longer stable, and the US military's tactical thinking may need to be adjusted
The F-35 has long been regarded as the core aircraft of the US military's air combat, emphasizing its advantage of "if you can't see it, you can't fight it".But from the actual performance of the last few years, this technology is no longer as helpless as it used to be.
In addition to the Venezuelan lockdown, there have been records in the Middle East and Asia-Pacific over the past few years of U.S. hidden fighter jets discovered by non-allied countries’ radars.
One is that the F-35’s hidden design relies too much on material technologies, such as special coatings and body structures.Although these designs did lead the way in the early stages of research and development, these original advantages are being eroded as radar technology in other countries advances, especially in-depth research into low-frequency bands.
In addition, the F-35 itself has also exposed many technical problems, such as the flight control system is often not updated in a timely manner, and the stealth layer of some fighter jets shows signs of aging in high temperature and high humidity environments, which has reduced its performance in complex climates.
More importantly, the U.S. military often shows excessive confidence in tactical arrangements when using the F-35. Knowing that Venezuela has deployed radar systems with anti-hidden capabilities, and still arranging combat aircraft near-range activities, is undoubtedly a risk test.
This shows that the U.S. high-level officials still underestimate the opponent's air defense level, and may also be deliberately exploring and testing the opponent's response speed and technical maturity.
From a wider perspective, this strategy does not actually appear for the first time. In the first half of this year, the U.S. military has repeatedly imposed compulsory measures on Venezuelan fishing vessels in international waters in the Caribbean Sea on the basis of "anti-drug smuggling".
According to public reports, at least five Venezuelan fishing boats have been intercepted or even sunk in the past five months. Combined with the appearance of the F-35 in nearby airspace this time, it is difficult not to doubt whether the United States has deeper strategic intentions behind it.
The Latin American attitude is changing, and the technical balance is silent.
Although this incident occurred within Venezuela's own air defense system, it attracted widespread attention throughout Latin America.Colombia and Bolivia have criticized the U.S. military presence in the Caribbean.
Although the rhetoric is not too fierce, such public statements are uncommon in the relatively silent situation in Latin America in the past.
Brazil and Mexico have been more cautious, but have also expressed concerns about the regional security situation in media reports and diplomatic statements.This change shows that Latin American countries have begun to become discontented or even alert about the way the U.S. military continues to intensify its military intervention.
At the same time, the global layout of Chinese-made radar equipment is quietly expanding. In the past few years, many countries including Syria, Pakistan, Egypt and other countries have successively introduced similar types of radar systems.
What they have in common is that they do not have a large-scale air force, but they hope to improve the sense of airspace security through technical means.The price of such radar systems is relatively controllable, and the cost of operating maintenance is also low, becoming a real choice for many small and medium-sized countries in the face of high-end fighter aircraft threats.
What is reflected behind this is a change in the balance of technology. Hidden technology was once a patent of a few countries, and now anti-hidden capabilities are also spreading.It doesn’t necessarily change the pattern of the battlefield completely, but it’s enough to allow the strong powers to repeatedly weigh before launching high-end fighters, especially in sensitive areas.
“Transparent battlefields” are emerging, new rules are quietly generated
The fact that the F-35 is locked is not just a technical demonstration, but also a manifestation of a trend.The battlefield has become more and more "transparent", and it is no longer possible to maintain an advantage through single stealth. The future combat environment will rely more on system collaboration, multi-platform linkage and information integration.
Taking the incident as an example, Venezuela did not respond by missiles or fighter jets, but by radar detection to identify and track targets, indicating that modern defense is no longer the number of weapons, but the ability to control information.
Whoever can discover each other earlier will be able to decide faster whether to make the next move. Under this logic, stealth fighters are important, but they are no longer absolute "passes".
For small nations, the changes brought by this technological downturn are far-reaching. Even if the military is not strong, it can also improve its air defense capabilities through the introduction of advanced early warning systems, delaying or even defeating potential threats.
For the big powers, it is necessary to rethink their strategic deployment, especially in regions such as Africa, Latin America and the Middle East.In the past, the way of relying on technological advantages for "low-cost intervention" is being challenged.
The opponent does not have to have warplanes, but as long as they can see you, it is already a deterrent.
The F-35 is locked, not the beginning of the battle, but a cognitive adjustment.It reminds people that war is not always hard-to-hard, information and perception are the real first line of defense.
From a radar wave in the Caribbean to the rearrangement of global multipolar forces, whoever can see each other first can rewrite the situation first. Technology is not always ahead, and the rules are never set in stone.
The real competition is never just a superficial flight trajectory, but quietly unfolding between visible and invisible.
