An 8x8 heavy truck-mounted phased array radar stands silently in the wilderness, yet it locks onto the flight path of a U.S. F-35 stealth fighter at 400 kilometers away.

In the general perception, China's detection of stealth aircraft relies on large fixed-meter-wave radar stations. This perception has been completely broken by the 610B mobile phased array air defense and anti-missile early warning radar developed by the 14th Research Institute of China Electronics Technology Group Corporation.

This radar not only possesses strong battlefield mobility but can also accurately lock onto an F-35 stealth fighter at 400 kilometers, marking that China's anti-stealth capabilities have now ranked among the world's best.

Firstly, a major technological breakthrough: S/L composite band overcomes the stealth problem. The domestically produced 610B air defense radar is a fourth-generation air defense and anti-missile early warning radar, and its core technological breakthrough lies in the adoption of an S/L composite band design.

This design cleverly balances the dual needs of anti-stealth and accurate positioning: the L-band fully utilizes its anti-stealth characteristics, while the S-band significantly improves target resolution and positioning accuracy.

The radar is estimated to be equipped with 7,616 gallium nitride array elements, with a radar aperture of 48-62 square meters. Its powerful hardware foundation enables reliable detection and tracking of stealth targets such as the F-35 at 400 kilometers away.

Compared with traditional meter-wave radars, the 610B not only solves the problem of insufficient positioning accuracy, but also extends the anti-stealth detection from fixed positions to mobile deployment, achieving a qualitative technical leap.

The deployment of this radar proves the "unidirectional transparency" in the U.S.-China stealth confrontation.

The emergence of the 610B radar has created a significant imbalance in the U.S.-China strategic situation. The stealth fighter advantage built with trillions of dollars by the United States is gradually becoming ineffective in front of China's anti-stealth system, while the United States itself lacks effective means to counter China's stealth platforms.

This situation has formed a "unidirectional transparency" strategic dilemma: for the U.S., the stealth platforms such as the F-35 and F-22, which the U.S. military relies on, are gradually "visible" in front of China's complete anti-stealth network, greatly weakening their penetration strike capability; for China, the stealth fighters such as the J-20 and J-35 can still maintain their stealth advantages when facing the U.S. forces, forming a non-symmetrical situation where "I can hit you, but you cannot hit me."

The U.S. military has not yet deployed radar systems of the same level. The AN/SPY1D radar of the "Aegis" system mainly targets conventional aircraft, and its ability to detect stealth targets is limited. This technological gap makes the U.S. military face serious threats from stealth platforms in the Asia-Pacific region.

The functions of the 610B radar go far beyond anti-stealth. It is a true multi-functional early warning system, whose main functions include: long-range early warning detection: specifically targeting airborne targets such as stealth aircraft, with an effective detection range of 400 kilometers; multi-target identification: capable of identifying tactical ballistic missiles and near-space targets simultaneously, effectively countering fourth-generation missile threats; high-precision tracking: thanks to a narrow beam width and advanced signal processing technology, its angle measurement accuracy even exceeds that of the AN/SPY1D radar used in the U.S. "Aegis" system.

This comprehensive capability allows the 610B to provide high-precision target information for subsequent interception systems, forming a complete "detection-tracking-interception" chain.

One of the most remarkable features of the 610B radar is its high degree of mobility. It is installed on an 8x8 North Industry Beibei heavy truck model 4038A chassis, possessing rapid tactical mobility.

This design brings revolutionary battlefield advantages: quick deployment and withdrawal: it can rapidly set up operations in different regions, greatly enhancing battlefield survivability. Flexible adaptation to various environments: it can move with combat units, adapting to complex and changing operational environments; concealment and surprise: the mobile deployment capability makes it difficult for opponents to pre-position and suppress radar positions.

As a digital array radar, the 610B has a very strong anti-jamming capability. In the modern complex electromagnetic environment, it can effectively resist enemy electromagnetic interference, ensuring the stable operation and accurate detection of the radar system. This characteristic is particularly important in the modern electronic warfare environment, ensuring that even under strong electromagnetic interference conditions, the radar can maintain continuous control of the battlefield airspace.

The competitive situation between the U.S. and China in the field of stealth technology has become clear: U.S. stealth fighters are gradually losing their mystique in front of China's complete anti-stealth system, while the U.S. itself lacks effective means to counter China's stealth platforms. This "unidirectional transparency" has created a significant strategic imbalance - the stealth advantage built by the U.S. military with trillions of dollars is effectively restrained, while China's stealth aircraft fleet can freely move in the sub-space domain.

The appearance of the 610B radar not only proves the maturity of China's anti-stealth technology, but also reveals a deeper fact: in the strategic game of stealth and anti-stealth, the balance has undergone a fundamental shift. For Chinese defense industry, detecting the F-35 has become simple, while for the U.S. military, dealing with China's stealth threat remains difficult.
