Chinese Kalmaras Pose New Threat to Submarines

Chinese scientists have made significant progress in submarine detection, creating a cheaper and more sensitive version of the superconducting quantum interference detector (SQUID). Last year, a research was published which opens up a new era in submarine detection technology.

SQUID, which is used to measure extremely weak magnetic fields, finds applications in physical research, medical diagnostics, and submarine detection technologies. These devices work on the principle of superconductivity and typically require low temperatures for zero electrical resistance.

A team of researchers led by Zhang Inji has developed a simplified design using only one superconducting magnetic gradiometer instead of six, greatly increasing accuracy. Previously, expensive SQUIDs were only available to powerful military fleets and were mainly used in specialized anti-submarine aircraft. Now, this technology can become more affordable and can be used in unmanned aerial vehicles.

The improved detectors now require only one part instead of six, reducing interference and increasing sensitivity by ten times. Tests have demonstrated that the improved detectors perform well and effectively apply the new method.

A study published in the Chinese journal “Cryogenic and Superconductivity” shows that the device remains stable even in challenging conditions and is capable of identifying extremely weak magnetic anomalies.

This breakthrough has the potential to change global military dynamics by giving China an advantage, particularly in confronting advanced US submarines, and influencing situations in regions such as the South China Sea.

This technology, developed by American scientists in 1964, was initially used in military aircraft but faced challenges in tracking moving submarines. German researchers made significant contributions to the development of this concept. Now, China aims to become a leader in this field by investing substantial funds in the technology.

The potential military application suggests the implementation of this technology by the Chinese army, further strengthening their capabilities.
