On 21 June, the Chinese Academy of Sciences hailed a breakthrough – a major upgrade to a kind of quantum device that measures magnetic fields. Magnetometers have been used to detect submarines since ...

Here’s What You Need To Remember: In 2018, Chinese scientists said they were developing a laser-equipped satellite that could detect submarines. The idea is to use laser beams of various colors that ...

China is making great efforts to detect U.S. submarines. Scientists at a Chinese research institute say they developed an airborne laser that might eventually detect hostile subs even at great depths.

Lockheed Martin in Owego has received an $18.8 million contract from the U.S. Navy. The contract includes the procurement of 25 Digital Magnetic Anomaly Detection hardware kits and associated program ...

The Debye effect could be used hunt submarines using the magnetic signatures of their wakes. Seawater is salty, full of ions of sodium and chlorine. Because those ions have different masses, any nudge ...

WASHINGTON, January 21, 2020 -- Most traditional electromagnetic methods for detecting hidden metal objects involve systems that are heavy, bulky and require lots of electricity. Recent studies have ...

DIU expands its Transition of Quantum Sensing (TQS) program to explore SandboxAQ's AQNav magnetic navigation software for U.S. and allied defense use-cases PALO ALTO, Calif., Nov. 18, 2025 /PRNewswire ...

GeoAcoustics Ltd and Ocean Floor Geophysics (OFG) have joined forces to develop a combined side scan sonar and magnetometer system as a single towfish.

Lockheed Martin Corp.’s LMT business unit, Rotary and Missions Systems, recently secured a $28.5 million contract for Phase I integration of the Digital Magnetic Anomaly Detection sensor into the ...

A startup company called SBQuantum (SBQ) is attempting to revolutionise navigation in locations where GPS is unavailable. The business creates and markets diamond-based quantum magnetometers for ...

Recent studies have shown metallic objects have their own magnetic fingerprints based on size, shape and physical composition. Scientists look to leverage these observations to potentially create a ...
