MITCHEL FIELD, N.Y., March 27, 2025 -- Frequency Electronics, Inc. (“FEI” or the “Company”) (NASDAQ-FEIM), a leading provider of precision timing and frequency technology, today announced it has been awarded a subcontract from Leidos to develop a next-generation Nitrogen Vacancy (NV) Diamond Magnetometer.

The award supports the development of a compact, highly sensitive quantum magnetometer leveraging nitrogen vacancy centers in diamond to detect magnetic fields for magnetic navigation. The system is needed for alternative position, navigation in GPS denied and degraded environments. The NV Diamond magnetometer is very well suited for deployment in challenging operational environments where traditional sensing technologies are limited.

Dr. Thomas McClelland, President and CEO at Frequency Electronics said, “Quantum sensing is at the frontier of modern physics and defense technology. This subcontract reflects the growing demand for highly sensitive, reliable, and compact magnetic field sensors across defense, intelligence, and scientific applications. We are proud to collaborate with Leidos and MIT-Lincoln Labs in pushing the boundaries of quantum magnetometry.”

The NV Diamond magnetometer will build upon Frequency Electronics' legacy of delivering advanced frequency control and timing solutions to government and commercial partners. The system will integrate state-of-the-art diamond-based quantum sensing with robust system engineering for field deployment.

As a subcontractor to Leidos, Frequency Electronics will lead the design, prototyping, and testing phases of the NV Diamond magnetometer over the multi-year effort. This initiative aligns with broader national investments in quantum technologies aimed at enhancing situational awareness, navigation, and detection capabilities.
