DIA Explored 'Ultimate Wireless' Communications Using Gravitational Waves, Declassified Document Reveals

A declassified Defense Intelligence Agency reference document details theoretical work on high-frequency gravitational wave (HFGW) communications, which could transmit signals directly through the Earth with low probability of interception. The document, released under FOIA, describes potential applications including secure submarine communications and interplanetary navigation.

Declassified DIA Document Details Gravitational Wave Communications

A Defense Intelligence Agency reference document, dated 6 April 2010 and marked UNCLASSIFIED, outlines a speculative but technically detailed vision for communications using high-frequency gravitational waves (HFGW). Released through a Freedom of Information Act request and made available by The Black Vault, the document—designated DIA-08--005—was prepared under the Acquisition Threat Support program, with the author's identity redacted under statutory exemptions. Its central thesis is that HFGW could enable secure, through-the-Earth communications, a capability with obvious military value.

Unlike conventional radio waves, gravitational waves are theorized to pass through matter with negligible attenuation, meaning a beam could penetrate the entire planet. The document claims such a link would be extremely narrow and thus have a very low probability of interception, making it attractive for strategic communications. S.

intelligence community has formally assessed the potential of exotic physics for future defense applications. The record compiles decades of peer-reviewed proposals—fourteen laboratory HFGW generators…
