NSA Finally Unveils Redacted 1972 Journal Article After Decade-Long FOIA Battle

The National Security Agency (NSA) has finally released a heavily redacted version of a technical journal article from 1972 after a nine-year legal battle through the Freedom of Information Act (FOIA). The Black Vault, an independent research organization dedicated to uncovering government secrets, submitted its initial FOIA request on August 6, 2017, seeking access to the Fall 1972 edition of the NSA Technical Journal.

The document in question is titled "Maybe It’s Related to the Phase of the Moon..." and was authored by Herbert S. Guy, Jr. The article delves into the analysis of a callsign system, detailing the collaborative efforts between cryptanalysts, traffic analysts, and linguists. However, despite the long wait, only a small portion of the original text is readable in the released document.

The NSA's decision to heavily redact the document stems from its assertion that certain information within the article remains classified under Section 6 of Public Law 86-36 (50 U.S. Code § 3605). This federal statute allows for withholding information if disclosure would harm national security or other protected interests.

In its official response to The Black Vault, dated August 25, 2026, the NSA stated that it "reasonably foresees" that releasing additional details from the document could cause significant damage. Consequently, large sections of the article, including entire pages, remain undisclosed.

The release marks a pivotal moment in the ongoing debate over government transparency and accountability. While the partial disclosure provides some insight into the workings of the NSA during the early 1970s, it also underscores the agency's continued reluctance to fully reveal its historical operations and methodologies.

Critics argue that such extensive redactions hinder public understanding of the evolution of surveillance practices and their implications for civil liberties. The Black Vault has already indicated its intent to challenge the redactions through further legal action, aiming to secure a more complete release of the document.

The case highlights the complex interplay between national security concerns and the public's right to know about past government activities. As similar FOIA requests continue to be filed by various organizations and individuals, it remains to be seen how much additional information will be made available in the coming years.

Given the historical significance of the article and its potential relevance to ongoing debates on surveillance and privacy rights, this partial release is likely to spark further interest and scrutiny from both researchers and the general public. The Black Vault's appeal could set a precedent for future FOIA cases involving classified documents of similar vintage.

The full implications of the NSA’s response are yet to be fully understood, but it undoubtedly adds another layer to the ongoing conversation about transparency in government operations.
