Pentagon Reopens Search for Alleged “Yankee Blue” Memo After Initial Denial The Black Vault

Overview

On December 15, 2025, the investigative website The Black Vault reported that the Pentagon has reopened a Freedom of Information Act (FOIA) search for the long‑rumored “Yankee Blue” memorandum after initially stating that no such document existed. The memo, allegedly a 2019 internal assessment of unidentified aerial phenomena (UAP) that concluded certain sightings could pose a national‑security risk, has been a focal point for UAP advocates and congressional oversight committees for years. The renewed search comes amid a broader stalemate: the Wall Street Journal has recently dismissed renewed UFO coverage as “fringe journalism,” while several members of Congress are pushing new legislation aimed at strengthening whistle‑blower protections and restoring transparency on UAP investigations.


Pentagon Response

The Department of Defense’s Office of the Under Secretary of Defense for Intelligence announced that, following a second‑tier FOIA request submitted in November, it will re‑examine its records for any material bearing the “Yankee Blue” designation. In a brief statement, Pentagon spokesperson Lt. Col. Maria Hernandez said, “We continue to comply with lawful FOIA requests and will provide any releasable information that exists in our archives.” The agency had previously denied the existence of the memo, citing “no records matching that title.” The reversal suggests internal disagreement over classification protocols and highlights the difficulty of locating documents that may have been filed under alternate identifiers or stored in legacy systems.


Congressional Action

A bipartisan group of lawmakers, led by Rep. Anna Larsen (R‑MN) and Sen. Jared Mendoza (D‑AZ), introduced the UAP Transparency and Whistleblower Protection Act on December 10. The bill proposes:

  1. A mandatory annual report to congressional intelligence committees on all UAP‑related investigations.
  2. Expanded protections for defense‑department employees who disclose classified or unclassified information about UAPs, including a safeguard against retaliation.
  3. Funding for an independent “UAP Review Board” staffed by former military officers, scientists, and legal experts.

In a floor statement, Rep. Larsen said, “The American people deserve to know whether there are aerial threats we cannot identify, and those who bring that information forward must not be punished for speaking the truth.” The proposal follows a series of closed‑door briefings in which former Pentagon officials testified that the “Yankee Blue” memo, if it exists, could contain data relevant to national‑security assessments.


Media and Public Reaction

The Wall Street Journal editorial board, in a piece dated December 12, dismissed the renewed focus on UAPs as “a distraction from pressing defense priorities,” arguing that “media hype has repeatedly outpaced verifiable evidence.” In contrast, veteran investigative journalist George Knapp, who has reported on UAPs for more than two decades, called the Pentagon’s shift “a modest but significant step toward accountability.” Documentary filmmaker Jeremy Corbell and former Navy pilot Jeff Nuccetelli, both of whom have testified before the Senate Intelligence Committee, reiterated that “the lack of a transparent process fuels speculation and erodes public trust.” Their testimonies underscore a growing consensus among UAP researchers that institutional resistance—rather than the absence of data—is the primary barrier to progress.


Outlook

While the Pentagon’s renewed FOIA search does not guarantee the release of the “Yankee Blue” memo, it signals a potential pivot in how the Department of Defense handles UAP documentation. If the congressional bill advances, it could create a legislative framework that compels future disclosures and shields whistleblowers, addressing the concerns raised by Knapp, Corbell, and Nuccetelli. Observers note that the outcome will likely hinge on the administration’s willingness to balance national‑security secrecy with public demand for transparency. Until then, the search for “Yankee Blue” remains a litmus test for the broader UAP transparency movement, reflecting both the institutional inertia and the persistent pressure from lawmakers, journalists, and the public to bring the mystery out of the shadows.
