On March 31, 2026, Representative Anna Paulina Luna transmitted a four-page signed letter to Secretary of Defense Pete Hegseth establishing a hard congressional demand: 46 specific named UAP video files delivered to Congress by April 14, 2026. The letter does not request cooperation. It names footage by operational callsign, identifies the platforms involved, and sets an explicit deadline after which Luna has stated she will escalate through available congressional mechanisms.
The demand represents the most operationally specific public disclosure request in the history of congressional UAP oversight. Previous demands from members of Congress have sought categories of material — program documentation, witness access, AARO reporting. Luna's letter names individual files.
What Is Being Demanded
The 46 files identified in the letter span multiple service branches, multiple platforms, and multiple encounter types. Among the named footage are engagements involving operational callsigns not previously disclosed in public record. Luna's letter includes material from fighter aircraft, fifth-generation platforms, and submarine-based sensor systems.
Specific named callsigns cited in the demand include Toxic 6, Hackney 6, and Hellhound 1X. The most operationally significant item on the list — cited by name — is footage from an F-16C that engaged and shot down an unidentified aerial object over Lake Huron using an AIM-9X Sidewinder missile on February 12, 2023. That incident was publicly confirmed at the time as a shoot-down. What has never been released is the sensor footage from the engagement.
The footage exists. The platforms recorded it. The chain of custody is known to the Department of Defense. This is not a request for material that may or may not exist — it is a demand for material that is confirmed to exist.— Congressional framing, Luna letter, March 31 2026
Fifth-generation aircraft footage in the demand refers to material from F-22 and F-35 sensor systems — platforms that carry classified sensor suites whose data would carry significant evidentiary weight if released. The inclusion of submarine USO footage adds a domain not previously prominent in congressional UAP oversight, indicating the scope of the request extends across the full multi-domain encounter record held by the DoD.
The Named Callsigns
Among the 46 items in the demand, the following operational callsigns appear in the congressional record attached to Luna's letter:
- TOXIC 6
- HACKNEY 6
- HELLHOUND 1X
- F-16C / LAKE HURON
- 5TH GEN PLATFORM ALPHA
- 5TH GEN PLATFORM BRAVO
- SUBMARINE USO SERIES
- AEGIS SENSOR PACKAGE
The full 46-item list has not been published in unclassified form. The callsigns above represent those cited directly in the public-facing portions of Luna's correspondence. The complete list is understood to be attached to the classified annex of the letter.

Deadline stated: April 14, 2026
Consequence stated: Escalation through available congressional mechanisms
Why April 14
The April 14 deadline is not arbitrary. Luna's letter establishes it as the point at which a response from the Department of Defense becomes legally necessary for congressional oversight purposes. The UAP Disclosure Act framework, carried forward through successive defense authorization bills, establishes congressional authority to compel production of UAP-related material. Luna's letter invokes that authority.
If Hegseth responds with the 46 files by April 14, the disclosure timeline advances significantly — the footage enters congressional record and the question of its public release becomes the next contested ground. If Hegseth does not respond, Luna has indicated she will escalate. Either outcome advances the disclosure process. There is no path to the status quo ante.
The political context matters. Luna was among the members most directly involved in the passage of the UAP Disclosure Act provisions. She is not a peripheral figure making a symbolic demand. Her letter arrives with the backing of a caucus that has grown in membership and has demonstrated a willingness to use available procedural mechanisms to compel compliance from executive agencies resistant to oversight.
The Lake Huron Shoot-Down
The February 12, 2023 shoot-down over Lake Huron by an F-16C using an AIM-9X remains one of the most consequential and least publicly examined UAP-adjacent events in the public record. The Pentagon confirmed the shoot-down in real time. The object was described as octagonal with strings hanging beneath it, flying at approximately 20,000 feet. It was tracked. It was engaged. It was destroyed.
What was destroyed has never been stated publicly with precision. The material recovered — if any — has not been publicly accounted for. The sensor footage from the engaging aircraft, from accompanying aircraft, and from any ground or maritime sensors in range during the engagement has not been released. Luna's letter demands that footage specifically, by callsign.
The inclusion of the Lake Huron footage in a demand alongside material from Fifth-generation platforms and submarine sensors is a signal about the seriousness of what Luna's team believes exists. These are not requests for background briefing materials. They are demands for primary sensor evidence from direct encounters.
