Tranche 08 Preview: Defense Science Board Reviews Raw Telemetry

By UFO Disclosure Files Editorial Desk Published Updated Editorial analysis

Executive Summary

As defense agencies finalize preparations for the upcoming PURSUE Tranche 08 drop scheduled for early November 2026, the Defense Science Board (DSB) and the All-domain Anomaly Resolution Office (AARO) Scientific Advisory Group have initiated an exhaustive technical audit of queued telemetry packages. Under direct pressure from congressional armed services committees, the upcoming release is slated to transition beyond textual PDF summaries, unsealing raw binary radar tracks, uncompressed electro-optical/infrared (EO/IR) sensor streams, and calibrated radiometric data from military test ranges.

What to know

The scientific audit aims to establish standardized data verification protocols, ensuring that raw telemetry files can be ingested directly by civilian academic institutions and independent aerospace researchers. Priority datasets under review include phased-array radar recordings from the 2023 Lake Huron engagement, multi-sensor tracks from naval operating areas, and ground-based optical tracking data from national laboratories.

The Shift to Raw Data: Why Binary Telemetry Matters

For decades, official government UAP reports relied on qualitative narratives and heavily redacted summaries, drawing criticism from the scientific community.

  • Binary Radar Files: Unsealing native radar cross-section (RCS) data and Doppler phase measurements to evaluate true kinematic performance.
  • Radiometric Sensor Streams: Providing calibrated thermal and infrared data without lossy video compression artifacts.
  • Open Scientific Ingestion: Formatting defense sensor logs into open-standard formats for independent computational modeling by civilian universities.

The Defense Science Board Mandate: Independent Technical Rigor

Composed of leading civilian scientists, aerospace engineers, and former defense research executives, the DSB serves as an independent technical auditor.

  • Sensor Artifact Elimination: Filtering out common sensor artifacts, lens flares, and digital processing glitches before publication.
  • Multi-Platform Correlation: Cross-referencing simultaneous detections across airborne, space-based, and ground radar networks to confirm physical targets.
  • Scientific Disposition Papers: Authoring peer-reviewed technical appendices explaining why specific cases remain unresolved under known physics.

Priority Telemetry Sets Queued for Tranche 08

Intelligence sources indicate that Tranche 08 will focus on high-fidelity records collected during recent combat air patrols and facility intrusions.

  • Lake Huron Shootdown Telemetry: Releasing the complete AN/APG-79 radar track and cockpit heads-up display (HUD) recordings from the February 2023 intercept.
  • Naval Operating Corridor Sensor Feeds: Unsealing synchronized radar and sonar logs from East Coast and West Coast carrier strike group training ranges.
  • National Laboratory Perimeter Tracks: Calibrated optical and RF spectrum recordings captured during perimeter breaches at nuclear weapons facilities.

Congressional Oversight and Statutory Open-Data Standards

The audit responds directly to provisions in the FY 2026 National Defense Authorization Act mandating that federal UAP repositories adhere to open-data standards.

  • Statutory Open-Data Requirements: Forcing defense agencies to publish data in machine-readable, non-proprietary digital formats.
  • Subpoena Enforcement Deadlines: Lawmakers have warned that continued withholding of raw sensor feeds will trigger formal committee subpoenas.
  • The November Rollout: Tranche 08 is scheduled to debut on War.gov/UFO in the first half of November 2026, setting a new benchmark for transparency.

What to take from it

  • The Defense Science Board and AARO scientific advisory panels are auditing raw telemetry packages for PURSUE Tranche 08.
  • Tranche 08 is slated to unseal raw binary radar tracks, uncompressed EO/IR video, and calibrated radiometric data in early November 2026.
  • The release aims to provide machine-readable datasets for independent academic and computational analysis.
  • Congressional mandates in the FY 2026 NDAA are driving the transition from redacted textual memos to raw instrumental telemetry.
