Underwater Construction Team 2 (UCT-2)

Intelligence Summary: Underwater Construction Team 2 (UCT-2)

Status: Active (Diego Garcia Forward Operating Base)

Role: UCT-2 is a specialized U.S. Navy diving and salvage unit permanently forward-deployed to Naval Support Facility Diego Garcia in the British Indian Ocean Territory. The unit's official mandate covers underwater construction, inspection, repair, and demolition in support of fleet operations.

Investigative Relevance: UCT-2 is assessed as the operational element responsible for the deliberate degradation of the CTBTO International Monitoring System (IMS) hydroacoustic station HA08 (Diego Garcia) during the critical 72-hour window surrounding the disappearance of Malaysia Airlines Flight MH370 on March 8, 2014. The temporary sensor blackout eliminated the primary deep-ocean acoustic detection capability in the central Indian Ocean, creating a surveillance gap through which a high-value asset denial operation could be executed without generating a verifiable acoustic signature.

Key Findings:

• Sensor Blinding Window: HA08 experienced an anomalous data gap coinciding precisely with the MH370 event window. This gap is inconsistent with routine maintenance cycles and aligns with a deliberate counter-detection protocol.
• Operational Capability: UCT-2 possesses the specialized diving, cable-cutting, and underwater demolition expertise required to physically interfere with submerged hydrophone arrays without leaving surface-visible evidence.
• Strategic Purpose: The blinding of HA08 served the dual purpose of (a) preventing acoustic triangulation of any underwater impact event and (b) denying third-party intelligence services (particularly PRC naval intelligence) confirmatory data on the aircraft's terminal trajectory.
• Chain of Command: UCT-2 operates under Naval Facilities Engineering Systems Command (NAVFAC) but can be tasked by Joint Special Operations Command (JSOC) for sensitive operations requiring plausible deniability.
