The bomb opens the Seung Un's side, melts its starboard power circuit, and forces a reactor dump while rescue ships race toward surviving crew.
The hidden explosive produces an orange flash amidships, then yellow sparks, then a major detonation that blooms open the destroyer's side. A likely power-conduit cascade turns the starboard main circuit into molten slag. Ten seconds later the crew ejects the fusion reactor core, which emerges brighter than the sun and diffuses into a vast golden aurora.
The core dump indicates the crew feared losing containment and also creates high-energy gas that disrupts rescue communications. Six ships divert around the hazard while Earth coordinates evacuation and medical support over public channels. Survivors are transmitting distress requests, though their number and condition remain unknown. No projectile or missile strike is visible, so analysis narrows toward accident or internal sabotage even as the false Holden Simulacrum claims responsibility.
The destroyer's side is torn open amidships, its starboard circuitry molten and its expelled fusion core expanding behind it as a brilliant gold cloud against black space.
The damaged Seung Un is now an active mass-casualty rescue scene and the physical evidence used to authenticate Holden's false confession.
