    Limitations

    Confirms no qualifying ship-specific litigation was located via CourtListener as of 2026-09-24; does not rule out state-court or unindexed federal filings outside CourtListener coverage, and does not evaluate the merits of any case that might separately name this vessel. Litigation-stage discipline: no hit reached even the pleading-allegation stage for this hull, so no stage classification beyond 'no qualifying result' applies. 'Ebony' is a high-collision term (common given name, magazine, wood/material and product names) - classification was by identifier co-occurrence and full-text context check (two opinions pulled and read), not by name alone.

    Finding

    Archival leads (not retrieved - research-room or reproduction order required; no spend authorized): (a) NARA's digitized Navy deck-log catalog contains no Ebony entry as of 2026-09-24; WWII-era deck logs for YN-10/AN-15 (1941-1946), if held, are in RG-24 textual holdings at Archives II, College Park - these would document operations, availabilities, and any repair events; (b) RG-19 (Bureau of Ships) construction/contract records for General Engineering & Dry Dock hull 40 (contract NObs-344 per the Alameda NIRS record) - the yard's contract file and any Booklet of General Plans or specification sheets for the Aloe-class design; (c) RG-181 (shore establishments) - 12th Naval District records and forward-area net-defense files for Auckland, Noumea, and Espiritu Santo may hold the hull's 1942-45 assignment and maintenance files; (d) the MARAD disposition file for sale PD-X-1002 (1975-76) may name the dismantling location and any condition/inspection terms.

    Limitations

    Record-group mapping only - no box-level retrieval performed; existence of asbestos-specific documents for this hull is unknown until surveyed in person. The NObs-344 contract number comes from a secondary source (Wikipedia article on the yard) and is unverified against a primary contract record. Nothing in this row is an asbestos finding.
