- Population
- Federal Shipbuilding construction trades 1944-45; wartime and reserve-training crew (design complement 186 per DANFS)
- Limitations
- DANFS documents service history and specifications, not materials or asbestos content. It gives no keel-laying date, no target-sinking year, and spells the first commanding officer 'Chase' where NavSource reads 'Chace' - conflicts logged in gaps. Wayback capture cited because the live NHHC page returns 404.

Reads 'Newark' for the builder location where DANFS/NavSource read Kearny, and spells the first CO 'Chace' vs. DANFS 'Chase' - conflicts logged in gaps.

[4]DANFS specifications block (John C. Butler class; 24 kt; cpl. 186) + NavSource DE-510 specification block (2 'D' Express boilers, 2 geared turbine engines, 12,000 shp, 2 screws) + Atlas shipyard dataset, Federal Shipbuilding & Drydock record (federal-shipbuilding-kearny) [other_primary]

- Finding
- Era/design inference: a John C. Butler-class (WGT geared-turbine) destroyer escort built 1944-45 with two superheated 'D' express boilers and geared steam turbines (12,000 shp) would have carried era-standard asbestos applications - boiler and fireroom insulation, steam-line lagging, gaskets, packing, and fireproofing - during peak wartime asbestos use in Navy steam plants; builder Federal Shipbuilding & Drydock Co. (Kearny) is a documented yard in the Atlas shipyard dataset. The class profile records that the design group's boiler fit for the DE-508-510 block was Babcock & Wilcox (per a Navypedia block map - unverified against a primary source).

- Limitations
- Class/era and builder-yard inference only - NOT a hull-specific finding; no ship-specific asbestos record exists for DE-510. Does not quantify material, does not establish any individual's exposure, and the boiler-maker attribution (B&W) rests on a secondary block map.

[5]CourtListener API v4 litigation sweep (authenticated helper, fleet-paced): 'USS Heyliger' type=o and type=r; 'Heyliger' type=o (205 results) and type=r (603 results); 'Heyliger' + asbestos type=o (8 results) [court_record]

- Finding
- No qualifying asbestos litigation names this hull. Exact-name 'USS Heyliger' returned zero results in both the opinion and RECAP docket indexes. Bare-name 'Heyliger' returned 205 opinion results and 603 docket results - all person-name collisions on the surname (New York prisoner civil-rights and habeas cases, bankruptcies, Puerto Rico and U.S. Virgin Islands civil/criminal matters); 'Heyliger' + 'asbestos' returned 8 opinion hits including Virgin Islands asbestos mass-tort opinions that name persons surnamed Heyliger - no vessel reference. Hull-number query 'DE-510' could not be completed before filing (fleet pacing cap) and is logged pending in the search ledger.

- Negative result against the CourtListener index only - state-court filings, unindexed opinions, and settled/dismissed matters are not covered by this sweep; the 'DE-510' string query remains pending. Absence of located litigation does not establish absence of exposure claims ever made.
