- DANFS entry for this hull, in full: 'LST-1050 was laid down on 23 December 1944 at Pittsburgh, Pa., by the Dravo Corp.; launched on 3 March 1945; sponsored by Mrs. Oscar Enigson, Jr.; and commissioned on 3 April 1945. Following World War II, LST-1050 performed occupation duty in the Far East and saw service in China until late January 1947. She was decommissioned and transferred to the Republic of China under the terms of lend-lease on 27 January 1947 where she served as Chung Lien (LST-209). The ship was struck from the Navy list on 12 March 1948.'

The accompanying LST design table gives the LST980-1059 group (which contains this hull): 328'0" oa / 316'0" wl x 50'0" beam, 2,366 t beaching displacement / 3,960 t trial / 4,080 t at limiting draft, 11.6 kt trial; propulsion 2 x 'G. M. Diesel, 12-567A', 1,700 shp, 2 propellers, Falk single reduction gears, 3 diesel-driven 100 kW 230V DC ship's-service generators, 4,320 bbl diesel fuel; total accommodations 13 officers / 106 enlisted; armament 2 twin + 4 single 40-mm AA mounts. No boiler columns are populated for the diesel LST groups - boilers appear only against turbine-powered LST-1153/1154/1155.

[4]Era inference anchored to: BuShips Ships' Data 1945 v2 LST design table (2 x GM 12-567A diesels, no boilers, for the LST980-1059 group) + era amphibious-ship construction practice (as consolidated in the fleet lst-1-class class profile) [other_primary]

- Finding type
- asbestos_application
- Finding
- A diesel-powered tank landing ship built December 1944 - April 1945 sits inside the Navy's documented asbestos-use era. The LST program was the Navy's largest WWII ship class - the BuShips roster enumerates hull numbers 1-1155 across the program's builder yards (the fleet lst-1-class class profile counts 1,052 built per its enumeration / 1,051 per canonical literature - discrepancy unresolved) including inland 'cornfield' yards. The official design table shows this hull's group (LST980-1059) carried twin GM 12-567A diesels and no boilers - the steam/boiler lagging pathway does not apply. Era-standard asbestos applications for a diesel LST of this period: diesel exhaust lagging and exhaust-flange gaskets, engine-room thermal and acoustic insulation, valve and machinery packing, deck coverings and tile, bulkhead and accommodation insulation, winch/crane brake linings, and electrical insulation.

Names era-standard applications, not confirmed installed materials; no quantity; no manufacturer attribution. Her 1947 transfer to the ROC means any post-transfer material record would sit in ROC Navy files, which are not accessible.

- NIOSH surveyed this hull's builder yard - the Dravo Engineering Works Division shipyard on Neville Island, then building barges and towboats - in 1979 (walk-through for the shipbuilding painters' health-hazard investigation) and 1981 (full industrial-hygiene survey, ~1,200 production personnel). The 1981 survey documented paint/coating-process exposures: lead and nuisance dust above OSHA standards, and toluene/xylene/naphtha/mineral-spirits mixtures exceeding NIOSH additive-criteria in the inner hull area. NEITHER report addresses asbestos.

- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - spanning this hull's entire U.S. construction and service era (1944-47); the 1975 policy removed asbestos insulation only when damaged or required for repairs, modified 1979 to selective replacement in high-maintenance areas.

CourtListener (authenticated API v4, 2026-10-02): 'LST-1050' returned zero opinions and zero dockets, 'LST 1050' zero opinions, 'Chung Lien' one opinion (a 2010 California name collision - not this hull); a yard-level 'Dravo' asbestos sweep surfaced Christman v. Dravo Corp. (ev-09), which names the builder yard but not this hull. The only 'asbestos aboard' material surfaced anywhere is generic law-firm listicle content covering all WWII hulls without primary sourcing - excluded by source policy.

- Absence of a located public record does not prove absence of asbestos aboard - era construction practice makes era-material presence plausible, and her 43-plus years in ROC Navy service (1947-c.1993) are effectively undocumented in English-language public sources.

- CORRECTION: the Wikipedia article for this hull carries copy-paste defects imported from a sister-ship article - its body text reads 'LST-537 was assigned to the Asiatic-Pacific theater' (naming the wrong hull) and states 'She was decommissioned on 29 May 1946' (a 29 May 1946 decommission/transfer appears in the first ROC-transfer batch - the future ROCS Chung Hai was decommissioned and transferred at Tsingtao on that date, per ROC-side secondary sourcing). Authoritative sources for THIS hull - DANFS, NavSource, the NavalCoverMuseum designation history, and the BuShips roster - all agree she decommissioned and transferred 27 January 1947 and was struck 12 March 1948. The Wikipedia infobox itself carries the correct 27 January 1947 date.

- Finding type
- litigation_documented
- Finding
- Published appellate opinion documenting the builder's own discovery admissions about asbestos in Neville Island LST construction: Dravo answered interrogatories admitting that 'from 1941 to 1945 the major portion of the ships that it built (over 145 LST-type vessels) were for the Bureau of Ships of the United States Navy and asbestos was used as pipe insulating material in the construction of motor vessels at the Neville Island building docks.' Plaintiff's decedent Jacob F. Christman worked for Dravo at Neville Island 1942-1945 as a mechanic/welder on the East Yard outfitting dock - per the estate's interrogatory answers, 'in hold of ship where they were putting up insulation, the asbestos was from Johns-Manville ... worked on the water on the outfitting dock, and down in the hold of the ship without sufficient air exchange.' He was diagnosed with mesothelioma May 1978 and died 21 February 1979; the estate sued Dravo and Johns-Manville. The Superior Court affirmed summary judgment for Dravo: the Longshoremen's and Harbor Workers' Compensation Act Sec. 905(a) exclusive-remedy provision barred the state-court tort action because Dravo had secured compensation insurance under Sec. 932 - a disposition on remedy grounds, not on any finding about asbestos exposure.

- Limitations
- Yard-level, discovery-stage record, not a hull finding: the Dravo admission covers the Neville Island yard's LST-type construction program 1941-1945 ('over 145 LST-type vessels') - a set that includes this hull (built there Dec 1944-Apr 1945) - but does not name or individually identify LST-1050. The decedent's exposure description is the plaintiff's interrogatory answer; Dravo's admission is the defendant's discovery response - both quoted verbatim in the opinion, neither tried to a verdict. The affirmed summary judgment is a merits-level negative for this plaintiff on exclusive-remedy grounds and adjudicates nothing about exposure. No quantity, no fiber data, no ship-specific application.
