- Official register record; establishes identity, builder, delivery, designation date, custodian, and current status. Contains no asbestos, materials, or survey information. Physical-characteristics block withheld by NVR public-information policy. Does not itself equate the craft with the 'Systems Measurement Platform' name used by NAVSEA — that identification rests on NavSource and the Colton shipbuilding list.

- Finding
- NAVSEA/NUWC Division Newport official Seneca Lake Sonar Test Facility pages describe the Systems Measurement Platform (SMP): catamaran-type configuration 192 ft x 120 ft, drafting ~3 ft; two 75x35-ft pontoons joined by an overhead center span housing offices, workspaces, two 42x22-ft laboratories, storage, and a galley; two 75x50-ft test wells; 200-ton derrick crane built into the superstructure; permanently moored near the center of Seneca Lake ~2.6 km off the western shore in ~460 ft of water; powered from the shore substation by underwater cable (2.2 MW at ~13 kVac, aboard power 480/208/120 Vac, DC to 5 kVdc); two equipment-handling barges and transport boats serve the facility.

Systems Measurement Platform'), corroborated by the NVR custodian field placing IX-310 at this facility. No asbestos or materials content stated.

- Limitations
- Compiled secondary archive, not an official record — but the standard photographic/spec reference for unnamed service craft, and the source that prints the 'IX-310 = Systems Measuring Barge' identification. Its 'acquired by the US Navy in June 1971' conflicts with the NVR delivery date of June 1969 (likely conflating the April 1971 designation); NVR adopted. No asbestos information.

- Finding type
- regulatory
- Finding
- GAO HRD-80-2 (October 1979) documents Navy asbestos policy timing: product specifications for thermal insulation were changed in 1973 to specify asbestos-free materials; the Navy's policy to eliminate asbestos where suitable alternates existed issued October 1975; and because pre-purchased asbestos stock was already installed in ships under construction, 'some ships were delivered with asbestos insulation as late as May 1978.' A craft delivered in June 1969 predates all of these controls — era-consistent with asbestos-containing outfit materials, though as a non-powered barge the steam-plant thermal-insulation pathway the report addresses does not exist on this hull.

- Navy shipbuilding/repair workforce (program context)
- Limitations
- Program-level documentation of Navy asbestos policy timing — does not name this hull or any craft; fieldwork yards were Long Beach and Norfolk naval shipyards. Establishes only that 1969 construction predated asbestos-elimination controls; a derrick barge's outfit (offices, labs, galley superstructure, crane machinery) is not the shipboard thermal-insulation subject of the report. Does not establish asbestos aboard this hull.

- Finding
- CourtListener litigation sweep for this hull: searches run on exact designation strings ('IX-310', 'IX 310') across the opinion index and 'IX-310'/'Systems Measurement Platform'/'Seneca Lake sonar' across the docket index. Result: PENDING — fleet-wide CourtListener pacing blocked all authenticated requests during the session; sweep could not be completed. Residual risk of a qualifying hit is low: the craft is unnamed (case-name search has no vessel name to match) and uncrewed.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, environmental report, or DANFS entry names this craft in the public sources searched; the only web presence tying 'IX-310' to asbestos is its appearance on asbestos-marketing ship lists (e.g., freeasbestostesting.com), which are non-qualifying sources not carried as evidence (see search_ledger).

- Absence of a located public record does not prove absence of asbestos aboard — a 1969-built craft predates the Navy's asbestos-elimination controls and its superstructure outfit materials are undocumented. Does not establish presence or absence; does not establish or defeat any exposure claim or legal eligibility.

- Finding
- Archival lead (not retrieved — no spend authorized): NARA's guided topic 'Researching Asbestos aboard US Naval Vessel up through 1961' maps the RG 19 Bureau of Ships correspondence path, but its coverage ends in 1961 — before this 1969-built craft existed. Construction/outfit records for Wiley hull 730 (1969) would sit in post-BuShips NAVSEA and Naval Ship Engineering Center series and NUWC Division Newport/Detachment Seneca Lake records; NVR historical data (custodian, designation chain) confirms the administrative trail exists. None surveyed.
