The opinion states 'The on-site headquarters was on board the Navy's UEB-1 (Underwater Explosive Barge)' — UEB-1 carried the test officer-in-charge (Robert Krezel of the Underwater Explosions Research Division) and the test instrumentation umbilical connected the test model to the barge. Plaintiffs alleged injury while approaching/interfering with the test; judgment was entered for the United States (officer's conduct 'reasonable and appropriate'; discretionary-function and comparative-conduct grounds).

Per the opinions: on or about 8 August 1990 the tug CAPELLA allegedly collided with UEB-1 (owned and operated by the United States) at the test anchorage east of Key West, damaging the starboard stern ladder; on 10 August 1990 a weld securing the ladder allegedly gave way as plaintiff climbed it, causing the claimed injuries. Claims ran in admiralty against the United States (negligence/unseaworthiness) and against Lockwood; rulings addressed jurisdiction and the Suits in Admiralty Act — the Lockwood claim was dismissed for state-court pursuit; no merits finding on the injury claim appears in the published opinions.

- Finding
- Archival leads (not retrieved): (a) NHHC Collection 743 (Navy Laboratory Center Coordinating Group) records — including the UERD/DTMB detachment files for the Norfolk site — transferred to NARA College Park; the plausible series for UEB-1 operating records and any materials documentation. (b) NARA's asbestos-aboard-naval-vessels research guide maps RG 19 Bureau of Ships general/unclassified correspondence through 1961 — a window covering the barge's construction and early UERD service; BuShips/NNSY construction and outfit records for the barge sit inside that window, unsurveyed. (c) NARA RG 181 (naval districts and shore establishments) Norfolk Naval Shipyard records for hull/barge construction documentation.

- Limitations
- Record-location leads only — existence and content of any UEB-1/IX-509 file is unverified; NARA catalog API queries for the hull strings could not be completed in-session (API endpoint returned the catalog application shell, not results). Nothing in this row is an asbestos finding.
