- Limitations
- NavSource is a specialist naval-history compilation and is explicitly identified as a lead in this batch, but an accessible DANFS/NVR entry or Navy service card has not independently verified the construction and disposal dates. A second compilation gives 25 June 1999 for striking; retain only the month pending an official register record. This history proves no asbestos content or individual exposure.
