- NHHC identifies the third Casco as Barnegat-class AVP-12, laid down at Puget Sound Navy Yard on 30 May 1940, launched 15 November 1941, and commissioned 27 December 1941, with a listed complement of 215. She served as an Aleutian and Pacific seaplane tender, was torpedoed at Nazan Bay on 30 August 1942, repaired at Puget Sound Navy Yard, decommissioned 10 April 1947, loaned to the Coast Guard in 1949, and sunk as a target on 15 May 1969.

- VA, Sources of asbestos exposure in the military; NHHC DANFS construction dates
- Finding type
- asbestos_application
- Finding
- VA states that asbestos-containing materials were used in Navy ships built before the mid-1970s, including engine and boiler rooms and other below-deck areas, and identifies gaskets, floor and pipe coverings, and related products as general military uses. Casco was built in 1940-1941, within that period.

- Population
- Navy shipyard workers and shipboard personnel generally
- Limitations
- VA describes Navy ships by era, not Casco or the Barnegat class. No named product is verified aboard Casco; diesel propulsion does not imply a boiler installation. This does not establish asbestos presence, location, quantity, exposure, or causation on this hull.

- Finding
- NARA's naval asbestos research guide directs researchers to RG 19 ship engineering drawings, including S39 insulation and lagging and S48 piping drawings, and to auxiliary-vessel General Information Books. It states that deck logs and muster rolls do not directly document asbestos in ship components.
