Opinion of the Court
ration of a part (here, asbestos) that the manufacturer knows is likely to make the integrated product dangerous for its intended uses. The manufacturers respond that they had no duty to warn because they did not themselves incorporate the asbestos into their equipment; rather, the Navy added the asbestos to the equipment after the equipment was already on board the ships.
We agree with the plaintiffs. In the maritime tort context, a product manufacturer has a duty to warn when (i) its product requires incorporation of a part, (ii) the manufacturer knows or has reason to know that the integrated product is likely to be dangerous for its intended uses, and (iii) the manufacturer has no reason to believe that the product’s users will realize that danger. The District Court did not apply that test when granting summary judgment to the defendant manufacturers. Although we do not agree with all of the reasoning of the U. S. Court of Appeals for the Third Circuit, we affirm its judgment requiring the District Court to reconsider its prior grants of summary judgment to the defendant manufacturers.

Kenneth McAfee served in the U. S. Navy for more than 20 years. As relevant here, McAfee worked on the U. S. S. Wanamassa from 1977 to 1980 and then on the U. S. S. Commodore from 1982 to 1986. John DeVries served in the U. S. Navy from 1957 to 1960. He worked on the U. S. S. Turner.
Those ships were outfitted with equipment such as pumps, blowers, and turbines. That equipment required asbestos insulation or asbestos parts in order to function as intended. When used as intended, that equipment can cause the release of asbestos fibers into the air. If inhaled or ingested, those fibers may cause various illnesses.
