Hall PH was an American flying boat of the 1930s. It was a twin-engined biplane, developed from the Naval Aircraft Factory PN and could hence trace its lineage back to the Felixstowe flying boats of World War I. It remained in service with the Coast Guard until 1944, being used for anti-submarine and search and rescue duties.
