Hall PH

The Hall PH was an American flying boat of the 1930s. A twin engined biplane which developed from the Naval Aircraft Factory PN and could hence trace its lineage back to the Felixstowe flying boats of the First World War, the PH was purchased in small numbers by the United States Navy and the United States Coast Guard. It remained in service with the Coast Guard until 1944, being used for anti submarine and search and rescue duties.
