Abstract: The Washington Double Star catalogs, maintained by the US Naval Observatory, are the world's principal database of astrometric double and multiple star information. Double stars showing significant relative motion are catalogued in the Sixth Catalog of Orbits of Visual Binary Stars (ORB6), a compilation of visual and astrometric orbits of more than 3500 binaries, and the Second Catalog of Rectilinear Elements (LIN2). The current status of each catalog and ongoing work to produce a new orbit catalog incorporating the ∼160,000 astrometric obits from Gaia DR3 are presented.% This new catalog will enable the identification of subsystems of visual binaries and increase our understanding of stellar hierarchies.
