  The Nancy Grace Roman Space Telescope Coronagraph Instrument is a critical
technology demonstrator for NASA's Habitable Worlds Observatory. With a
predicted visible-light flux ratio detection limit of 1E-8 or better, it will
be capable of reaching new areas of parameter space for both gas giant
exoplanets and circumstellar disks. It is in the final stages of integration
and test at the Jet Propulsion Laboratory, with an anticipated delivery to
payload integration in the coming year. This paper will review the instrument
systems, observing modes, potential observing applications, and overall
progress toward instrument integration and test.
