117P9H3V0 is an orthogonal c/3 spaceship discovered by David Bell in May 1992.^{[1]} It is based on a period3 spaceship with a loosely connected back component which could be removed to form a period9 spaceship, being the first spaceship of this period to be found. The back part creates a blinker, which is deleted later. In September 1997 Bell found a smaller period3 component to support the period9 trailing edge. In June 2001 Paul Tooke found a much smaller period9 spaceship, 55P9H3V0.
The front engine of the spaceship is closely related to the dart.
