117P9H3V0 is a c/3 orthogonal spaceship discovered by David Bell in May 1992.[1] It is based on a period-3 spaceship with a front engine related to dart and a loosely connected back component which could be removed to form a period-9 spaceship, being the first spaceship of this period to be found. The back part creates a blinker, which is deleted later. It provides three sparks in generation 1.
In September 1997 Bell found a smaller period-3 component to support the period-9 trailing edge. In June 2001 Paul Tooke found a much smaller period-9 spaceship, 55P9H3V0.
On December 25, 2020, Chris Rowett found a small tagalong for the spaceship using a combination of ikpx2 and apgsearch.[2]
