GO Navigator is the backup Crew Dragon recovery vessel and support ship for GO Searcher. The ship, alongside GO Searcher, recovers Crew Dragon during aborts or normal splashdown scenarios. GO Navigator joined the fleet in August 2018.
GO Navigator was slowly upgraded to match GO Searcher throughout 2018/19. In late 2018 a raised deck was installed to support medical and storage buildings. In early 2019 a lifting A-frame, communication equipment and the first storage building were added. During a 40-day dry dock in September 2019, a helipad was installed. This final addition completed the vessel's transformation into GO Searcher's double
In April/May 2019, GO Navigator was temporarily re-assigned for fairing recovery for the ArabSat-6A, Starlink 0.9, STP-2 and AMOS-17 missions. The ship was fitted with inflatables and sent downrange to haul fairing halves from the water. The ship was successful and delivered a fairing half back to Port Canaveral during each mission.
