MVShannon, formerly known asMVGO Navigator, is one ofSpaceX'sDragon capsule recovery vessels. Owned by SpaceX through Falcon Landing LLC (which also owns SpaceX'sfairing recovery vessels and Elon Musk's private jet), this vessel, along with her sister ship,MV Megan, is designed to retrieve Crew and Cargo Dragon capsules aftersplashdown.

When a Dragon capsule is preparing to return to Earth,Shannon orMegan are dispatched to wait near the predetermined landing zone. After splashdown,fast boats deploy from the vessel, approach the capsule to perform safety checks, check on the crew, and prepare it to be lifted aboard the recovery vessel, where the astronauts can exit the capsule. NASA requires SpaceX to allow the astronauts to exit within 60 minutes of splashdown.

To support its mission, the vessel is equipped with a specializedcrane on thestern to pull the capsule up from the water, a medical unit to treat astronauts, and ahelipad to allow astronauts and any time-sensitive cargo materials returned from space to be quickly returned to shore.

GO Navigator's services were procured bySpaceX as a quick transport vessel, as a back-up toGO Searcher in the event of any technical failures.^{[citation needed]}

In 2018 and 2019, the vessel and its crew were deployed for several hours of training to prepare for the recovery of theDragon 2 capsules and theirastronauts. The vessel executed the recovery operations during theCrew Dragon In-Flight Abort Test.^{[citation needed]}

Between April and May 2019,GO Navigator was temporarily re-assigned to fairing recovery operations for theArabSat-6A,Starlink 0.9,STP-2, andAmos-17 missions.^{[citation needed]}

The vessel played a key role in the recovery operation ofSpaceX's first crewed mission –Crew Dragon Demo-2.^[3][4][5][6] along withMegan.^[7] Both the vessels are identical and equipped with a medical treatment facility,helipad, lifting frame, etc.^[8]

GO stands for Guice Offshore, the owner and operator of these types of vessels.^[9]

In early 2022, the vessel was renamedShannon afterSpaceX Crew-1 astronautShannon Walker, along withGO Searcher being renamedMegan afterSpaceX Crew-2 astronautMegan McArthur. They are registered to Falcon Landing LLC, a SpaceX-linked company that also owns recovery shipsBob and Doug andElon's private jet.^{[citation needed]}

The Vessel is being moved to the West Coast of the United States in December 2024 to support the Crew Dragon splashdown in the Pacific Ocean, due to the capsule's trunk falling into a populated area. It will go through the port ofLong Beach in California, the same location that the droneship Of Course I Still Love You has been since 2021, which was moved to the California coast to support Vandenderg launches and landings.

For theCrew Dragon Demo-2 mission, theGO Navigator had a broken backup generator; however it still completed its mission and recovered theEndeavour capsule from the sea. The recovery was impeded by private boats which circled the capsule in the water.
