Shannon, formerly called GO Navigator, is an offshore supply ship owned and operated by Guice Offshore, and currently deployed as one of the SpaceX Dragon/Dragon 2 recovery vessels[2] along with Megan.[3] Both the vessels are identical and equipped with a medical treatment facility, helipad, lifting frame, etc.[4]
The vessel played a key role in the recovery operation of SpaceX's first crewed mission - Crew Dragon Demo-2.[5][6][7]
History
GO Navigator's services were procured by SpaceX as a quick transport vessel, as a back-up to GO 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 the Dragon 2 capsules and their astronauts. The vessel executed the recovery operations during the Crew Dragon In-Flight Abort Test.[citation needed]
Between April and May 2019, GO Navigator was temporarily re-assigned to fairing recovery operations for the ArabSat-6A, Starlink 0.9, STP-2, and Amos-17 missions.[citation needed]
GO stands for Guice Offshore, the owner and operator of these type of vessels.[8]
In early 2022, the vessel was renamed Shannon after SpaceX Crew-1 astronaut Shannon Walker, along with GO Searcher being renamed Megan after SpaceX Crew-2 astronaut Megan McArthur. They are registered to Falcon Landing LLC, a SpaceX-linked company that also owns recovery ships Bob and Doug and Elon's private jet.[citation needed]

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