KA-33 and the Gateway fleet
So, Gateway Station does have a large fleet of auxillary craft: work shuttles with tool waldoes on arms, cargo and personnel shuttles for moving between ships that are too large to dock directly, or don't wish to dock for any number of reasons (security, environmental restrictions, personal preferences), and short-range, high speed craft for joyriding and sight-seeing around the Aeolus system.
But there's one multi-purpose cruiser that is kept in its own dedicated sector of Gateway, with an exclusive maintenance gantry and reserved launch and approach lane.
The GSS Watney is built around a massive launch bay that can carry all 5 Axiom-class huskybots, as well as repair the platforms when needed. It has sufficient life-support for up to 12 passengers and crew, as well as several squads of Beta, Gamma, and Delta platforms kept in standby for on-demand activation. When the Watney is launched, KA's processing core is physically moved from its home location and installed in a dedicated chamber on-board. Communications and connection with Gateway is maintained through the dedicated channels of Huskynet.
