The foreground ship is the "Mercy" Class System Rescue Vessel that will be detailed in the book.  The two cargo ships are the old "Type MP" Imperial Transports that were detailed in GDW's "Rebellion Sourcebook" for Megatraveller.   The spacestation is the 12km+ long Mora Imperial Highport.  The planet even has roughly 92% water, just like the stats according to "Behind the Claw".
