Background information

John Eaves'  for this ship referred to it as a Starfleet "Elite Observation Vessel." According to Rob Bonchune, "The sketch seems more detailed as it has a Starfleet registry NC-27 on the side and has red bussards towards the front/side in front of the blue warp glow," that were apparently not added to the CGI model. 

According to Eaves "a stack of horseshoes on my desk was the visual inspiration behind the design."
