BFR Heavy Variants
 
2 Attachment(s)
I have been watching SpaceX Starship and BFR and BFR Heavy (XBFR) variants. I am an originalist in the sense that I accept the reality that the original name of BFR was Big F'n Rocket. With F'n in its original non contracted meaning and word.

The latest image includes the new stated fins on the booster, but adds 2 side pods and accounts for the fin placement needed to fit. The boosters now have 3 fixed vacuum exit bells and 3 15 degree steerable central sea level bells.

Hope this helps for the sport scale crowd whether doing just a Starship, a BFR (boosted Starship), or a XBFR which currently has no stated missions. If I were to predict the future, it would be used in hammerhead mode for an extra wide payload, about twice the diameter of a BFR booster, such as a habitat or space station which itself would be deployable/inflatable.

If it were me I would do a 3 cluster of BFR boosters with up to a 2.5x diameter payload section.
