There is a new flame deflection system that sprays water from a water cooled metal plate under the pad. There wasn't any damage from a recent static fire test, but that was only half power compared to liftoff thrust. We'll see how it fares against a real launch soon.
The bidet is flat, so you can't see it from this angle. This is the current rocket stack. You can see the new hot staging ring at the top of the booster.
Oh you’re totally right I missed that. I thought the deluge system stuck up higher out of the ground but I guess that was before they finished the surrounding concrete.
