I have never been navigated the ICW and I'm not familiar with the area near St. Andrew Sound but I have been following the development of various public-private launch facilities in the US. The Camden area was once considered as a site for the Apollo space program many years ago. There has been testing of solid fuel
rockets in that same area in the past, and a small rocket launch has already occurred there. The primary launch company is named ABL Space Systems, a group of former SpaceX engineers.
As far as I can tell, the FAA's environmental study didn't yield anything that they thought couldn't be offset by other means. The site is next to an existing landfill that some locals are concerned could be disturbed and cause runoff into the adjacent river. The USCG is in its assessment mode. Their request for comments for the establishment of a safety
zone for mariners has been posted:
It's a short document but it clearly states that the frequency of launches is expected to be 12 per year, during daylight hours, with a single
night launch possible in the same period. They also mention 12 static fire tests related to the scheduled launches. The safety zone proposed basically overlays the launch site eastbound, over the ICW and offshore
out to 13 nm, if I'm reading it correctly.
According to the document, "For launch activities, the safety zone is anticipated to be in effect for approximately four to six hours for medium-large launchers, but not longer than 12 hours. For small launches, the safety zone is anticipated to be in effect for two to three hours. A safety zone for rocket test activity is anticipated to be in effect for approximately 60 minutes or less
If I had to guess, the launches would be scheduled well in advance and would probably work
similar to the areas around Cape Canaveral. I would think that the activity would be posted on a publicly accessible website and appropriate radio
broadcasts would warn mariners in advance.
I've attached an edited image of NOAA chart 11504, and a Google
Maps screenshot of Pompey Island, GA, which is adjacent to the launch complex. I am really curious to see this industry open up. There's another launch site in southern Texas
that Camden County is hoping to match in terms of business and tourism.
