I saw the press release and the video of the launch. Then I never heard anything about it after that. I hope it was one of the US Navy Submarine ??? That sounds really Creepy if it was launched from another Country's Sub.
Live on the opposite Coast and dead west of Cape Canaveral,,, I have seen several rocket launches,,,, that video in the recent press release off of California was most certainly an ICBM,,, and a big one.  You might check on You Tube for any follow up.
