SpaceX loses the center core of its Falcon Heavy rocket due to choppy seas
While I thought my question How vulnerable could space launch vehicles be to a “lone gunman”? was just my tangential thinking, this answer points out that
The Washington Post tells us that After 2016 rocket explosion, Elon Musk’s SpaceX looked seriously at sabotage.
The SpaceX employee who showed up at ULA’s facility had an odd request: Could he have access to the roof?
The reason, the employee explained, was that SpaceX had still images from a video that appeared to show a shadow, then a bright white spot, coming from the roof. ULA’s building was about a mile away from the launchpad and had a clear line of sight to it.
ULA was incredulous, and refused to let the SpaceX employee into the building. Instead, it called Air Force investigators, who inspected the roof and found nothing amiss.
Other people had theories as well: https://www.theringer.com/2016/10/4/16087232/ranking-potential-saboteurs-of-elon-musks-spacex-venture/
Along the same line of questioning, I was wondering what keeps North Korea or some other Wisenheimer from nudging a SpaceX drone ship from below, knocking the rocket off it's roomba-weld points into the sea, dragging it under water, then towing it away by submarine or other means in order to reverse-engineer its technology in order to build nuclear weapons that are lower cost and reusable.
Finding and pulling a dead rocket body up from the bottom is hard, A freshly dislodged object bobbing in the water would be much easier to grab.
Question: Does the US NAVY guard SpaceX drone ships and make sure bad actors don't abscond with critical technology on the high seas?
