Not the Heavy launched a few days ago, but the previous Falcon 9, launched a week ago and soft-landed in the water.
The booster tested high retrothrust landing. Like a lot of SpaceX’s successful tests, they didn’t expect the booster to survive virtually intact, so they didn’t have a plan in place to recover the thing. Officially that made it a hazard to navigation; boosters like this have carbon over-wrapped high pressure helium tanks and other splodey bits. Unofficially, I wonder if the real reason was a desire to keep the booster from falling into nefarious hands… not so much the likes of United Launch Alliance, but more like Bond villains or the Chinese government (but I repeat myself).
Exactly how the Chinese or SPECTRE would go about snagging a floatign rocket booster is anyone guess. The rational approach would be to pre-position a modified cargo vessel equipped with cranes and such… hardly likely to go un-noticed. Less likely would be to modify a submarine to rise up underneath it, latch on, poke some holes in it, sink and be on its way. Less likely still would be a giant dirigible or seaplane.
These are of course all silly. But then, the CIA paying Howard Hughes to scoop a Soviet ballistic missile sub off the ocean floor was a silly notion as well.
But to the specific topic at hand, I wonder if the strike operation was carried out with laser guided bombs or with gunfire. I suspect the former… a B-1 or B-52 laying waste seems like the sort of excessive drama the situation calls for.
