Aquatic drones can't have that capability. It's pretty hard to transmit and receive radio waves underwater, so these drones are autonomous. They're given a mission, they go do it, and then they return to a spot to be manually retrieved. Apparently, while a group of drones was being retrieved, china "accidentally" snagged one. Back to the capablities though, since these drones are autonomous, you probably wouldn't know one was taken until you do a count after retrieval. Once it's gone, you might know where it is by GPS, but not who has it. Even if you can say, "Hey, it's in China", you don't know what it's immediate environment is. All of those things make self destructing a pretty dangerous/irresponsible thing to do.
