The intentional, usually remote-controlled complete demolishment of a space vehicle, rocket, or missile after launching, because of a defective performance or for reasons of safety: "The destructs of the two missiles were done because they were malfunctioning and so they presented a serious danger for many people."

To do away with something or to tear it apart: "The engineers had to destruct the rocket for safety reasons."

That which destroys or abolishes itself: "The military missile automatically self-destructs if it goes off the programmed course."

"He was a rock star who self-destructed on drugs."
