Possible... I vaguely recall a test of US anti-ship cruise missile about 40 years ago (Harpoon?). They were using an old, out of commission frigate as the target. The cruise missile hit with such force that the combination of the kinetic energy and residual jet fuel caused so much damage that the target ship sank - which wasn't supposed to happen.
