Easily. Even without using Fast Passes, just the "default" relative velocity of 5mps for TL 7-8 missiles, a 20cm Missile (fired by a SM +5 Major Battery) can easily inflict 6dx25(2). An average of 525 damage, this will drop a SM +12 ship to 0 HP through DR 400. A SM +8 ship would almost certainly be destroyed instantly. If you add in higher relative velocities the devastation will be proportionally greater.

EDIT: Oh, just noticed that the errata not only corrected base projectile damage, but also default relative velocity. So a TL9 20cm missile would typically do on 6d10(2). That's still enough to disable a SM +12 ship, but only with DR 100. The max DR it could crack is about 700. But again, that's without making a Fast Pass.
