Could friendly depth charges damage another warship, as suggested in a question about Taffy 3?
Short answerA destroyer's charges detonating beneath a battleship after a collision provide one possible mechanism; the answer does not identify a Taffy 3 case.
NotesThe response shifts from the named action to the danger created by a friendly collision. Exploding depth charges below the larger ship could cause damage. It gives a general example, leaving the proposed Taffy 3 incident unverified.
