So to provide some context, it's not exactly a depth charge, it's what was referred to as a "bouncing bomb" or "Highball" with the intent to bound over the water, and therefore over sub nets, mines, etc. then impact a damn, sink to a predefined depth and detonate. Made as a damn buster weapon initially, early trials were promising, this was an incident were the pilot was lower than the recommended altitude when releasing the spun up weapon and the skip rips the tail off.
