British exposure to French submarines could create pressure to accelerate anti-submarine development. Older ideas for hydrostatic triggers could provide a starting point for a depth charge. Turning that principle into a usable weapon would still require substantial technical work. Fisher's preference for aggressive naval action could encourage faster development. Effective depth charges in 1904 remain a speculative wartime development.

Could wartime pressure accelerate depth-charge development?
A speculative response to French submarines considers whether existing ideas for water-pressure triggers could be turned into weapons sooner.
