Why 24-inch torpedoes fell out of favour

Why did 24-inch torpedoes fall out of favour?

Their logistics and handling burden outweighed the need for such a large weapon.

Logistics, handling, and the absence of a compelling requirement explain the disappearance of 24-inch torpedoes. Their larger diameter made storage, movement, loading, and shipboard support harder than for standard weapons. Once smaller torpedoes could meet the expected target set, the extra burden had little operational justification. Weapon effect was only one part of the procurement decision.
