The Swann stabiliser controlled the trim tanks on a leviathan to compensate for gunnery recoil.
History[]
The Swann stabiliser was one of several similar devices introduced in 1898.[1]
Uses[]
The stabilisers were fast-acting electromechanical controls that adjusted the vessel's trim tanks to compensate for the recoil of turreted weapons. This allowed for larger guns to be mounted on upper decks than previously feasible.[1]
Historical Notes[]
No specifics are given about the origin of the name "Swann" in canon. One likely candidate is Oliver Swann, an important figure in the early history of British naval aviation. This is only speculation, however.
