Web3 apr. 2024 · The hull, fin, control surfaces and any appendages (e.g. fixed tube for towed array) contribute to the generation of hydrodynamic noise either directly, or by disturbing the wake field entering the propeller disc, which in turn causes the radiation of … Web9 nov. 2024 · Radiation plating will shield the internal systems from effects of the radiation. It is not necessary for a ship to have all types of shields, it really depends on where the ship is being put to use. Depending on the use case it might make sense to use more advanced hull plates, as these provide a general damage reduction. Fabian (Counterpoint) rob wittman vs herb
