Which one is more technologically difficult to build, the latest stealth B-2 bomber or the latest version of Virgina class submarine?
Don't forget the sound deadening material used to cover the sub(it's as advanced as RAM on the stealth airplane) and the screw is designed to do more than minimize cavitation. The shape also has a lot to do with the acoustic profile of the sub (banded or not, number of blades, how clean it is...)venuesystem said:apple and oranges... with planes you are trying to create a low radar profile. With subs the question of stealth boils down to platform noise. The shape of the hull/sail, minimizing cavitation on the screw, and keeping machinery noise to a tolerable level (off platform radiated acoustics) determines a subs stealth capability.
