While taking a class on hydrospace vehicles (ships, submarines, hydrofoils, and hovercraft) I discovered that submarines have an efficiency advantage over surface ships; they don't have drag induced by the generation of the wave system (wake) that surface ships have. It seems like the ideal way to transport goods over long distances. However, there is a problem, loading and unloading of materials off of the submarine change its buoyancy.
On the other hand, an aircraft carrier is a very large ship and I doubt that all of the planes being in the air versus on the ship can't make much of a difference in its gross weight.
- btown 7y agoI can imagine a dock that has the ability to load extra temporary mass on and off a cargo submersible, all loading done completely underwater, to offset material being taken off the submersible. If the efficiency increases were significant, this could become worthwhile. However it's likely hard to beat the efficiency of how many cargo containers you can stack on a normal cargo ship, particularly while fuel is cheap.
