engineering is designing and building a
craft that has the capability to function and maneuver
underwater. Underwater crafts range in size, purpose,
and complexity. Some can fit in the palm
of your hand while others are large enough to hold
numerous amounts of people and equipment. Small subs
can be built to explore underwater places that a
human would not be able to access. The smaller crafts
often carry cameras that let humans at
the surface explore our amazing underwater world.
Some small underwater crafts, like ours, our built just as a
hobby and only work in a pool. Larger ones are often for use
in Navy work. They can transport people, and supplies underwater.
