John Holland's Submarine
USS Holland to today's subs
Shown above is the USS Holland, it was the first real, operational submarine. In the early 1900's the submarine was new technology, but by 1910 it was ready for war. At first submarines were not used as war ships but more as cargo ship destroyers. They could stay below the water and take out vital supply ships needed by the enemy. By the late 20th century submarines were powered by nuclear plants on board the ship and could launch sea to surface missile from underwater. Today submarines not only take down warships from under the water but they also threaten cities hundreds of miles inland with their nuclear missile capabilities.
