Submarines.

Under water vessels and craft.

Before Irishman Hollande invented the Submarine with finances from the Irish Republican brotherhood, a fore runner of the IRA. The diving bell was really the only viable sub and we can only guess how long ago it was invented. Early records suggest the Greeks were the first, but we now understand that ancient Greek technology was only an advancement on existing ideas.

Today the Submarine in its many forms from warship to robotic craft has become an invaluable tool into research of the worlds seas, oceans and lakes. Man has gone to the Moon, planets, Mars and yet we still know very little of what lies at the bottom of the seas of our own planet.

Robotic technology was used first on the discovery of the wreck of the Titanic, the submarine has gone from the two barrel concept of Loch Ree in County Tipperary to the former Soviet class Typhoon the largest nuclear ICBM capable submarine in the world.
