	Tourism is also an important economic activity in this region. Many tourists visit the D-Day invasion beaches, including Utah Beach in the Cotentin. At Sainte-Mère-Église a few miles away from the beach, there is a museum commemorating the action of the 82nd Airborne Division and 101st Airborne Division. The "Cité de la Mer" in Cherbourg is a museum of oceanic and underseas subjects. The main attraction is "Redoutable", the first French nuclear submarine, launched in 1967.
