O'Brien

The O'Brien is a real attack submarine that now serves as a museum ship in Valdivia, Chile, where visitors can walk through its actual interior spaces. You can see the control room, torpedo tubes, crew sleeping bunks, dining areas, and engine compartments that reveal how this vessel operated underwater.

The submarine was built in Scotland in the early 1970s and served in the Chilean Navy for about three decades. After being decommissioned, it was permanently placed in Valdivia as a museum ship to preserve the nation's maritime defense history.

The submarine is named after John Thomond O'Brien, a fighter in Chile's independence struggle, connecting the vessel to national pride and history. Visitors experience the close-knit life the crew shared in confined spaces, gaining insight into the bonds formed through shared duty.

The ship is easily located at a peaceful waterfront spot in Valdivia with signs in multiple languages to guide you. Wear comfortable shoes since the interior passageways and rooms are quite narrow and require careful movement through the vessel.

The vessel was specifically designed for swift movements and surveillance missions, with a sleek hull and powerful engine that made it highly maneuverable underwater. Many visitors notice the wear marks on the boat tell the story of its intense operational history while showing it has been carefully maintained.
