Almirante Maximiano

The Almirante Maximiano (H-41) is an icebreaker and oceanographic research vessel operated by the Brazilian Navy. It is primarily deployed in support of the Brazilian Antarctic Program (PROANTAR), conducting scientific research and providing logistical support in polar environments. The vessel features advanced laboratories, modern oceanographic sensors, and a flight deck for helicopter operations.

Originally constructed in 1974 by Todd Shipyards in the United States as a commercial supply vessel, the ship underwent several conversions before being acquired by the Brazilian Navy in 2008. Following an extensive refit and modernization process in Germany, it was officially commissioned into naval service in February 2009. Since its commissioning, the vessel has completed numerous annual Antarctic expeditions, playing a vital role in climate, marine biology, and geological research.
