Barão de Teffé (H-42)

Barão de Teffé (H-42) was an oceanographic research ship of the Brazilian Navy. She was the first Brazilian Navy ship to bear this name in honor of Admiral Antonio Luis von Hoonholtz. Built as a freighter named Thala Dan at the end of the 1950s in Denmark, she was launched in 1957 and discharged from military service on 23 July 2002.

In 1982 she was acquired by the Brazilian Navy to be adapted and take part in the Operation Antarctica (OPERANTAR 1) of the Brazilian Antarctic Program (PROANTAR), being one of the pioneers of Brazilian missions to Antarctica.

In 2007, Barão de Teffé was reported awaiting wrecking in Rio de Janeiro. After failed Australian attempts to purchase and turn her into a museum ship, she was scrapped in Rio de Janeiro in October 2007.
