On this day in history,...
in 1979, the legendary RV Vityaz was officially retired from service after three decades of groundbreaking oceanographic research. Originally built in 1939 in Germany as the Mars, the vessel initially served as a cargo ship and later a hospital ship during World War II. After the war, it was transferred to the Soviet Union as part of war reparations and renamed Vityaz in 1946.

In 1949, the ship underwent extensive renovations to become a fully equipped oceanographic research vessel, under the direction of the Academy of Sciences of the USSR. From then until 1979, the Vityaz participated in more than 65 expeditions, contributing significantly to the exploration of the world's oceans.
Key Contributions:
- Exploration of the Mariana Trench: during a 1957 expedition, the Vityaz conducted one of the first accurate measurements of the trench, recording a depth of approximately 11,034 meters.
- Global Oceanographic Research: the Vityaz contributed to the study of ocean currents, deep-sea biodiversity, and chemical composition, helping build global oceanographic knowledge during the Cold War era.
- Scientific Collaboration: the Vityaz hosted numerous international scientists and played a crucial role in fostering cooperation in marine research.
After its retirement, the Vityaz was preserved as a maritime museum exhibit. In 1994, it was permanently relocated to the Museum of the World Ocean in Kaliningrad, Russia, where it remains a testament to the golden era of Soviet oceanographic exploration.
