Italian submarine Giovanni Bausan
1928 Pisani-class submarine
Giovanni Bausan was one of four Pisani-class submarines built for the Regia Marina (Royal Italian Navy) during the late 1920s. Due to her age, her usefulness was limited, and she saw no real service during the war. The submarine was decommissioned in 1942 and converted into an oil barge.
Design and description
Designed in parallel with the Mameli-class submarines, the Pisani class was larger accommodate more fuel and give them more range. They displaced 880 metric tons (866 long tons) surfaced and 1,057 metric tons (1,040 long tons) submerged. The submarines were 68.2 meters (223 ft 9 in) long, had a beam of 6.09 meters (20 ft) and a draft of 4.93 meters (16 ft 2 in). They had an operational diving depth of 90 meters (300 ft). Their crew numbered 48 officers and enlisted men.
For surface running, the boats were powered by two 1,500-brake-horsepower (1,119 kW) diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a 550-horsepower (410 kW) electric motor.

Why this record matters
“Italian submarine Giovanni Bausan” is worth following because a concise public description often conceals a longer documentary argument. Here, Italian, submarine and Giovanni provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Dec 15, 2025. The linked authority identifier is Q3766788. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1942.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
