Italian submarine Rugg. Settimo 1931-

On 22 April 1930 was the London Naval Treaty or the Treaty for the Limitation and Reduction of naval Armament signed between the France, Italy, Japan, United Kingdom and the USA. This Treaty included the restricting of the standard displacement and the gun calibres of submarines. The result was that the big gun submarine concept like that of the French submarine Surcouf was doomed to disappear. There were lists made of the submarines of the above mentioned five countries less than 13 years old or still being built. Tonnage 797 tons of 2.240lbs, armament in 1931 with 1-10cm/3.9” gun.
