His contributions to Italian naval power were marked by the naming of the second Regina Margherita-class battleship as Benedetto Brin, among other commemorations.

The two men collaborated on major projects: Saint-Bon conceived a type of ship, and Brin made the plans and directed its construction.

[1] On the advent of the Left to power in 1876, Brin was appointed Minister of the Navy by Agostino Depretis, a capacity in which he continued the policies of Saint-Bon, while enlarging and completing the project in such a way as to form the first organic scheme for the development of the Italian fleet.

[1] During his eleven years in the ministry (1876–1878 with Depretis, 1884–1891 with Depretis and Francesco Crispi, 1896–1898 with Antonio Starabba, Marchese di Rudinì), he succeeded in creating large private shipyards, engine works and metallurgical works for the production of armour, steel plates and guns.

[1] In 1892, he entered the Giovanni Giolitti cabinet as Minister of Foreign Affairs, accompanying, in that capacity, King Umberto I and Queen Margherita to Potsdam, but chose not to act against France on the occasion of the massacre of Italian workmen at Aigues-Mortes.
