by renowned players in the Genoese business world, such as Giovanni Ansaldo, Raffaele Rubattino, Giacomo Filippo Penco and Carlo Bombrini.

Over the next twenty years, he aimed at making Ansaldo fully independent both in the ironworks and weapon-making areas, thanks to strong vertical integration.

When the company issued shares in the summer of 1918 worth 400 million lire Ansaldo employed 80,000 workers, had dozens of factories and controlled companies such as A. Cerpelli & C., Banca industriale Italiana, Cantieri Officine Savoia, Dynamit Nobel, Gio.Fossati & C., Lloyd Italico, Nazionale di Navigazione, Pomilio, Società Idroelettrica Negri, and Transatlantica Italiana.

The main figure in this rebirth, the engineer Agostino Rocca, reconfigured the structure and organisation of the company during his tenure as chief executive officer from 1935 to the end of World War II.

In 1948, IRI entrusted the company to Finmeccanica, which operated several reorganisation measures during the 1950s and 1960s, such as the relinquishing of all shipbuilding activities to Italcantieri of Trieste in 1966.
