Cesare Laurenti (Terracina, 1865 â Rome, 1921) was an Italian naval engineer.
Laurenti was a naval engineering officer who designed submarines and founded a company to build them. He devoted himself to all branches of study in underwater navigation. In 1892 he became the director of technical experiments for the first Italian submarine, , which was driven by a battery-powered electric motor and designed by Giacinto Pullino. Laurenti transformed it by adding a gasoline engine, thus allowing a large surfaced cruising range while recharging the batteries underway. In 1909-10 he designed for the US Navy.
Laurenti is also credited with designing or assisting with the Provana class, 1905 Glauco class, Medusa class, Argonauta, F class, and the 1914 British S class (later Italian).
