Gianfranco Gazzana-Priaroggia

Gianfranco Gazzana Priaroggia (30 August 1912 – 23 May 1943) was an officer in the Italian Royal Navy (Regia Marina), and the highest-scoring Italian submarine captain of World War II.

World War II During the war, Gazzana-Priaroggia served on several submarines, most famously on the Enrico Tazzoli (as second-in-command of the fellow submarine ace Carlo Fecia di Cossato); then he was appointed commander of the Archimede and finally of . He was responsible for sinking 120,243 GRT (Bruttoregistertonnen, or BRT). With a higher score than Britain's Malcolm David Wanklyn in , or America's Richard O'Kane in (both later sunk), Gazzana-Priaroggia and Leonardo da Vinci were the most successful non-German submariner and submarine in the conflict.

On 23 May 1943, Gazzana-Priaroggia, returning from his last successful patrol (for which he had earned a battlefield promotion to the rank of Capitano di corvetta), died alongside his crew when the Leonardo da Vinci was sunk, with all hands lost, by the destroyer and the frigate west of Cape Finisterre. He was posthumously awarded the Medaglia d'oro al valor militare and Knight's Cross of the Iron Cross.

Legacy Two submarines have been named after him. The USS Pickerel which was transferred from the US Navy in 1972 and a Sauro-class submarine.
