Henri Deplante: Dassault Aviation's Key Figure in Aircraft Design

Henri Deplante, a significant figure in Dassault Aviation's history, dedicated over 30 years to the company's aircraft design, from 1949 to 1981. His association with the company began in 1930 when he met Marcel Dassault (then Marcel Bloch) and secured a position as an aircraft designer.

DePLante's early assignments included the development of the first metal aircraft. He was part of the team that built the triple-engine MB 60 for postal services in just seven months. Before World War II, he also worked on the MB 80 air ambulance and numerous prototypes.

After the war, DePLante served with the SAS shock paratrooper squadron and was personally involved in the D-Day landings. Following the war, he served as technical director at SNCASO, where he led the development of the first jet-powered fighter aircraft, including the Triton, Espadon, and Vautour, as well as the SO 30 Bretagne transport plane.

He rejoined Dassault in 1949 and became technical director at the age of 42. Together with engineer Jean Cabrière, DePLante spearheaded the development of key Dassault aircraft, including the Falcon, Mercure, and Mirage series. His meticulous work ethic and leadership skills helped the company achieve a prominent position in the aviation industry.

DePLante was honored for his career with, among other distinctions, Commander of the Legion of Honor and several military awards. He passed away on March 16, 1996.
