The French submarine Junon (Q186), a Minerve-class vessel, was constructed at the Chantiers et Ateliers Augustin Normand yard in Le Havre. Laid down on June 9, 1932, she was launched on September 15, 1935, and officially commissioned into service on September 20, 1937. As a Minerve-class submarine, Junon was part of France’s naval expansion during the interwar period and into World War II, designed for reconnaissance and patrol duties. During the early stages of World War II, Junon operated primarily from Oran and Casablanca under the command of Lieutenant de vaisseau Jaume from August 1939. In March 1940, she returned to France for refitting. Following the German invasion of France, Junon was evacuated from Brest on June 18, 1940, to Plymouth, escorted by the tug Nessus and her sister ship Minerve, which was towed by Zeelew, with support from patrol vessels Pessac and Sauternes, and joined by the destroyer HMS Broke off Ushant. On July 3, 1940, Junon was boarded by Royal Navy troops as part of Operation Catapult, and she was transferred to the Free French Naval Forces on July 27, 1940. She was not recommissioned until February 1941 under Capitaine de corvette Jean-Marie Querville, who later became Capitaine de frégate. By August 1941, Junon served as the flagship of the 1ère Division de sous-marins des FNFL, alongside Minerve and Rubis. Throughout 1941 and 1942, Junon conducted patrols in the Bay of Biscay, Norwegian waters, and the Sognefjord area. Notably, she participated in Operation Musketoon in September 1942, landing British and Norwegian commandos near Glomfjord. She also engaged in attacks on enemy vessels in Vestfjorden and conducted reconnaissance missions observing German naval activity in Brest. In 1943, command shifted to Lieutenant de vaisseau Étienne Schlumberger, and after a refit in 1944, she operated in the Mediterranean before being placed in reserve at Oran in August 1944. Post-war, Junon was refitted in Brest in 1945, serving as a sonar training and ASW exercises platform until her decommissioning on December 6, 1954. She was scrapped in 1960, marking the end of her service life. Junon’s operational history highlights her role in Allied efforts in the Atlantic, Arctic, and Mediterranean theaters during World War II.
