Manning Marius Kimmel (April 22, 1913 – on or around July 26, 1944) was a United States Navy submarine officer in World War II and the son of Admiral Husband E. Kimmel. He served as both junior and executive officer on several submarines, and finally assumed command of USS Robalo as a lieutenant commander. Kimmel was reportedly killed when Robalo was sunk off the island of Palawan. However, the exact circumstances surrounding his death remain unclear. Biography Manning Kimmel was born in Washington, D.C. on April 22, 1913. His father was Admiral Husband E. Kimmel, who eventually became the commander of the Pacific Fleet at the time of the attack by the Japanese at Pearl Harbor, Hawaii. His mother was Dorothy Kinkaid (1890–1975), sister of Admiral Thomas C. Kinkaid. The younger Kimmel followed his father's footsteps and entered the United States Naval Academy, graduating in June 1935. Ensign Kimmel's first assignment was aboard the battleship USS Mississippi. He subsequently went to Groton, Connecticut in 1938 for submarine training. Upon completion of his training, Kimmel was assigned as a junior officer aboard the submarine S-39 and served aboard her until the middle of 1941.

In May 1944, Admiral Ralph Waldo Christie, commander of submarine operations out of Perth-Fremantle, relieved Stephen Ambruster of command of the Gato-class submarine USS Robalo (SS-273) and selected Lieutenant Commander Kimmel to be her new skipper. Kimmel took Robalo to the South China Sea to operate against tanker traffic trying to supply the Japanese fleet at Tawi Tawi. During one attack against a target, Robalo was attacked by a Japanese plane. Bombs from the plane severely damaged the submarine's periscopes and conning tower, and wrecked her radar. When diving to escape the aircraft, the main induction flooded and the boat plunged towards the bottom until Kimmel stopped her descent at 350 feet. Despite the damage, Kimmel insisted the Robalo remain on patrol. Admiral Christie was concerned that Kimmel was being
