Machinist Mate

• Origins in Steam Power: The Machinist’s Mate (MM) rating was established in the U.S. Navy in 1884, coinciding with the Navy’s transition from sail to steam-powered vessels. • Nickname "Snipes": Machinist’s Mates, along with other engineering ratings, are often called "snipes"—a term that originated from British naval slang for engineers who worked below decks. • Submarine and Surface Roles: MMs serve on both surface ships and submarines, operating and maintaining propulsion systems, auxiliary equipment, and nuclear reactors on nuclear-powered vessels. • Vital During World War II: During WWII, Machinist’s Mates were critical in keeping ships operational, often performing repairs under fire during battles such as the Battle of the Atlantic and Pacific island campaigns. • Nuclear Power Program: The Navy’s Nuclear Power Program, established in the 1950s, led to the creation of the Machinist’s Mate (Nuclear) specialty, making them among the most technically trained sailors in the fleet. • Emergency Repairs: MMs are known for their ingenuity—stories abound of them fashioning parts from scrap or making emergency repairs with whatever materials were available to keep ships in the fight. • Engineering Watches: MMs stand critical engineering watches, monitoring and adjusting everything from steam pressure to coolant flow, ensuring ship safety and propulsion at all times. • Women in Engineering: Women first entered the Machinist’s Mate rating in the 1970s, and today, female MMs serve on both surface ships and submarines. • Notable Alumni: Several former Machinist’s Mates have gone on to prominent careers, including politicians, astronauts, and inventors—showcasing the technical training provided in the role. • Traditional Rivalries: There is a long-standing friendly rivalry between Machinist’s Mates and Electrician's Mates, each claiming their systems are most vital to the ship’s operation!
