Enginemen 3rd class

• Origin of the Rate: The Engineman (EN) rating was established in the U.S. Navy in 1948, evolving from earlier motor machinist's mate specialties. • Role Aboard Ship: Enginemen 3rd Class (EN3) are responsible for operating, maintaining, and repairing internal combustion engines—primarily diesel engines—aboard Navy vessels. • WWII Legacy: During World War II, the forerunners of EN3 maintained the engines of landing craft and PT boats, playing a vital role in amphibious operations. • Critical in Damage Control: EN3s are often among the first responders during engineering casualties, using their technical knowledge to prevent or contain fires and flooding. • Deployed Worldwide: Enginemen 3rd Class serve on a wide variety of vessels, from destroyers and aircraft carriers to smaller patrol craft and even Navy tugs. • Engineering Watchstanders: EN3s routinely stand engineering watches, monitoring gauges and systems to keep ships running smoothly and safely at sea. • Coast Guard Service: The Engineman rating also exists in the U.S. Coast Guard, where EN3s often serve on cutters, supporting search and rescue, law enforcement, and environmental missions. • Nicknames and Camaraderie: Enginemen are sometimes called "snipes," a traditional naval nickname for engineering personnel who work below decks. • Adapting to Technology: Over decades, EN3s have shifted from working on steam engines to high-tech diesel and gas turbine systems—requiring constant retraining. • Notable Alumni: Several distinguished Navy veterans, including Medal of Honor recipient Francis C. Flaherty, held engineering ratings like Engineman 3rd Class during their service.
