General Info: Enginemen operate, service and repair internal combustion engines used to power some of the Navy's ships and most of the Navy's small craft. Most Enginemen work with diesel engines. Enginemen also operate and maintain electrohydraulic controllable pitch propeller systems and steering engines, refrigeration and air conditioning systems, air compressors, desalinization plants and small auxiliary boilers. Active duty obligation is six years. Applicants will enlist for four years and concurrently execute an agreement to extend their enlistment for 24 months. Enlistee enters as an E-1 (fireman recruit). Advancement to E-2 (fireman apprentice) will be made after successful completion of recruit training.

Advancement to paygrade E-4 (petty officer third class) will be made after successful completion of initial school training and after all advancement-in-rate requirements (including minimum time in rate) are completed. Advancement to E-3 and E-4 is contingent upon maintaining eligibility in the Advanced Technical Field.
