Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Electrical and Electronics Repairers, Commercial and Industrial Equipment

Maintenance of submarine navigation electronics, alarms, instrumentation and control systems transfers directly to commercial and industrial electronic equipment repair.

How to prepare: Complete a hands-on industrial electronics diagnostic course focused on testing unfamiliar control equipment and documenting repairs.

What the civilian work involves
  • Test faulty equipment to diagnose malfunctions, using test equipment or software, and applying knowledge of the functional operation of electronic units and systems.
  • Maintain equipment logs that record performance problems, repairs, calibrations, or tests.
  • Set up and test industrial equipment to ensure that it functions properly.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS

Merchant Vessel Mate

Navigation planning, chart correction, ship-control duties and watchstanding alongside navigators provide a practical foundation for merchant-vessel deck officer work.

How to prepare: Request a National Maritime Center evaluation of your official sea-service transcript, vessel details and assigned duties toward a mate endorsement; a DD-214 is not acceptable sea-service evidence. Entry requires an MMC with the appropriate officer endorsement, including Coast Guard approval of sea time, training, professional competence, age, citizenship, medical fitness and drug screening; most jobs also require a TWIC.

What the civilian work involves
  • Consult maps, charts, weather reports, or navigation equipment to determine and direct ship movements.
  • Steer and operate vessels, using radios, depth finders, radars, lights, buoys, or lighthouses.

Getting Started

  • Associate Electronics Technician (CETa)

    Validate foundational electronics knowledge when moving into civilian equipment repair.

    For: Electrical and Electronics Repairers, Commercial and Industrial Equipment

Notes & Sources

  • For merchant-vessel work, the Coast Guard determines the endorsement scope supported by military sea service; normally 60 percent of total time onboard is credited as equivalent underway service.
  • Open-ocean merchant-vessel service requires USCG-verified STCW training.
