Overview

An MK-15 MODS 31-33 SeaRAM CIWS technician performs preventive and corrective maintenance on assigned equipment at the organizational or intermediate level. The technician analyzes casualties, isolates faults, tests and repairs the system and its interfaces, and operates control stations, computers, sensors, and loading equipment for target evaluation, tracking, engagement, and kill assessment.

Core Skills

  • Circuit diagram-based electronic fault isolation
  • Video tracker and digital resolver maintenance
  • System and interface testing and alignment
  • Guided missile handling and loading

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

SeaRAM preventive maintenance, fault isolation, and equipment repair transfer directly to diagnosing and restoring commercial and industrial electronics.

How to prepare: Complete a hands-on industrial electronics troubleshooting lab that includes diagnosing a fault, repairing it, and documenting the verification test.

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

Electrical and Electronic Engineering Technologists and Technicians

Testing and aligning SeaRAM equipment and interfaces, maintaining signal-processing components, and using circuit diagrams provide a strong foundation for electronics bench testing and repair.

How to prepare: Build a civilian bench-test work sample using a nonmilitary circuit, documenting the schematic, test setup, measured results, and fault diagnosis.

What the civilian work involves
  • Modify, maintain, or repair electronics equipment or systems to ensure proper functioning.
  • Set up and operate specialized or standard test equipment to diagnose, test, or analyze the performance of electronic components, assemblies, or systems.
  • Read blueprints, wiring diagrams, schematic drawings, or engineering instructions for assembling electronics units, applying knowledge of electronic theory and components.
