Overview

An MK-15 MOD 40 CIWS and RAM Defense Capability 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, radar equipment, display panels, and loading equipment for target evaluation, tracking, engagement, and kill assessment.

Core Skills

  • Electronic fault isolation using circuit diagrams
  • Signal processor and video tracker maintenance
  • System alignment and interface testing
  • Radar sensor heat exchanger maintenance

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

Preventive and corrective maintenance, fault isolation, and repair of electronic equipment and associated interfaces transfer directly to industrial electronics troubleshooting.

How to prepare: Practice diagnosing faults on an industrial electronics training bench and recording the tests and repairs in a computerized maintenance management system.

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.
  • Set up and test industrial equipment to ensure that it functions properly.
  • Maintain equipment logs that record performance problems, repairs, calibrations, or tests.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS

Electrical and Electronic Engineering Technologists and Technicians

Testing and aligning signal processors, radar sensor subassemblies, and system interfaces using circuit diagrams supports electronics test and engineering-support work.

How to prepare: Complete a bench-testing project that uses a schematic to diagnose an electronic assembly and documents measured performance before and after repair.

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.
