Overview

An AN/SQQ-89A(V)15 Surface Ship USW Combat Systems Maintenance Technician starts and shuts down the system and performs organizational level maintenance on all functional segments. The technician interprets alerts and degraded or casualty indications, uses System Resource Manager functions to locate faults to the lowest replaceable unit, and performs prescribed preventive maintenance.

Core Skills

  • Built-in fault isolation to replaceable units
  • System alert and degraded-condition interpretation
  • Combat system startup and shutdown procedures

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

Using built-in diagnostics to isolate AN/SQQ-89A(V)15 faults to replaceable units and performing prescribed preventive maintenance transfer directly to electronic equipment troubleshooting and upkeep.

How to prepare: Complete a hands-on industrial electronics troubleshooting course that includes diagnosing faulty equipment with external test instruments.

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.
  • Inspect components of industrial equipment for accurate assembly and installation or for defects, such as loose connections or frayed wires.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS

Electrical and Electronic Engineering Technologists and Technicians

Interpreting system performance indications and localizing faults across combat system functional segments provide a foundation for electronics test and maintenance work.

How to prepare: Build a supervised bench-testing project that uses schematic drawings and external test equipment to diagnose an electronic assembly, documenting the measurements and fault-isolation steps.

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.
