Current service use not established

This code is listed in the directory. Inclusion alone does not confirm current service use.

A Navy Enlisted Classification: a skill designation sailors hold in addition to their rating.

Overview

An AN/SPQ-9B radar technician performs organizational level preventive and corrective maintenance on the AN/SPQ-9B ASMD radar. The technician analyzes casualties, isolates faults, tests and repairs equipment and interfaces, and operates consoles during tactical situations, testing, and evaluation.

Core Skills

Circuit diagram-based fault isolation
Radar subsystem and interface alignment
Console operation during tactical and test activities

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 radar maintenance, fault isolation, and subsystem repair transfer directly to diagnosing and repairing commercial and industrial electronics.

How to prepare: Complete a hands-on industrial electronics troubleshooting lab that uses service diagrams to diagnose a fault and verify the repair.

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

Testing and aligning radar equipment, subsystems, and interfaces using circuit diagrams supports electronics test and troubleshooting work.

How to prepare: Build a civilian electronics test work sample showing a schematic, test setup, measured results, and the reasoning used to isolate a fault.

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.
