Overview

Active Sonar Level II technicians perform organizational level maintenance on the AN/SQS-53C Sonar System, AN/UQN-4/4A Sonar Sounding Set, and AN/WQC-2/2A Sonar Communications Set. They identify the sources of acoustic signatures and operate sonar processing, tactical towed array, variable depth sonar, and acoustic analysis subsystems.

Core Skills

  • Acoustic signature identification by source
  • Sonar and depth-sounding equipment maintenance
  • Underwater sonar communications equipment maintenance
  • Sonar signal processing subsystem operation

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 Installers and Repairers, Transportation Equipment

Organizational-level maintenance of shipboard sonar, depth-sounding, and sonar communications equipment transfers to transportation electronics repair.

How to prepare: Complete a hands-on marine electronics repair lab focused on circuit fault isolation and post-repair testing.

What the civilian work involves
  • Inspect and test electrical systems and equipment to locate and diagnose malfunctions, using visual inspections, testing devices, and computer software.
  • Reassemble and test equipment after repairs.
  • Locate and remove or repair circuit defects such as blown fuses or malfunctioning transistors.

Telecommunications Equipment Installers and Repairers, Except Line Installers

Maintenance of the AN/WQC-2/2A Sonar Communications Set provides an equipment-maintenance foundation for learning civilian telecommunications repair.

How to prepare: Take a telecommunications bench-repair course with practical exercises in circuit isolation and equipment acceptance testing.

What the civilian work involves
  • Test circuits and components of malfunctioning telecommunications equipment to isolate sources of malfunctions, using test meters, circuit diagrams, polarity probes, and other hand tools.
  • Test repaired, newly installed, or updated equipment to ensure that it functions properly and conforms to specifications, using test equipment and observation.
