Real Opinions

–Negative & Mixed
“Like any rate, STG has its downsides. Long hours, time away from family, and Navy bureaucracy are real.”
“Perhaps 5% of sailors who join into this job are satisfied. Sonar techs are usually very smart people, but they either have procrastination habits or they are very unruly.”

Horror Stories
Real stories people have shared about this rate. Swipe to browse.
“Command leadership would always blame you and throw you under the bus. That was the recurring theme in reviews from Sonar Technicians, and it captured something deeply corrosive about the work environment. Favoritism was apparent and openly ignored by those in charge. Only 40 percent of Sonar Technician reviewers said they would recommend the job to a friend. Poor leadership was driving high turnover, with more and more sailors actively telling others not to join. The technical work itself — operating and maintaining sonar systems, tracking contacts, standing watch in the sonar shack — could be engaging, but the toxic leadership dynamics poisoned the experience. When your chain of command played favorites and you knew that any mistake would be pinned on you regardless of the circumstances, it was hard to stay motivated or feel any loyalty to the organization.”

How do you choose the right Navy rate for you?
Choosing a Navy rate means weighing your ASVAB scores, lifestyle preferences, civilian career goals, and willingness to deploy or go to sea. Start by identifying which ratings you qualify for, then narrow the list by what matters most to you.
Getting Started
What is the ASVAB and what scores do you need?
The ASVAB is a multi-aptitude test that determines which Navy ratings you qualify for. Your sub-test scores combine into line scores, and each rating has minimum line-score requirements. Higher scores open more options.
