Real Opinions
+Positive
“You 100% get out of it what you put into it and your mindset is everything. I had a great experience and would do it again.”
“I would recommend STG to anyone considering it. The training is solid and the community takes care of its own.”
“Surface sonar technicians operate the AN/SQQ-89 suite on destroyers and cruisers — genuinely sophisticated equipment. The troubleshooting and tactical skills you develop are strong, and the TS clearance opens defense contractor doors after the Navy. STG is one of the more intellectually engaging surface rates.”
–Critical & Mixed
“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.”
“Like any rate, STG has its downsides. Long hours, time away from family, and Navy bureaucracy are real.”
“STG on a destroyer means you spend most of your watch time in a dark sonar room staring at a display waiting for contacts. When nothing is happening — which is most of the time — it is brutally boring. The surface sonar community is small, which limits shore duty options and you can end up at the same type of ship for multiple sea tours.”
“Civilian career translation for surface sonar techs is narrow unless you go into defense contracting. The acoustic and signal processing skills are niche, and most civilian employers don't know what sonar is. The sea-shore rotation is heavily weighted toward sea duty, especially for junior STGs on DDGs and CGs.”
Recruiter vs Reality
What the recruiter says vs. what it's actually like.
🫡 Recruiter says
“The STG rate offers great training and career advancement opportunities!”
💀 Reality
Source: MyNavyRates researchTraining and advancement are available but vary by command and manning. Ask specific questions about sea/shore rotation, typical duty stations, and advancement rates for STG.
🫡 Recruiter says
“STG is exciting anti-submarine warfare.”
💀 Reality
Source: sailor forumsASW training exercises are exciting, but daily life is repetitive watch standing. You will become very familiar with biologics (whale and shrimp sounds) that are not submarines.
🫡 Recruiter says
“Sonar Techs hunt submarines like in the movies.”
💀 Reality
Source: veteran feedbackSTG spends hours listening to ocean sounds on headphones and staring at waterfall displays. Actual submarine contacts are uncommon during peacetime. The work requires patience and attention to detail.
🫡 Recruiter says
“STGs operate the AN/SQQ-89 — the most advanced surface ship sonar suite.”
💀 Reality
The AN/SQQ-89(V)15 is genuinely capable. But operating it means hours of passive monitoring where the ocean sounds like white noise, punctuated by classification drills. Actual submarine tracking happens mostly during exercises with cooperative targets.
🫡 Recruiter says
“STG is a small, tight-knit community aboard surface combatants.”
💀 Reality
Most destroyers have only 4-8 STGs in the sonar shack, so you build close working relationships. But small also means there is nowhere to hide. If you are weak on qualifications or make classification errors, everyone knows immediately.
🫡 Recruiter says
“STG gets to deploy the NIXIE torpedo countermeasure system.”
💀 Reality
AN/SLQ-25 NIXIE is a towed torpedo decoy, and STGs maintain and deploy it. But deployment is almost always during exercises, not in response to an actual torpedo. Most of your NIXIE interaction is maintenance: inspecting the tow cable and testing the decoy electronics.

Watch Standing
3-section underway (8 on / 16 off)
In a 3-section rotation, the crew is divided into three teams. Each team stands an 8-hour watch shift, then has 16 hours off. In port, you stand 24-hour duty roughly every 3 days — one out of every three nights you stay aboard the ship. Underway (when attached to a ship command), the watch schedule runs continuously with shorter rest periods between shifts.
Watch qualifications vary by command and platform. Expect to qualify within 90 days of reporting.
