- ✗Significant sea duty
Real Opinions
+Positive
“I would recommend ST to anyone considering it. The training is solid and the community takes care of its own.”
“Sonar Technician is one of the most unique rates in the Navy. You operate and maintain sophisticated acoustic detection equipment — literally listening to the ocean. The focus and attention to detail required builds skills that employers in defense contracting, signal processing, and acoustics value highly.”
“STs develop an ear for underwater acoustics that takes years to master. Senior sonar techs are some of the most respected operators in the submarine and surface fleet. The TS/SCI clearance many STs receive adds significant civilian career value on top of the technical skills.”
–Critical & Mixed
“Like any rate, ST has its downsides. Long hours, time away from family, and Navy bureaucracy are real.”
“ST work is repetitive and monotonous — hours staring at a waterfall display waiting for something to appear. The excitement happens rarely. Most of your watch time is spent in a dark, quiet sonar room fighting to stay awake. On surface ships the sonar shack is isolated from the rest of the crew.”
“Civilian translation for sonar technicians is narrow. Unless you go into defense contracting or ocean acoustics research, explaining what you did to a civilian employer is difficult. Most former STs end up in general electronics or IT roles rather than anything sonar-specific.”
“The sea-shore rotation for surface STs is heavily sea-weighted. You're on a destroyer or cruiser for 3-4 years before seeing shore duty. The small community means limited shore billets and you may not get the location you want. Submarine STs have it even worse for work-life balance.”
Recruiter vs Reality
What the recruiter says vs. what it's actually like.
🫡 Recruiter says
“The ST 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 ST.
🫡 Recruiter says
“ST has great technical skills for civilian careers.”
💀 Reality
Source: sailor forumsST sonar experience is niche. Civilian sonar applications exist in oil/gas and marine science but jobs are limited. Many STs pivot to general electronics or acoustics careers.
🫡 Recruiter says
“Sonar Technicians on surface ships hunt submarines.”
💀 Reality
Source: veteran feedbackST work is similar to STG but focused on surface ship sonar systems. Long hours of watch standing monitoring sonar displays with occasional exciting contacts during exercises.
🫡 Recruiter says
“Sonar Technicians protect the fleet from submarine threats.”
💀 Reality
Anti-submarine warfare is critical, but peacetime ASW means long watches monitoring passive sonar with very few real contacts. You will become an expert at identifying biologics — whale songs, snapping shrimp — because those are 95% of what you hear.
🫡 Recruiter says
“ST is a great rate for people who love science and acoustics.”
💀 Reality
The underwater acoustics are genuinely fascinating. But the classroom theory gives way to operational reality: staring at waterfall displays, adjusting gain settings, and classifying contacts that are almost never hostile submarines. At sea, it becomes repetitive watchstanding with occasional intellectual challenges.
🫡 Recruiter says
“ST skills transfer directly to civilian sonar and acoustics careers.”
💀 Reality
Civilian sonar jobs exist in oil and gas, marine research, and underwater surveying — but the market is small and geographically concentrated. Many STs find their niche sonar skills do not directly match civilian demand. The stronger civilian play is pivoting to general electronics or signal processing roles.

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.
