AB vs STG
Aviation Boatswain's Mate (USN) vs Sonar Technician (Surface) (USN)
The Navy told both of these they were "the backbone of the fleet." That skeleton apparently has a lot of backbones.
Drop a camera into the AB's day and you'd see: one wrong step and you're a statistic. Pan over to the STG and the footage looks like a different documentary entirely: the ocean acoustics knowledge, signal processing background, and technical depth of the training translate to civilian acoustics roles in marine research, underwater survey operations, and defense contracting. Two MOS codes that coexist in the same military the way a submarine and a golf cart both qualify as "vehicles."

Recruiter vs. Reality
The pitch versus what people who actually did the job report back.
“You'll work on the flight deck of an aircraft carrier — one of the most dangerous and adrenaline-fueled workplaces on earth. ABs launch and recover fighter jets, manage jet fuel operations, and direct aircraft weighing 60,000+ pounds in spaces tighter than a parking lot. It's the closest thing to a controlled disaster the Navy runs every day.”
The flight deck will try to kill you. Jet blast, spinning propellers, arresting cables under tension, and aircraft moving in every direction — all on a pitching deck in the middle of the ocean. The work is physically brutal, the hours are relentless during flight ops, and the safety stakes are absolute. One wrong step and you're a statistic. The ABs who thrive love the intensity and take genuine pride in the fact that nothing flies without them. The civilian airport and aviation fueling industry hires from this background, but nothing on the outside matches carrier flight ops.
“You'll hunt submarines from the Combat Information Center of a Navy surface ship. The sonar tradecraft takes years to develop and the acoustic analysis skill is genuinely rare — contact classification from a passive signature is something you can't learn in a classroom and can't un-learn after you've done it. Raytheon, L3Harris, and the major sonar contractors know what STG experience means and will pay for it. It's one of the most niche and specifically valued specialties in the surface Navy, and the defense contractor demand for experienced STGs is consistent.”
You sit in a space called the sonar shack, wear headphones connected to an AN/SQS-53 hull-mounted sonar or the AN/SQR-19 towed array, and listen to the ocean. The acoustic environment of the deep ocean is not silent — it is full of biologics (whales, shrimp, fish), merchant shipping noise, environmental clutter, and the occasional thing that doesn't quite belong that you have to classify, track, and report. The discrimination between a real contact and a false alarm is a trained skill that takes years to develop and a specific kind of patience that not everyone has. The SQQ-89 combat system integrates your sonar data with the ship's tactical picture — you are an essential piece of the ASW (anti-submarine warfare) team. STG billet ships are primarily destroyers and frigates; ASW is a surface warfare core competency, not an add-on. The ocean acoustics knowledge, signal processing background, and technical depth of the training translate to civilian acoustics roles in marine research, underwater survey operations, and defense contracting. NAVSEA contractors working on sonar systems specifically recruit experienced STGs. The environmental acoustics research community (NOAA, WHOI, Scripps) values the operational background in a way that formal academic programs do not produce. You know what the ocean sounds like when something is wrong. That is not a trivial thing to know.
The Real Life
Same dimensions, side by side. AB on the left, STG on the right.

Operating and maintaining surface ship sonar systems — AN/SQS-53C hull-mounted sonar, AN/SQR-19 towed array, and torpedo systems. STGs hunt submarines. On a ship: standing sonar watches, tracking subsurface contacts, operating torpedo tubes, and participating in anti-submarine warfare exercises. The work requires patience, good ears, and the ability to interpret acoustic data.

A School at Great Lakes (IL) is about 23 weeks. Covers acoustic theory, sonar equipment operation, submarine classification, torpedo systems, and anti-submarine warfare tactics. The training is technical and requires a good ear for sound differentiation.

Low. Sonar operations are console-based in CIC and sonar control. Standard Navy PT requirements.

Sonar Technician (Surface) is the submarine hunter of the surface fleet. The recruiter will talk about anti-submarine warfare and sonar operations — and the work is genuinely fascinating when you're tracking a real submarine. The Tom Clancy stuff is based on reality. What they won't tell you: most of your time is spent in training exercises and routine watches where the ocean is empty. The thrill-to-boredom ratio is heavily weighted toward boredom. Sea duty is standard surface Navy — long deployments on destroyers and frigates. The rate is small, which can make promotion unpredictable. Civilian career translation is specialized: underwater acoustics, defense contracting (sonar systems), and oceanography are the primary paths. STGs who develop deep acoustic knowledge and get into the defense contracting world can earn well, but it's a niche market. A unique rate for someone who loves the science of sound and the hunt for submarines.
