Sonar Technician (Submarine)
Operates sonar systems aboard submarines for anti-submarine warfare, mine detection, and undersea navigation. Serves aboard attack and ballistic missile submarines as a key member of the warfare team.
“You'll operate submarine sonar systems — the primary sensory equipment in an environment where acoustic detection is literally everything. Submarine sonar operators develop acoustic perception skills that take years to build and never fully degrade: contact classification from passive acoustic signatures is a cognitive skill that is rare and specifically valued. Submarine duty pays additional incentive pay, the community is genuinely elite, and earning your dolphins is a professional achievement that the submarine community takes seriously. Defense contractors supporting Navy undersea warfare programs — Raytheon, L3Harris — recruit STS veterans into acoustic analyst and sonar system technical positions. The clearance and the submarine qualification are both significant differentiators in the defense market.”
Submarine sonar is fundamentally different from surface sonar: your platform makes noise too, and the tactical equation is mutual — you are trying to hear them before they hear you, in an environment where physics determines the outcome more than doctrine. The BQQ-10 integrated submarine sonar suite processes input from the spherical array, the wide aperture array, and the towed array simultaneously, and your job is to manage all of it and identify what matters. The submarine is quiet — acoustic silencing is a design priority — and you become sensitized to every noise source aboard that could compromise your detection capability, which means you will spend a non-trivial portion of your career politely but firmly explaining to other rates why they cannot run that piece of equipment right now. Submarine life is 70 days submerged with a crew of 135, no sunlight, no phone calls, and the specific social physics of a small group of people who cannot get away from each other. The ocean acoustics expertise that submarine STS builds is among the most specialized technical knowledge in the Navy. Defense contractors maintaining submarine sonar systems hire directly from the STS community. The acoustic research community values your operational background. It is a rare and specific skill set, earned in a rare and specific environment, and both the scarcity and the environment are part of why people who do this job cannot fully explain it to people who did not.
MOS Intel
- 1Get your Dolphins as fast as possible — submarine qualification is the single most important milestone in your submarine career.
- 2STS on a fast-attack submarine is one of the most operationally intense enlisted jobs in the Navy. The sonar team drives the boat's tactical employment. Embrace the pressure.
- 3Submarine experience combined with acoustic/sonar knowledge translates to defense contracting roles with General Dynamics (Electric Boat), Raytheon, and L3Harris at $80-110K+.
Sonar Technician (Submarine) is where the submarine hunter/hunted dynamic is most real. The recruiter will talk about submarine life and sonar operations — both are accurately described as intense. You will spend months underwater, listening to the ocean, classifying every sound, and being the primary sensor operator for a nuclear submarine. The work is genuinely thrilling during operations and genuinely tedious during quiet transits. What they won't tell you: submarine life is not for everyone. No sunlight, no phone calls home, shared bunks (hot-racking on fast-attacks), and the psychological weight of being underwater for months. The submarine community demands your submarine qualification (Dolphins), and earning them requires learning every system on the boat. The civilian career path is specialized but well-compensated: undersea acoustics, submarine systems engineering, and defense contracting. Submarine veterans carry a quiet confidence that the rest of the Navy recognizes. If you can handle the lifestyle, STS is an extraordinary experience.
Execute the Job — By Rank
How you actually run this job at each rank — what you do, what you drill, which manuals you own, and what good looks like. Written for the soldier, sailor, airman, Marine, or Guardian currently in the seat. Each rank deeplinks into the full Playbook deep-dive: time-blocked schedules, unit-type variations, career decisions, and the read on the next rank.
You are a sonar student on a submarine you have not yet earned the right to stand watch on. The ocean is listening and you do not speak the language yet — that is the whole job for the next 18 months.
You arrive at STS "A" School at Naval Submarine School, Naval Submarine Base New London (Groton), Connecticut with a security clearance and a lot of ambition, and you spend the first phase of your career learning how sound travels underwater and why it matters more than almost any other physics you will ever apply in a Navy uniform. A-School covers sonar fundamentals: passive and active acoustic principles, signal processing concepts, the BQQ-10 or legacy BQQ-5 sphere array architecture, towed array operations, broadband and narrowband analysis, and basic target motion analysis (TMA). Before you check aboard a submarine you complete Basic Enlisted Submarine School (BESS), also at Groton — qualification in BESS is not optional and the sonar supervisor on the receiving boat already knows whether you graduated on time. Once aboard, Submarine Qualification (Sub Qual) PQS begins immediately and it is the most important thing you will do at this paygrade; the gold dolphins are not a second-tour goal. In between school, BESS, and PQS you stand sonar watches as a trainee, run preventive maintenance (PMS) on assigned sonar equipment, and learn the sonar shack from the junior-most watchstander's seat up.
- 01Identify the major components and functional architecture of the ship's primary sonar system (BQQ-10 series or installed suite) to the level required for Submarine Qualification PQS sign-off — sphere array, towed array, high-frequency array, and associated processing equipment.
- 02Execute PMS MRC cards on assigned sonar equipment — preparation, safety precautions, step-by-step execution, log entry — with no skipped steps and no items the sonar supervisor catches uncorrected.
- 03Perform basic broadband and narrowband display monitoring on an assigned watchstation under direct sonar supervisor supervision, correctly identifying contact presentations and reporting bearing, classification confidence, and hold/lost status in standard format.
- 04Complete BESS qualification and Submarine Qualification PQS on the LCPO's timeline — BESS before you check aboard, dolphins before or during the first deployment cycle; the sub community does not carry non-qual personnel indefinitely.
- 05Maintain security clearance currency: report reportable contacts, financial concerns, foreign national contacts, and any disqualifying information to the security manager proactively — not after the periodic review.
- 06Stand a sonar training watch under the sonar supervisor's direct supervision and demonstrate contact reporting procedures correctly — bearing call, classification call, hold/lost — in standard format, every time.
- —NSTM Chapter 565 — Sonar Systems (Navy Ships' Technical Manual); the technical reference for installed sonar equipment maintenance and operation aboard submarines.
- —NWP 3-21 series — Anti-Submarine Warfare; the doctrine framework behind every contact prosecution, barrier patrol, and torpedo evasion evolution you will train for.
- —OPNAVINST 3120.32 series (SORM) — Standard Organization and Regulations of the US Navy; watch organization, watchbill assignment, and the administrative structure of life on a submarine.
- —OPNAVINST 6110.1 — Navy Physical Readiness Program (PRT / BCA standard); submarine engineering and sonar spaces require crawling, carrying, and working in confined spaces — there is no waiver for physical readiness.
- —NAVPERS 18068 — Manual of Navy Enlisted Manpower and Personnel Classifications (NEC catalog); understand the STS-specific NECs and pipeline options before the first career counselor conversation.
- —Submarine Qualification PQS (Submarine Qualification Card, hull-specific) — the single most important qualification document at this paygrade; every signature on it is earned, not given.
- —BESS graduation prior to checking aboard the receiving submarine — a BESS failure delays check-in and flags the sailor to the receiving sonar department before day one.
- —Submarine Qualification (SS warfare device) earned within the first patrol or deployment cycle — the submarine community tracks non-qual sailors by name and the sonar supervisor knows the pace of every STSSN in the division.
- —All STSSN-level PQS line items signed off on the LCPO's timeline; advancement eligibility for STS3 tracking on schedule within the expected window.
- —PRT Good Low or higher; BCA in standard — sonar sphere-array compartments and towed-array spaces require full physical mobility; the duty section notices who cannot do the job in the dark at 0200.
- —Zero security incidents — unreported contacts, sloppy handling of classified material, or compartmented-information mishandling at any level produces an immediate command investigation and a PRP/security review that can end the sea assignment.
- —Reporting a contact bearing or classification without proper format — a garbled contact report during an actual prosecution means the OOD does not know what the sonar shack is tracking, and the sonar supervisor corrects it in front of the watch team.
- —Falling behind on Submarine Qualification PQS without telling the sonar supervisor early. The chief finds out regardless; the STSSN who flags it proactively gets mentoring, the one who hides it gets a formal counseling entry and loses the first-patrol qualification window.
- —Skipping a PMS step because the equipment "looks fine." Sonar equipment calibration and maintenance directly affect detection capability; a system that fails underway because the MRC was not completed correctly has your name in the log.
- —Treating security clearance requirements as administrative overhead. An unreported financial problem or foreign contact that surfaces through a periodic review instead of proactive disclosure is treated as an integrity failure, not a paperwork gap.
- —Discussing contact classification details, sensor capabilities, or patrol-area specifics outside of authorized spaces. Acoustic intelligence about submarine sonar performance is among the most closely held capabilities in the fleet — OPSEC starts in the sonar shack.
The good STSSN checks aboard, keeps his mouth shut, and finishes BESS and Sub Qual on schedule. His PQS board date is set before the sonar supervisor asks, his PMS cards are completed without supervision, and by the end of the first patrol the sonar chief is mentioning his name for the next training-watch upgrade. The dolphins go on before anyone has to push for them.
You are a petty officer with a crow and a pair of dolphins. The sonar shack trusts you to hold a watch. Now prove you can hold a contact.
You are a qualified sonar watchstander standing independent watches in the sonar shack of an attack submarine (SSN) or guided-missile submarine (SSGN). You monitor broadband and narrowband displays on the ship's sonar suite, track contact classification and bearing across watch sections, execute target motion analysis (TMA) procedures under the sonar supervisor's oversight, report contacts to the OOD in correct format, and run PMS on your assigned sonar equipment section. You train and mentor STSSNs through their earliest PQS line items and first training watches. The NWAE for STS2 is on the sonar supervisor's timeline and your eEVAL ranking against your peer STS3s starts to matter — the STS community on an SSN is small, advancement competition is visible inside the division, and the chief knows every score. If the boat has a towed-array system (TB-16, TB-29, TB-33 series), you are learning to stream and retrieve it and you are tracking narrowband tonal analysis as a skill the sonar supervisor expects you to be building.
- 01Stand an independent sonar watch — broadband monitoring, narrowband analysis, contact classification reporting, bearing rate assessment — clean enough that the sonar supervisor does not need to correct a call in front of the watch team.
- 02Execute towed-array stream and retrieval procedures (where installed) per the applicable technical manual, with safety precautions applied and the sonar supervisor's endorsement on the evolution log.
- 03Perform target motion analysis (TMA) using the installed fire control / sonar plot system to determine contact bearing rate, rough range, and course/speed estimate; brief the result to the sonar supervisor in a format he can pass to the fire-control party.
- 04Mentor an STSSN through Submarine Qualification PQS line items in the sonar spaces and sign the qual card with your name on the standard — meaning you checked the knowledge, not just the paperwork.
- 05Execute PMS on assigned sonar system components — sphere array, towed array, high-frequency array, processing equipment — to MRC completion standard; the sonar supervisor's spot-check finds nothing uncorrected.
- 06Maintain security clearance and classified material handling discipline on every watch — classified publications in hand only in authorized spaces, all printouts controlled, nothing written on unofficial material.
- —NSTM Chapter 565 — Sonar Systems; the technical maintenance and operation reference for every sonar equipment evolution aboard the boat.
- —NWP 3-21 series — Anti-Submarine Warfare doctrine; you operate within this framework on every underway and you can brief the basics to an STSSN without prompting.
- —Submarine Sonar Operating Procedures (hull-specific, controlled) — the on-board procedural reference for watch standing, contact prosecution, and emergency sonar evolution procedures.
- —NAVPERS 18068 — NEC catalog; understand the STS NECs (particularly the advanced analysis and towed-array NECs) and follow-on conversion options before career counselor conversations at the one-year mark.
- —NWAE Bibliography for Advancement (BIB) for STS2 cycle — current; pull from MyNavyHR / NETC, build a study plan with milestones, not a stack of PDFs.
- —OPNAVINST 6110.1 — Navy PRT / BCA; the PRT cycle continues during shore rotation and the sonar division chief is watching the trend.
- —Independent sonar watch qualification held and standing current — an STS3 who is not standing independent watches in a division with open watchbill slots is visible for the wrong reason.
- —STS2 NWAE preparation documented on the LCPO's timeline; EAW clean; in a small rating on a single submarine the advancement score is known across the division.
- —Towed-array watchstander qualification (where applicable) earned or actively in-progress; the STS3 who defers the qualification is deferring the watchbill contribution the sonar supervisor is counting on.
- —PRT Good Medium or better; BCA in standard; SS warfare device pinned and current.
- —Zero security violations — mishandled classified publications, unauthorized electronic devices in sonar spaces, or unreported clearance-relevant events. One event triggers a command investigation at the CO level.
- —Calling a contact bearing with low confidence and not flagging the uncertainty. An uncertain contact reported as a solid classification misleads the fire-control party; the correct call is "possible contact, confidence low" — the sonar supervisor works with honest data, not optimistic data.
- —Running a towed-array stream or retrieval evolution from memory instead of the applicable technical manual. Towed arrays represent significant capability and significant cost; a procedural error that damages the array is a maintenance event that the entire chain traces back to the watchstander.
- —Logging a PMS step as complete when the verification was not done. The sonar system certification traces through your maintenance log, and the sonar chief reads it.
- —Discussing acoustic detection capabilities, tonal libraries, or specific contact encounters outside authorized spaces. This category of information is among the most sensitive the submarine carries — it does not leave the sonar shack in conversation.
- —Falling behind on STS2 NWAE preparation and telling the chief two weeks before the exam. The plan that was not briefed 90 days out is the plan the chief finds out about at 14 days — and the outcome is already set.
The good STS3 is the petty officer the sonar supervisor trusts to hold a contact across a full watch section without prompting. His towed-array qualification is on schedule, his PMS log is current, the STSSN he is mentoring has signed qual lines, and his STS2 study plan is on a schedule the chief reviewed before the exam cycle opened. The sonar chief already knows his name in the right context.
You are the working senior sonar watchstander. The junior STSs learn contact prosecution watching you run the shack, the chief is starting to mention your name for Senior Sonar Supervisor, and you own a piece of this division's acoustic picture that the OOD actually uses.
You are a qualified sonar watchstander running the sonar section during your watch as the senior contact tracker and, on some platforms, as the junior sonar supervisor. You hold contacts from initial detection through prosecution — broadband classification, narrowband tonal analysis, TMA plot development, bearing-rate track maintenance — and brief the sonar picture to the OOD and the fire-control party in format. You run PMS on your assigned sonar system sections, sign off STS3 and STSSN advanced PQS qualifications, write the section's PMS compliance input for the department head readiness brief, and mentor junior watchstanders on towed-array and sphere-array operations. The NWAE for STS1 is no longer abstract — the STS community on a fast-attack is a closed number, every advancement score is known in the division, and the sonar chief's eEVAL ranking input goes to the department head. If commissioning programs (LDO, Seaman-to-Admiral, ECP) are on your radar, the conversation with the career counselor and the CO starts now — the window narrows faster than it seems.
- 01Hold a contact through a full watch section from initial detection to OOD brief — broadband classification, tonal association, TMA bearing-rate plot, course/speed estimate — in a format the fire-control coordinator can work with immediately.
- 02Stand the sonar supervisor watchstation (where E-5 billet is available) during a contact prosecution, torpedo-evasion training event, or ASW exercise; own the sonar picture brief to the OOD without the senior sonar supervisor correcting the format.
- 03Execute towed-array operations — stream, manage depth/geometry for array performance, retrieve — per the installed technical procedures; understand the performance tradeoffs of towed array versus sphere array in shallow vs. deep water.
- 04Sign off STS3 and STSSN advanced PQS qualifications in the sonar spaces; your signature says the watchstander executed the skill to standard, not that they described it correctly on paper.
- 05Write the section's PMS compliance input for the department head readiness brief — completion percentages, deferred items, open discrepancies — clean enough the sonar supervisor presents it without alteration.
- 06Teach narrowband analysis — tonal identification, frequency tracking, library correlation — to junior watchstanders at the level where they can hold a contact under supervision without asking what they are looking at.
- —NSTM Chapter 565 — Sonar Systems; you own the technical reference for your assigned sonar equipment sections and brief the applicable chapter to STS3s before they sign the MRC.
- —NWP 3-21 series — ASW doctrine; you operate within this framework as a watch lead and brief the doctrine basis for contact prosecution decisions when the sonar supervisor asks.
- —On-board Sonar Acoustic Doctrine and classification procedures (hull-specific, controlled) — the section-lead watchstander knows which procedure applies before the sonar supervisor asks the question.
- —MILPERSMAN — start reading the articles governing commissioning programs (LDO, ECP, Seaman-to-Admiral) if the path is in consideration; the recommendation has to come from the CO, and the CO has to know your name for the right reasons.
- —NWAE Bibliography for Advancement (BIB) for STS1 cycle — current; build a study plan with milestones; the BIB is the exam.
- —OPNAVINST 6110.1 — PRT/BCA; the STS2 who lets physical readiness slip during shore rotation creates a readiness gap the sonar chief has to manage at the next PRT window.
- —NWAE for STS1 prep documented and on schedule; EAW clean; the sonar chief on a fast-attack knows every advancement score in the division before the cycle closes.
- —Sonar supervisor watchstation qualification earned or actively in-progress on platforms where E-5 billets permit it — the senior watchstander who is not qualified as supervisor is carrying the division's watchbill without filling the billet.
- —PRT Good High or better; BCA in standard; SS warfare device pinned and current.
- —PMS section completion rate at or above department average every patrol cycle; no deferred items that the department head did not know about in advance.
- —eEVAL trait average and ranking that supports EP/MP; the sonar supervisor knows the ranking before the EVAL board reads it.
- —Signing off a junior watchstander's PQS line without verifying the actual watchstation execution. The sonar supervisor's qualification card traces back to your signature — if the STS3 cannot hold a contact under supervision after you signed him off, your name is in the debrief.
- —Presenting a TMA solution to the fire-control party that the data does not support. An incorrect bearing-rate solution drives a targeting error in the fire-control problem; the OOD needs honest acoustic data, not a confident answer built on a weak track.
- —Running a towed-array casualty recovery procedure outside the published technical manual scope without a formal work authorization. Unauthorized repairs on sensor systems are a maintenance event, not a watchstander initiative.
- —Treating sonar classification briefings as fill-in-the-blank. The OOD takes torpedo defense actions and prosecutes contacts based on what you report — vague, equivocal, or guessed classifications are more dangerous than reporting "unresolved, tracking."
- —Bypassing the sonar supervisor to brief the fire-control coordinator or OOD directly on a developing contact. The chain runs through the supervisor; the OOD hears it either way, and how it got there is part of the story.
The good STS2 is the petty officer the sonar supervisor sends to run the sonar shack while he briefs the department head. His contact track briefs clean, his section's PMS numbers hold up to a spot-check, and his STS3 is on schedule for the next advanced PQS sign-off. His eEVAL bullets read contact-held, torpedo-evasion-trained, towed-array-qualified — not generic division-filler. The chief knows his STS1 NWAE plan and the department head already knows his name.
You are the LPO of the sonar division and the senior acoustic technical voice the OOD hears when it matters. The sonar chief is building the anchor package and every contact prosecution, every PMS cycle, and every junior watchstander's qualification carries your name.
You are the Lead Petty Officer (LPO) of the sonar division aboard an SSN or SSGN — the senior enlisted daily manager of watch scheduling, PMS compliance, watchstander qualification, training program execution, and personnel readiness for 6-15 STSs depending on hull and manning. You write four to six eEVALs per cycle that drive the advancement slate for the next NWAE. You own the sonar division's PMS and MRC accountability at the LPO level, manage classified material handling for the section, and act as the principal liaison between the sonar chief and the junior watchstanders on deckplate execution. You stand the Senior Sonar Supervisor watchstation during contact prosecutions, ASW exercises, and torpedo-evasion evolutions. The sonar division's acoustic picture during a high-value event traces through your watchstation. The Chief selection board is not a future abstraction; your LCPO is reviewing the package and every eEVAL and watchstander qualification outcome affects it.
- 01Run a sonar division PMS program through a deployment cycle — MRC compliance, deferred items, CSMP input for the department head readiness brief — with no discrepancies the department head did not already know from your reporting.
- 02Stand Senior Sonar Supervisor during contact prosecutions, torpedo-evasion events, and ASW exercises — own the sonar picture brief to the OOD and the fire-control coordinator without the sonar chief revising the format.
- 03Manage classified material handling for the sonar division — controlled publications in authorized spaces, accountability logs current, no unauthorized reproduction — in posture for a no-notice classified-material inspection.
- 04Defend the sonar division readiness brief — PMS completion, deferred maintenance, watchstander qualification currency, PRT/BCA posture — to the department head without having numbers rewritten.
- 05Mentor an STS2 through NWAE preparation and a commissioning-program packet if applicable, and counsel honestly when the path does not fit the sailor.
- 06Write an eEVAL block the department head can defend at a wardroom board — measurable acoustic and readiness accomplishments, named safety and PMS outcomes, the language the Chief selection board reads.
- —NSTM Chapter 565 — Sonar Systems; the LPO is the technical reference point the STS3s check before asking the chief.
- —NWP 3-21 series — ASW doctrine; the Senior Sonar Supervisor who knows the doctrine framework is the one the OOD calls first when an unusual contact presentation surfaces.
- —On-board Sonar Acoustic Doctrine and hull-specific classified technical manuals — the LPO knows which publication and which section applies before the department head asks.
- —MILPERSMAN — fluent in the articles governing advancement, administrative separation, NJP, and classified-material mishandling at LPO visibility.
- —OPNAVINST 6110.1 — PRT/BCA; you own the sonar division's physical readiness posture during shore rotation and you model it.
- —NAVPERS 18068 — NEC catalog; you mentor pipeline packets off current NEC source-rating messages, not stale folders.
- —Chief board packet under construction with the LCPO's eye on every line; eEVAL profile defensible at department head and CO level; SS warfare device pinned and current.
- —Sonar division PMS completion and deferred maintenance input defensible at department head level every patrol cycle — no surprises.
- —Senior Sonar Supervisor qualification held and current; the STS1 who is not qualified as Senior Sonar Supervisor on a hull where the billet is open carries the wrong flag into the Chief board.
- —Classified material accountability for the sonar division — zero unresolved discrepancies, access logs current, no gaps that surface through an outside inspection.
- —Zero eEVAL-attributable advancement failures: the STS1s and STS2s you rated and ranked should advance on cycle, and if they do not the department head will ask your LCPO why.
- —Briefing PMS or watchstander-qualification completion numbers you have not personally validated. The department head spot-checks; a discrepancy found during an operational readiness assessment carries your name.
- —Letting the division's classified material accounting slip because the patrol tasking is heavy. A classified-material discrepancy found by an outside inspection rather than LPO proactive disclosure is a career-level credibility event on a submarine.
- —Treating the Senior Sonar Supervisor qualification as something to work toward after LPO duties are organized. On an SSN the SSSO watchstation is the senior sonar technical qualification, and the Chief board reads what you hold.
- —Going around the LCPO to the department head or XO on a sonar readiness concern. The chiefs talk; the goat locker hears how the LPO managed his chain, and the Chief selection board feels it.
- —Writing an eEVAL that inflates an STS2's performance because they are a good sailor. The STS2 who gets an inflated eEVAL advances into a billet a better-performing petty officer needed; the department head and the Chief board recalibrate your judgment — permanently.
The good STS1 is the LPO the department head trusts to brief the sonar division's readiness without a rehearsal. His PMS records hold up on inspection, his classified material log is current without prompting, his STS2s are on track for advancement, and he holds the Senior Sonar Supervisor qualification on every hull he has served on. The LCPO already knows the Chief package without being asked.
You are the Chief. Making Chief in the STS community changes the job more than any other promotion — the CO and the XO look to you as the senior enlisted acoustic technical authority on a submarine where the sonar picture is one of the most operationally consequential products the crew generates.
As LCPO of the sonar division aboard an SSN or SSGN, you own enlisted execution of the acoustic analysis, watchstander qualification, PMS, and classified material programs for the sonar department. You write Chief-quality eEVALs that drive the STS1 and STSC advancement slate; you sit at department sync as the senior enlisted acoustic voice on every readiness, qualification, and personnel issue; you walk the sonar shack during a squadron inspection, a CSG ASW assessment, or a COMSUBRON visit and find the discrepancy before the inspector does. You build the next LPO. You run the division training program — tonal analysis, TMA refresher, torpedo-evasion procedure drills — at the level that shows up in the ASW exercise results. You mentor the next commissioning candidate. You enforce the acoustic doctrine standard the submarine fleet runs on, in the shack, personally, because the deckplate watches whether your watchstander qualifications match your command leadership.
- 01Run the LCPO bench for a sonar division — watchbill, PMS, qualification tracking, classified material accountability, advancement, PRP/security, discipline — with the weekly cadence the department head and CO can predict and depend on.
- 02Defend the sonar division's PMS completion, watchstander qualification currency, classified material posture, and acoustic readiness summary at department and command sync without the numbers being revised by the department head.
- 03Lead a sonar division through a COMSUBRON operational assessment, CSG ASW exercise, or squadron inspection as the senior enlisted acoustic technical voice on the deckplate — your post-event AAR is what the department head briefs up.
- 04Mentor three to five STS1s toward Chief-board-competitive packages; mentor at least one sailor per year into a commissioning program (LDO, ECP, Seaman-to-Admiral) or advanced NEC pipeline.
- 05Brief the CO, XO, and squadron / CSG staff on sonar division enlisted readiness, acoustic training status, and any emerging technical or personnel risk in language the commodore can defend to the next echelon.
- 06Manage division discipline at the Chief level: Article 15 input, retention recommendation, classified-material-incident administrative action, and separation recommendation with the documentation the CO and JAG require.
- —NSTM Chapter 565 — Sonar Systems; you are the senior enlisted technical authority for sonar equipment aboard and you are accountable to the department head for what certifications find.
- —NWP 3-21 series — ASW doctrine; the Chief who knows the doctrine behind the procedure is the one the department head and the CSG ASW coordinator defer to when an unusual prosecution scenario surfaces.
- —On-board hull-specific classified acoustic doctrine, tonal libraries, and sonar system publications — you set the standard for how the division engages these materials.
- —MILPERSMAN — fluent in the enlisted personnel articles governing PRP administrative action, NJP, separation, and NEC pipeline access at Chief visibility.
- —CPO 365 / CPO Initiation program guidance — the wardroom and the goat locker hold you to this from day one of the anchors.
- —OPNAVINST 6110.1 — PRT/BCA; you own the division's physical readiness posture and you are the standard, especially during shore rotation.
- —CPO Academy / Chief's Mess transition complete; functioning as a Chief in the mess and on the deckplate every day, not in title alone — the sonar division reads the difference.
- —Sonar division PMS completion, watchstander qualification currency, and classified material accountability defensible at department head, XO, and CO level every deployment cycle.
- —Division acoustic training program — tonal analysis, TMA, torpedo evasion, emergency sonar procedures — producing watchstanders whose performance tracks in ASW exercise results.
- —eEVAL profile and ranking that selects STS1s and STSCs from your division on schedule — measured by who actually advances.
- —Zero Chief-level integrity incidents — classified material mishandling, financial, fraternization, security clearance compliance failure. One of these at the Chief level ends the career and triggers review above the ship.
- —Treating the goat locker as a break from the sonar shack. The STS chief who is not physically present in the division during watchstander qualification events and PMS spot-checks is the one whose division develops habits he has to explain to the department head at the next assessment.
- —Delegating classified material accountability entirely to the STS1 LPO because "that is an LPO function." Classified material on a submarine is command accountability — the chief is the first line of enlisted ownership, and the department head's confidence in your tracking is what allows the relationship to function.
- —Allowing the sonar division to run torpedo-evasion procedures from habit rather than from the published on-board procedures. Procedures exist because the submarine community built them after incidents; the chief who allows informal drift owns the next incident.
- —Going public with disagreement with the department head or XO. The disagreement happens in the passageway, then in the office; you walk out aligned. The goat locker enforces it without the wardroom asking.
- —Letting the commissioning or advanced NEC mentoring conversation become a check-the-box exercise. The STSs you develop at STSC build the acoustic-intelligence and submarine sonar community for the next decade — counsel honestly about LDO ADSO, ECP timelines, and whether the path fits the actual person.
The good Chief Sonar Technician Submarine is the LCPO the CO names when the squadron commander asks which division chief has never surprised him. His sonar division passes every assessment without senior-enlisted-attributable findings; his STS1s pick up Chief; his commissioning and advanced pipeline candidates select above the community average. He is on the Senior Chief slate before the CMC has to suggest it.
You are the senior enlisted acoustic intelligence authority in the submarine force. COMSUBPAC, COMSUBRON, and the CSG ASW coordinator do not ask abstract questions at this paygrade — they ask yours.
As STSCS or STSCM you hold the senior enlisted STS seat at a submarine squadron (SUBRON), a CSG staff, a COMSUBPAC or COMSUBLANT staff cell, a Naval Undersea Warfare Center (NUWC) technical cadre billet, or at the STS community manager level through BUPERS/PERS-4 enlisted career management. You write fewer eEVALs but they are the ones that pick the next Chief and Senior Chief slate across the rate. You sit at command-team and staff-level sync as the senior enlisted acoustic voice on every STS-community decision: accession, training pipeline, retention, watchstander credentialing, and ASW proficiency outcomes across multiple platforms. You brief flag officers and NAVSEA / OPNAV-N97 (Undersea Warfare) leadership on STS community enlisted readiness and submarine acoustic proficiency. You build the next command CMC on a submarine. You start the post-Navy transition plan 24-36 months out — NUWC civil service acoustic analyst billets, naval defense contractor pathways, and DIA / NSA technical support roles where the STS community's acoustic expertise commands respect — because the community you leave behind determines whether the next STSCM was built in your image.
- 01Run a senior enlisted STS community climate — across a squadron, a CSG staff, or a major command cell — that produces qualified sonar supervisors, advancing petty officers, and commissioning accessions at rates above the community average.
- 02Brief the commodore, the type commander, or OPNAV-N97 leadership on STS community enlisted readiness, acoustic training proficiency, and ASW watchstander qualification posture in language the flag officer can defend at the next echelon.
- 03Sit on Chief and Senior Chief selection board panels, command CMC slates, and STS community career management processes with the discipline and confidentiality the convening authority requires.
- 04Translate COMSUBPAC / COMSUBLANT, OPNAV-N97, and NAVSEA Undersea Warfare policy into enlisted talent management decisions at the unit level and across the rate.
- 05Run a multi-boat ASW proficiency assessment, squadron sonar supervisor certification cycle, or CSG acoustic exercise program as the senior enlisted STS voice — your lessons-learned is what COMSUBRON reads in the post-event report.
- 06Execute a casualty notification with the dignity it requires. At this paygrade, you are the face the family sees.
- —NWP 3-21 series — ASW doctrine; you translate operational doctrine into enlisted talent management and training pipeline decisions at the community level.
- —NSTM Chapter 565 — Sonar Systems; you cite from it more often than you open it — but the NUWC rep and the NAVSEA technical authority know if you have not kept technical currency.
- —MILPERSMAN — fluent on enlisted personnel actions at the senior-enlisted threshold; you are in the room for NJP, high-visibility security incidents, separation, and PRP administrative action.
- —Senior Enlisted Academy (SEA, Naval War College Newport RI) reading list and CPO/COB Symposium materials — you consume doctrine and translate it down to the submarine level.
- —COMSUBPAC / COMSUBLANT, OPNAV-N97, and NAVSEA Undersea Warfare policy memos and NAVADMINs — pull each one current, not from a stale shared folder.
- —NAVPERS 18068 — NEC catalog and community manager guidance; the STSCM who knows the advanced NEC pipeline options is the one who places the right petty officers in the right billets before the detailer conversation starts.
- —Senior Enlisted Academy fellowship or equivalent senior-enlisted PME complete before competing for command CMC / COB slate on a submarine or major staff.
- —Community-level sonar proficiency and ASW watchstander qualification metrics defensible at flag and OPNAV level during your tenure — no senior-enlisted-attributable findings in any formal inspection or assessment cycle.
- —Commissioning and advanced NEC pipeline producing 1+ selectee per year from your sphere of influence — and the squadron staff can name them.
- —eEVAL profile that the senior rater can defend at command and staff level — your rated chiefs are advancing to Senior Chief and Master Chief on schedule.
- —Zero senior-enlisted-level integrity incidents — security clearance failure, classified material mishandling, financial, fraternization. One ends the career permanently and triggers review above the command.
- —Pretending to hold technical depth on current sonar system configurations when the last deckplate tour was years ago. Senior STSs lose acoustic technical authority by faking currency — the NUWC rep and the NAVSEA technical authority recognize it inside the same brief.
- —Letting a Chief-led division drift on acoustic watchstander qualification standards because "the department head has eyes on it." The senior enlisted STS authority owns enlisted execution posture; the assessment cycle finds it under your community.
- —Treating the commissioning and NEC mentoring as a signature on a form. The STSs you develop at STSCM build the submarine acoustic-intelligence and ASW capability the fleet depends on — counsel honestly about which path is right for which sailor.
- —Going public with disagreement with the type commander, NAVSEA, or flag leadership. Take it in the office, through the appropriate channel, and walk out aligned. The submarine senior enlisted community is small and the STSCM who breaks the rule is remembered in every future assignment conversation.
- —Confusing preparation for retirement with the job. Until you walk off that quarterdeck for the last time, the mission is the job — and the deckplate reads which one you are prioritizing.
The good Master Chief Sonar Technician Submarine is the senior enlisted acoustic authority COMSUBPAC and COMSUBLANT name without checking a roster. His community's sonar proficiency metrics and ASW watchstander qualification rates are in the top tier during his tenure; his commissioning and advanced-pipeline accession rate tracks above the community average; his rated chiefs advance to Senior Chief and Master Chief on schedule. When he retires, the acoustic standard he leaves is the one the next STSCM is measured against — and that is the only metric the community remembers.

Zero reviews for STS. Not because nobody has opinions — anyone who’s actually done Sonar Technician (Submarine) is carrying a full magazine of them — but because nobody’s put theirs on the record.
So here’s the deal: the first approved review of every MOS becomes its Founding Review. Permanently badged, permanently first. Every person who looks up STS from now on reads it before anything else — including the recruiter’s version.
We could fill this page with fake reviews tonight. Plenty of sites do. We never will — which means this space stays exactly this empty until someone who lived it goes first.
Anonymous by default — no name, no unit, fuzzy timestamps. Your chain of command never knows it was you.
