Torpedoman's Mate

You are the newest set of hands in one of the Navy's smallest and most recently resurrected ratings. The torpedo — one of the most dangerous weapons on the surface Navy — is now your responsibility to learn, and the TM1 who hands you the PQS binder is not going to wait for you to catch up.

Out of TM "A" School at the Center for Surface Combat Systems (CSCS) Unit Yorktown, Virginia, you check aboard a surface combatant — most likely a DDG — and the Torpedo Division LPO hands you a PQS binder, a cleaning rag, and a direct view of what a torpedo tube and a Mark 46 or Mark 54 torpedo look like up close. Your first months are learning the torpedo handling and stowage systems, conducting PMS (Planned Maintenance System) checks on tubes, launchers, and associated handling equipment under a senior TM, standing watch over the torpedo magazine, logging maintenance in the ship's 3-M system, and accounting for every piece of ordnance in the inventory at every custody turnover. The rating was re-established in 2019 via NAVADMIN 225/19, so the community is small and the senior leadership is still building its institutional norms — which means you will be shaped by a relatively tight group of TMs who take the craft seriously. PQS does not sign itself, the magazine does not count itself, and the torpedo handling system does not run clean without someone doing the work.

• 01Complete TM-rate PQS and your ship's weapons-department watch qualifications on the LCPO's timeline — every line item walked and signed, never blank-checked, because a missed torpedo magazine check is an explosives-safety gap, not a paperwork gap.
• 02Conduct a torpedo magazine security and safety check by procedure under OPNAVINST 8000.16: temperature and humidity logging, stowage compliance, sprinkler operability, access controls — and recognize what "abnormal" looks like before the LPO has to point it out.
• 03Perform PMS (Planned Maintenance System) on torpedo launching system components and handling equipment: MRC-driven steps, tool control, equipment-log entries, and LPO sign-off — clean enough that QA does not return it.
• 04Account for every torpedo, every component, and every associated controlled item on the AA&E custody record — serial-number reconciliation, sign-out, sign-in — with zero discrepancies at watch relief.
• 05Demonstrate safe torpedo handling procedures to NAVSEA OP 4 and OPNAVINST 8000.16 standards in training evolutions — no improvisation near live ordnance, ever.
• 06Meet the Navy Physical Readiness Program standard under OPNAVINST 6110.1 every cycle — weapons-handling work is physical, and the TM division watches who can carry the load underway.

• —OPNAVINST 8000.16 series — Torpedo Systems Safety Policy; the safety governance you operate inside the moment you step into a torpedo magazine or handle a weapon.
• —NAVSEA OP 4 — Ammunition and Explosives Afloat; the explosives-safety rules that govern every torpedo evolution at sea.
• —OPNAVINST 5530.13 series — Department of the Navy Arms, Ammunition, and Explosives (AA&E) Physical Security; the custody and access-control standards governing the torpedo magazine and every weapon you sign for.
• —OPNAVINST 4790.4 series — Ships' 3-M Systems Procedures Manual; every PMS maintenance action you log runs inside this program from your first evolution.
• —NAVPERS 18068 Vol II — Manual of Navy Enlisted Manpower and Personnel Classifications; read the TM-rate NEC entries so the C-school and NEC conversation is not a surprise.
• —NWAE Bibliography for Advancement (BIB) for TM3 cycle — pull the current BIB from MyNavyHR / NETC and start building a study plan before the advancement window closes.

• —TM-rate PQS complete and signed on the LCPO's timeline — including every magazine and torpedo-handling watch qualification, not just the convenient ones.
• —Torpedo magazine and handling-system watch qualification earned within the command's expected window; the TMFN still unqualified at six months is visible to the department head in a small division.
• —Zero AA&E accountability discrepancies on any custody record you sign — one unaccounted torpedo component or mismatched serial number is not a correction, it is a serious incident that reaches the CO.
• —PMS documentation closed clean on assigned maintenance actions — no return-for-rework on your MRC cards from QA.
• —PRT Good Low or higher; BCA in standard — the torpedo handling system requires physical capability underway, and the division notices who is ready.

• —Logging a magazine check or a PMS action from memory instead of walking each step and reading the MRC. An incorrect or skipped torpedo-magazine temperature or sprinkler check is an explosives-safety finding waiting to surface — with your signature on the log.
• —Treating AA&E accountability as routine. Leaving a torpedo component unsecured, signing a custody line you did not personally verify, or fat-fingering a serial number turns an administrative slip into a lost-ordnance report.
• —Going around the TM2 or TM1 on an ordnance or handling question. The explosives-safety chain exists because torpedoes and live weapons are unforgiving of improvisation — bypassing it marks you as a sailor who cannot be trusted in the magazine.
• —Letting your PQS slip because the ship is underway and the schedule is full. The busy deployment is exactly where the LCPO identifies who is self-directed — and the eEVAL reflects it.
• —Posting photos from the torpedo magazine, the tube deck, or the launcher on social media. Weapon configurations, stowage, and ship movement are adversary-collection targets, and one public image is a serious incident report with your name on it.

The good TMFN is the apprentice the TM1 sends into the magazine to run the inventory check before a TYCOM inspection, because the count comes back reconciled to the serial number and the PMS log is walked — not pencil-whipped. By month nine the PQS is signed, the magazine and handling-system watch is qualified, AA&E accountability is clean, and the LCPO is starting to talk about what NEC track or C-school the ship needs before the next deployment cycle.

You are a petty officer who signs for torpedoes and walks the magazine on your own watch now. The crow means the TM1 trusts you with ordnance custody and the handling system — and the ship's torpedo readiness is only as good as the maintenance and the accountability you personally own.

You own a section of the ship's torpedo maintenance bill — the torpedo launching system (tubes, breach mechanisms, impulse charges), the associated handling and stowage equipment, and a portion of the AA&E record — and you execute scheduled maintenance under the TM2 or TM1's supervision. That means running MRC-driven PMS on launching tubes, torpedo handling pallets, impulse cartridge stowage gear, and associated weapons-handling components, then standing magazine watches independently and conducting the security, temperature, and safety checks by procedure during underway operations. You are now a custodian on the AA&E record — you sign for weapons, you account for components, and you brief the new TMFN on why the magazine check is non-negotiable and why "I thought it was close enough" is not an answer in this space. Because TM is a recently re-established rating (NAVADMIN 225/19, 30 September 2019), the community's NEC and C-school pipeline is still maturing — pull the current NEC source-rating NAVADMIN from MyNavyHR before quoting any specific NEC code, because the pipeline has evolved since the rating was re-established.

• 01Execute a PMS MRC on a torpedo launching system component or torpedo handling/stowage equipment and document the action in the ship's 3-M system without a return-for-rework from QA.
• 02Stand a torpedo magazine and handling-system watch independently: custody control, round and component accountability, temperature and humidity checks, sprinkler checks, access-log reconciliation — nothing open at watch relief.
• 03Conduct a torpedo launcher impulse-charge lot-number accountability check and a magazine stowage-compatibility review under NAVSEA OP 4 and OPNAVINST 8000.16, identifying any stowage non-conformance before the LPO has to find it.
• 04Identify and report a torpedo launching system fault — tube latch, breach mechanism, impulse-charge stowage discrepancy, hydraulic fault on a handling system — with the correct technical language and reporting chain, before the watch supervisor has to prompt you.
• 05Reconcile AA&E custody to the serial number with zero discrepancies at every turnover — and know the reporting chain the instant a count does not match, because "find it quietly" is not an answer in this rate.
• 06Mentor TMFN personnel on PQS line items, magazine safety checks, and custody procedures — because the TM division is small, and the TM3 who does not pull the TMFN up is the TM3 the chief notices.

• —OPNAVINST 8000.16 series — Torpedo Systems Safety Policy; the governance for every torpedo-system evolution you run as a custodian, not just a watchstander.
• —NAVSEA OP 4 — Ammunition and Explosives Afloat; the explosives-safety standard for every magazine check and ordnance handling evolution.
• —OPNAVINST 5530.13 series — AA&E Physical Security; you are now a custodian on the record, not just a signature in the log.
• —OPNAVINST 4790.4 series — Ships' 3-M Systems Procedures Manual; the maintenance program you execute every evolution inside.
• —NAVSEA torpedo technical manuals for your ship's installed systems (the TM series governing your platform's launching and handling equipment) — your LPO assigns the volumes covering your work center.
• —NAVPERS 18068 Vol II + current NEC source-rating NAVADMIN — read the TM-rate NEC entries and pull the current cycle before quoting any NEC code; and the NWAE BIB for TM2 cycle from MyNavyHR / NETC.

• —NWAE for TM2 prep on the LCPO's timeline — the TM3 who walks into the exam cold watches the advancement slate from the maintenance bench, and in a small community the bench is short.
• —Zero AA&E accountability discrepancies on any custody record you own — one unreconciled torpedo component or serial-number mismatch is a serious incident, not a finding you talk your way out of.
• —QA-clean 3-M documentation: zero return-for-rework on your closed maintenance actions over a deployment cycle — one return patterns, and in a small division the pattern is visible immediately.
• —Torpedo magazine and system watch qualified on all assigned watchstations; Surface Warfare device in progress or earned.
• —At least one NEC pipeline conversation with your LCPO on record — the TM3 without a documented direction is the one the detailer fills a billet with.

• —Closing a torpedo-system PMS MRC without performing every step. An incomplete maintenance action on a launching tube or impulse-charge stowage system is not a paperwork problem — it is a casualty waiting to surface during a live exercise, and the 3-M system traces the last signature.
• —Signing an AA&E custody line or a serial-number reconciliation you did not personally verify. Torpedo components and associated ordnance are controlled items; a fraudulent custody entry is a JAGMAN — and in a small rating, everyone knows who signed.
• —Cutting a corner on a torpedo magazine safety or sprinkler check because the ship is busy. The magazine is full of live ordnance; a skipped temperature or sprinkler check is the OPNAVINST 8000.16 finding the inspection team is looking for, under your signature.
• —Treating impulse charges as less serious than the torpedo itself. Impulse charges are explosive ordnance; the same AA&E accountability and explosives-handling discipline applies — a casual count or a corner cut on stowage compatibility is the same problem in a smaller package.
• —Letting OPSEC discipline slip around the torpedo systems. Tube configurations, stowage, loading sequences, and exercise timelines are adversary-collection targets; one casual comment or photo ends careers, and the Torpedo Division chief will hear about it by morning.

The good TM3 is the custodian the TM1 trusts with the magazine key on deployment, because the AA&E count reconciles to the serial number every turnover, the PMS closes clean at QA, and the TMFN on the section is progressing on the timeline the LCPO set — not the timeline the TM3 invented. The chief is already mentioning his name for the next TM2 advancement slate and the NEC pipeline the ship needs before the next workup.

You are the working senior TM on the maintenance bench, in the magazine, and on the tube deck. The TM3s call you LPO whether the watchbill says so or not, the weapons chief is mentoring you toward anchors, and the ship's torpedo readiness and AA&E integrity ride on whether your section runs clean.

You run a section of the ship's torpedo maintenance — the launching system work center, the magazine and ordnance handling program, or the torpedo test and maintenance section — and you are the senior technician who either owns the fault diagnosis or reviews the TM3's work before it goes to QA. On a DDG mid-workup, that means fault-isolating a torpedo launching system hydraulic or impulse-charge discrepancy before a live exercise, reviewing a magazine configuration for stowage-compatibility against the NAVSEA OP 4 requirements, or running a torpedo-handling evolution onto a barge under explosives-handling procedure with two TM3s and a TMFN watching how you do it. You are the armory custodian of record for a portion of the ship's AA&E — you own the serial-number reconciliation, the component accountability, and the access controls, and you report it up the chain the instant a count does not match. You train and qual-sign two to four TM3s and TMFNs, build the section's training plan, and write the section's contribution to the weekly weapons readiness brief. The community is small and recently re-established — there are fewer TM1s on the Navy's books than in most weapon-system rates, which means the TM2 who performs above expectation is visible earlier in the advancement conversation. Pull the current NEC source-rating NAVADMIN before quoting any specific NEC code; the TM pipeline has evolved since NAVADMIN 225/19.

• 01Own a torpedo system fault from write-up through fault isolation through corrective action on the launching system, impulse-charge stowage gear, or torpedo handling equipment — system back in readiness status with 3-M documentation closing clean at QA before the next evolution.
• 02Run the section's AA&E accountability as a senior custodian: serial-number reconciliation, component count, access-list control, custody turnover — and execute the report-it-now reflex when a discrepancy surfaces, every time.
• 03Run a section training plan that keeps TM3s progressing on PQS, NWAE study, and practical proficiency without requiring the LCPO to track every milestone.
• 04Review TM3 maintenance and custody documentation before QA or the weapons officer sees it — catch the incorrect MRC step, the missing reference, the unreconciled count — so the section's rework and discrepancy rate stays below the command average.
• 05Brief a torpedo-system discrepancy or a magazine safety issue to the Weapons Officer, Combat Systems Officer, or Torpedo Officer in terms the watch-section officer understands: what the system was doing, what the fault indicates, the fix timeline, and the safety implication.
• 06Mentor TM3s and TMFNs on the NEC pathway, NWAE preparation, and the reality of the advancing TM community — including honest advice about how small the community is and what that means for advancement timing and billet choices.

• —OPNAVINST 8000.16 series — Torpedo Systems Safety Policy; at TM2 you own the safety posture of the section, not just your own watch.
• —NAVSEA OP 4 / NAVSEA OP 5 and OPNAVINST 8020.14B — explosives-safety governance you are accountable for at the section level.
• —OPNAVINST 5530.13 series — AA&E Physical Security; you own the custody program at the section level including the access-list and reconciliation provisions you enforce on your TM3s.
• —OPNAVINST 4790.4 series — Ships' 3-M Systems Procedures Manual; the program your section runs maintenance inside, including the QA provisions you enforce.
• —NAVSEA torpedo technical manuals for your ship's installed systems — at TM2 you own the technical content, not just the procedure steps your TM3 follows.
• —NAVPERS 18068 Vol II + current NEC source-rating NAVADMIN, and the NWAE BIB for TM1 cycle — you mentor packets and build study plans off the current cycle, not a version two years out of date from before the rating re-establishment.

• —NWAE for TM1 prep on the LCPO's timeline; in a small community the TM2 who is not advancing on schedule is visible to the weapons department head.
• —Zero AA&E accountability discrepancies attributable to your section over a custody cycle — the TM2 custodian who loses track of a torpedo component or serial number does not stay a TM2 for long.
• —Section QA rework rate at or below command average — your initials are on the documentation your TM3s produce after you review it.
• —NEC awarded or in-pipeline; Surface Warfare device pinned; PRT Good Medium or better, BCA in standard.
• —eEVAL trait average and ranking that supports an EP or MP recommendation; your LCPO knows your ranking before the board reads it.

• —Rubber-stamping TM3 maintenance or custody documentation without actually reading it. Your initials are the standard; if QA or the AA&E inspection finds the error on a closed MRC or an unreconciled custody line that you reviewed, you own the finding.
• —Chasing a torpedo-system fault with parts replacement instead of procedure. An intermittent launching-system or impulse-charge stowage fault that keeps coming back because the fault isolation was abbreviated costs the supply chain, drags the weapons readiness brief, and puts the section in a QA review.
• —Letting AA&E access lists or custody turnovers drift because "everyone in the division knows everyone." The access list is a physical security control; a stale list or a sloppy turnover is the OPNAVINST 5530.13 finding that surfaces under your name.
• —Cutting corners on explosives handling during an ordnance evolution because the schedule is tight. Live torpedoes and impulse charges do not negotiate with the ops schedule; the OPNAVINST 8020.14B safety assessment finds the shortcut under your name, and the consequence of getting it wrong is not a writeup.
• —Going around the LCPO to the Weapons Officer on a readiness or personnel issue. The weapons chain runs through the chief; the command master chief hears about it the same watch rotation, and the Chief packet feels it at the next ranking.

The good TM2 is the technician the Weapons Officer calls when the torpedo launching system writes up a hydraulic fault before a live exercise and the clock is running, because the fault diagnosis is methodical, the 3-M documentation closes clean, and the system is either back up with a real fix or correctly reported down for a real reason. His AA&E custody reconciles to the serial number every turnover, his magazine safety program runs to standard, his TM3s are advancing on schedule, and the LCPO is mentioning his name for the next TM1 advancement slate.

You are the LPO. The chief is editing your Chief packet; the Weapons Officer knows your name before he calls the chief; the TM2s and TM3s read the torpedo division's readiness standard and whether the AA&E accountability is real off how you carry the work center at quarters.

You are LPO of the torpedo work center — running 6-15 TMs on a surface combatant and owning a piece of the ship's weapons readiness and AA&E integrity from the deckplate up. You are the senior torpedo-systems custodian on the AA&E record, which means a discrepancy is your name at the captain's mast even when another sailor signed the custody line. You write four to six eEVALs per cycle for TM2s and TM3s that shape the next NWAE advancement slate. You build the division's training plan, defend the torpedo readiness metrics at the weekly maintenance management board (system availability, deferred maintenance, PMS completion, AA&E posture under OPNAVINST 8000.16 and OPNAVINST 5530.13), run the torpedo magazine and explosives-safety program to OPNAVINST 8020.14B standard, and mentor at least one TM a year toward an advanced NEC pipeline, a commissioning program (LDO/CWO ordnance or surface warfare), or the civilian and federal market. Because TM is a small and recently re-established community, the TM1 at a fleet squadron is one of the most visible senior petty officers in the rate — what you do here follows you to the Chief board in a community where everyone knows everyone. The Chief packet conversation is no longer theoretical; your LCPO is editing your record, your eEVAL profile is built across the year, and the Surface Warfare device is a floor, not a ceiling.

• 01Run a torpedo work-center training plan that produces qualified, NEC-progressing, NWAE-advancing TMs without the LCPO tracking every milestone — because in a small division, the LPO who needs to be tracked is the problem.
• 02Own the ship's torpedo magazine and AA&E accountability program as the senior custodian — inventory reconciliation, access-list control, custody turnovers, no-notice spot counts — clean at every inspection and command self-assessment.
• 03Defend the division's torpedo readiness metrics — PMS completion, deferred maintenance count, system availability, magazine safety posture under OPNAVINST 8000.16 and OPNAVINST 8020.14B, AA&E accountability — at maintenance-management-board level without the Weapons Officer rewriting your numbers.
• 04Run the torpedo magazine and explosives-safety program to OPNAVINST 8020.14B and NAVSEA OP 4 standard, including the explosives-safety self-assessment that any TYCOM or NAVSEA inspection will verify.
• 05Operate as the senior TM technical voice during a live exercise, a launching-system casualty, an ordnance onload/offload, or a TYCOM / INSURV weapons inspection — including the call to brief the department head when the ship's torpedo readiness has genuinely shifted.
• 06Mentor a TM2's NWAE cycle, NEC pipeline packet, or LDO/CWO commissioning packet from idea to selection — and counsel honestly, because in a small community the TM1 who sends sailors down the wrong path is remembered for it.

• —OPNAVINST 8000.16 series — Torpedo Systems Safety Policy; you are fluent across the safety governance and you own the program at the LPO level.
• —OPNAVINST 8020.14B — Navy Explosives Safety Management Program, with NAVSEA OP 5 and NAVSEA OP 4; the explosives-safety governance you run the magazine inside.
• —OPNAVINST 5530.13 series — AA&E Physical Security; you own the custody, access, and accountability provisions from the LPO chair.
• —OPNAVINST 4790.4 series — Ships' 3-M Systems Procedures Manual; fluent across QA, tool control, and maintenance documentation provisions you enforce.
• —NAVSEA torpedo technical manuals for your ship's installed systems — you are the technical authority the Weapons Officer signs behind on work-center torpedo-system discrepancies.
• —NAVPERS 18068 Vol II + current NEC source-rating NAVADMIN and MILPERSMAN articles on enlisted promotions, retention, and NJP — you are now in the room for the conversations that happen at TM1 visibility.

• —Chief board packet under construction with the LCPO's eye on every line; eEVAL profile defensible at department head and CO level; Surface Warfare device pinned and current.
• —AA&E accountability posture, torpedo magazine explosives-safety self-assessment, and system readiness defensible at Weapons Officer and CO level every cycle — because one lost torpedo component erases everything else on the record.
• —Work-center QA rework rate and calibration compliance defensible at command level, every cycle.
• —Advanced NEC maintained and current; verify currency requirements against the current source-rating NAVADMIN, not from memory — the TM pipeline has changed since 2019.
• —Pipeline output — advanced NEC, commissioning, federal civilian, or defense-contractor credential path — producing at least one selectee or completion per year from your work center.

• —Briefing torpedo readiness or AA&E accountability numbers you have not personally validated against the 3-M system and the custody record. The Weapons Officer catches the discrepancy once and your Chief packet feels it permanently.
• —Letting a senior TM2 carry the magazine custody or the explosives-safety program because "he is your guy." When he transfers mid-deployment, the gap — a stale access list, an unreconciled component count — surfaces under the LPO's name at the next inspection.
• —Treating the torpedo magazine explosives-safety self-assessment as a paperwork drill. The magazine is the highest-consequence space in the weapons department on a surface combatant; a self-assessment you signed without walking is the OPNAVINST 8020.14B finding the inspector reads back to you.
• —Going around the LCPO to the Weapons Officer or the XO on a personnel or readiness issue. The chain runs through the chief; the command master chief hears about it the same watch, and the next Chief board reads the pattern.
• —Assuming that because TM is small, the standards are informal. The rating was re-established for a reason, the NAVSEA and TYCOM oversight community is watching how it builds its culture, and the TM1 who lets standards slip in a visible small community is the one the Chief board remembers.

The good TM1 is the LPO the LCPO trusts to run the torpedo work center through a deployment without daily check-ins. His AA&E accountability and torpedo magazine safety posture brief without caveats, his eEVALs pick TMs above expectation, his work-center pipeline produces advanced NEC holders or commissioning packets the Weapons Officer can brief without rewriting, and the Chief board packet he sits with is the one the LCPO has been building for two years.

You are a Chief in one of the Navy's smallest and most recently re-established weapon-system ratings. The gold-fouled anchors mean the goat locker is yours, and the torpedo division's readiness, AA&E integrity, and explosives-safety culture are now your direct accountability — not something you delegate to the LPO and check at the brief.

The job changes more between TM1 and TMC than at any other promotion in the rate. As LCPO of the torpedo division — running 8-20 TMs on a surface combatant, a DESRON weapons and ordnance staff, or a NAVSEA / TYCOM weapons-systems schoolhouse billet — you own enlisted torpedo execution and AA&E integrity from the deckplate to the commodore's readiness brief. You are the command's senior enlisted authority on the torpedo magazine, the launching systems, and explosives safety; when the inventory does not reconcile or the magazine self-assessment fails, the CO is calling you. You write Chief-quality eEVALs that shape the TM1 and future Chief slate for the rate; you sit at the maintenance management board and the explosives-safety review as the senior enlisted torpedo voice; and you walk the magazine, the work center, and the tube deck during a surge or a TYCOM / INSURV weapons inspection looking for the broken procedure before the inspector does. Because TM was re-established in 2019, the community is still building its Chief's Mess traditions and its senior enlisted institutional culture — which means the TMC who stands up well at the goat locker and enforces rigorous magazine and accountability standards is not just running a division, he is writing the playbook for the next generation of TMCs.

• 01Run an LCPO's division of TMs — accountability, training, readiness, discipline, family-readiness, finance, and long-term career counseling — with a weekly cadence the Weapons Officer and department head can predict and trust.
• 02Own command-level torpedo magazine and AA&E accountability to OPNAVINST 8000.16, OPNAVINST 5530.13, OPNAVINST 8020.14B, and NAVSEA OP 4 standard — the inventory reconciliation and the explosives-safety self-assessment that pass an inspection without senior-enlisted-attributable findings.
• 03Defend the division's torpedo readiness metrics, QA posture, magazine safety posture, and system availability at command-level board without your numbers being rewritten by the Weapons Officer.
• 04Walk a real-world live-fire exercise workup, INSURV weapons inspection, ordnance handling evolution, or casualty as the senior enlisted torpedo voice on scene — and carry the AAR the Weapons Officer briefs to the commodore.
• 05Mentor four to six TM1s into Chief-board-competitive candidates; mentor at least one LDO/CWO packet, STA-21 application, or NAVSEA / defense-contractor credential path to completion per year.
• 06Translate NAVSEA, TYCOM, and OPNAV torpedo-systems and explosives-safety policy into deckplate decisions the TMs rehearse without the manual in hand.

• —OPNAVINST 8000.16 series — Torpedo Systems Safety Policy; the governance you own and defend at command level, and the standard the TYCOM holds the LCPO accountable to.
• —OPNAVINST 8020.14B — Navy Explosives Safety Management Program, with NAVSEA OP 5 and NAVSEA OP 4; the explosives-safety governance you run the magazine and ordnance handling program inside.
• —OPNAVINST 5530.13 series — AA&E Physical Security; the custody and accountability program you own at the LCPO level.
• —OPNAVINST 4790.4 series — Ships' 3-M Systems Procedures Manual; QA, tool control, and documentation standards you enforce at the division level.
• —NAVSEA torpedo technical manual library for your ship's platform and ordnance baseline — you are the LCPO the TM2s and TM1s bring the policy question to.
• —MILPERSMAN, CPO 365 / Chief's Mess transition guidance, and the Senior Enlisted Academy reading list — the goat locker and the wardroom both hold you to this standard, and in a small re-established community you are building the TMC tradition as you go.

• —CPO Academy / Chief's Mess transition complete; standing as a Chief in the mess and at the deckplate — not a Chief in title only — in a community that is still writing its own Chief-level institutional norms.
• —AA&E accountability and torpedo magazine explosives-safety posture defensible at Weapons Officer and CO level every cycle — zero lost torpedoes or components, because at TMC this is the single standard that defines you.
• —Division QA rework rate, calibration compliance, and INSURV / TYCOM weapons inspection posture defensible at command level every cycle.
• —Pipeline producing 1+ LDO/CWO packet, STA-21, advanced NEC, or defense-contractor / federal-civilian credential completion per year — and the Weapons Officer can name them.
• —Zero Chief-level integrity incidents — falsified custody or 3-M records, explosives-safety negligence, fraternization, financial mismanagement, OPSEC breach. One ends the career permanently, and in a small community it echoes throughout the rate.

• —Mistaking the goat locker for a private club. The mess is a working leadership platform, and in a small and recently re-established rating, the Chiefs who build a credible mess build the culture of TMC for the next decade.
• —Letting a TM1 LPO run a degraded magazine or AA&E accountability program because he is "your guy" or "almost a Chief." The discrepancy or the explosives-safety drift surfaces under your name at the inspection.
• —Stopping personal technical study because "I am a Chief now." Torpedo system policy, ordnance baseline configurations, and NAVSEA safety guidance evolve; the TM2 just off a current C-school or fresh from NAVSEA school will outbrief you at the board if you stop reading.
• —Treating the torpedo magazine self-assessment or the AA&E spot count as something to schedule around. You walk it yourself; the consequence of a magazine you signed off without walking is not a writeup — it is the worst day the ship will ever have.
• —Going public with disagreement with the Weapons Officer, CSO, or CO. The disagreement happens behind closed doors; you walk out aligned. The goat locker enforces this without the wardroom asking.

The good TMC is the LCPO the CO calls by name and the goat locker defends in the mess. His AA&E accountability is unbroken, his torpedo magazine safety posture is the one the inspection team cites, his weapons readiness metrics brief without caveats, his TM1s pick up Chief, and his deckplate rigor in the magazine matches his at-liberty posture. Because the TMC community is small and recently re-established, the TMC who holds the standard without shortcuts is not just running a division — he is writing what it means to be a TMC.

You are the senior enlisted torpedo and ordnance voice in a surface warfare command, a DESRON weapons staff, or a NAVSEA / TYCOM schoolhouse. The TM community is small, recently re-established, and still building its senior enlisted institutional culture — which means what you do at TMCS and TMCM defines the standard for everyone who comes after you.

As TMCS or TMCM you run the senior enlisted torpedo and ordnance posture for a surface warfare group or DESRON staff, a large combatant as Command Master Chief (CMC), a Center for Surface Combat Systems schoolhouse at Yorktown (where TM "A" School lives), a NAVSEA or TYCOM weapons staff billet, or a naval weapons station or ammunition depot. You write fewer eEVALs but they are the ones that pick the next Chief and Senior Chief slate for a rate that, as of 2019, is still growing its leadership pyramid from the bottom up. You sit at command-team sync as the senior enlisted voice on every torpedo and ordnance decision — NEC programming, C-school quota distribution, retention, AA&E accountability compliance, explosives-safety culture, and discipline. You are the command's senior accountable conscience on the torpedo magazine and the ordnance inventory: a systemic accountability or explosives-safety failure on your watch is a flag-officer conversation. Because TM re-established in 2019, TMCS and TMCM are not roles with decades of community norms to fall back on — the standards, the Chief's Mess traditions, and the pathway to Master Chief are being built in real time by the first cohort of senior enlisted TMs. That is either a burden or the best opportunity in the rate, depending on the sailor who holds the seat.

• 01Run a senior-enlisted command climate across a torpedo division or weapons staff that produces credentialed TMs, advanced NEC selectees, LDO/CWO commissions, and STA-21 accessions — in a community small enough that every outcome is visible.
• 02Own command-level torpedo magazine and AA&E accountability culture as the senior enlisted conscience — the inventory and explosives-safety posture that survives an inspection with zero senior-enlisted-attributable findings and zero lost ordnance.
• 03Brief the CO, Weapons Officer, commodore, or TYCOM on enlisted torpedo readiness and systemic risk — AA&E posture, magazine-safety trend, NEC billet fill, retention curve, training throughput — in language the flag officer can defend at the next echelon without rewriting.
• 04Sit on Chief selection board panels, command CMC slates, and senior-enlisted credentialing reviews with the discipline and confidentiality the convening authority requires.
• 05Translate NAVSEA / OPNAV-led torpedo-systems, ordnance modernization, and explosives-safety strategy into enlisted talent management, NEC programming, and training decisions at the unit and across the rate — in a community that is still building the pipeline capacity to execute it.
• 06Run a real-world TYCOM weapons inspection, INSURV weapons portion, serious ordnance casualty, or explosives-safety incident as the senior enlisted torpedo voice on scene — and carry a Red Cross notification or casualty follow-through with the dignity the family and the deckplate require.

• —OPNAVINST 8000.16 series and OPNAVINST 8020.14B, with NAVSEA OP 5 / NAVSEA OP 4 — the torpedo-systems and explosives-safety governance you are cited from more often than you cite, and the standard you defend at the command roll-up.
• —OPNAVINST 5530.13 series — AA&E Physical Security; the custody and accountability program you own across the command.
• —OPNAVINST 4790.4 series and the NAVSEA torpedo technical manual library for your platform baseline — you are the senior enlisted technical authority, not the procedure-step reader.
• —COMNAVSURFLANT / COMNAVSURFPAC TYCOM maintenance and ordnance instructions and current NAVADMINs — pull each one as it drops; the TM community is small enough that the NEC and billet landscape can shift meaningfully with a single NAVADMIN.
• —MILPERSMAN and the Senior Enlisted Academy (SEA, Naval War College, Newport RI) reading list, plus NAVADMIN 225/19 and any follow-on re-establishment guidance — you understand the historical and regulatory context of the rating you lead.
• —Defense-contractor torpedo-systems and weapons-handling technical roles, naval weapons station and ammunition depot civilian billets, and federal-civilian explosives-safety / GS-series position descriptions — the post-Navy market the TMs you mentor will enter.

• —Senior Enlisted Academy (SEA) fellowship or equivalent senior-enlisted PME complete before competing for command CMC or Force Master Chief slate.
• —Command-level torpedo weapons inspection (INSURV weapons portion, TYCOM Operational Readiness Evaluation, or explosives-safety inspection) passed without senior-enlisted-attributable findings during your tenure — and an unbroken AA&E accountability record.
• —Pipeline producing 1+ LDO/CWO commission, STA-21, advanced NEC, or defense-contractor / federal-civilian credential per year from your command — in a community small enough that the TYCOM notices when the pipeline stalls.
• —eEVAL profile the senior rater can defend at command and TYCOM level — your rated chiefs are picking up Senior Chief and Master Chief on schedule.
• —Zero senior-enlisted-level integrity incidents — falsified custody or 3-M records, explosives-safety negligence, financial, fraternization, OPSEC. One ends the career permanently, and in a small re-established community it also damages the institutional credibility of the rating itself.

• —Pretending to be the current technical authority on a torpedo-system baseline or ordnance configuration you are a version behind. Senior TMs lose credibility the first time the TM2 from the most recent C-school has to correct the TMCM in a readiness brief — own the gap and own the senior TM who fills it.
• —Letting a Chief-led magazine or AA&E accountability program drift because "the TYCOM will catch it." You own enlisted torpedo execution at the command roll-up; the finding lands under your name, and the real-world consequence of a magazine failure on a surface combatant is measured in lives, not points.
• —Treating the LDO/CWO, STA-21, NAVSEA, or defense-contractor mentoring conversation as transactional. In a small community, the TMs you commission and credential are building the surface-warfare officer corps and the ordnance industrial base that the Navy depends on — and in 20 years they will remember whether the TMCM was investing or going through the motions.
• —Going public with disagreement with the CO, Weapons Officer, or commodore. Take it to the office. Walk out aligned. The goat locker and the wardroom both enforce it, and at TMCM the standard is absolute.
• —Confusing the transition to retirement with the job. The deckplate is watching until the last formation — and the TM community is small enough that the TMCM who checked out early is remembered at every advancement board for the next decade.

The good Master Chief Torpedoman's Mate is the senior enlisted torpedo voice the CO, commodore, and TYCOM name without thinking, and the figure the Chief's Mess at every torpedo division cites as the standard. His command's AA&E accountability is unbroken and his torpedo magazine safety posture is what the inspection team quotes across the waterfront; his pipeline produces LDO commissions, STA-21 accessions, advanced NEC holders, and defense-industry credentials; and his rated chiefs pick up Senior Chief and Master Chief on schedule. Because TM was re-established in 2019, the TMCM who holds the standard without shortcuts is not just closing out a career — he is writing the permanent record of what it means to lead in this rating.
