HEADS UP

HT 'A' School at NETC Great Lakes is where you learn to strike an arc and read a pipe drawing. The ship does not care which one you prefer — the DCA wants both, and the first class will find out in week two which half you are faking. Get the basic welder qualification signed before deployment. Everything else grows from that credential.

The Honest MOS Read
You checked in as an HTFN — Hull Maintenance Technician Fireman — which is the Navy's polished way of saying you are the apprentice who gets the grinding wheel, the chipping hammer, and the hottest space on the ship. HT 'A' School at Great Lakes runs you through GTAW (TIG) and SMAW (stick) welding fundamentals, pipe-system theory, basic damage-control procedures, and the 3-M Planned Maintenance System before sending you to your first command. The instruction is real, the credential matters, and none of it fully prepares you for the first time you are standing in a bilge at 0200 with a firemain leak spraying your face trying to remember what the P&ID said the isolation valve was. The assignment fork lands you in one of a few places: R-Division (Repair Division) on a surface combatant — a DDG, CG, or LHD — where you are the hull and structural maintenance team; the repair shop on a tender or afloat repair platform, where you run production-level welding and pipefitting on other ships; or a shore-side intermediate maintenance activity (IMA) where you work alongside civilian contractors on a depot-scale work package. The ship is the formative assignment. A tender teaches production tempo. An IMA teaches process. The ship teaches all of it under pressure. The first six months at the deckplate are almost entirely 3-M Planned Maintenance System work — Maintenance Requirement Cards (MRC cards) that tell you exactly what to inspect, lubricate, adjust, or replace, in what order, with what tools, and how to log the outcome. The HTFN who pulls an MRC, reads it, executes it in sequence, and logs it correctly without skipping steps is the HTFN the LPO sends alone. The HTFN who back-dates cards, skips safety checks, or logs incomplete evolutions as complete is the HTFN whose name goes on the TYCOM 3-M spot-check discrepancy report. Damage control is the other half of the job, and it is not a separate career track — it is the same job viewed from a different angle. As an HT you maintain the hull, the pipes, and the DC equipment; when the ship takes damage, you are the sailor who knows where the isolation valves are, which repair locker has the right plugs, and how to weld a temporary patch on a flooded compartment. DC PQS qualification line items close in parallel with weld qualification — the first class running your PQS board is watching whether you treat them as two separate things or one coherent job. Weld qualification at this level starts with 1G flat-position SMAW to NSTM Chapter 074 and AWS D1.1 visual-inspection criteria. The Welding Inspector is the authority — not your opinion, not the second class who trained you. The Inspector reads the weld with a flashlight and a weld-inspection gauge; porosity, undercut, overlap, and cracks fail on sight, and the HT who thought the weld was 'close enough' is the HT re-prepping the coupon on the next available day. Get the 1G signed. Then pursue 2G, 3G, 4G in sequence as the LPO schedules you. The welder qualification record is the first credential that follows you from ship to ship. The Navy Enlisted Advancement System (NWAE) for HT3 is on the horizon faster than you expect. The BIB — Bibliography for Advancement Exam Study, published per cycle by NETC on MyNavyHR — is the test map. Pull it the day you check in. Start the study log. The HTFN who walks into the HT3 advancement exam without a documented study habit is the HTFN watching the slate from the bench.
Career Arc
  • 01RTC Great Lakes — Navy boot camp, ~8-10 weeks.
  • 02HT 'A' School, NETC Great Lakes — welding fundamentals, pipe theory, DC basics, 3-M orientation.
  • 03First assignment: R-Division on a surface combatant, tender production shop, or IMA.
  • 04Basic welder qualification (1G SMAW) to NSTM 074 / AWS D1.1 — signed by the ship's Welding Inspector before first underway.
  • 05DC PQS qualification and repair-locker watchstander quals on the LCPO's timeline.
  • 06NWAE BIB for HT3 pulled and study log started.
  • 07Advancement to HT3 via NWAE cycle — exam + service record review.
Common Screwups
  • ×Striking an arc without a Hotwork Permit and fire watch in place. One weld in an uncontrolled space and the DCA knows your name before the arc goes cold — and not in a career-positive way.
  • ×Back-dating or skipping MRC steps on a 3-M card. The TYCOM 3-M spot-check inspector does not grade on completion rate; he audits signatures, dates, and step compliance. One falsified card opens a page-11 minimum.
  • ×Going to the barracks the first weekend instead of learning the ship's compartment numbering system. The HTFN who cannot find the repair locker at 0200 during a DC drill is a liability — and the chief notices which one got lost.
  • ×NJP / DUI at the apprentice level. The HT community is small enough that the LCPO at your next command will have already heard. Promotion to HT3 stalls, clearance questions open, and the senior HTs decide early whether you are worth investing in.
  • ×Treating the weld test as a surprise event. The Welding Inspector does not accept partial credit — show up with the technique practiced, the coupon prepped, and the visual criteria memorized.

A Day in the Life

  • 0500Wake up. PT uniform on. Quick check — nothing on your phone from the duty section about a casualty overnight.
  • 0530PT formation on the pier or in the ship's hangar bay. Take accountability for yourself, report to the leading petty officer. Missing accountability is a chain-of-command event before 0545.
  • 0545-0700Unit PT — run, circuit, or swim depending on the week's training plan. HTs are expected to keep up during DC drill sprints; what you do at 0545 is practice.
  • 0700-0900Hygiene, breakfast at the galley. Change into utilities. Morning quarters at 0745 in the shop or on the quarterdeck — today's work assignments and any safety announcements.
  • 0900-1130Work call. The LPO hands out MRC cards and work orders. Today you are running a scheduled inspection on the bilge-pump PMS card and assisting the HT3 on a pipe-flange replacement in the aft machinery space.
  • 1130-1300Knock off work. Wash hands, stow tools, log any maintenance actions in OMMS-NG before heading to the galley. The LPO checks who logged and who forgot.
  • 1300-1500Afternoon work call. Back to the flange job or assigned to practice welds in the shop under the HT2's supervision. If the work order is waiting on parts, you are cleaning the shop or doing PQS study in the work center.
  • 1500-1630Secure work, clean spaces, return tools to the tool locker with a physical count. Afternoon quarters — next day's schedule, any additional duties.
  • 1630Liberty or duty section. If you are the HTFN in the duty section, you are standing the DC roving watch — two-hour rotation — until 0700 tomorrow.
  • 1700-2000Study block. BIB material for HT3, NSTM Chapter 074 sections relevant to next week's weld test, or PQS workbook. Not optional if you showed the LPO a study schedule.
  • 2000-2200Personal time. On a ship in port this means your berthing compartment, the MWR, or off-ship liberty. Lights out at a reasonable hour — the DC drill at 0200 that breaks the fire-main fitting in frame 44 does not care about your sleep schedule.
  • Underway watchbillAdd DC repair-locker phone-talker watches to the rotation — typically 4 hours on, 8 hours off during general operations. During GQ drills, you man the locker and execute the drill assignment. The HT who mans the locker late because he did not know the route is the example the chief uses at the next all-hands DC training.

Weekly Cadence

The Monday-through-Friday rhythm in R-Division on a surface combatant runs on the work-center schedule and whatever the engineering department's current priority is. Monday starts with morning quarters, weekly safety brief, and distribution of the week's PMS MRC schedule. The HTFN gets the assigned cards for the week — some are solo work, some are assist work under a petty officer. The bulk of the work week is MRC card execution and any corrective maintenance (CSMP work orders) the division has open. Tuesday and Wednesday are the production days — if there is a structural repair or pipe job in the work-order queue, those days are where the cutting and welding happen. The HTFN assists the HT3 or HT2 on production work, learns the sequence by watching and asking before touching, and executes the portions the petty officer assigns. Thursday is often the catch-up day for PMS cards that slipped earlier in the week and the day the LPO runs a work-center compliance check. Friday has a cleaning evolution built in — the engineering department runs a clean-sweep-down before the weekend, and R-Division cleans the shop, the repair lockers, and the welding bays. The other constant is DC drill cadence. Ships run General Quarters drills on a command-directed schedule — typically several times a month underway and at least once in port. The HTFN stands whatever watchstation the watchbill assigns and executes the drill assignment. The drill performance is a data point the DCA reads monthly. Field days and working parties interrupt the technical work on irregular schedules; when the 1MC pipes 'all hands working party,' you go.

Key Skills — How to Drill Each

  1. 01
    Strike an arc and lay a sound SMAW weld in the 1G flat position to NSTM Chapter 074 and AWS D1.1 visual-inspection criteria — no cracks, no porosity, no undercut.
    Run practice coupons every available day in the shop before you ever book a test date with the Welding Inspector. The technique variables that kill the 1G test are travel speed (too fast = undercut, too slow = overlap), arc length (too long = porosity), and electrode angle (wrong = incomplete fusion). Ask the HT2 to watch your first ten coupons and call out the technique errors in real time — not after you have already drilled the bad habit. When you think you are ready, run five consecutive coupons that pass your own visual inspection before you schedule the Inspector.
  2. 02
    Read a basic pipe-system diagram (P&ID) and trace flow paths in the bilge, firemain, and ballast systems before opening a valve or cutting a flange.
    The ship has NSTM Chapter 505 (Piping Systems) as the system reference, and every pipe system has a P&ID in the engineering drawings library. Get the drawings for your ship's firemain and ballast systems in week one — not when you are standing in front of the valve. Trace the flow path on paper first, then walk the physical system and match every valve in the drawing to its physical counterpart in the space. The HT who opens a valve from memory is the HT who sequences a flooding casualty. The P&ID trace is not optional; it is the job.
  3. 03
    Execute a PMS MRC card completely — preparation, safety checks, work steps, log entry, LPO sign-off — no skipped steps, no back-dated entries.
    Read the MRC card before you touch the equipment — not while you are performing the steps. The MRC has a safety-precautions block for a reason; if it says to de-energize a system before inspection, de-energize it and have the watch supervisor verify the lineup before you open the panel. Log the action in OMMS-NG the same day it is performed. The INSURV inspector's 3-M audit checks date of performance against date of log entry — a card logged a week after execution is a discrepancy even if the work was done correctly.
  4. 04
    Run a damage-control repair-locker inventory: shore-FM plugs, wedges, clamps, blanks, torque wrenches, pipe-patching kits — everything to SOP and logged.
    The locker SOP is a physical list posted inside the locker door. Walk the inventory counterclockwise once per week with a clipboard. Every item you touch gets a physical check — not a visual sweep from the door. Expired AFFF canister dates, missing torque wrench calibration stickers, and unserviceable hydraulic rescue tool components are the three things the DEAST inspection team always finds when the HTFN was doing visual sweeps instead of hands-on checks. When you find a discrepancy, log it in CSMP before you close the locker. Do not wait to mention it to the chief at morning quarters.
  5. 05
    Handle SMAW electrodes, shielding gases, and grinding debris per NSTM Chapter 074 safety requirements — PPE, ventilation, fire watch posted before arc is struck.
    NSTM 074 Section 074-2 covers welding safety requirements including ventilation, PPE, and hot-work fire-watch protocols. The minimum: proper welding helmet shade (SMAW typically shade 10-12 by amperage), hearing protection, leather gloves, spark-proof clothing, and a posted fire watch with a serviceable extinguisher who is watching the weld — not his phone. Confined-space welding adds ventilation requirements and a gas-monitoring check before first arc. The HT who skips any of these because 'it's a quick tack' is the HT in the DCA's office the same afternoon.
  6. 06
    Stand a basic damage-control watchstation — repair locker phone-talker, DC roving watch — and report status by the ship's SORM format without prompting.
    The Station Organization and Regulations Manual (SORM) governs watchstanding procedures and reporting formats on your ship. Study the DC watchstation section before you stand your first watch — not during it. The phone-talker report format is scripted: unit name, watchstation name, status (manned and ready / casualty). Practice the report out loud before the drill. The watch supervisor who has to prompt you for the format the third time in a row is the watch supervisor who writes the HTFN 'not ready for advancement' on the quarterly eval.

Manuals & References — What Chapters Matter

  • NSTM Chapter 074 — Welding and Allied Processes
    This is the HT bible at every paygrade. At the apprentice level you live in Section 074-2 (safety) and Section 074-3 (welder qualification) — know the qualification table, what 1G/2G/3G/4G mean, and what the visual-inspection acceptance criteria are before you book a test date. The Welding Inspector quotes this manual; you should be able to find the relevant section faster than he can.
  • NAVSEA S9086-CH-STM-010 — Hull Structures (Welding and Brazing volume)
    The procedure-specific companion to NSTM 074 for hull and structural repair work. Where NSTM 074 governs the welder qualification and process, S9086-CH-STM-010 governs the specific hull structural repair procedures. The LPO will reference both when assigning you a structural repair job — read the relevant sections before you light the torch.
  • AWS D1.1 — Structural Welding Code – Steel
    The commercial standard that NAVSEA procedures reference. Your Weld Procedure Specification (WPS) is written to AWS D1.1 — know what a WPS is, what it governs (base metal, filler metal, position, preheat, interpass temperature), and what it means when the Inspector says you exceeded the WPS scope. At the HTFN level, 'know what it is and why it exists' is the bar.
  • OPNAVINST 4790.4 series — Ships' 3-M Systems Procedures Manual
    Every MRC card you log and every maintenance action you sign for runs inside this program. Read the 3-M manual's overview section in week one of the ship check-in. The two things you need to understand before your first inspection: the difference between scheduled maintenance (PMS) and corrective maintenance (CSMP work orders), and what OMMS-NG is and how maintenance records are documented.
  • NAVPERS 18068 Vol II — Manual of Navy Enlisted Manpower and Personnel Classifications
    The NEC catalog. Pull the HT-rate NEC entries in the first 60 days and read what each specialty track requires in terms of C-school, weld experience hours, or sea time. The HT who walks into a career-counselor conversation already knowing which NEC path he wants and what the prerequisites are is the HT the LCPO advocates for at the next C-school selection board.
  • NAVSEA OD 45845 — Damage Control
    The platform-agnostic DC reference that governs repair-locker operations, flooding response procedures, and equipment inspection requirements. You are not expected to memorize it at the HTFN level — but you are expected to know where the relevant sections are (Chapter 5 on repair-locker equipment, Chapter 7 on flooding casualty procedures) and to have read the sections that apply to your watchstation before you stand it.

Standards — How to Hit Each

  • Basic welder qualification (1G flat position, SMAW) to NSTM 074 criteria signed by the ship's Welding Inspector before the first underway.
    Book the test date with the LPO early enough that a re-test is still possible before deployment. The test consists of a groove weld coupon in the 1G position that the Inspector evaluates by visual inspection and bend test. Prepare five practice coupons that you would be willing to put in front of the Inspector before you schedule the real test. If the LPO offers a practice test evaluation, take it — the feedback is worth more than another solo practice session.
  • DC-locker PQS and basic repair-locker watchstander qualification on the LCPO's timeline — the HT still unqualified at six months is visible to the DCA.
    Walk the PQS with the senior HT3 or HT2 in your division every two weeks. Never sign your own PQS line items — a qualified petty officer signs each block. The line items that stall HTFN PQS are almost always the practical demonstrations: run the flooding casualty procedure drill, demonstrate knowledge of the repair locker inventory, show you can set up and operate the portable submersible pump. Schedule those demonstrations early; they require a qualified evaluator who is not always available on demand.
  • PRT Good Low or higher; BCA in standard. DC drill hose runs are physical events; the first class notices who can sprint to the casualty.
    The Navy PRT runs under OPNAVINST 6110.1. Train the 1.5-mile run, push-ups, and curl-ups or plank in the six weeks before the test cycle — not the morning of. The HT specifically: damage-control drill sprints in full gear (OBA/EAB donned, hose hauled), firefighting station runs, and repair-locker gear carries are all physically demanding. The HT who falls out during a drill is noticed the same day, and the first class's opinion of your readiness is set in those drills.
  • NWAE study habit established and BIB pulled for HT3 cycle — the advancement exam closes faster than new HTFNs expect.
    Pull the current HT Bibliography for Advancement (BIB) from MyNavyHR / NETC the week you check in. Build a 30-minute daily study log — four days a week, chapter-by-chapter through the BIB references with written notes you can review the week before the exam. Show the LPO the log when he asks. The HTFN who shows up to the HT3 exam with a documented study habit is the one the LCPO signed an advancement recommendation for; the HTFN who crammed the week before is the one watching the slate.
  • Zero 3-M documentation errors attributed to skipped steps or back-dated log entries.
    Log every maintenance action in OMMS-NG the same day it is performed. Never log work you did not personally perform or verify. If you miss a scheduled MRC, report it to the LPO that day — a missed card that is rescheduled is a discrepancy; a missed card that is logged as completed is a falsification. The TYCOM 3-M spot-check pulls random cards and verifies completion dates against work-center scheduling records. One falsified card under your name produces a page-13 entry minimum.

Technical Mistakes — Concrete Consequences

  • Striking an arc on ship structure without a Hotwork Permit and fire watch posted.
    Hotwork Permit violations on a Navy ship are not a counseling event — they are a potential summary court-martial territory. The DCA is notified the same day. The HTFN's name goes on the permit-violation log that TYCOM and INSURV review. The permit program exists because fires at sea kill people; the permit violation tells the command you either did not know or did not care, and neither answer helps your advancement.
  • Opening or closing a valve from memory instead of tracing the line-up on the P&ID.
    One wrong valve in the ballast system sequences a flooding casualty in the space below the valve you just turned. One wrong valve in the firemain creates a pressure surge that blows a weak flange downstream. The P&ID trace takes three minutes; the flooding casualty investigation takes three months and your name is in every paragraph.
  • Logging a weld as complete and within visual criteria when it has visible undercut or porosity.
    The Welding Inspector re-inspects completed welds during INSURV and TYCOM structural inspections. A weld logged as 'visual-pass' that the Inspector rejects produces a discrepancy that traces back to the HTFN who signed the 3-M completion record. The weld gets cut out and re-done at your expense in terms of labor, and the production log shows who called it good the first time.
  • Skipping a MRC step because the equipment 'always passes.'
    The INSURV inspector's 3-M spot-check is a procedural audit, not a pass/fail functional test. A skipped safety step on a passed functional test is still a 3-M discrepancy. The inspector finds it in the step-by-step log review. The entire division fails the spot-check because of one card, and the LPO traces the card to the work center and to the individual.
  • Treating damage-control drills as administratively annoying evolutions to get through.
    DC readiness is a material inspection item — TYCOM CART, DEAST, and INSURV all formally evaluate repair-locker readiness and the watchstander performance in drills. The HTFN who cannot find the locker, cannot operate the equipment, or cannot give a coherent SORM-format report during a graded drill is a data point that goes on the division's readiness assessment. The chief who sees the same HTFN struggle twice has already made a career decision.

Career Decisions at This Rank

  • Which NEC track to pursue (advanced welding, pipe/valve, Navy Diver)
    The HT-rate NEC pipeline is the first real career fork and it opens earlier than most HTFNs realize — you should be in this conversation with the career counselor and the LCPO within the first year. The advanced welding NEC (NEC 4604 or equivalent current code — verify against the current NAVPERS 18068 NEC catalog) keeps you on the structural and production welding track, opens doors on tenders and RMC work, and is the foundation for the AWS CWI credential. The pipe and valve NEC track moves you toward system engineering on larger ships. The Navy Diver path (selected before or during A-school in many cases, but the UBA track is also an enlisted-in-service pipeline) is physically demanding, highly selective, and career-defining if you make it. The honest assessment: pick the track that matches what you actually want to do for the next ten years, not what sounds most impressive at the bar. A motivated HT2 in the pipe-valve track does more for ship readiness than a bored HT2 in the diver track who never wanted to dive.
  • Re-enlistment at first window (typically ~2 years in)
    The first re-enlistment window opens at roughly 17 months before your end of active obligated service (EAOS). The HT rating's retention bonus (SRB) varies by cycle, MOS shortage indicator, and whether you are accepting a school or deployment package. Pull the current NAVADMIN SRB message from MyNavyHR before you sign anything — the bonus structure changes cycle to cycle and the terms of the contract (zone, length, billet restrictions) determine what you are actually agreeing to. The trap at this paygrade: signing the maximum-length contract for the maximum bonus before you have enough information about the rate to know if you want to be here for six more years. A shorter re-enlistment with a lower bonus is not a bad trade if it preserves the ability to make an informed decision at four years.
  • Surface Warfare qualification
    The Surface Warfare Enlisted (SWE) designation requires a multi-stage qualification process on your ship — watchstander quals, PQS completion, oral board, CO endorsement. The SWE device on your chest is a visible credential that the advancement board notices and that the LCPO uses when building the senior-rater ranking for eEVALs. For an HT, surface warfare qualification is not a collateral nice-to-have — it is the expected professional development track for a sailor who is going to spend a career on ships. Start the process in the first year.

How the Seat Varies by Unit Type

  • Surface combatant (DDG, CG)
    R-Division is usually 8-15 HTs on a DDG, and the tempo is production welding plus DC readiness. You work in tight spaces, the DCA is your direct chain-of-command visibility point, and the INSURV clock is always visible. High tempo, real repair work, sea-story-generating experiences. The foundational tour for any HT career.
  • Tender / Afloat Repair (AS, AR)
    Production welding shop environment — you are doing repair work on other ships, not just your own. The work orders are higher volume, the tolerances are more heavily documented, and the NAVSEA technical authority interaction is more frequent. An HTFN on a tender learns production-rate welding and the NAVSEA procedure compliance standard faster than on a combatant.
  • Large-deck amphib or carrier (LHD, CVN)
    Larger R-Division, more complex hull systems, more formal administrative procedures. The sheer size of the ship means the P&ID library and the compartment numbering system take longer to learn. But the DC locker network is more robust and the training infrastructure (damage-control training teams, more senior HTs available) is stronger.
  • Intermediate Maintenance Activity (IMA) shore-side
    Shore-based production welding and pipefitting in a depot-scale environment. More like a civilian shipyard workflow — eight-hour days, less operational pressure, more formalized training. Good for building technical depth; does not build the shipboard DC and watchstanding experience that matters for advancement boards.

What Good Looks Like at This Rank

The good HTFN is the apprentice the second class sends alone to the repair locker at 0600 to do the weekly inventory, and the count comes back correct, the discrepancies are already logged in CSMP before he returns to the shop, and the expired AFFF canister he found is tagged and written up rather than quietly put back on the shelf. He did not have to be told what to do with it — he read the SOP, the SOP said report discrepancies before closing the locker, and he did. By month eight, his basic welder qualification is signed. Not because the first class pushed him to book the test — because he booked the test himself after running five consecutive practice coupons that passed his own visual check. The coupon he submits to the Welding Inspector passes on the first attempt. The Inspector's comment is 'consistent travel speed.' The HTFN logged five hours of practice in the shop before that test. Nobody asked him to. His DC PQS is 80% complete. The remaining line items are the practical demonstrations that require a qualified evaluator — he has already scheduled two of the three with the HT2 who runs the PQS board. The LCPO does not have to ask where the PQS stands because the HTFN updates the tracking board himself on Fridays. The senior HT in the division has already started calling him by his last name instead of 'the new guy,' which in R-Division means something.

Preview — The Next Rank

HT3 is when the crow goes on and the watchbill actually means something. You are now a petty officer, and petty officer means you own a section of the 3-M schedule, you sign your name to HTFN PQS line items, and the first class is watching whether you can execute the complex pipe job without supervision or whether you need the hand-holding that was appropriate at the HTFN level but is not acceptable at the HT3 level. The weld progression accelerates at HT3 — 2G, 3G, 4G, overhead. The 1G was the entry credential; the full position battery is the working credential. And the NEC conversation goes from planning to action — the HT3 who does not have a NEC packet moving is the HT3 who watches the HT2 advancement cycle from the bench.
