Recruiter vs. Reality
What they tell you

You'll be the Navy's shipboard firefighter, flood control specialist, and nuclear-biological-chemical defense expert — the rate that stands between a ship's crew and catastrophic loss when a fire, flooding, or NBC event threatens the vessel. The training at Center for Security Forces and subsequent shipboard qualification is the most intensive shipboard emergency response training in any branch. Municipal fire departments and industrial fire brigades actively recruit Navy DCs because the shipboard fire suppression and damage control experience is technically superior to most civilian fire academy programs. HAZMAT technician and hazardous materials response careers are also direct pathways from DC background.

What it's actually like

Your job is to prevent the ship from sinking, flooding, or burning, which would be stressful enough if you didn't also have to maintain every piece of equipment related to those three outcomes simultaneously. Portable submersible pumps. AFFF systems (aqueous film-forming foam, the fire suppression agent that is simultaneously effective and an environmental catastrophe). OBA — oxygen breathing apparatus, the rebreather you will don in a smoke-filled space while everyone else is running the other direction. DC central is your kingdom: the compartment where all the damage control monitoring systems feed in and where the DC Petty Officer watches the ship's survivability status in real time. General quarters drills, INSURV inspections, and CART/TSTA workups will become the rhythm of your life. The firefighting skills are real and translatable — civilian ARFF (aircraft rescue firefighting) and industrial firefighting both have pipelines that respect your background. HVAC and piping knowledge is substantial. What nobody tells you is that DC carries a specific kind of weight: you are the rate that gets called when the ship is actually in danger, and the difference between a controlled emergency and a catastrophe is whether you and your team were ready. You will always be ready. That is not a small thing.

Duty StationsNorfolk (VA) · San Diego (CA) · Pearl Harbor (HI) · Yokosuka (Japan) · Various surface ships (DDGs, CGs, CVNs, LHDs)
Daily LifeOn a ship: managing the damage control program, maintaining firefighting equipment, conducting DC drills, welding, pipe-fitting, and maintaining CBR (chemical, biological, radiological) defense systems. DCs are the ship's emergency response team — when something goes wrong, you run toward it. Shore duty includes fire stations, repair facilities, and training commands.
AIT / SchoolA School at Great Lakes (IL) is about 9 weeks. Covers firefighting, flooding control, shoring, welding, pipe-fitting, and CBR defense. The training is intensely hands-on — you will fight real fires and deal with simulated flooding. If you're claustrophobic, this is not your rate.
Physical DemandsHigh. Firefighting in full gear, shoring up damaged bulkheads, operating damage control equipment under stress, and hauling heavy gear through tight spaces. This is physically demanding and requires comfort in enclosed spaces.

Pro Tips
  1. 1Your welding and pipe-fitting skills are directly transferable to civilian industrial jobs paying $60-100K+. Get as many welding certifications as the Navy will give you.
  2. 2DC is one of the most respected rates on any ship because everyone depends on you when things go wrong. That respect translates into strong evaluations if you perform.
  3. 3Document your HAZMAT and fire certifications through USMAP. Civilian fire departments and industrial facilities value these credentials.
The Honest Truth

Damage Controlman is one of the most underrated rates in the Navy. The recruiter probably won't lead with DC because it's not glamorous — but it's essential. You are the reason ships don't sink and sailors don't burn. The training is real: you fight actual fires, you plug actual floods, and you weld actual steel. The physical demands are high and the work conditions can be miserable (hot, dirty, confined spaces). But the skills you learn — welding, pipe-fitting, HAZMAT, firefighting — translate directly to well-paying civilian trades. Welders with DC experience routinely land $70-100K+ in shipyards, refineries, and industrial facilities. Promotion is steady because the rate is always needed. If you want a hands-on trade that's genuinely important, DC delivers.

E1-E3SR — DCSN (Apprentice DC)

You are the newest sailor in the Repair Locker. Every senior DC on the ship knows you do not know anything yet — your job is to prove them wrong faster than they expect.

What You Actually Do

Fresh out of DC "A" School at Center for Surface Combat Systems (CSCS), Dahlgren VA, you check aboard and get handed a Repair Locker inventory sheet and a stack of PQS sign-off sheets before you can find the berthing. Your first months are about learning the ship — every watertight fitting in your damage control zone, every DC equipment locker, every P-100 dewatering pump, every AFFF station, and the name of every chief who can end your advancement before it starts. You run Repair Locker drills, help with the PMS cycle on portable firefighting equipment, study NSTM Chapter 079 for the in-rate knowledge your LPO will test you on, and stand duty in whatever billet the watch bill assigns. You earn the DC Qualification by walking every zone until your LPO trusts that you know the ship as well as the shipyard that built it. Whether you end up on a surface combatant, an amphib, or working afloat firefighting at a shore command depends on orders — but your next command will judge you by what your current command wrote in the eEVAL.

Key Skills to Drill
  • 01Walk your assigned DC zone and identify every watertight fitting, boundary, and damage control equipment locker to your LPO's standard without a diagram.
  • 02Don, seal, and operate an OBA (Oxygen Breathing Apparatus) or SCBA in under two minutes — every time, not just in drill.
  • 03Set up and operate a P-100 portable dewatering pump from a cold start, including suction hose rigging and discharge routing, to NSTM Chapter 079 procedures.
  • 04Apply emergency shoring — standard and portable — to a hull breach model as the plug-and-patch team member, not just the observer in the passageway.
  • 05Identify and fight a Class A, B, C, and D fire with the correct agent, approach, and egress plan — Aqueous Film-Forming Foam (AFFF), CO2, PKP, and the difference between application techniques.
  • 06Know the ship's stability and buoyancy basics: list vs. trim, flooding effect on righting moment, and when to call DC Central instead of plug it yourself.
Manuals & References
  • NSTM Chapter 079 — Damage Control (the DC bible; the chiefs will quiz you on chapters you cannot identify by number yet — read ahead).
  • NSTM Chapter 555 — Firefighting (the firefighting employment manual; every technique you demonstrate on a drill traces back to this chapter).
  • NSTM Chapter 074 — Gas-Free Engineering (required before any hot work or enclosed-space entry in your DC spaces).
  • OPNAVINST 3400 series — Nuclear, Biological, and Chemical (NBC) Defense; you will be the CBR locker runner until you qualify the equipment.
  • Damage Controlman NAVEDTRA Rate Training Manual — start the advancement bibliography now; the NWAE for DCFN → DC3 is closer than it looks.
  • OPNAVINST 6110.1 — Navy Physical Readiness Program (your PRT/BCA standard; firefighting gear weighs more when your cardio is bad).
Standards You Must Hit
  • DC Watch Qualification signed off on the LCPO's timeline — the seaman who cannot pass the ship's DC watch qual board is invisible at the next NWAE cycle.
  • OBA / SCBA proficiency signed off and current; respiratory protection medical clearance in place before your first actual entry.
  • All PMS checks assigned in the 3-M system completed on time and documented — the DCPO will not defend a missed PMS period during the next INSURV inspection.
  • PRT Good Low or higher; BCA in standard. Dragging during a firefighting drill in full bunker gear is not the introduction you want to the chief.
  • NWAE study habit established — pull the current Bibliography for Advancement Exam Study (BIB) and own it; the DC3 selection window is faster than most apprentices plan for.
Common Technical Mistakes
  • Opening a boundary before checking for fire or flooding on the other side. You make the casualty worse, you kill the sailor behind you, and the CO hears your name in the AAR.
  • Skipping OBA / SCBA cylinder pre-checks because "the last watch just used it." The cylinder that runs out at minute six of a Class Bravo fire is your cylinder, and that problem is permanent.
  • Securing a dewatering pump and leaving suction hose deployed in the space. The next person in the space trips, the pump was never properly stowed, and the 3-M PMS record shows your initials.
  • Free-communicating stability concerns to the crew without routing through DC Central first. Rumors about flooding or list cause more casualties than some floods — the DC chain exists for exactly this reason.
  • Treating a drill as a performance. If the OBA takes 45 seconds to don in drill because you are nervous about looking slow, it will take 90 seconds when the space is on fire. The LPO notices — and so does the smoke.
What Good Looks Like

The good DCSN is the sailor the LPO sends to show the new check-in around the Repair Locker, because the PMS is in order, the zone walk is clean from memory, and the OBA don time is already under a minute and a half. By month nine the DC Watch Qual is complete, the NWAE bibliography is annotated, and the DCPO is asking whether the next NEC pipeline conversation should happen before or after the DC3 board.

E4DC3 (Petty Officer Third Class)

You are a petty officer now. The crow means you own a piece of the watch bill, a portion of the PMS cycle, and at least one DCSN who is watching whether the standard is real or a paperwork drill.

What You Actually Do

You own a section of the Repair Locker equipment accountability, a watch station in DC Central or as Repair Party Leader on smaller platforms, and you execute the DCPO's PMS schedule instead of just attending the working party. You run new-arrival zone walks, train DCSNs on OBA / SCBA donning and dewatering pump operation, and you are the one who knows where every piece of Repair Locker equipment actually is when the XO calls away a GQ drill at 0300. The "C" school conversation gets serious: NEC 1425 (DC Advanced Firefighting), NEC 2805 (NBC Defense), or the instructional pipeline at CSCS if you want to teach. Pull the current NAVADMIN for advancement quotas and NEC source-rating messages before you build a plan around what your buddy told you last year. The DC2 board is not abstract — your eEVAL profile and your PMS completion rate are already being read.

Key Skills to Drill
  • 01Lead a Repair Locker muster and equipment accountability check before a drill — every OBA, every hose, every submersible pump accounted for and operational before the alarm sounds.
  • 02Operate DC Central as a qualified watch stander — track flooding reports, fire boundaries, and ship stability data simultaneously; know when to route to the DCA and when to act inside standing orders.
  • 03Conduct an OBA / SCBA two-person team firefighting entry on a Class Bravo fire model — approach angle, fog pattern, team communication, and egress without losing each other in zero visibility.
  • 04Perform and document emergency shoring on a simulated hull breach — wood shores, portable shores, and wedge installation — to NSTM Chapter 079 standards with a DCSN working under your direction.
  • 05Administer CBR decontamination procedures for personnel and equipment as a qualified NBCD station operator, per OPNAVINST 3400 series.
  • 06Read and interpret a Damage Control Book (DC Book) diagram to identify routing, system isolation, and flooding boundaries for a section of the ship not in your primary zone.
Manuals & References
  • NSTM Chapter 079 — Damage Control (own the chapters on dewatering, shoring, stability, and Repair Party organization cold).
  • NSTM Chapter 555 — Firefighting (the employment manual for every agent and technique you demonstrate on the fireground).
  • NSTM Chapter 074 — Gas-Free Engineering (pre-entry testing, hot-work permits, and the procedures that keep sailors alive in enclosed spaces).
  • OPNAVINST 3400 series — NBCD Defense (your CBR qualification package traces to this series).
  • Damage Controlman NWAE Bibliography (BIB) — current cycle; pull from MyNavyHR / NETC, not from a shipmate's stale folder. The BIB is the test.
  • NAVPERS 18068 Vol II — the NEC catalog; read the entries for NEC 1425 (Advanced Firefighting), NEC 2805 (NBC Defense), and instructor NECs before you talk to the career counselor.
Standards You Must Hit
  • NWAE for DC2 prep on the LCPO's timeline — the petty officer who walks into the advancement exam without a study log is the one who watches the slate from the bench.
  • PRT Good Medium or better; BCA in standard. Dragging a charged 2.5-inch hose in full bunker gear to the second deck during a drill is a conditioning test as much as a skills test.
  • All PMS divisions within your accountability current and verified in the 3-M system — INSURV and the DCPO will not distinguish between your personal PMS record and the Locker's record.
  • At least one NEC pipeline packet in motion (NEC 1425, NEC 2805, or instructional NEC) — or a documented reason you are still building the next one.
  • eEVAL trait average that supports an EP if the command wants to push you — your LPO knows the number weeks before the EVAL drops, and your PMS record is the evidence file.
Common Technical Mistakes
  • Reporting a dewatering pump as fully operational on the PMS sheet without running it. The pump that fails on the first stroke during a flooding casualty has your initials on the last PMS check.
  • Conducting an enclosed-space entry without an atmospheric test and a designated safety observer. One missing step and a sailor does not come out — and the inquiry starts with "who was the DC watch?"
  • Using the wrong extinguishing agent on a Class Bravo fire because the nearest extinguisher was PKP and it was closer. Class B fires re-flash; the wrong agent costs lives and the investigation costs your career.
  • Letting a DCSN skip OBA pre-checks because the drill is "just practice." The training repetitions are the only reason the real-world execution is survivable — drill standards are operational standards.
  • Posting unit or underway information on social media with geolocation or INSURV-relevant content visible in the background. The OPSEC officer runs sweeps, and your chief hears about it before you do.
What Good Looks Like

The good DC3 is the petty officer the LPO trusts to run the Repair Locker muster and equipment check before a GQ drill when the DCPO is on the bridge. His PMS record is clean, his DCSNs can don OBAs in under two minutes, and when the XO walks through the Repair Locker space after drill, there is nothing on deck that does not have an owner. He is on the NEC slate conversation before his first EP eEVAL closes.

E5DC2 (Petty Officer Second Class)

You are the working senior DC. The DC3s call you LPO whether the title is on the watchbill or not, and the chief is pushing you toward the anchors he expects to pin in two or three boards.

What You Actually Do

You run a Repair Party section or own a damage control zone as the senior petty officer responsible for PMS completion, equipment readiness, and the qualification track for the DC3s and DCSNs under you. On larger combatants you may stand as Repair Locker Leader (Repair 2, 3, or 5) during GQ — that means you are the senior enlisted voice in that space during a real casualty, making flooding and firefighting decisions with DC Central on the circuit and the DCA watching your reports. NEC-coded billets define what comes next: NEC 1425 (DC Advanced Firefighting) opens instructional billets and senior afloat positions; NEC 2805 (NBC Defense) makes you the NBCD technical authority in your command. The NWAE for DC1 is no longer abstract — the eEVAL ranking against your peer DC2s actually matters for the next slate, and the chief who writes your EVAL is already comparing your PMS completion rate to the fleet average.

Key Skills to Drill
  • 01Lead a Repair Locker as the senior enlisted voice during GQ — report flooding and firefighting status to DC Central, direct boundary setting, coordinate dewatering, and manage OBA team rotations without DC Central having to ask twice.
  • 02Conduct P-100 and P-250 dewatering pump operations simultaneously during a multi-space flooding drill — pump sequencing, suction management, discharge routing, and stability implications briefed up the circuit as conditions change.
  • 03Run AFFF system employment and deck foam application on a Class Bravo flight-deck or hangar-bay scenario — deployment sequence, agent coverage, knockdown assessment, and reflash prevention.
  • 04Execute a Halon or clean-agent substitute suppression-system activation sequence for an engineering space fire — isolation steps, ventilation shutdown, boundary setting, and re-entry criteria per NSTM Chapter 555.
  • 05Build and sign off PQS / 301-series qual line items for DC3s and DCSNs as the authorized signer — your signature is the standard, and your LCPO reviews what you put your name on.
  • 06Write the DC section of a ship's force damage control training schedule — frequency, equipment to be used, personnel in each drill billet, and the written exam that validates the knowledge component.
Manuals & References
  • NSTM Chapter 079 — Damage Control (fluent in the stability and buoyancy, Repair Party organization, and dewatering chapters you sign training against).
  • NSTM Chapter 555 — Firefighting (the employment manual you teach from — agent selection, approach, foam application, re-entry criteria).
  • NSTM Chapter 074 — Gas-Free Engineering (you sign enclosed-space entry permits; one error here ends careers and lives simultaneously).
  • OPNAVINST 3400 series — NBCD Defense (you build the CBR training plan; every qualification in the locker traces back to this series).
  • DCA instruction cycle and ship's Damage Control Bill — know the bill cold; the DCA will expect you to execute it without re-reading it during a real casualty.
  • NWAE Bibliography for Advancement (BIB) for DC1 cycle — pull the current version from MyNavyHR / NETC; build a study plan with milestones, not a stack of unread PDFs.
Standards You Must Hit
  • NWAE for DC1 prep documented on the LCPO's timeline; the candidate who walks in with a clean EAW and a defensible BIB study log is the candidate the chief fights for at the quota board.
  • NEC 1425 or NEC 2805 awarded or in-pipeline — the DC2 without an NEC pathway is visible for the wrong reason at the next ranking board.
  • PRT Good High or better; BCA in standard. Gear-intensive, physically demanding work — the Repair Locker performance standard is set at GQ conditions, not at the quarterdeck.
  • Repair Locker equipment readiness at or above command average — every OBA, every pump, every hose and nozzle, verified and on the 3-M record before the LPO asks.
  • eEVAL trait average and ranking that supports EP/MP recommendation; your LCPO knows your number before the EVAL board reads it, and your PMS completion percentage is the number everyone checks first.
Common Technical Mistakes
  • Letting a DC3 certify a Repair Locker equipment check without physically verifying critical items — the OBA with the dead cylinder and the shoring kit with the missing wedges both have your quality-control signature on them.
  • Failing to report a pump failure or equipment discrepancy to DC Central immediately because "we have the backup." DC Central models the ship's casualty response on what you report; wrong inputs produce wrong decisions at the worst possible time.
  • Treating the enclosed-space entry permit as a form and not a procedure. The fatalities from skipped atmospheric checks did not happen in drills — they happened when the team was certain the space was safe.
  • Practicing past your NEC scope under pressure and not documenting after. Your NEC scope (especially NEC 1425 advanced firefighting and NEC 2805 NBC) is broader than a non-coded DC2 — but it is bounded, and what you did in a real casualty has to survive a JAG inquiry.
  • Going around the LCPO to the DCA during a discrepancy dispute. The DC chain runs through your chief; the goat locker hears about it the same watch, and your DC1 packet feels it six months later.
What Good Looks Like

The good DC2 is the petty officer the DCA sends to represent the ship's damage control program when SUBLANT or SURFLANT sends a readiness inspector and the DCPO is in the wardroom. His Repair Locker numbers are clean, his DC3 has a NEC packet on the table, and his eEVAL bullets are action-result-impact — not generic DC filler that sounds the same as every other petty officer in the rate.

E6DC1 (Petty Officer First Class)

You are the LPO. The chief is editing your Chief packet. The DCA calls you by name. The DC2s and DC3s watch how you carry the division the way you used to watch the chief.

What You Actually Do

You are LPO of a damage control division — running 10-20 DCs, owning the command's Repair Locker readiness across multiple zones, managing the 3-M PMS program for DC equipment, and defending the ship's damage control training schedule at the DCA's department head sync. You write four-to-six eEVALs per cycle for DC2s and DC3s that pick the next NWAE slate and determine who makes the NEC pipeline. You build the ship's force DC training calendar, mentor at least one sailor a year into an NEC pipeline or commissioning program (Seaman to Admiral, LDO / CWO, MECP), and you run GQ drills that the INSURV team cannot break because the muscle memory was built correctly before they showed up. The Chief board packet conversation is no longer abstract — your LCPO is editing your record, your eEVAL profile is being built across the year, and the warfare device on your blouse is the first thing the Chief board reads before they open the narrative.

Key Skills to Drill
  • 01Run a Repair Party exercise at the division level — from GQ station bill assignment through debrief — with realistic injects, accurate equipment sequencing, and an AAR the DCA can brief to the XO without rewriting.
  • 02Manage the 3-M PMS program for DC equipment across your entire zone — ship-wide OBA, SCBA, portable firefighting equipment, dewatering pumps, shoring kits, AFFF systems — with a completion and discrepancy rate the DCPO can defend at INSURV.
  • 03Defend a DC readiness brief to the DCA and department head — equipment status, training completion, PQS completion rates, known discrepancies with mitigation — without the wardroom rewriting your numbers.
  • 04Build and execute a ship's force damage control training calendar aligned to the DCA's instruction cycle, the command's operational schedule, and the TYCOM training requirements.
  • 05Mentor a DC2's NWAE / NEC / commissioning packet from idea to selection — and counsel honestly when the pipeline is wrong for the sailor's goals or timeline.
  • 06Write an eEVAL block the senior rater can defend at a wardroom board — measurable accomplishments, named outcomes, the language the Chief board actually reads, not the placeholder bullets that describe every DC LPO in the fleet.
Manuals & References
  • NSTM Chapter 079 — Damage Control (fluent across all chapters; you are the LPO the DC2s come to with the specific procedure question, not the one who has to look it up).
  • NSTM Chapter 555 — Firefighting (the full manual; you teach from it and you defend the command's training program against it at every inspection).
  • NSTM Chapter 074 — Gas-Free Engineering (you sign the permits and you build the training; one procedural shortcut here creates the fatality that ends the division).
  • OPNAVINST 3400 series — NBCD Defense (you own the NBCD training program; the DCPO expects your qualification rates to brief without an asterisk).
  • NAVPERS 18068 Vol II + the current NEC source-rating NAVADMIN — you build the NEC pipeline off the current cycle, not the version on the shared drive from two deployments ago.
  • DCA instruction cycle, ship's Damage Control Bill, and TYCOM DC training requirements — the full stack you plan the training schedule from; the INSURV team reads all three before they walk aboard.
Standards You Must Hit
  • Chief board packet under construction with the LCPO's eye on every line; eEVAL profile defensible at wardroom / command level; warfare device pinned and current.
  • Ship's DC readiness — PMS completion rate, PQS completion rate, NEC-coded billets filled, NBCD qualification rate — defensible at DCA and department head level every cycle, no caveats.
  • INSURV / TYCOM readiness inspection DC discrepancy rate at or below command benchmark; no LPO-attributable CAT-I findings during your tenure.
  • Pipeline output — NEC 1425, NEC 2805, LDO / CWO, commissioning, or NWAE advancement — producing at least one selectee per year from your division.
  • NWAE for Chief is replaced by the Chief Petty Officer selection board; the package is built across the year, not the week before submission. The LCPO defines the cadence — follow it.
Common Technical Mistakes
  • Briefing DC readiness numbers you have not personally validated. The DCA catches the gap at INSURV and your Chief packet absorbs it permanently.
  • Letting a senior DC2 carry the enclosed-space entry permit accountability because "he is your guy." When he transfers the gap surfaces and the LPO's name is on the JAG inquiry and the fatality report.
  • Confusing seniority with technical authority. The DCA and the Safety Officer own the risk-acceptance calls on hot work and enclosed-space entry; you own the enlisted execution, training, and documentation that defends the procedure after the fact.
  • Going around the LCPO to the DCA or XO. The chiefs talk; the next Chief board sees the pattern, and "went around the chain" is not a trait that reads well in a recommendation letter.
  • Treating the Seaman-to-Admiral / LDO / CWO mentoring conversation as a checkbox. The sailors you put through commissioning at this rank contribute to the officer and warrant corps NAVSEA depends on for the next generation of damage control professionals.
What Good Looks Like

The good DC1 is the LPO the LCPO trusts to run the division for a week underway without daily check-ins, including during a real GQ event. His readiness numbers brief without caveat, his eEVALs select DCs above the fleet average, and his INSURV prep produces inspection scores the DCA names in the command's awards submission. He sits the Chief selection board with a record that reads itself.

E7DCCS (Chief Petty Officer)

You are a Chief. The gold-fouled anchors mean the goat locker is yours, the wardroom asks you by name, and the entire division reads the command's damage control posture off how you stand at GQ.

What You Actually Do

The job changes more between DC1 and DCCS than at any other promotion in the rate. As LCPO of the ship's damage control program — leading 15-40 DCs across all Repair Parties, owning the 3-M PMS program for the entire DC equipment inventory, and standing as the senior enlisted DC voice in DC Central during GQ — you own the deckplate execution that keeps the ship afloat when something goes wrong. You write Chief-quality eEVALs that pick the next DC1 and DCCS slate; you sit at DCA department head sync as the senior enlisted voice; you walk the Repair Lockers during a real-world GQ event, flooding drill, or INSURV readiness inspection and identify the broken systems before the inspector does. You build the next LPO. You mentor the next NEC pipeline and commissioning candidate. You enforce the standard, in uniform, every day, while the deckplate watches whether your liberty habits match your GQ posture. At this rank you also start the harder conversation with the DCA about the ship's damage control culture — whether the drills are building real capability or just generating satisfactory inspection marks.

Key Skills to Drill
  • 01Run an LCPO's mess of DCs — accountability, training, readiness, PMS compliance, discipline, family readiness, finance — with weekly cadence the DCA and department head can predict without asking.
  • 02Defend the ship's DC readiness posture at command-level sync — 3-M PMS completion, PQS rates, NEC-coded billets, NBCD qualification rates, INSURV-open discrepancies — without the DCA rewriting your numbers.
  • 03Walk a real-world GQ event or INSURV / TYCOM readiness inspection as the senior enlisted DC voice on scene — your AAR is what the wardroom briefs up the chain to SURFLANT or SUBLANT.
  • 04Mentor four-to-six DC1s into Chief-board-competitive candidates; mentor at least one NEC 1425 / 2805, LDO / CWO, or commissioning packet to selection per year.
  • 05Operate as the senior enlisted damage control voice during a deployment or contingency — including the call to wake the CO at 0200 when the DC posture has actually shifted and the flooding report changes the stability picture.
  • 06Translate NAVSEA / TYCOM damage control policy and INSURV lesson-learned circulars into deckplate decisions the DCs rehearse without rewording the directive.
Manuals & References
  • NSTM Chapter 079 — Damage Control (full library; you are the LCPO the DCA's junior officers come to with the technical question the manual did not clearly answer).
  • NSTM Chapter 555 — Firefighting; NSTM Chapter 074 — Gas-Free Engineering (full familiarity across both; you are the senior technical authority for ship's force on both).
  • OPNAVINST 3400 series — NBCD Defense (you defend command NBCD qualification rates; the inspection team compares your numbers to the TYCOM average).
  • MILPERSMAN — fluent in the articles that govern enlisted personnel actions (advancement, retention, separation, NJP) at DCCS-level visibility.
  • CPO 365 / CPO Initiation guidance — the wardroom and the goat locker hold you to it, even after the anchors are pinned and the drills are real.
  • INSURV and TYCOM readiness inspection lesson-learned messages — pull them as they are released; the inspector who walks aboard your ship read the same ones, and the command that ignores them is the one that gets the CAT-I finding.
Standards You Must Hit
  • CPO Academy / Chief's Mess transition complete; standing as a Chief in the mess at the deckplate level — not a Chief in title alone who defers every DC decision to the LPO.
  • Ship's DC readiness — 3-M PMS, PQS, NBCD qualification rates, INSURV-open discrepancy aging — defensible at DCA, department head, and command level, every cycle.
  • eEVAL profile and ranking that picks the next DC1 and DCCS slate from your division — measured by which sailors actually select, not by how well you write a recommendation letter.
  • Pipeline producing 1+ NEC 1425, NEC 2805, LDO / CWO, or commissioning selectee per year, with the wardroom able to name them at the next command awards board.
  • Zero Chief-level integrity incidents — fraternization, financial, OPSEC, safety permit falsification. One ends the career permanently and there is no recovery in a rate where the ship's survival depends on signed documentation being accurate.
Common Technical Mistakes
  • Mistaking the goat locker for a private club. The mess is a working leadership platform; the DCCS who treats it as social is the one the DCA stops inviting to the pre-INSURV brief.
  • Stopping personal PT and DC equipment proficiency because "I am a Chief now." The deckplate reads the DCCS who cannot make a Repair Locker evolution harder than they read the DC3 who cannot — and the DCA reads the same thing.
  • Letting a DC1 LPO run a bad Repair Party because he is "your guy" or "almost a Chief." The DCA and the CMC see the INSURV finding first, and the Chief board sees the LPO's slate before you explain it.
  • Going public with disagreement with the DCA, XO, or CO. The disagreement happens in the office; you walk out aligned. The goat locker enforces this without the wardroom having to ask.
  • Treating the NEC / LDO / commissioning mentoring conversation as a checkbox. The DC officers and warrant officers you build at this rank shape NAVSEA's afloat damage control bench for the next decade — counsel honestly about ADSO, OCS, and the career they actually want, not the one that looks good in the recommendation.
What Good Looks Like

The good Chief Damage Controlman is the LCPO the CO names to the INSURV team as the reason the ship's DC program passed without CAT-I findings. His DC1s pick up Chief, his NEC and commissioning packets select at rates above the type-command average, and his deckplate posture during a real-world flooding event matches his posture during every drill that led up to it. He is on the Senior Chief slate before the CMC has to recommend it.

E8-E9DCCM — DCCCS (Senior/Master Chief)

You are the senior enlisted damage control voice in a command, staff, or training establishment. The CO names you in the readiness brief. NAVSEA and TYCOM know your name from inspection reports. The deckplate watches whether you still walk the Repair Locker.

What You Actually Do

As DCCM or DCCCS you run the senior enlisted damage control posture for a large-deck combatant, an amphibious ready group, a TYCOM afloat staff, a NAVSEA / NSWCDD training command, or a major shore command. You write fewer eEVALs but they are the ones that pick the next Chief and Senior Chief slate. You sit at command-team sync as the senior enlisted voice on every enlisted DC decision — accession, training, retention, NEC credentialing, INSURV preparation, discipline. You translate NAVSEA / CNO / TYCOM damage control policy into command-level talent management decisions and deckplate training programs. You build the next CMC / COB / SEA selectee among the DC Chiefs. You start the post-Navy market plan 24-36 months out — NAVSEA civilian GS-11/12/13 track, federal fire protection and industrial safety (DoD fire departments, OSHA federal agencies), defense contractor technical training, or shipyard damage control positions — because the bench you leave behind is what decides whether the goat locker and NAVSEA both remember your name.

Key Skills to Drill
  • 01Run a senior-enlisted command climate across a DC program or command that produces NEC-credentialed petty officers, INSURV-ready Repair Parties, and commissioning accessions at rates above the type-command average.
  • 02Brief the CO, DCA, TYCOM, or NAVSEA inspector on enlisted DC readiness and risk in language the flag officer can defend at the next echelon — without rewriting and without minimizing a real capability gap.
  • 03Sit on Chief selection board panels, command CMC slates, LDO / CWO accession boards, and senior-enlisted training cadre selection panels with the discipline and confidentiality the convening authority requires.
  • 04Translate NAVSEA / CNO / OPNAV damage control policy, INSURV lesson-learned messages, and DC technical manual revisions into enlisted talent management decisions at the unit and across the rate.
  • 05Run a real-world damage control evolution, shipboard casualty response, or INSURV readiness inspection as the senior enlisted DC voice — and your AAR and lessons-learned become the curriculum the next command uses.
  • 06Run a Red Cross / casualty notification or memorial service with the dignity it requires. At this rank you have been through enough of them that the standard is personal, not procedural.
Manuals & References
  • NSTM Chapter 079, 555, and 074 — full library; you are quoted from these more than you quote them, and when an INSURV finding cites a procedure gap you are expected to have caught it first.
  • OPNAVINST 3400 series — NBCD Defense (you are the rate's NBCD authority at the command level; the inspection team compares your program to the TYCOM standard).
  • MILPERSMAN — fluent on enlisted personnel actions at the senior-enlisted threshold; you are in the room for NJP, separation, and high-visibility safety-related investigations.
  • OPNAVINST 1306.2 series — detailing and assignment policy as it applies to senior-rate DCs; you advise the command on billets and pipelines the career counselor has not seen before.
  • Senior Enlisted Academy (SEA, Naval War College Newport RI) reading list and CPO / CMC Symposium materials — you consume doctrine and translate it down to DC3s who have never seen an INSURV.
  • NAVSEA, TYCOM, and CNO damage control policy memos, INSURV lesson-learned messages, and NAVADMINs — current; pull each one as it drops, not from a stale shared-drive folder.
Standards You Must Hit
  • SEA fellowship or equivalent senior-enlisted PME complete before competing for command CMC / COB slate.
  • Command-level damage control inspection (INSURV, TYCOM readiness assessment, CNSP / CNSL afloat readiness review) passed without senior-enlisted-attributable findings during your tenure.
  • NEC 1425, NEC 2805, LDO / CWO, and commissioning accession pipeline producing 1+ selectee per year from your command — and the wardroom can name them.
  • eEVAL profile that the senior rater can defend at command and TYCOM level — your rated chiefs are picking up Senior Chief and Master Chief on the timeline the command expects.
  • Zero senior-enlisted-level integrity incidents — financial, fraternization, safety permit falsification, OPSEC. One ends the career permanently and there is no recovery at this paygrade; the investigation also names every inspection you signed for.
Common Technical Mistakes
  • Pretending to current technical authority on a DC system or procedure where you are out of date. Senior DCs lose authority by faking depth — the DCA, the INSURV team, and the DC1s all see it inside the same brief.
  • Letting a Chief-led Repair Party drift on PMS completion or qualification rates because "the wardroom will catch it at INSURV." You own the enlisted execution at the command roll-up; the inspector finds it under your name, not the DCA's.
  • Treating the NEC / LDO / commissioning mentoring conversation as transactional. The DC officers and warrant officers you support at DCCM level build the technical DC bench NAVSEA depends on for the next generation of afloat programs.
  • Going public with disagreement with the CO, DCA, or TYCOM. Take it in the office with the door closed. Walk out aligned. The goat locker and the wardroom both enforce it, and at this rank the disagreement that leaked is the one that ends the career.
  • Confusing the warm-up to retirement with the job. Until you walk out of the formation for the last time, the ship's damage control posture is your job — and the deckplate reads which one you are working every time GQ sounds.
What Good Looks Like

The good Master Chief Damage Controlman is the senior enlisted DC voice the CO, DCA, TYCOM, and NAVSEA inspector all name without thinking. His command's DC readiness slate is the one SURFLANT quotes in lessons-learned guidance; his NEC and commissioning accession rate is in the upper third of the rate; his rated chiefs pin Senior Chief and Master Chief on the timeline the command expects. When he retires, NAVSEA civilian hiring and DoD fire protection leadership already have his name, and the goat locker remembers the inspection records he left behind — not the position he held.

Reviews
Founding ReviewUnclaimed

Nobody’s gone first. Yet.

Zero reviews for DC. Not because nobody has opinions — anyone who’s actually done Damage Controlman 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 DC 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.

FAQ

DC Damage Controlman — FAQ

Q01What does a DC do in the Navy?
Fresh out of DC "A" School at Center for Surface Combat Systems (CSCS), Dahlgren VA, you check aboard and get handed a Repair Locker inventory sheet and a stack of PQS sign-off sheets before you can find the berthing.
Q02How long is DC training and where is it held?
DC training is approximately 10 weeks of Advanced Individual Training (AIT) after Basic Combat Training, held at Great Lakes, IL.
Q03What security clearance does a DC need?

Q04What does a day in the life of a DC look like?
A typical junior-enlisted DC day: 0500-0545 Wake, hygiene. If you are on duty section, check overnight DC watch turnover notes and any written discrepancies from overnight equipment checks before morning quarters, 0545-0630 Command PT or division PT. DC division PT tends to be conditioning-heavy — runs, ladder carries, sometimes bunker-gear conditioning. Fall out is not an option you want the LPO to see, 0630-0730 Hygiene, chow, transition to utilities.…
Q05What are the most common career-ending mistakes for a DC?
Barracks or liberty behavior that results in NJP, a DUI, or a command-level conduct incident before the DC3 board. The chief board at DC3 is an administrative evaluation of your record — a conduct incident at DCFN or DCSN does not disappear, and the CO's recommendation reads the pattern, not the single event; PMS falsification — signing a maintenance check you did not actually perform. At any paygrade this is a career-ending integrity violation,…
Q06What civilian jobs does DC translate to?
DC maps most directly to civilian occupations including Firefighters, Installation, Maintenance, and Repair Workers, All Other. Translation quality varies by skill — see the Honest MOS Civilian Translation block for full O*NET matches and salary data.
Q07What's the career progression for a DC?
First 60-90 days: Repair Locker zone walk complete from memory; OBA / SCBA proficiency real and signed off; PMS routine established in the 3-M system; Month 3-6: DC Watch Qualification PQS progressing on LPO's timeline; qualified to stand a DC-related watch billet; basic firefighting and flooding drill participation as crew member, not observer; Month 6-12: DC Watch Qualification signed off and board passed; NWAE bibliography pulled and opened for DCFN / DC3 advancement cycle;…
Q08How often do DC soldiers deploy?
Deployment tempo for DC is high — expect deployments roughly every 18-36 months. Standard sea/shore rotation with 7-9 month deployments on surface ships
Q09What's the recruiter not telling me about DC?
Your job is to prevent the ship from sinking, flooding, or burning, which would be stressful enough if you didn't also have to maintain every piece of equipment related to those three outcomes simultaneously.
