HEADS UP

EM2 is the first rank where you are actively responsible for other people's technical development, not just your own. The EM3s in your work center qualify on your signature. When the LPO is at a meeting and the division officer walks into the work center, you are the answer. If your evaluation narrative doesn't say you developed subordinates, trained junior sailors, and improved the work center's capability — not just performed your own tasks well — the chief ranked someone above you who did.

The Honest MOS Read
You are EM2 — Petty Officer Second Class — and the rating's career is starting to take a shape that distinguishes the sailor who will make First Class from the one who will plateau here. The EM2 is the work center's journeyman: technically capable enough to execute corrective maintenance without supervision, knowledgeable enough to write CSMP entries the chief doesn't rewrite, and visible enough in the work center that the EMFNs and EM3s below you are watching how you work. The technical scope at EM2 expands past the individual maintenance task. You're now the person the LPO assigns to plan a multi-day maintenance evolution — a main switchboard maintenance period, a generator-overhaul availability block, a casualty power system test sequence that involves coordinating with the engineering officer of the watch, the damage control assistant, and the other divisional petty officers whose equipment is affected by the planned power interruption. Planning the evolution means writing the work package, sequencing the tag-outs, identifying the test equipment and the personnel, and briefing the LPO before you execute. The EM3 who did this well as a junior petty officer becomes the EM2 who plans it for other people. The nuclear track at EM2 reaches its first major watershed. EMN EM2s on CVNs and submarines who have progressed through the nuclear watchstander qualification pipeline are standing watches that carry real responsibility — engine room upper level, propulsion plant watch supervisor under instruction, eventually the more senior watches that require demonstrated mastery of casualty response. The nuclear propulsion community measures EMN EM2s by the rate of qualification progression and the quality of responses in propulsion plant drills. An EMN EM2 who is standing the right watches and performing well on drills is in a different career position than the one who is behind the qual timeline. The Chief selection — Making Chief — is not yet the dominant conversation for most EM2s, but the record-building that determines the outcome of that conversation starts here. The Chief selection board reads entire service records. The evaluation narrative from the EM2 years, the war-fighting qualification depth, the school attendance and completion record, and the visible evidence of subordinate development — all of it is visible to the board. The EM2 who performs technically and develops no one is a different record than the EM2 who performs technically, writes a junior sailor's ESWS qualification PQS, leads a divisional training evolution, and earns a 'must promote' block in the eval narrative. The chief who writes that narrative is the one who ranked the EM2 first in the cohort. Make it easy for him. The Navy-Wide Advancement Exam to EM1 tests knowledge across the full EM rating bibliography — more depth in system-level troubleshooting, motor/generator maintenance, and the regulatory framework (NSTM 300, OPNAVINST 4790, the Maintenance and Material Management system) than the EM3 exam did. The EM2 who passes the E-5 → E-6 exam with a competitive score has typically been building the study habit for two to three years, not starting fresh at the exam window.
Career Arc
  • 01EM2 work center responsibility — planning multi-day maintenance evolutions, managing CSMP open items across the section.
  • 02Nuclear watchstander qualification milestones (EMN) — engine room, propulsion plant watch supervisor under instruction, casualty response drills.
  • 03Subordinate development: signing EM3 and EMFN PQS lines, mentoring ESWS qualification, leading divisional training events.
  • 04eEVAL ranking competition in the EM2 cohort — the record that feeds the Chief selection board five to seven years out.
  • 05NWAE study for the EM1 (E-5 → E-6) exam cycle — bibliography-driven, multi-year habit.
  • 06School or advanced NEC opportunities — advanced power systems, nuclear supplements, C-school availability.
  • 07Chief's Mess interaction: the CPO who mentors EM2s at this command is watching for the candidates who develop people, not just fix equipment.
Common Screwups
  • ×Failing to develop subordinates — the EM2 who does all the technical work himself and signs no PQS lines for junior sailors is ranked below the one who does both; the evaluation narrative makes the difference visible.
  • ×Missing the nuclear watchstander qualification timeline on a CVN or submarine — the division officer's monthly qualification review names the behind-schedule EMN EM2s to the chief engineer.
  • ×Letting the NWAE study habit lapse after pinning EM2 — the EM1 exam cycle arrives at the two-year mark and the EM2 who hasn't been studying watches the slate from the bench.
  • ×NJP, DUI, financial misconduct, or a sustained pattern of marginal PRT scores — any of these shows up in the evaluation ranking input and changes the Chief's Mess narrative about who the command's EM2 candidates are.

A Day in the Life

  • 0500-0530Up. Underway: coming off watch or preparing for the 0800-1200 maintenance block depending on the watch rotation. In port: check the day's work package. If you're opening a tag-out this morning, you have already briefed the LPO yesterday — today you execute.
  • 0600-0700PT — command PT three mornings per week on the pier, or self-directed on the ship's gym. Good High target, not just good enough. Your eval narrative competes with the other EM2s in the cohort and the PRT score is a visible differentiator.
  • 0700-0800Hygiene, breakfast, work center muster. The LPO briefs the day; you brief your junior sailors on their assignments and review the tag-out log for any open tags you initiated. Any discrepancies or schedule changes go to the LPO before 0800.
  • 0800-1130Maintenance execution — your assigned corrective maintenance item or the planned availability evolution. Junior sailors working with you are signing their own PMS cards under your supervision; you verify their work and sign the supervisory block. Any discovery items (unexpected faults found during maintenance) go to the LPO immediately, not at end of day.
  • 1130-1230Chow. Brief the LPO between breakfast and noon formation if a CSMP item needs a decision — parts order, SIMA package, deferred maintenance call. The EM1 who hears about an issue at 1200 has time to make a phone call before 1300; the same EM1 who hears at 1600 doesn't.
  • 1230-1500Afternoon maintenance or PQS development sessions with junior sailors. Two 20-minute PQS sessions per week for each junior sailor in your section. NWAE study for the EM1 exam when maintenance allows.
  • 1500-1600CSMP entries, maintenance record updates, tag-out clearances if work is complete. Tomorrow's work package reviewed and ready to brief the LPO. The junior sailors' PMS completion rate for the week tallied and reported before release.
  • 1600-1630Work center secured, tool locker checked, tag-out log audited for the end of day. Released (most in-port days).
  • 1800-2100Personal time. NWAE study at home or in the barracks. The EM1 exam bibliography is a sustained effort — tonight's 45 minutes of study is part of a six-month runway, not a sprint.
  • Underway watch (0000-0400 rotation example)Electric Plant Watch or Engineering Watch Supervisor under instruction (EMN). The machinery space is yours for the watch. Normal watch: monitor generator parameters, respond to minor alarms per the standing order procedure, log every 30 minutes. Casualty watch: isolate, notify EOOW, implement the casualty procedure, restore in sequence. The watch you stand at 0200 is the one the chief engineer hears about at the 0800 department training.

Weekly Cadence

The EM2's week runs on two simultaneous calendars: the work center's maintenance schedule and the junior sailor development calendar. Monday morning the LPO assigns the week's corrective maintenance by name — the EM2's name appears on the longer-duration, higher-complexity items. By Monday afternoon the EM2 has briefed his assigned junior sailors on the week's PQS sessions and scheduled the Tuesday and Thursday slots. The work center has a rhythm and the EM2 is part of the mechanism that keeps it running. Tuesday through Thursday are the densest working days. Major maintenance evolutions that require EOOW coordination are scheduled for midweek when the duty cycle is predictable. PQS sessions happen in the 30-minute margins between maintenance blocks — the EM2 who says 'there's no time' for PQS sessions during maintenance weeks is the EM2 whose junior sailors fall behind the ESWS timeline. There is always 30 minutes between the maintenance closing and the evening meal formation; it is a choice, not a constraint. Friday is the plan-of-week-out and the maintenance record close for the week. Every open CSMP item gets a status update — parts on order, SIMA package submitted, work complete. The LPO's Friday afternoon walkthrough is the informal inspection of the week's work; the work center that is clean, logged, and tagged correctly on Friday afternoon is the work center the LPO says yes to when the EM2 asks for a professional development afternoon next week. Underway, the week has no Friday — the watch rotation and the maintenance schedule are the only calendar. The EM2 who finds the PQS sessions and the study hours in the underway schedule is the EM2 whose record reflects them.

Key Skills — How to Drill Each

  1. 01
    Plan and execute a multi-day maintenance availability for a major electrical component — generator overhaul, main switchboard maintenance, casualty power system test — including the work package, tag-out sequence, personnel assignments, and EOOW coordination.
    Start the plan five working days before the evolution. Identify every tag-out required, the sequence in which isolation steps must occur, the test equipment needed, and the personnel who need to be present for each step. Brief the LPO on the plan the day before execution; brief the EOOW the morning of. The EM2 who walks into a major electrical availability with a written work package and a briefed team executes cleanly. The one who wings it from memory manages the chaos that follows the second unexpected equipment response.
  2. 02
    Mentor an EMFN or EM3 through ESWS qualification — signing PQS lines, running knowledge checks, and providing honest assessment of readiness for the qualification board.
    Walk the PQS chapter with the junior sailor yourself before you sign a line — know the standard before you certify it. The EM2 who signs lines without checking understanding is certifying false qualifications and the junior sailor fails at the ESWS board with the EM2's signature on the preparation record. Two 20-minute sessions per week with your assigned junior sailor, chapter by chapter, is the standard that produces a sailor who passes the board on the first attempt.
  3. 03
    Read a generator electrical performance log and identify trends — voltage regulation, frequency stability, load sharing between paralleled generators — before a performance deviation becomes a casualty.
    The performance log is only useful if someone reads it. Pull the last 30 days of generator log entries for your assigned generators once a week. Voltage regulation drifting high, frequency hunting under load, abnormal load-sharing between paralleled machines — any trend outside the normal band gets a note to the EM1 and an entry in the CSMP. The EM2 who caught the trend early and logged it is the EM2 the chief engineer praises at the next department training. The one who missed the trend is in a different conversation.
  4. 04
    Execute a ground detection sweep on the ship's electrical distribution system — identify a ground fault using the ship's ground detection system, isolate it to the branch circuit, and document the fault location for repair.
    Ground faults on a ship's 450V distribution are serious — a ground on one phase lowers the line-to-ground voltage on that phase and elevates it on the others, stressing insulation system-wide. The ground detection lamp/meter on the main switchboard shows which phase is grounded. From there, the isolation process involves systematically de-energizing branch circuits and watching the ground indication clear — when it clears, the last circuit de-energized contains the fault. Document the isolation sequence, report to the EOOW, and repair or tag out the faulted branch.
  5. 05
    Write a divisional training lesson plan and execute a 30-minute technical training session for EMFNs and EM3s — objectives, procedures, knowledge checks.
    The training lesson is the EM2's visible leadership product. State the objective at the top (what the junior sailor can do after the training that they couldn't do before), walk the procedure with the reference document open (not from memory alone), check for understanding with a scenario question, and close with the three things to remember. The LPO who walks in during the training sees the EM2 teaching, not just telling. The junior sailors who pass the ESWS board question the EM2 ran in the training session are the ones who remember his name at their advancement ceremony.

Manuals & References — What Chapters Matter

  • NSTM Chapter 300 — Electric Plant — General
    At EM2, you're the person the junior sailors bring NSTM questions to. Know not just the safety and PMS sections but the troubleshooting tables, the ground fault isolation procedures, the generator paralleling requirements, and the acceptance test criteria for repaired equipment. The EM2 who answers an EMFN's NSTM question from memory and then shows him where the answer lives in the document is the one who develops the junior sailor's self-sufficiency.
  • NSTM Chapter 320 — Electric Motors and Controllers
    The motor maintenance reference. Chapter 320 covers motor insulation testing, winding resistance measurements, overload relay settings, and controller maintenance standards. At EM2, you're executing motor maintenance independently and making the accept-or-repair decision; Chapter 320 is the standard the chief engineer holds you to when a motor you released from maintenance fails the next week.
  • OPNAVINST 4790.4 — Ships' Maintenance and Material Management (3-M) System
    At EM2, you're writing maintenance actions and CSMP entries that go into the ship's permanent maintenance history. OPNAVINST 4790.4 governs what a complete CSMP entry looks like, what triggers a deferred maintenance package, and how the Immediate Superior In Command (ISIC) reads the ship's maintenance record during inspections. An EM2 who understands the 3-M system at the instruction level writes entries the chief doesn't have to rewrite.
  • Naval Nuclear Power School curriculum references (EMN only) — current edition per NNPS
    For EMN EM2s, the qualification procedures and emergency operating procedures for the specific reactor plant you operate are the living reference. The exact documents are plant-specific and command-controlled — but the discipline is the same: know the procedures, know the system responses, know the casualty recovery steps well enough to execute them under pressure at 0200 without looking at the procedure while you're doing it.
  • MILPERSMAN 1430-010 — Enlisted Advancement Requirements
    The EM2 who understands exactly what feeds the advancement score — PMA formula, exam score weight, performance mark average calculation, time-in-rate requirements — is the EM2 who manages his record deliberately rather than hoping the system works in his favor. Read the instruction, understand the formula, and track your own numbers.

Standards — How to Hit Each

  • Evaluation ranking in the top third of the EM2 cohort for two consecutive cycles — the record that feeds the Chief's board.
    The Chief selection board reads the entire record. Two 'Must Promote' or 'Promotable' blocks in the EM2 eval cycles signal a candidate whose peers and superiors both recognized as ready for the Chief's Mess. The behaviors that produce that block: developing junior sailors visible in the narrative, planning and executing major evolutions without being told, and maintaining technical performance while doing both.
  • Nuclear watchstander qualification milestones on the command's expected timeline (EMN) — no deferred boards, no 'behind timeline' entries in the qualification record.
    The qualification timeline is published by the department head and monitored monthly by the division officer. Study the procedures, run casual scenario drills with your peers during off-watch periods, and appear at the formal board fully prepared. The EMN EM2 who takes a deferred board once and bounces back is recoverable; the one who takes multiple deferred boards without improving is in a different career trajectory.
  • NWAE study log built and maintained — six months minimum before the EM1 exam cycle.
    Build the log on paper or in a study tracking app — date, material covered, duration. The LPO who sees the log during a mentorship session is the LPO who allocates study time on the watchbill. A 30-minutes-per-day, four-days-per-week baseline covers the bibliography in two to three months; extend the timeline to six months before the exam cycle and use the extra time for review.
  • Subordinate development output — at least one EMFN or EM3 who completed a PQS section or earned a qualification under your mentorship each evaluation cycle.
    The specific development action — ESWS chapter completed, PMS cross-qual signed, divisional training led — goes in the evaluation input the EM2 writes for the LPO. If it doesn't appear in the input with specifics (who, what qualification, when), it doesn't appear in the narrative. Write the input in the terms the chief uses to describe a promotable petty officer: trained, mentored, qualified, developed.

Technical Mistakes — Concrete Consequences

  • Releasing a generator from maintenance availability without performing the full acceptance test sequence — no-load run, load test, voltage regulation check, frequency stability check.
    A generator released without an acceptance test that then fails on the first full-load demand during an underway replenishment or a general quarters evolution takes the ship from a known-good maintenance record to an immediate casualty with the EM2's name on the release. The chief engineer reviews maintenance-to-casualty histories; the EM2 who shortcutted the acceptance test is named in that review.
  • Signing off an EMFN's or EM3's PQS line for a procedure they haven't actually demonstrated to the standard.
    False certification on a PQS line means a junior sailor shows up at the qualification board, fails the question the EM2 signed, and the board traces back to the signature. On a safety-related qualification — electrical safety, tag-out, de-energization verification — a false certification creates a real injury risk when the incorrectly-qualified sailor works alone. The LPO who finds this pattern in the records has a very short conversation with the EM2 before the matter goes to the division officer.
  • Executing a generator load transfer (shifting load from one generator to another) without verifying the receiving generator can carry the added load before opening the bus tie on the outgoing machine.
    An overloaded generator trips on overcurrent, taking the load it just received plus the load it already carried off the bus simultaneously — a blackout event instead of a planned load transfer. The EOOW reports the blackout to the engineering officer; the maintenance history of the load transfer is in the next investigation. The EM2 who walked through the pre-transfer checklist didn't create the blackout.
  • Allowing a junior sailor to enter an energized switchboard space for any reason without completing the arc flash PPE donning check first.
    The EM2 is responsible for the safety of the sailors under his supervision. A junior sailor who enters a live switchboard space without arc flash PPE because 'it was just for a second' and contacts an energized bus is injured on the EM2's watch. The command safety investigation names the last qualified supervisor in the space — the EM2 who was supposed to enforce the PPE requirement.

Career Decisions at This Rank

  • Pursue the Chief's Mess actively — record-build for selection — or manage a solid EM1 career without the Chief goal
    The Chief selection board is selective and reads the whole record. The EM2 who wants to make Chief needs to understand what the board sees: evaluation narrative blocks ('must promote' vs 'promotable'), warfare qualifications (ESWS / EAWS / dolphins), education (CCAF associate's degree, college credits), leadership evidence (subordinate development, divisional training led, special programs), and sea/shore ratio. An EM2 who is two evaluation cycles in, holds Good High PRT scores, has ESWS, has completed CCAF or is in progress, and has a narrative block that says 'must promote' is in the competitive zone. An EM2 who is coasting at 'promotable' with no warfare pin and no education progress is not. The decision is not all-or-nothing — it's about what you build from this point forward.
  • Accept orders to a demanding sea tour (high-OPTEMPO deployer) or a shore tour with a school
    Sea service is weighted heavily in Chief selection. The EM2 who takes every available sea tour before the Chief board has a sea/shore ratio that signals operational commitment. But a shore tour with a specific C-school or advanced NEC attached — advanced power systems, nuclear supplements, the AC advanced electronics pipeline — can materially improve the technical depth that reads on the next sea tour's eEVAL. The honest analysis: take the school if the school is on paper in the orders; take the sea tour if the shore tour is just a convenient shore duty without a qualification attached.
  • College completion — CCAF associate's degree or a four-year program — while still in
    The CCAF (Community College of the Air Force) equivalent for Navy enlisted is the Sailor/Marine American Council on Education Registry Transcript (SMART) and various Navy College Program pathways. A completed associate's or bachelor's degree before the Chief board is a visible differentiator in a competitive zone. The EM2 with a completed degree and a 'must promote' narrative block is a stronger Chief candidate than the EM2 with the same narrative and no degree. Tuition Assistance covers a significant portion of in-service college credits. Three credits per semester over four years finishes an associate's degree without disrupting the work center schedule.

How the Seat Varies by Unit Type

  • Surface combatant (DDG/CG) — small EM work center
    The EM2 at a small combatant is a significant fraction of the electrical maintenance force. When the EM1 is on leave, you are the answer to every electrical question in the work center. The autonomy is high and the visibility is high — good work and poor work are both immediately obvious. High-OPTEMPO deployment cycles mean the maintenance record matters; you have limited availability windows and must execute them correctly the first time.
  • Nuclear carrier (CVN) — Reactor Department EM2 (EMN)
    The nuclear department EM2 on a CVN is in a separate world. The qualification pipeline is dominant, the chain of command is technically demanding (the chief engineer is a nuclear-trained officer), and the peer group is other nuclear-qualified sailors who set a high technical bar. The evaluation competition is fierce because the nuclear department has strong performers and limited ranking positions. The post-service nuclear plant operator pathway is the defining exit lane and the EMN EM2 who is on timeline for qualifications is building the resume that the civilian nuclear HR departments want.
  • SIMA (Ship Intermediate Maintenance Activity) — shore depot billet
    SIMA EMs see more equipment types in one year than a fleet EM sees in a sea tour — every ship that comes in for an availability period brings a different electrical casualty. The troubleshooting repertoire builds fast. The evaluation culture is different (less OPTEMPO pressure, more process discipline), and the advancement competition includes sailors who have been at SIMA for multiple years and know the shop's workflow cold. An EM2 at SIMA who is building an NEC while developing junior sailors is using the billet well; an EM2 at SIMA who is coasting on the easy hours is falling behind fleet peers who are accumulating sea service and warfare qualifications.

What Good Looks Like at This Rank

The good EM2 is the one the LPO calls before the chief does, because the LPO already knows the EM2 has the situation handled. When a main switchboard maintenance availability is scheduled for next Tuesday, the EM2's work package is on the LPO's desk by Thursday of the preceding week — tag-out sequence written, personnel assigned by name, test equipment identified, EOOW pre-brief time requested. The LPO reads the package, makes two minor edits, and signs it. That is the transaction that produces the evaluation narrative the chief writes without being prompted. His junior sailors' PQS books are the example the LPO shows to the other work centers. Not because the EM2 chased the junior sailors down — because he established a Tuesday/Thursday session routine in month one and stuck to it. The EMFNs in his section know they can bring a PQS question on a Tuesday and get a real answer, not 'find it yourself.' The ESWS board report from the qualification officer names the sailors from his section as prepared candidates. The division officer knows this and writes it into the eval input. On the nuclear track, the chief engineer mentions the EMN EM2 at the propulsion plant training team meeting as a sailor whose board performance reflects preparation rather than just time-in-rate. The qualification board members report he understood the casualty recovery rationale, not just the steps. The EM1 whose job he will eventually do is already watching him during machinery space walkthroughs with quiet approval. The Chief's Mess that selects him three years from now is selecting someone who was already doing the CPO's job at the EM2 paygrade — without the title, without the mess dues, and without being asked.

Preview — The Next Rank

EM1 is Petty Officer First Class — the senior petty officer of the work center. The EM1 doesn't execute maintenance in the same way the EM2 does; he executes it by knowing where it stands and ensuring the EM2s and EM3s and EMFNs below him are executing it correctly. The shift from EM2 to EM1 is the shift from doing-plus-supervising to planning-plus-accountable-for-outcome. The EM1 who is in the switchboard space doing the PMS card himself while two EM3s stand around watching has failed at his fundamental job. The Chief's Mess conversation starts becoming real at EM1. The Chief is watching every EM1 in the department as a potential CPO selectee. The ones who make the Chief's board competitive are the ones who demonstrate that they can run a work center — manage the maintenance schedule, develop the junior sailors, interface with the LPO and the division officer as a professional who brings solutions rather than problems, and maintain technical authority without technical micromanagement. The EM1 who walks into the Chief's Mess after selection has been doing the CPO's job at the EM1 paygrade for at least a year. The board can tell the difference.
