ETE1-E3

Electronics Technician

E-1 to E-3 (Junior Enlisted) · Coast Guard

E1–E3E-4E-5E-6E-7E8–E9
HEADS UP

You are in the pipeline for the most technically demanding rating in the Coast Guard enlisted force. The A-school seat at TRACEN Petaluma or Yorktown is competitive and the selection reads your PQS completion, your EER trajectory, and your OIC's endorsement. The ET who spends the non-rate phase learning the gear instead of learning the watch schedule arrives at schoolhouse already speaking the language — and the ET who doesn't is playing catch-up for 26 weeks in a course that does not slow down for passengers.

The Honest MOS Read
The non-rate-through-striker phase of the ET pipeline is the part the recruiter glosses over. You came out of TRACEN Cape May after eight weeks, you have a uniform and a desire to work on electronics, and you have been assigned to a cutter, a small boat station, a sector communications unit, or a shore electronics facility as an undesignated Coastie. The Coast Guard does not have enough school seats to send every interested member through A-school the week after boot camp. Some members get a direct pipeline designation and hit A-school within months; others spend a year or more at first unit striking for the rating, doing the work of a non-rate while building the qualification and evaluation record that earns the designation. If you are reading this in the second category, that is not a consolation prize — it is the phase where the best ETs in the rating often get built. Your first-unit environment depends on where you get stationed. A cutter billet puts you in a tight-quarters crew environment where the ET shop is a small group of petty officers maintaining the vessel's entire electronics suite — radar, VHF/HF/MF communications, GPS and GNSS navigation, IFF transponder and interrogator, GMDSS distress equipment, AIS transponder, internal communications, and the rest of the electronics infrastructure that allows a Coast Guard vessel to see, hear, and talk. A shore station or sector communications unit puts you in a more office-like billet, potentially supporting maritime domain awareness infrastructure, shore-based VHF networks, or communications center operations. Both environments teach you something the schoolhouse cannot: what the equipment looks like when it is actually installed and being used, not when it is on a training bench. The daily work at this phase is honest and unglamorous. You clean antenna feeds. You sort coax runs. You pull watch in the electronics equipment room. You stand the details and duty-section rotations that fill the bottom of every watchbill. You hand the ET2 the correct tool before being asked, because you read the service manual the night before and you know which measurement they are about to take. None of this is on the rating badge. All of it is on the record that earns you the A-school endorsement. The GMDSS framework is the backdrop to everything the ET rating does, and you should understand it even before schoolhouse. GMDSS — the Global Maritime Distress and Safety System — is the ITU-framework distress and safety communications system mandated for most SOLAS vessels. It specifies distress equipment categories (EPIRBs, SARTs, DSC controllers, NAVTEX receivers), distress frequencies (156.8 MHz VHF Channel 16, 2182 kHz MF, 406 MHz EPIRB), and maintenance requirements. Coast Guard vessels operating in GMDSS-mandated sea areas are required to carry and maintain this equipment. The ET rating is the rating that maintains it. The GMDSS Radio Maintainer endorsement under FCC 47 CFR Part 13 is the civilian credential that proves you can do so, and it is the credential the rating community treats as a professional floor. You are not sitting for that exam as a non-rate — but you should know it exists, know what it covers, and begin orienting your study toward it. The RF safety dimension of this rating is not abstract. You are working in proximity to transmitting antennas on a small vessel. The VHF and HF transmitters your unit operates emit real RF energy at power levels capable of causing thermal injury at close range. The antenna masts and rigging on Coast Guard cutters and small boats are hazardous when transmitters are in operation. The ET rating's first operational safety obligation is understanding where the RF hazard zones are at your unit, how the transmit-inhibit and lockout procedures work, and what the keying procedures are before anyone goes aloft. You are learning this now, as a non-rate, not because someone will test you on it but because the alternative is being on the wrong end of a mishap report before your first SWE cycle. The PQS — Performance Qualification Standard for the ET rating — is your qualification roadmap from non-rate to ET3 designation. Every task in the PQS maps to something you will be expected to demonstrate at A-school or perform on the deckplate. The non-rate who arrives at Petaluma or Yorktown with a PQS partially signed across real systems is ahead. The one who arrives having only looked at the cover page is behind. Work the PQS with the petty officers in your shop, not as paperwork to be completed but as a learning contract against the equipment you are standing next to every day.
Career Arc
  • 01Check in to first unit as a non-rated Coastie — receive shop orientation, read the electronics equipment room standing orders and RF-hazard zone markings, begin PQS work under supervision of the ET shop petty officers
  • 02First supervised maintenance assist — antenna connector inspection, transceiver cleaning, cable management — logged in the unit's maintenance management system with the signing ET's entry, your name in the assist field
  • 03PQS progress checkpoint — OIC or ET shop supervisor endorses continued A-school candidacy based on PQS completion rate, EER trajectory, and physical readiness; this endorsement is the gating item for the A-school slate
  • 04A-school designation approved — class date assigned to TRACEN Petaluma (ET primary electronics A-school location) or TRACEN Yorktown depending on scheduling; travel arrangements coordinated through the unit admin office
  • 05TRACEN Petaluma or Yorktown ET A-school — 26-28 weeks (verify current course length against NETC/CG Institute course catalog); covers electronics theory, RF systems, radar, GMDSS, communications, navigation electronics, test and measurement, system-level troubleshooting
  • 06A-school graduation and ET rating designation — report to first rated unit as ET3 (E-4); the rating badge is now sewn on and the maintenance signature authority begins with the first work order
Common Screwups
  • ×Conduct incident before the A-school designation — a DUI, a barracks fight, a positive urinalysis, or a civil legal matter surfaces during the non-rate phase and gets in front of the OIC who was about to sign the A-school endorsement. The endorsement does not go forward. A conduct finding at E-1 through E-3 is not automatically disqualifying for everything, but it is disqualifying for the competitive A-school slate at exactly the moment it matters most.
  • ×Falsifying PQS signatures — signing yourself off on PQS tasks you did not actually demonstrate, or getting a shipmate to sign off on items they did not witness you perform. A-school cadre and unit supervisors at first rated assignment cross-check the PQS against actual experience; the non-rate who fabricated qualifications is exposed at the first sign-off attempt on something they clearly do not understand. The falsification finding is the permanent record, not the failed sign-off.
  • ×RF-hazard incident caused by negligence — entering an antenna hazard zone during a transmit cycle without clearance, touching transmitter output terminals without a lockout, or keying a transmitter without verifying the antenna is clear. The injury potential is real; the mishap report is permanent; and the investigating officer interviews the ET shop chain in detail. The non-rate whose name appears in the root cause box is not advancing to A-school on any near-term timeline.
  • ×Financial mismanagement that reaches the chain — payday-loan spirals, unpaid credit accounts that generate collection contacts to the unit, military pay garnishment. The Chiefs Mess at a small unit notices when a member's financial situation is generating administrative traffic, and the OIC who is being asked to endorse the A-school candidacy is also the OIC who is managing the member's financial counseling referral. These two facts interact badly.
  • ×OPSEC breach related to unit electronics — posting a photo from the electronics equipment room, the CIC, or any compartment showing radio configurations, frequency plans, cryptographic equipment, or antenna infrastructure. The non-rate who puts this on Instagram is educating adversary SIGINT analysts about CG platform configurations. The investigation is initiated by the unit security officer within 24 hours of discovery.

A Day in the Life

  • 0530-0600Wake and prepare for morning quarters. Check the ship's plan of the day or the unit's daily schedule for any electronics maintenance events or special evolutions that affect the equipment room — this tells you whether the ET shop is doing planned maintenance before 0900 and whether you need to have anything staged.
  • 0600-0630Morning quarters — muster, uniform inspection, and the day's plan from the OOD or the unit supervisor. Write down any tasking you receive for the electronics shop.
  • 0630-0800Clean and setup — electronics equipment room cleaning rotation, antenna connector wipe-down if scheduled, cable management tidying in the rack bay the ET2 assigned you to last week. Not glamorous. Do it without being told and do it right.
  • 0800-1000Maintenance assist with the ET shop — shadow an ET3 or ET2 on a scheduled MPC, hold the test lead, write the readings, hand the tool. Read the MPC in the hour before so you know what test point comes next.
  • 1000-1130PQS work — find the ET1 or ET2 for a sign-off on a task you have actually performed. One sign-off per week, on something you can demonstrate. Do not push for signature on items you have only observed.
  • 1130-1230Lunch. Eat in the mess deck or galley. As a non-rate, you are at the bottom of the mess hall routine — accept that and be useful to whoever shares the table.
  • 1230-1500Afternoon work — duty section assignments, administrative tasking, or a second maintenance assist if the shop has a corrective maintenance package open. If the afternoon is quiet, pull out the COMDTINST M10550.1 and read the chapter the ET2 mentioned last week.
  • 1500-1700Study — PQS review and GMDSS vocabulary work. Write out the three primary distress frequencies from memory (156.8 MHz / 2182 kHz / 406 MHz). Read the applicable equipment manual chapter for the system the shop is working on this week. Keep a study notebook, not just a memory.
  • 1700-1800Secure from work day — clean work area, return any borrowed tools to the tool crib, check the next day's plan of the day for any 0600 electronics events. Make sure the equipment room is locked and secured properly.
  • 1800-2000Evening — personal time, physical training if the unit PT schedule permits, or continued PQS study. The ET3 who advanced in 18 months was doing something productive in this window; the one who advanced in 36 months was not.
  • 2000-2200If duty section: standing the electronics equipment room watch or the duty section rotation as assigned. If not duty: study or rest. The A-school pipeline is 26 weeks of technical instruction at a pace that demands you arrive with habits already formed.

Weekly Cadence

The non-rate week runs on the unit's schedule, not the ET shop's. Monday through Friday there is a general quarters routine, a duty rotation, and a work schedule that spans deck divisions, engineering details, and administrative tasking — with the ET shop maintenance block occupying a slice of the afternoon most days. The weight of your week falls in the maintenance-assist windows: the two or three hours each day when you are actually in the electronics equipment room, doing the work that translates to PQS signatures and EER bullet points. That is the professional development time. Treat it that way. The rhythm shifts when the cutter is at sea or when the station runs an extended operational schedule. At sea, the electronics equipment room is more active — the gear is being worked harder, failures happen, and the ET shop runs corrective maintenance in parallel with the operational schedule. Your value in that environment is in being able to hand the right tool, write the correct log entry under supervision, and not create additional problems while the ET2 is trouble-shooting. The petty officer who trusts the non-rate in the equipment room during a sea-state maintenance event is making a judgment call based on what they saw from that non-rate in port. Build the reputation in port. Physical training runs Monday, Wednesday, and Friday at most units. Wednesday is often a group run. The PFT cycle repeats on a schedule the unit's administration communicates at the start of the evaluation period. The non-rate who is above the minimum fitness standard at every PFT has removed one variable from the OIC's endorsement calculus. The one who fails a PFT during the non-rate phase is explaining the failure at the exact moment the endorsement is being considered.

Key Skills — How to Drill Each

  1. 01
    Identify and locate every major electronics system on your unit — VHF/HF/MF transceivers, X-band and S-band radar, GPS/GNSS receivers, IFF transponder/interrogator, GMDSS distress equipment including EPIRB and DSC controller — by compartment, rack, and power bus.
    Walk the unit systematically with the ET2 your first week. Ask to trace the coax from each antenna to each transceiver input. Ask which power bus feeds each equipment rack. Draw the signal flow on a notepad — antenna → coax run → waveguide → transceiver input — for each major system. The non-rate who can walk a visitor to any piece of electronics gear on the unit without looking at a deck plan has done this work; the one who cannot hasn't. The PQS item that asks you to identify the equipment exists precisely because knowing where the gear lives is the prerequisite for every subsequent skill.
  2. 02
    Assist a qualified ET with a scheduled preventive maintenance check — antenna VSWR measurement, transmitter power output check, receiver sensitivity check, antenna connector inspection — using the applicable equipment maintenance manual procedure.
    Before the maintenance event, read the MPC (Maintenance Procedure Card) or service manual procedure for the specific check you are assisting. Know what tools are required. Know what the pass/fail criteria are. When you arrive at the work site, hold the test lead, hand the instrument, and write the readings — but do not pretend to understand a result you do not understand. The ET2 would rather hear 'what does that VSWR number mean?' than find out at the log entry that you wrote the wrong unit. The most valuable thing you do at this stage is demonstrate that you follow procedure and you say what you don't know.
  3. 03
    Handle basic RF and electronics test equipment — digital multimeter, VSWR/return-loss bridge, signal generator, spectrum analyzer if the shop has one — without damaging a connector, a component, or a calibrated instrument.
    Calibrated instruments are expensive and the calibration label is the certification that makes the measurement meaningful. Handle the calibration sticker with the same care you handle the instrument: do not let anything touch it, do not store a calibrated instrument loose in a toolbox, and do not connect test cables to a transmitter output without first verifying the instrument's power input range against the equipment's output specification. The non-rate who damages a spectrum analyzer input by connecting it to an unattenuated transmitter output has created a shop problem that takes weeks and a purchase request to resolve — and the damage was entirely preventable by reading one line of the instrument's specification.
  4. 04
    Read a wiring diagram, a block diagram, and an equipment configuration drawing well enough to trace a signal path and identify where a cable run enters and exits a chassis.
    Start with block diagrams, which show the major functional blocks and the signal path between them, before you try to read full wiring diagrams. The block diagram for a VHF transceiver — antenna port → preselector → mixer → IF amplifier → detector → audio output — is something you can understand before you have touched the equipment. When you can trace the signal path on the block diagram with your finger while the equipment is open in front of you, you are ready to start cross-referencing the wiring diagram. Electronics theory from the A-school pipeline matters, but the ability to read a diagram and find the path is more immediately useful to the shop than theory.
  5. 05
    Maintain your PQS completion, study the COMDTINST M10550.1 Electronics Manual, and build the basic GMDSS vocabulary — distress frequencies, equipment categories, DSC calling procedures — before arriving at A-school.
    The A-school seat at Petaluma or Yorktown goes to the non-rate the OIC endorses; the OIC endorses the one who has demonstrated both readiness and initiative. Work the PQS line by line with your shop supervisor and get signatures on items you have actually performed. Separately, read COMDTINST M10550.1 — not to memorize it but to understand the structure of the maintenance system the ET rating operates under. And pull the ITU Radio Regulations or a plain-language GMDSS guide and learn the distress frequencies cold: 156.8 MHz (VHF Channel 16), 2182 kHz (MF international distress), 406 MHz (EPIRB). These are the numbers every ET in the rating knows without looking them up.

Manuals & References — What Chapters Matter

  • COMDTINST M10550.1 (current series) — Coast Guard Electronics Manual
    This is the governing document for every electronics maintenance action, installation standard, and equipment configuration on Coast Guard platforms. At the non-rate stage, focus on the general sections covering maintenance management, RF safety, hazardous energy control (lockout/tagout), and the documentation requirements for maintenance entries. The format and standards of a compliant maintenance log entry are defined here — know this format before you make your first assist entry.
  • ITU Radio Regulations (current edition) — Part II: Frequencies and Appendices related to GMDSS
    The GMDSS frequency allocation framework, distress channel designations, and equipment category definitions that govern what your equipment must do. At this stage, the most relevant content is the designation of the three primary GMDSS distress frequencies (156.8 MHz / 2182 kHz / 406 MHz), the EPIRB operational requirements, and the DSC calling procedure basics. You do not need to read the full ITU Radio Regulations as a non-rate — but you need to know GMDSS exists as a framework and why it drives the ET rating's daily maintenance obligations.
  • ET Rating Performance Qualification Standard (PQS) — current edition from the CG Institute
    The PQS is your qualification roadmap from non-rate to A-school designation. Every task in it represents a real skill the ET shop uses. Work through it with your supervisor — not as paperwork but as a learning contract. The PQS items that require watching a qualified ET perform a task are designed for first-unit exposure; the items that require you to demonstrate the task yourself are the bar for the A-school endorsement.
  • Unit electronics equipment room standing orders and RF hazard zone markings
    Read these the first week you check in, before anything else. The RF hazard zones around your unit's transmitting antennas, the lockout/tagout procedures for the transmitters, and the antenna clearance procedures for maintenance aloft are the safety framework your rating operates inside. An RF thermal injury or high-voltage contact injury before you arrive at A-school ends the candidate pipeline; none of these incidents are surprising in retrospect — they all follow from a non-rate who did not read the standing orders.
  • COMDTINST M1000-series — Coast Guard Personnel Manual, relevant sections on A-school eligibility, advancement, and EER
    You need to understand the process by which A-school designations are approved, the EER cycle and how your evaluation supports the endorsement, and the conduct standards that affect eligibility. The administrative path to the A-school slate is not something the chief explains to you automatically — read it yourself and own the calendar.

Standards — How to Hit Each

  • A-school designation to ET, with OIC endorsement and a class date at TRACEN Petaluma or Yorktown. The seat is competitive; EER trajectory, PQS completion, and physical readiness are the deciding variables.
    The OIC endorsement for the A-school designation is a performance evaluation, not a bureaucratic form. Make your EER input easy to write in your favor: show up to everything on time, keep your uniform clean for quarters, complete assigned PQS tasks ahead of the deadline, and ask one useful technical question per week in the ET shop. The non-rate who does these four things consistently for twelve months earns the endorsement. The one who is waiting for a more convenient time to start usually doesn't.
  • Coast Guard Physical Fitness Test (PFT) passed every cycle and weight/body composition compliant with COMDTINST M1020.8 throughout the non-rate phase.
    The PFT at the non-rate level is the floor, not the goal. The ET rating works in antenna masts, equipment bays, equipment rooms with no climate control, and shipboard spaces that require crawling, reaching, and lifting. Get above the minimum fitness standard while you have the time and energy — once the maintenance schedule owns your day, the PT time disappears. The non-rate who is already in shape when the workload increases keeps pace; the one running the minimum who then adds sea watch rotation and 12-hour maintenance days falls apart.
  • Clean conduct record and no civil or military legal incidents throughout the non-rate phase.
    The A-school endorsement is a discretionary act by the OIC. A conduct finding, NJP, or civil legal matter at any point before the endorsement is signed gives the OIC a reason to withhold it — and on a competitive slate, the reason does not need to be major. The standard here is simple: do not give the OIC a reason to look for the next candidate on the list.
  • RF safety: zero antenna-hazard incidents, zero unauthorized contact with energized high-voltage equipment, zero lockout/tagout violations.
    Before you do anything near a transmitter, antenna structure, or electronics cabinet, ask. Not apologetically — directly. 'Is this transmitter locked out before I open this cabinet?' is a question that takes 10 seconds to ask and a mishap report to not ask. The qualified ETs in your shop have been doing this long enough that the hazard controls are automatic for them; you are at the stage where they are not yet automatic, which is exactly when incidents happen.

Technical Mistakes — Concrete Consequences

  • Keying a transmitter without verifying that the antenna is clear of personnel and that no antenna maintenance is in progress.
    The RF energy from a shipboard VHF or HF transmitter at close range causes thermal burns. The investigation board asks who keyed the transmitter, who was responsible for the lockout, and what the antenna clearance procedure said. If you keyed the transmitter, your name is on the incident report permanently, and the chief who was considering your A-school endorsement is now managing an injuries and mishap case instead.
  • Touching high-voltage assemblies — transmitter PA stages, radar magnetron or TWT assemblies, power supply filter capacitors — without explicit clearance from a qualified ET and verified lockout/tagout.
    The stored charge in a radar transmitter's high-voltage supply can be lethal minutes after the transmitter is de-energized, because the filter capacitors hold charge after power is removed. The non-rate who opens the transmitter cabinet without a complete lockout and discharge verification is trusting their life to an assumption. The COMDTINST M10550.1 hazard controls are specific about this for exactly this reason.
  • Logging a maintenance assist entry for work you did not observe or cannot account for.
    The maintenance log is a legal record of what was done. An assist entry with your name certifies your presence and participation in the action. A falsified assist entry — entered because the paperwork needed a second name and you were available — is a documentation integrity violation. The COMDTINST M10550.1 maintenance record audit finds the gap when the entry date does not align with your watch schedule. The ET shop OIC reports the discrepancy.
  • Disconnecting a coax run on a transmitter output without verifying the transmitter is de-energized and the system is locked out.
    A mismatched termination on an energized transmitter output destroys the final amplifier stage in milliseconds. The power amplifier in a shipboard HF or VHF transmitter is not a cheap component — the damage is expensive, the equipment is potentially inoperable until the part requisition clears, and the cause of failure traces to the last person who touched the coax connection. If the transmitter is on the GMDSS watchbill for that sea area, the unit has a GMDSS casualty for the duration of the repair.
  • Discussing unit communications configurations, antenna installations, cryptographic keying equipment, or radio frequency assignments on any personal device or social media platform.
    The electronics equipment room is one of the highest-security spaces on any CG platform. The specific frequencies, equipment models, and cryptographic architecture of your unit's communications suite are operationally sensitive. A photo from the equipment room or a description of the comms architecture posted on a social platform is an OPSEC incident, not a minor judgment lapse. The security investigation begins when the post is discovered; the content cannot be unposted.

Career Decisions at This Rank

  • Push for a direct A-school pipeline designation versus accepting the striking-for-rating path at a first unit.
    Not every ET comes to the rating with a guaranteed pipeline slot. Some members designate ET on the enlistment contract and receive a direct A-school date; others arrive at a first unit as non-rated members and must earn the designation. If you are in the second group, the striking path is not a worse path — the ET who spends 12 months at a real unit before schoolhouse often retains more of the A-school curriculum because they have already seen the equipment. But the striking path requires active career management: work the PQS, build the EER, communicate intent to the chain, and make the OIC's endorsement decision easy. The member who assumes the designation will happen without effort usually discovers they are wrong at the moment when the A-school slate posts.
  • Whether to pursue the FCC study track during the non-rate phase or defer until post-A-school.
    The FCC GMDSS Radio Maintainer endorsement and the General Radiotelephone Operator License (GROL) under 47 CFR Part 13 are the civilian professional credentials the ET community treats as a professional floor. You cannot sit for the GMDSS Maintainer endorsement without the experience and training background the A-school provides, but you can begin building GMDSS vocabulary and electronics theory that makes A-school more productive. If you have time at first unit and motivation, pull the GROL study guide. The non-rate who arrives at Petaluma with electronics theory already partially loaded retains more and scores higher. The one who defers everything to schoolhouse is doing fine — but the one who pre-loads is doing better.
  • Whether to request a cutter billet versus a shore station for first unit.
    Both environments develop the ET. Cutter billets put you in a tight-team electronics shop on a vessel that actually uses the radar, comms, and navigation equipment the ET rating maintains; you see the equipment under operational load, you see casualties in real-time, and the shipboard experience is a career resume line that shore-only billets cannot replicate. Shore stations and sector communications units offer more regular hours, more stability for family situations, and sometimes broader exposure to communications infrastructure. There is no objectively correct answer here — the answer depends on your life circumstances and career goals. What you should not do is decide based on whichever seems less demanding. The ET rating is not a demanding-optional rating.

How the Seat Varies by Unit Type

  • Cutter (National Security Cutter, WMEC, or FRC/Sentinel-class)
    The cutter electronics shop is the ET rating in its most concentrated form. NSCs and WMECs have multi-tech ET shops running full preventive and corrective maintenance programs across radar suites, HF/VHF/MF communications, GMDSS, IFF, AIS, and internal communications. Sentinel-class FRCs have smaller crews and a correspondingly smaller ET footprint. As a non-rate on a cutter, you work in the electronics equipment room, the CIC, and sometimes aloft on antenna inspections. The operational tempo means the gear gets used hard, casualties happen, and the shop never has a maintenance-optional day.
  • Small Boat Station
    Small boat stations are typically smaller-crew operations where a single ET petty officer may be the entire electronics maintenance presence, or where the station relies on a sector electronics unit for heavy maintenance. As a non-rate striking for ET at a small boat station, you may get less shop-floor time than at a cutter, but you get broader exposure to the operational mission — SAR case management, law enforcement boarding support, ATON — that contextualizes why the communications and navigation electronics matter. The RF-hazard environment is different: smaller boat-mounted antennas, lower transmitter power levels, but the same procedural obligations.
  • Sector Communications Unit or Shore Electronics Facility
    Shore-side electronics billets — sector communications centers, marine safety offices with electronics functions, district electronics maintenance facilities — offer a more infrastructure-oriented environment. You may be working on shore-based VHF networks, maritime domain awareness display systems, AIS receivers, or the communications infrastructure that supports the CG's operations center. The GMDSS framework is still relevant here because shore-based GMDSS networks (DSC coast stations, the SAR satellite link infrastructure) are part of the system. The day is more regular, the facilities are better, and the equipment diversity may be broader than a single cutter.
  • Aviation Support Billet (non-AET, but with electronics exposure)
    Some non-rates at air stations see electronics maintenance work in the context of aviation ground support — communications equipment, radar systems, or facility electronics maintenance — even if they are not in the AET pipeline. If you find yourself at an air station as a non-rated member striking for ET, clarify your pipeline path early: the AET and ET ratings have different A-schools and different skill sets. The AET pipeline focuses on airborne avionics and airworthiness; the ET pipeline focuses on shipboard and shore communications and navigation. Both are excellent — but you need to be in the correct pipeline for your assignment and your goals.

What Good Looks Like at This Rank

The good ET striker is the non-rate who shows up to the electronics equipment room on a Tuesday afternoon — not because anyone scheduled them there, but because the ET2 mentioned at lunch that the antenna connector inspection was tomorrow morning and they wanted to read the procedure before they touched anything. When the ET2 arrives at 0700, this striker has the service manual open to the correct page, the connector cleaning kit staged, and two questions about the VSWR acceptance criteria ready to ask. That is not ambition performing for an audience. That is orientation — knowing that the A-school endorsement is an evaluation of every day in the shop, not just the evaluation period. The observable markers at this rank: PQS is signed on real tasks, not padded with items they watched from across the room. The RF hazard zones at the unit are known by memory, not by needing to be reminded each time. When the electronics equipment room has a visitor, this non-rate can identify every major system in the compartment by function and name. Their EER input blocks are clean because the ET petty officers writing them have noticed that the work output is consistent whether or not the chief is watching. The ETC knows this non-rate's name before the A-school designation endorsement is submitted. Not because of a notable accomplishment, but because the ET shop functions slightly better with this person in it than without. That reputation — built in the unglamorous phase, doing the work that nobody announces — is the foundation the whole ET career gets built on. It is also the easiest phase to build it in, because the bar for a non-rate is relatively low and the daily competition for it is against yourself.

Preview — The Next Rank

ET3 is the first rated paygrade in the ET pipeline, and the transition from non-rate to ET3 is not gradual — it is a step change. You go from assisting and observing to signing. The maintenance log entry with your name as the performing technician is a legal certification of work quality, and it appears on the first package you close at your first rated unit. The A-school pipeline at Petaluma or Yorktown runs 26-28 weeks and covers electronics theory, RF systems, radar alignment and maintenance, GMDSS installation and maintenance, HF/VHF/MF communications systems, GPS and navigation electronics, IFF systems, and test and measurement procedures. You will be tested in the classroom and evaluated in the lab. The first thing the ET2 at your post-A-school unit wants to know about you is how you handle the fault isolation procedure when the radar has a casualty at 2200. Not what your A-school GPA was. The answer to that question is built in the first 90 days of the rated assignment: follow the service manual, document as you go, and ask the right question at the right step instead of substituting a guess. The ET3 who builds that reputation in the first 90 days is the one the shop promotes into the independent-tech billet at 18 months. The one who skips steps earns a reputation that is much harder to change than it was to avoid.
