FC vs AB
Fire Controlman (USN) vs Aviation Boatswain's Mate (USN)
Two rates that pass each other in the P-way daily and have zero comprehension of what the other one does for 12 hours.
In the recruiter's version: the FC would maintain the fire control systems that make Navy guns and missiles accurate, and the AB would work on the flight deck of an aircraft carrier. In the version where people actually serve: cIC — Combat Information Center — is your professional home. And for the AB: jet blast, spinning propellers, arresting cables under tension, and aircraft moving in every direction — all on a pitching deck in the middle of the ocean. The recruiter's version had better production value. This version has better accuracy. Same DD-214 at the end. Very different stories about what happened between the raise-your-right-hand and the out-processing.
After the Uniform

Recruiter vs. Reality
The pitch versus what people who actually did the job report back.
“You'll maintain the fire control systems that make Navy guns and missiles accurate — Mk 86 gunfire control, AEGIS weapon system components, and the targeting radar and computer systems that transform a weapon into a precision weapon. AEGIS-qualified FCs develop the most specific and commercially valuable skillset in surface warfare electronics: Raytheon and Lockheed Martin's AEGIS contractors know exactly what an experienced AEGIS FC brings and hire them into technical representative and program support positions that start well above junior technician pay. The weapons fire control background also transfers to defense electronics broadly, and cleared weapons systems technicians are consistently in demand.”
The Aegis combat system is the most capable surface warfare system in the world and you will be the person who keeps it calibrated, functional, and ready to do the thing it is designed to do, which is intercept ballistic missiles. The SPY-1D radar on an Arleigh Burke-class DDG is a phased array system with capabilities that are genuinely classified at levels your recruiter could not have described, and maintaining it involves a technical depth that A and C school only partially prepares you for — the rest is experience, tech manual reading at 0200, and asking the FC chief things the manual doesn't cover. CIC — Combat Information Center — is your professional home. It is dark, cool, full of screens, and the single most important space on the ship during actual operations. General quarters puts you in a specific seat in front of a specific console doing a specific thing that matters enormously. The defense contractor path after separation is one of the clearest of any rate. Raytheon, Northrop, Lockheed maintain Aegis on contract and they hire FCs. The systems knowledge is specific, documented, and valued in a way that generalist technical rates sometimes are not.
“You'll work on the flight deck of an aircraft carrier — one of the most dangerous and adrenaline-fueled workplaces on earth. ABs launch and recover fighter jets, manage jet fuel operations, and direct aircraft weighing 60,000+ pounds in spaces tighter than a parking lot. It's the closest thing to a controlled disaster the Navy runs every day.”
The flight deck will try to kill you. Jet blast, spinning propellers, arresting cables under tension, and aircraft moving in every direction — all on a pitching deck in the middle of the ocean. The work is physically brutal, the hours are relentless during flight ops, and the safety stakes are absolute. One wrong step and you're a statistic. The ABs who thrive love the intensity and take genuine pride in the fact that nothing flies without them. The civilian airport and aviation fueling industry hires from this background, but nothing on the outside matches carrier flight ops.
The Real Life
Same dimensions, side by side. FC on the left, AB on the right.
Operating and maintaining the ship's weapons systems — AEGIS, missiles (SM-2, SM-6, Tomahawk), CIWS, and the 5-inch gun. FCs are the trigger-pullers of the surface fleet. On a ship: standing weapons system watches in CIC, running combat system exercises, and performing maintenance on fire control systems. The work is technical, high-stakes, and operationally central.

A School at Great Lakes (IL) is about 22 weeks. Covers fire control fundamentals, missile systems, radar theory, and computer-based weapons systems. C School for AEGIS-specific training adds several more weeks at Dahlgren (VA). The training is demanding and heavily technical.
—
Low to moderate. Most work is in CIC (Combat Information Center) operating weapons systems consoles. Some physical maintenance on missile launchers and gun mounts.

Fire Controlman is one of the best-kept secrets for civilian career potential in the surface Navy. The recruiter will tell you about operating weapons systems — and the AEGIS combat system is genuinely one of the most sophisticated weapons platforms in the world. What they won't tell you: you will spend most of your time maintaining systems, not firing them. The planned maintenance system (3M) is a constant companion. Sea duty is demanding — destroyers and cruisers deploy frequently and the ships are not large. But the payoff is real: AEGIS-qualified FCs are in extreme demand at defense contractors. Lockheed Martin essentially built AEGIS and has a continuous pipeline for former FCs. If you can handle the sea time and stay technically sharp, FC sets you up for a strong civilian engineering technician career in defense.
