AST vs IT
Aviation Survival Technician (USCG) vs Information Systems Technician (USN)
One fights wars at sea. The other fights drug cartels, pollution, and drunk boaters — simultaneously and in the same afternoon.
If AST had a warning label: the candidates who make it are self-selected for the specific combination of physical capability, calm under pressure, and water competence that open-ocean rescue requires. If IT had one: shipboard systems include ADNS (Advanced Digital Network System) and SCI networks that require clearance to touch and patience to maintain. Neither job comes with a warning label. Both probably should. A recruiting station near you is currently presenting both of these as "the best-kept secret in the military."
After the Uniform
The part the recruiter skips: what each job actually translates to once you're a civilian — and what it pays.

Recruiter vs. Reality
The pitch versus what people who actually did the job report back.
“ASTs are Coast Guard rescue swimmers — the people who jump out of helicopters into hurricane-driven seas to pull survivors out of the water. 'So Others May Live' is the rescue swimmer motto and it means exactly what it says. The AST pipeline is physically demanding, the washout rate is real, and the job is genuinely one of the most heroic in any branch. Flight pay, special duty pay, and a mission that will be on the evening news when you do it well.”
Rescue swimmer school is physically and psychologically demanding with intentional attrition. The candidates who make it are self-selected for the specific combination of physical capability, calm under pressure, and water competence that open-ocean rescue requires. Once you're wearing the rescue swimmer wings, the job is exactly what it says: you jump into conditions that are actively trying to kill the people you're rescuing, and you bring them back. The trauma exposure and the psychological weight of rescue swimmer operations are real career features that the Coast Guard is improving its support for. The flying hours and the rescue swimmer credential are genuine differentiators in civilian aviation and search-and-rescue careers.
“You'll manage Navy network infrastructure and information systems — routers, switches, servers, and the communication architecture that connects ships and shore installations to each other and to the broader naval network. The shipboard IT environment is hard on equipment and harder on the people maintaining it under operational pressure, which means IT veterans who've managed Navy networks have a problem-solving resilience that enterprise IT employers recognize. Security clearance plus CompTIA Security+ and Network+ plus operational Navy IT experience is a competitive federal IT contractor profile. Government IT organizations and managed services providers recruit Navy IT veterans consistently and the clearance is a meaningful differentiator in the federal market.”
You are the person who resets passwords for people who swear they didn't change anything, aboard a ship where going home after work is not an option because the ship is the home. The Navy's IT infrastructure ranges from modern and well-maintained at major shore installations to 'this router is from when this ship was commissioned and we can't update the firmware because the one critical application only works on the old firmware,' and you will experience both in the same career. NMCI — the Navy Marine Corps Intranet — is the enterprise network you will support ashore, and it is a massive IT infrastructure managed by HP/DXC on contract, which means you will learn to navigate both Navy bureaucracy and contractor bureaucracy simultaneously. Shipboard systems include ADNS (Advanced Digital Network System) and SCI networks that require clearance to touch and patience to maintain. CompTIA Security+ is mandatory. CCNA is common. The Help Desk tickets will range from 'my CAC reader isn't working' (it's upside down) to 'the entire ship's network is down and the XO is asking why.' The six-figure civilian IT job is real. The Security+ is real. So is earning it.
The Real Life
Same dimensions, side by side. AST on the left, IT on the right.
—
Network administration, server maintenance, SATCOM operations, and help desk support. On a ship: you are the IT department for 300-5,000 people, working in a server room that might be 100°F. Shore duty: more structured, 8-hour days, and the chance to work on larger enterprise networks.

A School at Corry Station (Pensacola, FL) is about 24 weeks. Covers networking, system administration, SATCOM, and cybersecurity fundamentals. The pace is manageable and Pensacola is a pleasant training location.

Low. IT work is desk-based. Shipboard life involves navigating ladders and tight spaces, but the job itself is sedentary.
—
Navy IT is a solid, reliable path to a civilian tech career. The recruiter will tell you it's like being an IT professional — and it largely is, just on ships and submarines sometimes. What they won't emphasize: sea duty is the deal-breaker for many. You will spend 3-4 years on a ship, and IT on a ship means being on call 24/7 when systems go down. The server room is hot, the equipment can be outdated, and you are responsible for everything from email to satellite communications. Shore duty is much more like a normal IT job. The civilian translation is strong — Security+ and military IT experience get you hired — but you have to supplement with modern certifications because the Navy still runs a lot of legacy systems.
