1110 vs 1120
Surface Warfare Officer (USN) vs Submarine Warfare Officer (USN)
Same ocean, same Navy chow, same creative interpretation of "sleep schedule" — wildly different definitions of a bad day.
The 1110's typical grind: your 'tactical maritime operations' are standing watch on the bridge at 0300, staring at a radar screen, and praying that the contact bearing 270 is a fishing boat and not something with a targeting radar. You'll qualify as OOD, learn to conn the ship, and discover that the ocean is simultaneously beautiful and actively trying to kill you. Different MOS, different problems, same pay grade: The 1120's version of "work": your 'submarine warfare' is weeks of boredom punctuated by moments of pure adrenaline when you're running from something or running toward something, and you can't tell your family about either. You'll qualify to run a nuclear reactor, navigate underwater without GPS, and sleep in a rack the size of a coffin. Two jobs that theoretically answer to the same Commander-in-Chief but have clearly received different memos.

“As a Surface Warfare Officer, you'll command the most powerful warships on Earth — leading Sailors in combat operations across the world's oceans. From destroyers to aircraft carriers, you'll master ship handling, tactical decision-making, and leadership under pressure. SWO is the broadest warfare community in the Navy, preparing you for command at sea and executive leadership ashore.”
You are a Surface Warfare Officer, which means you drive ships and pretend you don't get seasick. Your 'tactical maritime operations' are standing watch on the bridge at 0300, staring at a radar screen, and praying that the contact bearing 270 is a fishing boat and not something with a targeting radar. You'll qualify as OOD, learn to conn the ship, and discover that the ocean is simultaneously beautiful and actively trying to kill you. Your chiefs run the ship. You manage the officers. The XO manages you. Nobody manages the sea state. Your knees will never forgive the ladders. Your sleep schedule will never forgive the watch bill. But the first time you're alone on the bridge at sunrise with nothing but ocean and the hum of the engines, you'll understand why sailors keep coming back.
“As a Submarine Warfare Officer, you'll lead the most survivable and lethal platform in the United States military — nuclear-powered submarines that operate beneath the ocean's surface for months at a time. You'll master nuclear engineering, tactical operations, and the art of undersea warfare. Submarine officers are among the most technically proficient leaders in any military, and their skills command premium salaries in nuclear energy, defense, and executive leadership.”
You are a Submarine Officer, which means you voluntarily chose to live inside a metal tube underwater for months at a time, and the Navy rewards this decision with a nuclear engineering education and the most exclusive culture in the military. Your 'submarine warfare' is weeks of boredom punctuated by moments of pure adrenaline when you're running from something or running toward something, and you can't tell your family about either. You'll qualify to run a nuclear reactor, navigate underwater without GPS, and sleep in a rack the size of a coffin. The nuke pipeline produces some of the most technically capable officers in any branch. The submarine culture produces some of the most insane inside jokes in human history. Both are earned.
The Real Life
Same dimensions, side by side. 1110 on the left, 1120 on the right.
Driving ships and leading sailors. As a Division Officer: standing OOD (Officer of the Deck) watches, managing a division of 15-50 sailors, and qualifying as a Surface Warfare Officer. As Department Head: leading 50-200+ sailors and managing one of the ship's major departments (Ops, Weapons, Engineering, Supply). The schedule is brutal at sea — expect 5 hours of sleep and 100+ hour work weeks during high-tempo operations.
Submarine operations — standing watch as Officer of the Deck, Engineering Officer of the Watch, or Diving Officer. Managing divisions of nuclear-trained enlisted sailors. The pace is intense and the responsibility is enormous from day one. You are standing watches and making decisions on a nuclear-powered submarine within months of reporting aboard.
Surface Warfare Officers School (SWOS) at Newport, RI is the initial training. The Basic Division Officer Course covers navigation, ship handling, combat systems, and engineering fundamentals. The real training happens during your Division Officer tours at sea, where you earn your SWO pin through rigorous qualification boards.
Nuclear Power School at Charleston (SC) is 6 months of intensive nuclear engineering academics. Prototype (NPTU) at Charleston or Ballston Spa (NY) adds 6 more months of hands-on reactor operation. Submarine Officer Basic Course (SOBC) at Groton (CT) adds 3 more months. Total pipeline: 15-18 months. The academic rigor is equivalent to a graduate engineering program compressed into one year.
Moderate. Bridge watch standing for extended periods, plus the physical demands of shipboard life. SWO School and SWOS curriculum are mentally rather than physically demanding.
Low to moderate. Submarine life is physically constrained (tight spaces, no exercise facilities on most boats). The mental and psychological demands far exceed the physical.
Surface Warfare Officer is the backbone of the Navy's officer corps, and it's as demanding as any job in the military. The recruiter will talk about commanding ships and leading sailors — both true and both genuine privileges. What they won't tell you: the lifestyle is brutal. Division Officer tours involve 100+ hour work weeks at sea, chronic sleep deprivation, and a qualification process designed to be exhausting. The SWO community has the highest attrition rate of any warfare community because many junior officers burn out and leave at the first opportunity. Those who stay and thrive find a career path that leads to commanding a warship — one of the most consequential leadership positions in the military. The civilian career transition is strong for leadership and management roles but requires deliberate skill-building in a technical or business domain. SWO develops leaders, but the cost is paid in years of missed sleep and personal sacrifice.
Submarine Warfare Officer is arguably the most intellectually demanding career path in the military. The recruiter will highlight the nuclear training, the leadership, and the prestige — all earned and all real. What they won't tell you: you will spend months underwater with no sunlight, no contact with family, and the knowledge that your decisions could have strategic nuclear consequences. The sleep deprivation is chronic and systematic. The nuclear pipeline is academically crushing — the attrition rate is real and there's no coasting. But the officers who complete a submarine tour emerge with credentials that the civilian world deeply respects. Fortune 500 companies, management consulting firms, and venture capital actively recruit submarine officers for their decision-making under pressure, technical depth, and leadership experience. The post-military earning potential is among the highest of any military career path ($120-200K+ within 2-3 years of transition). The cost is paid in years of personal sacrifice. Go in with eyes open.
