How Long Is Boot Camp for Each Branch?

If you're counting down to basic training, one of the first things you want to know is simple: how long is this going to last? The answer depends on your branch, and the range is wider than most people expect, from about seven and a half weeks to a full thirteen. Here's the length of boot camp for every branch in 2026, plus a couple of things the published numbers leave out.

Boot Camp Length by Branch

These figures reflect current 2026 lengths reported across recruiting resources, and they've been stable for a while. A couple of notes: the Navy lengthened its boot camp in recent years, so confirm the exact current length with your recruiter, and the Army figure is for standard Basic Combat Training (see the OSUT note below for combat jobs).

Why the Lengths Differ

The differences aren't random, they reflect what each branch needs its new members to be ready for.

• The Marine Corps is the longest because it puts every recruit through an intense transformation focused on the warrior ethos and combat readiness, capped by the Crucible, a grueling 54-hour final event. Every Marine is expected to be a rifleman first.
• The Army sits in the middle, teaching soldiering fundamentals to a huge and varied force.
• The Navy and Coast Guard focus on shipboard life, water survival, and the specific demands of maritime service.
• The Air Force and Space Force are the shortest because their model leans more heavily on the extensive technical training that follows basic. The initial transformation is shorter; the job schooling is often long.

What the Weeks Don't Count

The published length is the training itself, but there's more to the calendar:

• In-processing (or "zero week"). Before training officially begins, there's a reception period of several days to about a week for paperwork, gear issue, medical checks, and haircuts. It usually isn't counted in the boot camp length.
• Job training after boot camp. For most recruits, basic is only step one. After graduation you move on to job training (called AIT in the Army, A-School in the Navy and Coast Guard, or tech school in the Air Force), which can run from a few weeks to many months depending on your job.
• Army OSUT. For Army combat arms jobs (like infantry or armor), basic and job training are combined into One Station Unit Training, a single course of roughly 14 to 22 weeks. Infantry OSUT is on the longer end.

Your Real Time Away From Home

Add it all up and the honest picture is this: boot camp itself is measured in weeks, but your total time away from home before you reach your first real assignment is usually measured in months, once you include in-processing, graduation, and the job training that follows. Plan for that when you and your family think about the transition. To know what those weeks feel like day to day, read what boot camp is really like, and use the time before you ship to get in shape and work through our 30-day checklist.

Bottom Line

Boot camp length ranges from about 7.5 weeks (Air Force and Space Force) to 13 weeks (Marine Corps), with the Army, Navy, and Coast Guard in between. But the number on paper is just the training phase. Between in-processing on the front end and job training on the back end, expect to be away from home for months, not weeks, before you settle into your first assignment.

The most useful next step: if you're still weighing branches, factor in more than boot camp length, culture, jobs, and lifestyle matter far more over a career. Our Branch Quiz is a good place to start.
