The United States has five federal service academies, each tied to a specific branch of the military. But the full landscape of military-focused higher education is broader than that. When you include senior military colleges, military junior colleges, and state maritime academies, the number grows significantly depending on how you define “military academy.”
The Five Federal Service Academies
These are the institutions most people picture when they hear “military academy.” Each one is a four-year undergraduate college fully funded by the federal government, meaning cadets and midshipmen pay no tuition and have room and board covered. In return, graduates owe a mandatory service commitment as commissioned officers in their respective branch.
- U.S. Military Academy (West Point) trains officers for the Army.
- U.S. Naval Academy (Annapolis) trains officers for the Navy and Marine Corps.
- U.S. Air Force Academy (Colorado Springs) trains officers for the Air Force and Space Force.
- U.S. Coast Guard Academy (New London) trains officers for the Coast Guard.
- U.S. Merchant Marine Academy (Kings Point) trains officers for the Merchant Marine, with many graduates also serving in the armed forces.
At West Point, for example, graduates commit to a minimum of five years on active duty in the Army plus three additional years in a reserve component. Cadets may leave before the start of their junior year without owing any service obligation, but once they take their oath at that point, the commitment is binding. The other academies follow similar structures, though the exact length of active duty varies by branch.
Admission to any of the five academies is highly competitive. Four of them (West Point, Annapolis, Air Force, and Merchant Marine) require a congressional nomination, typically from a U.S. senator or representative. The Coast Guard Academy is the exception: it admits students based solely on a competitive application process with no nomination required.
Six Senior Military Colleges
Beyond the federal academies, there are six senior military colleges (SMCs) recognized by the federal government. These are traditional four-year universities that blend civilian higher education with structured military training. Unlike the federal academies, SMCs are not tuition-free, though financial aid and ROTC scholarships are available.
- Texas A&M University (Corps of Cadets)
- Norwich University
- Virginia Military Institute
- The Citadel
- Virginia Tech (Corps of Cadets)
- University of North Georgia
Every cadet at an SMC participates in the Reserve Officers’ Training Corps (ROTC) program. However, only those who receive an ROTC scholarship are required to enter military service after graduation. Graduates who do commission through Army ROTC can compete for active duty, Army Reserve, or Army National Guard assignments. Some SMCs, like Virginia Military Institute and The Citadel, require all students to live in a barracks-style environment throughout their time on campus, while others like Texas A&M and Virginia Tech have a corps of cadets that operates alongside a larger civilian student body.
Six State Maritime Academies
The six state maritime academies operate as colleges within state university systems, running four-year undergraduate programs focused on merchant marine operations, marine engineering, and maritime transportation. They provide the instruction, theory, and at-sea training needed to earn a U.S. Coast Guard license as a Merchant Mariner and to become a commissioned officer.
- California State University Maritime Academy (Cal Maritime)
- Great Lakes Maritime Academy
- Maine Maritime Academy
- Massachusetts Maritime Academy
- SUNY Maritime College
- Texas A&M Maritime Academy
The Maritime Administration (MARAD), a federal agency within the Department of Transportation, provides limited federal assistance and public training ships to these six schools through formal agreements. While state maritime academies are distinct from the federal Merchant Marine Academy at Kings Point, they play a parallel role in training officers for both the U.S. Merchant Marine and the armed forces. Many graduates go on to serve in the Navy, Coast Guard, or other branches alongside their civilian maritime careers.
How the Total Adds Up
If you count only the federal service academies, the answer is five. Add in the six senior military colleges and six state maritime academies, and you reach 17 institutions with a formal military education mission recognized at the federal level. There are also several military junior colleges that offer two-year programs with early commissioning pathways, plus dozens of private military preparatory schools at the high school level that have no direct commissioning authority but prepare students for academy or ROTC admission.
The right number depends on what you mean by “military academy.” For most people asking the question, the five federal service academies are the core answer. They are the only schools where the federal government fully funds your education in exchange for a guaranteed service commitment as a military officer. The senior military colleges, state maritime academies, and junior colleges expand the picture for students who want a military-oriented education with more flexibility in whether they ultimately serve.
