What It Really Takes to Become a Navy SEAL
How to become a Navy SEAL is one of the most searched military career questions — and for good reason. The path is long, brutal, and deeply selective. Here is the short answer:
To become a Navy SEAL, you must:
- Meet basic eligibility — U.S. citizen, age 18–28, high school diploma, clean record
- Score high enough on the ASVAB — line score of GS+MC+EI ≥ 170 or VE+MK+MC+CS ≥ 220
- Pass the Physical Screening Test (PST) — swim, push-ups, sit-ups, pull-ups, and a run
- Enlist in the Navy — ideally with a SEAL Challenge Contract before boot camp
- Complete BUD/S Prep — an 8-week conditioning course before the main pipeline
- Survive BUD/S — a 24-week program including the infamous Hell Week
- Finish Parachute Jump School — 3 weeks of airborne training
- Graduate SEAL Qualification Training (SQT) — 26 weeks of advanced skills training
- Earn the Trident — and receive your first SEAL Team assignment
The full pipeline takes over a year from boot camp to Trident. Only about 9.5% of those who start the process make it all the way through.
This guide covers every step in detail — requirements, training phases, attrition rates, and what separates candidates who finish from those who don't.

Basic Requirements: How To Become a Navy SEAL
Before we even discuss the physical and mental torture of BUD/S, we must look at the administrative gatekeepers. The Navy has set strict baseline criteria to ensure that only those with the proper foundation are allowed to attempt the selection process.
If you do not meet the baseline Navy SEAL Requirements, your journey ends before it even begins. We encourage everyone to review these standards honestly before walking into a recruiting office.
Age, Citizenship, and Education Standards
First, let's talk about the absolute baselines. To apply for the SEAL pipeline, you must be a citizen of the United States. If you hold dual citizenship, you may be required to renounce your non-U.S. citizenship to obtain the necessary security clearances.
Age limits are strict. Candidates must be between 17 and 28 years old (17-year-olds require parental consent). While the Navy historically capped the age at 28, waivers are occasionally available on a case-by-case basis for exceptional candidates aged 29 or 30. For prior-service SEALs seeking officer roles, the age limit can sometimes be waived up to 33.
Educationally, you must possess a high school diploma or an equivalent credential. Furthermore, your moral character must be pristine. This means no history of felony convictions, drug abuse, or significant legal issues. While minor traffic infractions won't disqualify you, any pending lawsuits or serious criminal records will halt your application immediately.
ASVAB Scores and Vision Requirements
The physical demands of a Special Warfare Operator are immense, but the cognitive demands are just as high. The Navy uses the Armed Services Vocational Aptitude Battery (ASVAB) to ensure you have the mental capacity to handle complex communications equipment, dive physics, and tactical planning.
To qualify under the Navy SEAL Physical Requirements, you must achieve one of the following ASVAB line score combinations:
- GS + MC + EI ≥ 170
- VE + MK + MC + CS ≥ 220 (with VE + AR ≥ 110 and MC ≥ 50)
No waivers are granted for these ASVAB line scores. Additionally, while the Navy requires a minimum Armed Forces Qualification Test (AFQT) percentile score of 35 for general enlistment, historical data shows that men who succeed at BUD/S typically score a 78 or better on the AFQT.
Your eyes must also meet strict standards. Your uncorrected vision must be at least 20/40 in your best eye and 20/70 in your worst eye, and both eyes must be correctable to 20/25. Color blindness is an absolute disqualifier because operators must be able to distinguish colored smoke, wire insulation, and navigation lights under extreme stress.
The Physical Screening Test (PST): Minimum vs. Competitive Standards
To secure an invitation to SEAL training, you must pass the Physical Screening Test (PST). The PST is administered by a Special Warfare mentor or coordinator. It tests your muscular endurance, cardiovascular capacity, and water competency.
There is a massive difference between "minimum" passing scores and "competitive" scores. If you only train to meet the minimum standards, you are statistically setting yourself up to quit. The Navy uses a nationwide "draft" system where candidates compete against each other based on their PST performance. Those with competitive scores are selected first.
| PST Event | Minimum Standard | Competitive Standard |
|---|---|---|
| 500-Yard Swim (Breaststroke or Combat Swimmer Stroke) | 12:30 | 9:30 or faster |
| Push-ups (2-minute limit) | 50 | 80–100+ |
| Sit-ups (2-minute limit) | 50 | 80–100+ |
| Pull-ups (No time limit, dead hang) | 6 | 15–25 |
| 1.5-Mile Run (Timed, in running shoes) | 10:30 | 9:30 or faster |
Your PST scores are only valid for six months. If you do not ship to boot camp within that window, you will have to re-test.
The Navy SEAL Training Pipeline Timeline
The journey from a civilian civilian to a Trident-wearing Special Warfare Operator is a long, multi-stage marathon. It is designed to systematically break down your ego and rebuild you as a highly disciplined, team-oriented operator.
If you want to know How to Become a Navy SEAL, you must understand that the training timeline is not just BUD/S; it is a year-long gauntlet of continuous evaluation.
Step-by-Step Guide on How To Become a Navy SEAL
Your journey begins at a local recruiting office. We highly recommend that you secure a SEAL Challenge Contract (the Special Operator, or SO, rating) before you enlist. This contract guarantees you a spot in the training pipeline, provided you maintain your physical readiness.
Once you sign your enlistment contract, you enter the Delayed Entry Program (DEP). During this time, you will work directly with an assigned Special Warfare Mentor. These mentors are typically retired or active-duty SEALs or SWCC operators who will push you to reach competitive PST scores.
From DEP, you will ship to Navy Recruit Training Command (boot camp) in Great Lakes, Illinois. During your eight weeks of boot camp, you will undergo standard sailor training while participating in advanced weekly physical workouts designed specifically for Spec Ops candidates.
BUD/S Prep, Orientation, and the Three Phases
After boot camp graduation, you will transition to the Naval Special Warfare Preparatory School (BUD/S Prep) in Great Lakes. This is an 8-week physical conditioning course designed to prepare your body for the sand and surf of Coronado. At the end of Prep, you must pass a Modified PST, which includes:
- 70 push-ups
- A 4-mile run in 31 minutes
- A 1,000-meter fin swim in 20 minutes
If you pass, you finally pack your bags for the Naval Special Warfare Center in Coronado, California. Here, you will begin the core of your Navy SEAL BUD/S Training:
- BUD/S Orientation (3 weeks): This phase introduces you to the physical standards, obstacle course, and instructors. It is designed to weed out those who are not physically or mentally prepared for the daily grind.
- Phase 1: Physical Conditioning (7 weeks): This phase tests your physical limits, water competency, and teamwork. It culminates in the legendary Hell Week, a 5.5-day test of pure mental endurance.
- Phase 2: Combat Diving (7 weeks): This phase focuses on underwater competency, open and closed-circuit SCUBA diving, and pool competency. You will learn to perform under extreme underwater stress, simulating equipment failures and combative situations.
- Phase 3: Land Warfare (7 weeks): This phase moves you to San Clemente Island, where you will learn basic weapons handling, demolitions, land navigation, and small unit tactics.
Post-BUD/S: Parachute Jump School and SEAL Qualification Training (SQT)
Graduating from BUD/S is a massive achievement, but you are still not a Navy SEAL. You are designated as a Special Warfare Operator candidate.
Next, you will attend the 3-week Military Freefall/Static Line Parachute Jump School. Here, you will learn basic airborne insertion techniques, canopy control, and emergency procedures.
Following jump school, you enter SEAL Qualification Training (SQT), a grueling 26-week program. SQT takes the basic skills you learned in BUD/S and elevates them to combat-ready standards. You will undergo advanced weapons training, close quarters combat (CQC), tactical medicine, maritime operations, and Survival, Evasion, Resistance, and Escape (SERE) training.
Only after successfully graduating from SQT will you receive your Navy Special Warfare rating (SO), be awarded the coveted Navy SEAL Trident, and be assigned to an active SEAL Team.
Career Progression: How To Become a Navy SEAL Officer
For those who wish to lead these elite operators, the pathway is slightly different and even more competitive. There are roughly ten times more enlisted SEALs than officers, meaning officer slots are highly guarded.
Prospective officers can apply through the U.S. Naval Academy (USNA), Navy ROTC programs, Officer Candidate School (OCS), or via lateral transfer from other Navy communities. The USNA typically receives 20 to 30 slots per year, while ROTC receives 15 to 25. The acceptance rate for OCS candidates is roughly 1 in 8.
All officer candidates must attend the SEAL Officer Assessment and Selection (SOAS) course during the summer of their junior or senior year. SOAS is a multi-week physical and leadership evaluation.
The SEAL Officer Selection panel meets annually in September to select candidates who will begin BUD/S training during the subsequent fiscal year.
Surviving the Pipeline: Attrition, Mental Toughness, and Diversity
The physical training at BUD/S is designed to push human physiology to its absolute limit. However, physical strength alone is merely the price of admission. The real battle is fought entirely between your ears.
Attrition Rates and the Brutal Reality of Hell Week
The statistics are sobering. Only about 9.5% of those who sign up for Navy SEAL training make it all the way through the pipeline. The overall BUD/S attrition rate sits between 68% and 75%, with Phase 1 alone eliminating the vast majority of candidates.
The ultimate filter is Hell Week, which occurs in the fourth week of Phase 1. During this 5.5-day event, candidates run over 200 miles, perform continuous physical training for over 20 hours a day, and receive a maximum of 4 hours of sleep total across the entire week.
Hell Week alone eliminates more than 75% of those who enter Phase 1. Most candidates choose to "Drop On Request" (DOR). To quit, a candidate must perform the legendary ritual: ring the brass bell three times, place their green helmet liner on the deck, and walk away. We detail this mental battle extensively in our guide on Hell Week for Navy SEALs.
Mental Fortitude: The Four Pillars of Resilience
Those who survive the Navy SEAL Training Journey Challenges rely on psychological tools to manage stress. The Navy actively teaches the "Four Pillars of Resilience" to help candidates cope with the overwhelming environment:
- Goal Setting (Micro-Goals): Successful candidates do not think about surviving the next six months, or even the next week. They focus on surviving the next hour, the next meal, or the next step.
- Mental Rehearsal (Visualization): Candidates mentally practice complex events — like pool competency or obstacle courses — before executing them, priming their nervous systems for success.
- Self-Talk: Replacing negative thoughts ("I am freezing and my chest hurts") with positive, active scripts ("I can take one more step") keeps the panic response at bay.
- Arousal Control: Using deep-breathing techniques (like 4x4 box breathing) to lower the heart rate and calm the nervous system under extreme stress.
Additionally, candidates undergo the C-SORT (Computerized Special Operations Resiliency Test), which evaluates their psychological resilience and personality traits on a 1-to-4 band scale. Your C-SORT score is combined with your PST run and swim times to determine your contract eligibility.
Women and Prior Service Members in SEAL Selection
Since late 2015, all combat roles in the United States military, including Navy SEALs, have been open to women. The standards for female candidates are identical to those for male candidates; there are no modified physical requirements.
Historically, the first woman to enter the SEAL training pipeline dropped out during the 3-week Indoctrination phase in August 2017. As of 2021, no woman has successfully finished the SEAL training pipeline, though a female sailor successfully completed the Special Warfare Combatant-Craft Crewman (SWCC) pipeline in July 2021.
For prior-service members or active-duty sailors in other ratings, the path involves converting their rating to Special Operator (SO). Under MILPERSMAN 1220-300, active-duty sailors must submit a rating conversion package through the Career Waypoints Program, undergo a diving medical exam, pass the PST, and complete a hyperbaric pressure test.
Life After Earning the Trident: SEAL Teams and Deployments
Earning the Trident is not the end of your training; it is simply the beginning of your career as a professional operator. Once assigned to a SEAL Team (Teams 1, 3, 5, 7, and 17 on the West Coast in Coronado; Teams 2, 4, 8, 10, and 18 on the East Coast in Little Creek, Virginia), you will enter a continuous training cycle.
A standard SEAL Team deployment cycle lasts roughly 18 to 24 months and is divided into three distinct phases:
- Individual Specialty Training (6 months): Operators attend specialized schools to learn sniper tactics, advanced communications, medical skills, or breaching.
- Unit Level Training (6 months): The entire SEAL platoon trains together, practicing small unit tactics, maritime boarding, and air operations.
- Task Group Level Training (6 months): The platoon integrates with other joint military assets to conduct large-scale, simulated missions.
This cycle culminates in a 6-month deployment to various theaters of operation worldwide.

As you promote, your responsibilities and compensation will adjust according to standard Navy SEAL Ranks and special duty pays.
Frequently Asked Questions About Becoming a Navy SEAL
What is the attrition rate for BUD/S training?
The overall BUD/S attrition rate sits between 68% and 75%. However, when looking at the entire pipeline from the moment a civilian signs an enlistment contract to the moment they graduate SQT, the success rate is only about 9.5%.
Statistically, of those who sign an enlistment contract, only 79% sign an enlistment contract, 45% graduate recruit training, 35% complete SEAL indoctrination, and just 10% complete BUD/S. Hell Week in Phase 1 is the single largest point of failure, eliminating more than 75% of candidates.
Can women attend BUD/S and become Navy SEALs?
Yes. Since December 2015, women have been fully eligible to volunteer for Navy SEAL training. They must meet the exact same physical, mental, and administrative standards as male candidates. While several women have attempted the selection process, as of 2021, no female candidate has successfully completed the SEAL pipeline.
What is the age limit to become a Navy SEAL?
The standard age limit to enlist and become a Navy SEAL is 18 to 28 years old. Seventeen-year-olds may apply with parental permission. The Navy does offer age waivers on a highly selective, case-by-case basis for exceptional candidates who are 29 or 30 years old, provided they possess outstanding PST scores and clean background records.
Conclusion
Becoming a Navy SEAL is one of the most physically demanding and mentally exhausting achievements a human being can pursue. The path is guarded by high standards, brutal training environments, and a selection process designed to make you quit.
Yet, for the 9.5% who refuse to ring the bell, the reward is entry into one of the most elite brotherhoods on earth. They live by the words of the Navy SEAL Ethos: "I will never quit. I persevere and thrive on adversity. My Nation expects me to be physically harder and mentally stronger than my enemies."
