What is Navy SEAL BUD/S Training?
BUD/S stands for Basic Underwater Demolition/SEAL training, a program that serves as the primary selection and training pipeline for the Navy SEALs. This demanding training is approximately six months long and pushes candidates to their absolute physical and mental limits. The core purpose is to identify individuals who possess the character, grit, and teamwork skills required for special operations.
The entire course is conducted at the Naval Special Warfare Center in Coronado, located in San Diego, California. Here, SEAL candidates are subjected to constant physical challenges, organized chaos, sleep deprivation, and extreme stress. Only those with unbreakable determination will successfully complete the training and move on to the next stage of becoming a Navy SEAL.
The Pathway to Coronado
Before a candidate ever sets foot on the Grinder in San Diego, they must complete a series of preliminary steps. The process begins with Navy recruit training, also known as boot camp, at Recruit Training Command at Naval Station Great Lakes. Following boot camp, aspiring SEALs attend the Naval Special Warfare Preparatory School, often called BUD/S Prep, also located at Naval Station Great.
This eight-week prep school is a challenging training program designed to prepare candidates for the rigors ahead. The curriculum at BUD/S Prep focuses on improving physical fitness to meet and exceed the demanding standards of BUD/S. Candidates work on swimming, running, and calisthenics, all of which are measured by the Physical Screening Test (PST).
The training command works to physically and mentally prepare candidates for the shock of BUD/S. This phase helps weed out individuals who may not be ready, giving them a taste of the commitment required. Success here is a strong indicator of a candidate's potential to succeed in Coronado.
The Physical Screening Test (PST)
The PST is the entry ticket to BUD/S, and candidates must pass it to even be considered for the program. The test consists of five events with a specific time limit for some, measuring a candidate's physical readiness. While there are official minimum standards, prospective candidates are encouraged to aim for much higher, competitive scores.
The events are a 500-yard swim, push-ups, sit-ups, pull-ups, and a 1.5-mile run. A strong performance on the physical screening is non-negotiable. Many potential candidates use a PST calculator online to track their progress and see how their PST scores stack up against those of successful SEAL candidates.
Below is a table showing the minimum standards versus the recommended competitive scores for the Physical Screening Test.
| Event | Minimum Standard | Competitive Score |
|---|---|---|
| 500-yard swim | 12 minutes, 30 seconds | Under 9 minutes |
| Push-ups (2 min) | 50 | 80-100+ |
| Sit-ups (2 min) | 50 | 80-100+ |
| Pull-ups | 10 | 15-20+ |
| 1.5-mile run | 10 minutes, 30 seconds | Under 9 minutes, 30 seconds |
The Three Phases of BUD/S
BUD/S is broken down into three distinct phases, each focusing on a different aspect of special warfare. The entire BUD/S training curriculum is about 24 weeks long. Each BUD/S phase builds upon the last, progressively increasing in difficulty and complexity.
First Phase: Basic Conditioning
The first phase, the basic conditioning phase, lasts seven weeks and is dedicated to extreme physical conditioning and building mental tenacity. Days begin before sunrise with hours of intense physical training. SEAL candidates run for miles in the soft sand, swim long distances in the cold Pacific Ocean, and perform endless calisthenics.
This conditioning phase includes weekly four-mile timed runs, a timed obstacle course, and two-mile timed swims in the ocean. The instructors are relentless, pushing the class to work as a team under immense pressure. It is here that many candidates realize they do not have what it takes to continue.
The defining event of this phase, and of all BUD/S, is Hell Week. It begins on a Sunday during the fourth week and concludes on Friday, consisting of a grueling five-and-a-half days of continuous training. Candidates operate on less than four hours of sleep for the entire week while facing non-stop physical tasks, cold water immersion, and mental games from the instructors.

Second Phase: Diving
The seven-week second phase is the combat diving phase. Those who survive the first phase are introduced to the underwater world, a critical operational environment for Navy SEALs. This phase focuses on teaching combat diving and underwater operations.
Candidates become proficient in both open-circuit (SCUBA) and closed-circuit (rebreather) diving. The training is physically and mentally taxing, as it requires comfort in a dangerous and unforgiving environment. Students learn to handle emergencies, such as having their air supply cut off, while remaining calm and focused many feet below the surface.
Third Phase: Land Warfare
The final seven weeks of training BUD/S are dedicated to land warfare. This phase takes the candidates' individual and team skills to the next level. They receive instruction in weapons handling, demolitions, small-unit tactics, patrolling, and rappelling.
A crucial and often overlooked part of land warfare training is learning to conduct hydrographic survey operations. This involves mapping coastal regions, charting beach topography, and identifying landing zone obstacles, which is vital for amphibious special operations. These hydrographic survey skills allow a SEAL team to approach and operate in enemy territory with precision.
The phase and all of BUD/S culminates in a final field training exercise on San Clemente Island. Here, candidates must apply all the skills they've learned throughout the past several months in a series of simulated operational missions. It is the last major hurdle before a class graduates from Basic Underwater Demolition/SEAL BUD/S training.
Mental Toughness is Everything
While superb physical readiness is a prerequisite, mental tenacity is what truly separates those who graduate from those who quit. Candidates are under constant stress, sleep-deprived, and pushed past their perceived limits every single day. The ability to endure pain and exhaustion is paramount.
Instructors employ psychological tactics to break the candidates' will. They may force a boat crew to carry a heavy inflatable boat on their heads for hours or make them sit in the cold surf zone. The objective is to identify individuals who lack the mental fortitude to function in high-stakes special operations.
The Importance of Teamwork
BUD/S is not a place for individual glory. Teamwork is embedded in every aspect of the training, from log PT to boat crew drills. Many of the evolutions are impossible to complete alone, forcing candidates to rely on one another to succeed.
Instructors constantly evaluate a candidate's ability to be a good teammate. A selfish attitude or failure to support the team can lead to being dropped from the course. The intense, shared hardship forges powerful bonds among the candidates, often lasting a lifetime.
The Infamous Bell
A simple brass bell sits in the center of the BUD/S compound. This bell offers the quickest escape from the demanding training. A candidate only needs to approach it and ring it three times to quit.
The bell serves as a constant, physical reminder that an end to the suffering is just a few steps away. It tempts candidates during their weakest moments, whether shivering from the cold or collapsing from exhaustion. For those who succeed, the decision not to ring it is more powerful than any physical feat they accomplish.
Attrition Rate
The high attrition rate of BUD/S is by design. The Naval Special Warfare Center seeks to find the select few who are suitable for the immense pressures of being a Navy SEAL. As a result, typically 70-80% of candidates who begin BUD/S will not graduate.
Some classes have seen even higher dropout numbers, reinforcing the program's reputation as the world's most difficult military training. This extreme filter ensures that only the most dedicated and resilient operators join a SEAL team. This is a fundamental aspect of the SEAL history and legacy.
Beyond BUD/S
Graduating from BUD/S is an incredible achievement, but it does not mark the end of a candidate's training pipeline. Graduates then proceed to SEAL Qualification Training (SQT), another rigorous, multi-month course. SQT focuses on advanced tactical skills, including marksmanship, close-quarters combat, and mission planning.
After successfully completing SQT, these warriors finally earn the right to wear the coveted Navy SEAL Trident. This insignia signifies their official entry into the special warfare community. They are then assigned to a SEAL Team to begin their careers as members of one of the world's most elite fighting forces, where their training continues to evolve.
Why Is The Training So Difficult?
The reason for such a difficult training program is directly related to the missions that Navy SEALs are tasked with. They operate in the most severe environments on Earth, from arid deserts to the freezing arctic. Their missions demand a level of physical and mental resilience that far exceeds that of a conventional soldier.
The intense stress of BUD/S simulates the chaos and pressure of actual combat. This challenging training weeds out individuals who might falter when lives are on the line. Only those with an absolute and unwavering commitment to the mission and their teammates will make it through.
The SEAL Ethos
BUD/S does more than just train the body; it instills the core values of the Naval Special Warfare community. These values include integrity, discipline, teamwork, and a profound refusal to quit. Candidates learn that the mission and their teammates always come before themselves.
This mindset is captured in the SEAL Creed, which every member embodies. It reads, in part: "I will never quit... My Nation expects me to be physically harder and mentally stronger than my enemies. If knocked down, I will get back up, every time. I will draw on every remaining ounce of strength to protect my teammates and to accomplish our mission. I am never out of the fight."
Conclusion
Navy SEAL BUD/S training is a crucible designed to forge ordinary men, both enlisted sailors and the occasional SEAL officer, into extraordinary warriors. It relentlessly tests the physical and mental limits of every candidate who attempts it. The trials of BUD/S ensure that only the most resilient and dedicated individuals earn the right to call themselves Navy SEALs.
Although the training is unbelievably tough, it has a clear and vital purpose. It prepares SEALs for the immense challenges they will encounter in real-world special operations. The skills, mindset, and mental tenacity developed during BUD/S are what allow them to succeed on the battlefield and return home safely.
For the select few who have what it takes to graduate, BUD/S is the foundational step on their journey into an elite brotherhood. It is a testament to what is possible when human beings refuse to give up. The training defines the very essence of a Navy SEAL.
