We got an inside look at how the United States Navy trains sailors to work on Submarines during its eight-week course at the Basic Enlisted Submarine School at Naval Submarine Base New London, Groton, CT. Students train to combat worst-case onboard scenarios such as flooding and fires in realistic simulators. They also learn the techniques they must employ if they have to escape from a submarine and ascend to the ocean surface inside a trainer known as the Pressurized Submarine Escape Trainer or PSET. Volunteers for submarine duty go through a mental health screening, and according to the Navy, can be disqualified if they are diagnosed with depression or anxiety disorders - medical issues that don't necessarily disqualify applicants from other roles in the US military. INSIDER spent 6 days inside the Submarine School to observe different classes of students at various stages of training. 0:00: Intro 0:26: Training overview 1:36: Enlisting & requirements 3:23: Inside a submarine 4:11: Damage control simulator 8:39: Submarine force mission 9:39: Fire fighting simulator 13:34: Pressurized submarine escape trainer 20:42 Graduation MORE BOOT CAMP VIDEOS: How Army Medics Are Trained To Save Lives In Combat | Boot Camp | Insider Business https://www.youtube.com/watch?v=C0AGQTnSkhs How US Snipers, Tankers, Navy Sailors And More Are Trained | Boot Camp | Insider Business https://www.youtube.com/watch?v=Adi5F2BwasM Why The Army Is Changing How Drill Sergeants Are Trained | Boot Camp | Business Insider https://www.youtube.com/watch?v=bCgkyMXp3Nw ------------------------------------------------------ #USNavy #BootCamp #InsiderBusiness Business Insider tells you all you need to know about business, finance, tech, retail, and more.
