The U.S. Navy currently operates boot camp at Recruit Training Command Great Lakes, located at Naval Station Great Lakes, near North Chicago, Illinois. Instead of having Drill Sergeants or Drill Instructors like other branches of the U.S. Armed Forces, the U.S. Navy has RDCs (Recruit Division Commanders) that are assigned to each division. Training lasts approximately eight weeks (although some recruits will spend as many as nine weeks in training due to the somewhat complicated processing cycle). Days are counted by a system that lists the week and day that they are on, for example 7-3 for week 7 day 3. The first approximate week is counted P-1, P-2, etc. which denotes that it is a processing day and does not count as part of their 8-week training period. Recruits are instructed on military drill, basic seamanship, basic shipboard damage control, firefighting, familiarization with the M9 pistol and Mossberg 500 shotgun (the Navy no longer gives instruction on the M-16 in boot camp), pass the confidence chamber (tear gas filled chamber), PT, and the basic essentials on Navy life. Recruits also attend many classes throughout boot camp on subjects such as Equal Opportunity, Sexual Assault Victim Intervention, Uniform Code Of Military Justice, recognition of naval aircraft and vessels, and more. In order for recruits to pass boot camp, they will be physically and mentally tested on a 12-hour exercise called Battle Stations which consists of 12 different scenarios consisting of firefighting, first aid knowledge, survival at sea, mass casualties, shipboard flood control, bomb detection and many other skills that they have been learning in the past 7 weeks. After completion of boot camp, freshly minted Sailors are sent either to various "A" Schools located across the United States, where they begin training to receive their ratings (jobs) or to apprenticeship training, where they then enter the fleet without a designation.
The Navy formerly operated Recruit Training Centers in San Diego, California; Orlando, Florida; Meridian, Mississippi; and Port Deposit (Bainbridge), Maryland. From 1942 to 1946 the Navy had two additional training sites. Naval Training Station (USNTS Sampson) (in 1950 renamed Sampson Air Force Base) near Seneca Lake, NY trained over 400,000 recruits. as well as Farragut Naval Training Station in Bayview, Idaho.
