TG stands for Training Group (the group of Recruits that graduate on the same day). TG 01 is the training group that begins training the first week of October when the Navy fiscal year begins, meaning that most of the recruits in TG 01 arrive the last week of September. The smallest TG I've seen had 4 Divisions (11/23/2011) and the largest TG I've seen had 16 divisions (02/09/2018). The Drill Hall was built to accommodate up to 16 divisions. There could potentially be 52 TG's in a year since there are 52 weeks in a calendar year, but the RTC skips about 4 weeks each year. When a week is skipped, the next TG number is advanced to catch up with the week of the fiscal year either immediately or at some point soon after that so that there are times when consecutive TG's do not have consecutive numbers.
A division is approximately 88 recruits who live and train together. There can be as few as 55 to as many as 100 in a division. The division number is important and will help mail get to your recruit when included in the address and will help you find your new Sailor at PIR. Each division, except the 800's and 900's divisions (unless there are 2 of them in a TG), trains with a Brother Division. Brother Divisions are two consecutive divisions beginning with an odd number (001-002 for example). 800's divisions are the divisions for the special warfare candidates. 900’s divisions are the performance divisions. There are 3 types of 900 divisions. There are the Band/Bluejacket Choir/Drill team, otherwise known as Triple Threat (the musicians, singers, and drill team), the Sticks (those who carry the state flags), and the Ship Staff/Honor Guard (the body snatchers, those who guard various things...). (See 800 and 900 Divisions.) Division numbers begin at 001 each year for TG 01. Division 901 is the first 900 Division and is in TG 01. Division 801 is the first 800 division, but it may or may not be in TG 01. The division numbers continue with consecutive numbers until the next fiscal year.
When a group of new Recruits arrives at the RTC, they go through a simple sort - those with a Musician (MU) rating and those with music or flag/drill experience are assigned to a 900 division if those are needed. Those with contracts as candidates to Naval Special Warfare operator ratings are moved aside to be placed in the 800 division/s or for females to be placed together in a regular division. There are usually only 25 or fewer 800 divisions a year, so not every TG will have one, but some TG's will have one or two 800 divisions. (See 800 and 900 Divisions.) The remaining recruits are assigned pretty randomly, mostly as they arrive, to one to four additional divisions. When a large number of recruits arrive on the same day as happens during the summer months, that could change to a larger number of divisions that are started on the day of arrival, but seldom are more than four divisions filled on a particular day. In that case, recruits with similar ratings will end up in the same TG, but not necessarily in the same division. Once one division is full, they start filling another, so divisions often end up with groups of recruits from only a few areas. The Recruits' ratings do not influence which division they will be placed in except for those placed in an 800's or a 900's division.
Males are placed in either an integrated or all male division depending on the sort as they arrive. Females are placed in integrated divisions, containing both males and females. Division 317 in 2012 was an all female division, but that was a rare event up to that point and was to honor the W.A.V.E.S. Beginning in the summer of 2013, each TG was to have one all female division, which would be the sister division to an all male brother division, but the practice was discontinued so that it is now rare for there to be an all female division. 800 divisions are all male divisions since it would be rare for there to be enough female special ops candidates to fill a compartment. (See 800 and 900 Divisions.)
Sometimes a division fills and there are only a few recruits remaining from the arrival group; they are held as the first recruits for the next division; or there is a division that is not quite filled and they must wait until the next group of Recruits arrives to fill the division. When recruits have to wait for more recruits to arrive in the next week to fill the division, they may be in what is called a Push Division. Some of the Recruits in those divisions will be at the RTC for 7 1/2 weeks (8 Fridays) rather than the 8 1/2 weeks (9 Fridays) that most of the others in the TG and some in their division will be there. That is more likely to happen for those arriving on a Monday or Tuesday.
Sometimes there are Recruits who are unlucky enough to be held over and are placed in the TG for the next week rather than in the TG for the week they arrived in and are at the RTC 9 1/2 weeks (10 Fridays). That is more likely to happen for those arriving on Wednesday or Thursday or in the wee hours of Friday morning. That happens more in November and December when a large number of recruits ship early due to the Navy Recruiting Holiday Stand-down. It also happens when there is a week without a PIR or if storms cause recruits to arrive on a different day than the day they were sworn in. It also happens when a large number of recruits are shipped in the summer and early fall because of the need to ship recruits who signed up at the beginning of their Senior year of High School.
Those first 4-11 days after the new recruits arrive are called Processing Days (P-days). P-days can last up to 14 days for some recruits if they have to wait for additional recruits to arrive to fill a division. Although recruits are assigned to a ship and division upon arrival, they do not move to that ship until P-days are over and sometimes things will happen that will change a recruit's assignment or that will cause the division to be housed in a different ship; this is why it is possible that a recruiter might give you an address a day or two after your recruit arrived at the RTC indicating a particular ship and division and then when you get the form letter it is different. For this reason, we encourage you to wait on The Form Letter before sending letters.
The Ship number identifies the building their barracks are in. Each building also has a name of a famous US ship, but few refer to them by the name. It is the division number that is the most important and will help you to find your Sailor on the day of PIR, but the ship number is important when you send them letters because it helps to get the letters to them.
There are 14 different "ships" (barracks), and 12 or 16 divisions in each ship, and every one of them has a different address. Each of the 12 or 16 compartments within the ship can house up to 88 recruits and each ship can house up to 1,300 recruits. Each ship has its own galley, serving 3 nutritious meals a day for up to 1,300 recruits and staff members, as well as multiple classrooms. There are four sleeping compartments on each floor (deck) of the ship. The compartments are designated with a letter A through H (Alpha, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, and Hotel) plus either 01 or 02 after that--A-01, B-02, and F-01 for example. When there are integrated divisions (those with both males and females), the males of the 2 brother divisions share a compartment and the females of the 2 brother divisions bunk together across the hall from them. We seldom see more than 14 divisions within a ship at one time. The older ships appear to only contain 12 compartments. Sometimes a recruiter will give the ship name and/or a building number instead of or as well as a Ship number; you do not need to include the building number in the address, but you do need to include the Ship number. Only information in bold below--along with the division number--must be included when writing to your recruit.
Ship 01 (Bldg. 7122): USS Pearl Harbor (LSD-52) xxxx Kansas Street, Great Lakes, IL 60088-3122 (This is the barracks where your recruit will sleep during P-days. Your recruit will not receive mail in this ship.)

Ship 1 has separate compartments for males and females and is where your recruit will sleep and spend some time during P-days.
Ship 2 houses the 900 Divisions, which can be integrated (Triple Threat and Sticks/Flags) or all male (Ship Staff/Honor Guard) divisions. It contains all of the music practice rooms and instruments. Ship 2 has 16 compartments. Usually one 900 division per PIR group lives here, but occasionally a TG will have two 900 divisions and at least once there was no 900 division in a TG. Join 900's division sailors. (See 800 and 900 Divisions for more information.)
Ship 3 houses both integrated and all male divisions. Ship 3 has 16 compartments.
Ship 4 houses the 800 Divisions, which are all male divisions. It is used by recruits assigned as candidates to Naval Special Warfare operator ratings (SEALs or Special Operators, Navy Divers or ND, Special Boat Operators or SWCC, Aviation Rescue Swimmers or AIRR, and Explosive Ordnance or EOD). (See http://sofrep.com/10103/becoming-a-navy-seal-swcc/ and 800 and 900 Divisions for more information.) Regular divisions can also be housed on Ship 4 if the need arises and will have the nickname of Rifle Division to distinguish them from the Special Warfare Divisions. Ship 4 is also the RCU-Recruit Convalescent Unit-where sick or injured recruits go to heal and be cycled back into another TG. (See Recruit Convalescent Unit (RCU) and join RCU SHIP 04 DIV 2341 for more information.) The FIT Division is also located here. Recruits who have failed the official Physical Fitness Assessment (most often the swim or run) are sent here for intensive training in order to pass the test prior to having Battle Stations-21 (BST). (See Physical Fitness Assessment (PFA) and Fitness Improvement Training (FIT) and join fit program for more information.) When writing to a recruit in a FIT Division, use the above address for this Ship, but put "FIT Division- Male" or "FIT Division-Female" in place of the Division Number or use Ship 4 Div 2347 (for those who failed the run by less than a minute), or Ship 4 Div 2444 (for those who failed the run by more than a minute to less than two minutes), or Ship 4 Div 2247 (for those who failed the run by more than two minutes), or Ship 4 Div 2381 (for those who failed any part of the swim test). The FAST and PASS programs are also here. (See http://www.navy.mil/submit/display.asp?story_id=54872.)
Ship 5 is for those recruits in the process of being discharged from Boot Camp. It takes 2-3 weeks to be processed out once a recruit is moved to Ship 5 (SEPS). (Join Ship 5 Moms(Formerly Ship 17) and see FAQ about SEPS and http://www.bootcamp.navy.mil/faq.html#separations for more information.) When addressing letters, use the above address for this Ship, but put "SEPS Male" or "SEPS Female" in place of the Division Number. The address may also include a compartment number, B-02 for a male for example. Ship 5 is also for THU-Temporary Holding Unit-where recently graduated Sailors go if they are on hold for "A" school--those Sailors with a contract for Culinary Specialist (CS) often find themselves in the THU for one to four weeks after PIR. Those in the THU are in separate quarters from those being discharged. Few graduating Sailors are in THU since the change to Friday and Saturday Departures, but some will be sent here while awaiting clearance or to conduct a special physical or while waiting to class up if there is no housing available at the "A" School or for some other reason. Sailors who have passed Battle Stations-21 (BST) after being in FIT or in the RCU go to the THU before heading to "A" School or training with the next PIR group. (See http://www.bootcamp.navy.mil/faq.html#temp_holding.) Federal Health Care Center blood collections are also done on Ship 5 when recruits choose to donate blood while at the RTC. (See https://www.facebook.com/ASBPGreatLakes/, http://www.militaryblood.dod.mil/ViewContent.aspx?con_id_pk=230&fr=s and http://www.militaryblood.dod.mil/viewcontent.aspx?con_id_pk=813.)

Ship 6 houses both integrated and all male divisions and was previously the RCU. .
Ship 7 houses both integrated and all male divisions. Ship 7 was not used for recruits between the 08/17/2012 TG and March 2018. Recruits are now being housed here again.
Ship 9 houses both integrated and all male divisions. Ship_9_USS_John_F_Kennedy_The_Story_and_History.pdf Ship 9 is not currently being used for recruits. (No recruits have been housed in Ship 9 since the 10/03/2014 TG.)
Ship 10 houses both integrated and all male divisions. Ship 10 is not currently being used for recruits.
Ship 11 houses both integrated and all male divisions. Ship 11 has 16 compartments. Ship_11_USS_Kearsarge_The_Story_and_History.pdf

Ship 14 houses both integrated and all male divisions. Ship 14 has 16 compartments. Ship_14_USS_Arizona_The_Story_and_History.pdf
Ship 17 is used as the In-processing barracks for those in the NAVET/OSVET Program. Ship 17 was also used for THU and SEPS years ago.
Any ship that houses integrated divisions could be used to house an all female division when there is one.
Four other ships that are important for your recruit are the USS Marlinespike, the USS Chief, the USS Wisconsin, and the USS Trayer. The USS Marlinespike is where recruits learn basic seamanship, line-handling, shipboard watch and teamwork. The USS Chief is used to introduce a recruit to the concepts of shipboard damage control, firefighting, and chemical, biological, and radiological (CBR) defense. The USS Wisconsin is where recruits learn the basics of firearm handling with a 9mm pistol on the base's simulated firing range. The USS Trayer is used for Battle Stations-21 (BST). It is an award-winning destroyer mock up that uses special effects technology from the theme park industry to simulate shipboard emergencies as a capstone test of recruits' skills and teamwork.
Your recruit will spend some time during P-days on the USS Red Rover for medical and dental exams and procedures and receive his/her glasses if those are needed. (See http://www.lovell.fhcc.va.gov/locations/USSRedRover.asp.)
If your recruit becomes sick or injured, s/he may visit the USS Tranquillity. (See http://www.lovell.fhcc.va.gov/locations/USS_Tranquillity.asp.) The USS Tranquillity is a branch of the Captain James A. Lovell Federal Health Care Center (FHCC) and recruits may be taken there if needed.
If your recruit requires additional dental work, s/he will get that on board the USS Osborne. (See http://www.lovell.fhcc.va.gov/locations/USSOsborne.asp.)
This PowerPoint by Craig that will show you where everything is and will give you more information on the RTC. (Craig is retired Navy and runs NavyDEP.com and is also on this site.) Although you are not able to take any outside photos when you go to the RTC for PIR, the information at http://api.ning.com/files/o4XkbUTbkb-OCKgNSgkvT923buYRNRm51WgJ3qtIZPryijmbY3jC-rdq6POXq6EGek7nBYxLkX9h1d-LSbHa3aCHupDygd0Z/Aerial_View_of_Camp_John_Paul_Jones.pdf is within the public domain and is allowed to be posted._
Some may encourage you to change your Username to include your recruit's Ship and Division number while your Recruit is in BC, but be cautious with that if you choose to do so and do not do it if your recruit is in an 800 division. Check out OPSEC and PERSEC (Making Changes To Your Profile) for more on making this change and other changes you may want to make. Although including the Ship and Division number in your Username helps to find others in the same division, if the Chiefs and/or RDC's are checking out the site, this draws attention to the division number, so you may want to consider removing that from your Username once you have made contact with others with loved ones in the same division.
