7. Maintain records of the overall performance of each  ship. When awarding final grades for performance, type commanders have broad authority. They may weigh separate  exercises  and  other  performances  to  evaluate the  ship’s  organization,  discipline,  and  opportunities  for training. They may delegate their authority for fleet training   (except   policy   guidance)   to   subordinate commanders   of   units   that   operate   outside   their supervision  and  observation. A training exercise must  be observed and analyzed if  it  is  to  be  effective.  If  it  will  be  graded,  formal observation is mandatory. Observers will come from outside the observed ship if an exercise is important enough.  Observers  should  analyze  and  critique  the exercise as soon as practical after observing it. The critique  should  identify  errors  and  deficiencies  in material   or   procedures,   and   it   should   include recommendations    for  improvement. A critique of a training exercise is based upon the ship’s readiness to deal with the situation simulated in the  exercise.  However,  the  observers  will  consider factors  over  which  the  ship  has  no  control.  The observing  command  submits  a  recommended  grade with a report of the exercises observed. However, the type commander or a designated subordinate awards a final grade that is planned to establish  uniformity within the  type.  An  evaluation  of  readiness  includes  the performance  of  basic  exercises  and  handling  of  actual casualties. SHAKEDOWN  AND  REFRESHER TRAINING A ship will undergo shakedown training if it was recently  commissioned.  A  ship  will  undergo  refresher training  if  it  was  recently  activated  or  is  leaving  a shipyard after a regular overhaul. In either case, a designated  Fleet  Training  Group  (FTG)  under  the direction   of   the  Commander,  Training  Command,  U.S. Atlantic  or  Pacific  Fleet,  will  put  the  ship  through intensive combat-readiness training. During that time, the  Commander,  Fleet  Training  Group,  has  operational control  of  the  ship. Fleet Training Group The primary purpose of an FTG is to help ships train themselves. To do that, FTGs have delegated authority to control the assignment of operating areas, coordinate and regulate training exercises, and supply training services in their assigned operating areas. An  FTG  is  generally  divided  into  an  administrative section  and  an  afloat  training  section.  The administrative section schedules the activities of ships in  training  for  such  services  as  target  towing, photography,  and  dual-ship  exercises.  The  afloat training section handles the actual training aboard ship. It is organized into departments in the general pattern of shipboard  organization.  However,  the  engineering department  is  divided  into  two  departments: engineering and damage control. The FTG usually holds training exercises in three phases. 1. 2. 3. A training readiness evaluation (TRE) for ships in refresher training and an arrival inspection for ships  in  shakedown  training The  training  itself An  operational  readiness  evaluation  (ORE)  at the  end  of  training  for  ships  in  refresher  or shakedown  training Training Readiness Evaluation A TRE determines the ship’s organizational and material readiness to begin refresher training. FTG personnel do a TRE on a ship either in its home port or when it arrives at an FTG site. The TRE check-off lists are based upon standards prescribed by Battle Control, NWIP 50-l(B), Naval Ship's Technical Manual,  and directives of the fleet and type commanders. When   a   ship   is   scheduled   for   refresher   or shakedown training, the fleet  training  command  usually sends the ship information and instructions on the conduct  of  training  in  the  FTG.  They  also  send checklists for an arrival inspection or TRE.  The engineer officer should check his department’s organization and administrative procedures against the checklist(s). If the engineer  officer  corrects  most  of  his  discrepancies before the ship reports to the FTG, there will be more time for training. When FTG personnel begin the TRE, the ship’s engineering  department  should  provide  the  following assistance to the  team: 1. Furnish at least two ship’s personnel who are familiar with logs, records, and publications. 2.  Group  logs,  records,  and  publications  in  the sequence required by FTG instructions. 3. Assign one person, who knows the spaces and the  locations  of  posted  safety  instructions  and 3-2
