CINCPACFLT  are  directly  under  the  Chief  of  Naval Operations (CNO). The CNO is the Navy representa- tive   for   the   Joint   Chiefs   of   Staff.   They   have   the responsibility for the protection of the United States. Q2-26. The    commander    of    a    carrier    division    is usually an officer of what rank? Q2-27. Who is the Navy representative for the Joint Chiefs of Staff? TYPICAL CARRIER SCHEDULE LEARNING OBJECTIVE: Identify the purpose of the carrier schedule. A  carrier  needs  periodic  repair  and  refitting.  The time scheduled for this work is called a yard period. In a Navy shipyard, the carrier is repaired and any change or modernization is done. Included are rearrangement of compartments, repair of machinery, and installation of new systems. At this time, required supplies and spare parts  are  loaded  aboard  for  both  the  carrier  and  its supported squadrons. The   carrier   then   takes   several   shakedown   and training   cruises.   During   the   shakedown   cruises,   the carrier   is   checked   for   satisfactory   operation   of machinery,  equipment,  and  systems.  A  return  to  the shipyard   may   be   needed   to   correct   discrepancies. During  the  training  cruises,  the  squadron's  and  ship's personnel   are   trained   in   operations   and   procedures necessary to complete the ship's mission. The carrier proceeds to its patrol area and conducts operations   according   to   its   mission.   Supplies   are provided by supply ships by underway replenishment (UNREP), carrier onboard delivery (COD) aircraft, or by   vertical   replenishment   (VERTREP)   helicopter squadron's. The carrier usually takes a breather one or more times during this deployment period. This break allows personnel to go on liberty in foreign countries, and bring supplies on board that are difficult to get at sea. After the deployment period, the carrier returns to its homeport for refitting. Each return to home port does not  involve  a  yard  period.  While  the  carrier  is  home ported,   the   squadrons   that   were   aboard   are   based ashore.     While     the     carrier     is     being     refitted     and re-supplied  during  home  port  periods,  personnel  are transferred and new personnel are trained. The carrier is now ready for deployment. Q2-28. Define   a   "yard"   period   as   it   relates   to   an aircraft carrier. Q2-29. How    are    aircraft    carriers    supplied    with provisions during deployment? DESIGNATION AND TYPES OF NAVAL AIRCRAFT LEARNING   OBJECTIVE:    Identify   naval aircraft    designations    and    the    major    fleet aircraft. The  present  system  of  designating  naval  aircraft was initiated in late 1962. This system applies to all U.S. military aircraft. All the aircraft designations have one thing in common—a hyphen. The letter just before the hyphen specifies the basic mission, or type, of aircraft. The basic mission letters are as follows: A—Attack B—Bomber C—Transport E—Special electronic installation F—Fighter H—Helicopter K—Tanker O—Observation P—Patrol R—Reconnaissance S—Antisubmarine T—Trainer U—Utility V—VTOL and STOL X—Research If the aircraft has been modified from its original mission,  a  letter  in  front  of  the  basic  mission  letter indicates  its  modified  mission.  Mission  modification letters are as follows: A—Attack C—Transport D—Director    (for    controlling    drone    aircraft    or missiles) E—Special electronic installation H—Search/rescue K—Tanker L—Cold-weather  aircraft  (for  Arctic  or  Antarctic operations) M—Mine countermeasures O—Observation P—Patrol Q—Drone R—Reconnaissance S—Antisubmarine T—Trainer U—Utility V—Staff W—Weather All   the   aircraft   designations   have   one   thing   in common—a hyphen; for example, the F/A-18E Hornet 2-17
