 RMKS/1.  THIS ADVISORY IS ISSUED TO ENSURE THAT ALL OPERATORS OF               

 MK 26 GMLS (BASELINE 1) ARE AWARE THAT MANUAL LOAD OPERATIONS ARE              

 NOT REQUIRED TO SUPPORT ROUTINE TACTICAL OR TRAINING OPERATIONS.               

 THIS ADVISORY SUPERSEDES REF A AND IS APPLICABLE ONLY TO                       

 CG'S 47 - 51.                                                                  

                                                                                

 2.  BACKGROUND.  THE BASELINE 1 GMLS IS PROGRAMMED FOR OPTIMUM                 

 SAFETY DURING AUTOMATIC LOAD OF TACTICAL STANDARD MISSILES (SM).               

  THE ANNUAL LOAD OPTION IS ALSO AVAILABLE DURING ALL SYSTEM MODES              

 (I.E. TEST, TRAINING AND TACTICAL).  HOWEVER, IT IS NOT INTENDED               

 FOR USE DURING ROUTINE OPERATIONS.  THE SYSTEM IS DESIGNED TO                  

 PERMIT MANUAL LOADING OF A TACTICAL SM IN THE TEST OR TRAINING                 

 MODE.  UNLESS THE MISSILE SYSTEM SUPERVISOR IS CAREFUL IN THE USE              

 OF MANUAL LOADING, A TACTICAL SM MAY BE LOADED UNINTENTIONALLY.                

 THIS OCCURRED DURING A TRAINING EXERCISE IN WHICH THE MISSILE                  

 SYSTEM SUPERVISOR (MSS) WAS NOT FULLY AWARE OF LAUNCHER AND                    

 SYSTEM CONFIGURATION.                                                          

                                                                                

      A.  WHILE IT IS POSSIBLE TO MANUALLY LOAD A TACTICAL SM IN                

 THE TEST AND TRAINING MODES, AEGIS WEAPON SYSTEM (AWS) DESIGN                  

 WILL PREVENT AUTOMATIC LAUNCHING OF THE MISSILE.  THE PRESENCE OF              

 ENGAGEMENT ORDERS IN THE WEAPONS CONTROL SYSTEM (WCS) WILL                     

 INHIBIT MANUAL LOADING OF A LAUNCHER UNLESS THAT LAUNCHER IS                   

 FIRST REMOVED FROM PARTICIPATION IN COMPUTER CONTROLLED                        

 ENGAGEMENTS.  THE MSS MAY DO THIS BY USING A SIDE NOT AVAILABLE                

 AND B SIDE NOT AVAILABLE VARIABLE ACTION BUTTON ENTRIES.                       

                                                                                

      B.  SEVERAL ADDITIONAL INTERLOCKS BETWEEN THE MK 26 LAUNCHER              

 AND AWS MODES ARE ALSO ASSOCIATED WITH THE BASELINE 1 PROGRAM.                 

 THESE INTERLOCKS PREVENT AN AUTOMATIC LOAD ACTION OR ISSUANCE OF               

 A LAUNCHER ASSIGNMENT ORDER FOR AN INCORRECT MISSILE/MODE                      

 CONFIGURATION.  ALTHOUGH SUFFICIENT FOR SAFETY, THESE INTERLOCKS               

 ARE MINIMAL AND APPLY TO AUTOMATIC LOADING ONLY.  FOR                          

 CLARIFICATION, A SUMMARY OF INTERLOCKS WHICH ARE INCLUDED IN THE               

 PROGRAM PERFORMANCE SPECIFICATION FOLLOWS:                                     

                                                                                

                                                                                

                                                                                

           (1)  IF THE AWS MODE IS TEST OR TRAINING, USE OF THE                 

 LAUNCHER TACTICAL MODE IS PREVENTED.                                           

                                                                                

           (2)  IF THE AWS MODE IS TACTICAL OR TRAINING                         

 (SIMULATION)USE OF GMLS TRAINING SURFACE-TO-AIR MISSILES (TSAM)                

 OR GUIDED MISSILE TRAINING ROUNDS (GMTR) MODE IS PREVENTED.                    

                                                                                

           (3)  IF THE AWS MODE IS TACTICAL, USE OF THE LAUNCHER                

 SIMULATOR (MK 72) MODE IS PREVENTED.                                           

                                                                                

 3.  ACTION.  TO AVOID INADVERTANT MANUAL LOAD ACTIONS, CG 47 - 51
