NARR/REF A IS CLASS ADVISORY 08-84, REF B IS CSOSS PROCEDURE
OP2/SM (EXERCISE FIRING SUPPORT), REF C IS CSOSS PROCEDURE OP
1/ACTS(ACTS OPERATIONS).//
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
SHOULD MAKE THE FOLLOWING PEN AND INK CHANGES TO REFS B AND C:
A. REF B, SECTION I (PREFIRE), ADD THE FOLLOWING PRIOR TO

TASKED TO ADHERE TO THE PROVISIONS OF PARA 3.
5. THIS ADVISORY HAS NO IMPACT ON CMMP, PMS OR TECHNICAL
MANUALS. THE CONTENT OF THIS ADVISORY HAS ALREADY BEEN INCLUDED
IN THE BASELINE 1 COMPUTER PROGRAM DEFINITION DOCUMENT AS PROGRAM
ENGINEERING NOTE NO. 2. REVISIONS TO REFS B AND C ARE BEING
DEVELOPED AND CG'S 47 - 51 WILL RECEIVE THE NEW PROCEDURES AS
ROUTINE CSOSS UPGRADES INCIDENT TO REGULARLY SCHEDULED INDUSTRIAL
AVAILABILITIES. THIS ADVISORY WILL BE CANCELED WHEN CG'S 47 - 51
HAVE RECEIVED CSOSS UPGRADES.
