CG 47 CLASS ADVISORY NO. 10-89 VERTICAL LAUNCH SYSTEM MAGAZINE AUTHORIZATION A. TECHNICAL MANUAL S9410-AJ-AEG-030, AEGIS COMBAT SYSTEM CONSOLE SUPERVISORS OPERATING PRINCIPLES AND PROCEDURES B. WEAPONS CONTROL SYSTEM MANUAL S9410-AJ-AEG-280, QUICK REFERENCE GUIDE FOR MISSILE SYSTEM SUPERVISOR 1. THE PURPOSE OF THIS CG47 CLASS ADVISORY IS TO ALERT COMBAT SYSTEM PERSONNEL TO POTENTIALLY MISLEADING INDICATIONS OF VERTICAL LAUNCH SYSTEM (VLS) MAGAZINE AUTHORIZATION. UNDER CERTAIN CIRCUMSTANCES, IT IS POSSIBLE FOR THE MISSILE SYSTEM SUPERVISOR (MSS) TO BELIEVE HE HAS REMOVED MAGAZINE AUTHORIZATION FROM A LAUNCHER, WHILE IN FACT THAT LAUNCHER CAN STILL LAUNCH MISSILES. 2. MAGAZINE AUTHORIZATION IS USED BY COMMAND AND DECISION (C & D) TO CONTROL SELECTION OF ALL MISSILE TYPES IN EACH LAUNCHER. VLS WILL NOT SELECT A MISSILE FROM A LAUNCHER IF IT HAS RECEIVED A VALID COMMAND FROM C&D VIA A WEAPONS CONTROL SYSTEM (WCS) TO REMOVE MAGAZINE AUTHORIZATION. HOWEVER, IF ANY CELL HAS ALREADY BEEN SELECTED IN A LAUNCHER AT THE TIME AN ORDER IS RECEIVED TO REMOVE MAGAZINE AUTHORIZATION FOR THAT LAUNCHER, VLS REJECTS THE COMMAND AND MAINTAINS THE LAUNCHER STATUS AS MAGAZINE AUTHORIZED. 3. MAGAZINE AUTHORIZATION VARIABLE ACTION BUTTONS (VAB) CAN BE ACCESSED BY C&D OPERATORS, EITHER THE TACTICAL COMMAND (TC) OR THE COMBAT SYSTEM COORDINATOR (CSC). IF A C&D OPERATOR ATTEMPTS TO REMOVE MAGAZINE AUTHORIZATION FROM A LAUNCHER WITH A CELL SELECTED, THE CUE LAMP FOR THE VAB CORRECTLY BLINKS SHOWING THAT THE LAUNCHER HAS NOT REMOVED AUTHORIZATION. THE VLS INVENTORY AND STATUS DISPLAY ALSO SHOWS THE CORRECT LAUNCHER AUTHORIZATION. THIS IS BECAUSE C&D MONITORS THE VLS REPORTED AUTHORIZATION STATUS TO ENSURE THAT THE REPORTED AUTHORIZATION AGREES WITH THE ORDERED AUTHORIZATION. 4. THE CURRENT WCS DESIGN SUPPLIES THE MSS WITH VABS LABELED "FWD MAGZNE AUTH" AND "AFT MAGZNE AUTH". THESE LABELS ARE INCORRECT AS THEY GIVE THE MSS OPERATOR THE IMPRESSION THAT HE CAN ENABLE OR REMOVE MAGAZINE AUTHORIZATION WHEN HE CAN ONLY ENABLE OR REMOVE STANDARD MISSILE (SM) AUTHORIZATION FROM THAT MAGAZINE. DEPRESSION OF ONE OF THESE VABS DOES NOT RESULT IN WCS ORDERING VLS TO CHANGE MAGAZINE AUTHORIZATION, BUT MERELY PROVIDES OR REMOVES PERMISSION FOR WCS TO USE THAT LAUNCHER FOR SM ENGAGEMENTS. WHEN A MSS MAGAZINE AUTHORIZATION VAB IS USED TO PREVENT SM LAUNCHES FROM A LAUNCHER, IT DOES NOT AFFECT AUTHORIZATION TO LAUNCH TOMAHAWK OR VERTICAL LAUNCH ASROC (VLA) MISSILES FROM THAT LAUNCHER. 5. A CHANGE TO THE AEGIS WCS COMPUTER PROGRAM TO CORRECTLY INDICATE THE SM PERMISSION STATUS IN THE MSS SUBMODE IS UNDER DEVELOPMENT. A RENAMING OF THE MSS "MAGZNE AUTH" VABS IS ALSO BEING DEVELOPED. THESE CHANGES WILL BE INCLUDED IN COMPUTER PROGRAM DELIVERY 2.2 SCHEDULED FOR DELIVERY STARTING DEC 89. 6. ACTION. UNTIL THE CHANGES ARE IMPLEMENTED THE FOLLOWING ACTIONS SHOULD BE TAKEN: A. FOR CG47 CLASS SHIPS: INSURE THE MSS OPERATORS ARE AWARE THAT THE MSS "MAGZNE AUTH" VABS AND THE MAGAZINES AUTH STATUS DISPLAYED ON THE MISSILE SYSTEM SUMMARY DISPLAY RELATE TO MSS PERMISSION TO USE A LAUNCHER FOR SM ENGAGEMENTS. B. FOR AEGIS TRAINING CENTER: ENSURE THAT THIS INFORMATION IS EMPHASIZED IN THE CIC OPERATOR'S COURSE TRAINING MATERIALS. 7. FOR COMNAVSURFPAC/COMNAVSURFLANT: REQUEST TASK CG 47 CLASS SHIPS TO ADHERE TO GUIDANCE OF PARA 6A ABOVE. 8. THIS CLASS ADVISORY HAS NO EFFECT ON EOSS, CSOSS, OR PMS. THE WEAPONS SYSTEM FILE, REF A, REF B, AND TRAINING PROGRAMS WILL BE UPDATED WITH THE NEXT PROGRAM UPDATE. 9. THIS CLASS ADVISORY WILL BE CANCELLED WHEN THE WCS COMPUTER PROGRAM HAS BEEN MODIFIED TO CORRECTLY INDICATE SM PERMISSION STATUS, THE "MAGZNE AUTH" VABS ARE RENAMED IN THE MSS SUBMODE AND REFERENCES A AND B AND THE TRAINING PROGRAMS HAVE BEEN UPDATED. 10.
