3. CHANGING DEPTH FROM SAFE DEPTH TO PERISCOPE DEPTH
(THIS PARA WILL REPLACE THE ENTIRE SUB-PARA 0206-4 OF EXTAC 1005.)
A) SURFACING PROCEDURE ALFA.
SURFACING METHOD ALFA IS THE STANDARD METHOD FOR A SUBMARINE TO CHANGE DEPTH FROM SAFE DEPTH TO PERISCOPE DEPTH AT FINEX OR STOP TIME.  METHOD ALFA IS A CONTROLLED PROCEDURE FOR BRINGING SUBMARINES

TO PERISCOPE DEPTH AT FINEX OR STOP TIME, REQUIRING COMMUNICATIONS BETWEEN THE SHIP TASKED WITH THE PROCEDURE AND THE SUBMARINE.
B) CONDUCT OF THE SUBMARINE.
A SUBMARINE INTENDING TO COME TO PERISCOPE DEPTH (PD) FROM SAFE DEPTH WHEN SHIPS AND/OR HELICOPTERS ARE IN THE VICINITY IS TO CARRY OUT THE FOLLOWING PROCEDURES UNLESS RELAXATIONS 3*K, 8*E AND /OR 9*F ARE IN FORCE:
I) TURN TO SAFETY COURSE
II) FIRE TWO YELLOW/WHITE PYROTECHNICS SIGNALS SPACED 3 MINUTES APART, USING SMOKE BY DAY AND LIGHT BY NIGHT. ON FIRING EACH SMOKE/LIGHT TRANSMIT "QQQ" BY UWT OR SST. (TABLE I)
III) UPON RECEIPT OF "DDD" AND /OR FIVE CHARGES, THE SUBMARINE RETURNS TO PD IF THE SUBMARINE CO IS SATISFIED THAT IS IT SAFE TO DO SO. ONCE AT PD, THE RESPONSIBILITY FOR AVOIDING COLLISION RESTS ENTIRELY WITH THE SUBMARINE CO.
IV) IF SIGNAL "JJJ," SIGNAL A3, AND/OR MK 84 CODE 2 ARE RECEIVED, REMAIN AT SAFE DEPTH. MARK POSITION UPON RECEIPT OF SIGNAL "QQQ" OR SIGNAL A2.  RESTART SURFACING PROCEDURES AFTER SIGNAL "PPP" IS RECEIVED
V) ONCE  AT PD , INFORM SURFACE UNITS THAT THE SUBMARINE IS AT PD. C) CONDUCT OF SHIPS AND HELICOPTERS
ALL ASW UNITS IN THE VICINITY OF A SUBMARINE KNOWN TO BE COMING TO PD ARE TO ACT AS FOLLOWS:
I) RAISE HELICOPTER SONAR SYSTEMS, DECOYS,  TO A DEPTH OF 30 M OR LESS, OR THE SHIPS DRAFT AUTHORISED BY RELAXATION 12*B.
RAISE VDS/DTAS TO A CABLE LENGTH NOT EXCEEDING 30 M OR THE CABLE LENGTH AUTHORIZED BY RELAXATION 8*G.
INFORM THE ASW UNIT ASSIGNED THE RESPONSIBILITY FOR SURFACING THE SUBMARINE OF THE ACTUAL VDS/DTAS LENGTH AND DECOY , SONAR SYSTEM DEPTH.
II) TAKE STATION TO REMAIN A DISTANCE OF AT LEAST 1500 YARDS FROM THE SUBMARINE COURSE, IF KNOWN. STEER THE SAFETY COURSE OR ITS RECIPROCAL.
III) DURING THE ENTIRE TIME THAT THE SUBMARINE IS COMING TO PD, PROCEED ABOVE CAVITATION SPEED AT NOT LESS THAN 12 KNOTS. SECURE NOISE MASKER SYSTEMS AND SWITCH OFF OR RECOVER DECOYS. AT NIGHT, SHOW NAVIGATION LIGHTS AT FULL BRILLIANCE. IF THE SHIP MUST STOP DURING THE SURFACING PROCEDURE, IT IS TO TAP THE HULL, RUN ITS ECHO SOUNDER, AND GENERATE AS MUCH NOISE AS POSSIBLE UNTIL VOICE COMMUNICATION IS ESTABLISHED WITH THE SUBMARINE.
IV) SONARS
SHIPS FITTED WITH MEDIUM OR LONG RANGE SONAR SYSTEMS MAY TRANSMIT AT LOW POWER, PROVIDED UNDERWATER TELEPHONE COMMUNICATIONS CAN BE ESTABLISHED AND MAINTAINED.
SHIPS WITH VDS/DTAS STREAMED (RELAXATION 8*G) ARE TO APPLY THE FOLLOWING SPECIAL TRANSMITTING PROCEDURES
A) IF THEY HAVE A SHORT RANGE SONAR - NORMAL TRANSMISSION WATCH.
B) IF THEY HAVE MEDIUM OR LONG RANGE SONAR - NORMAL TRANSMISSION AT LOW POWER OR 3 TRANSMISSIONS EVERY 5 MINUTES IF REQUIRED TO ESTABLISH AND MAINTAIN UWT COMMUNICATIONS. IF UWT COMMUNICATIONS CANNOT BE ESTABLISHED - NORMAL TRANSMISSION WATCH.
C) IF THEY CANNOT TRANSMIT WITH ANY OF THEIR SONAR SYSTEMS, TRANSMIT "VDS" ON UWT EVERY 5 MINUTES.
V) EXCEPT IN AN EMERGENCY, UNITS SHOULD NOT TRANSMIT ON UWT FROM THE TIME THE SUBMARINE ACKNOWLEDGES THE ALL-CLEAR-TO-SURFACE SIGNAL "DDD" UNTIL THE SUBMARINE IS AT PD. KEEP A SHARP LOOKOUT FOR THE SUBMARINE WHILE IT IS COMING TO PD. SHOULD THE SUBMARINE BE ON A COURSE OR IN A POSITION OTHER THAN ANTICIPATED, SHIPS SHOULD BE READY TO MOVE CLEAR OF THE SUBMARINE IMMEDIATELY.
D) CONDUCT OF ASW UNITS RESPONSIBLE FOR EXECUTING THE SURFACING PROCEDURE.
THE ASW UNIT ASSIGNED BY THE OTC/OCS WITH THE RESPONSIBILITY OF BRINGING THE SUBMARINE UP TO PD, SHOULD IN ADDITION TO SUBPARA III: I) WARN UNITS WHICH ARE NOT COMPLYING WITH THE PRECEDING PROCEDURES II) MAINTAIN UWT LISTENING WATCH
III) EXCHANGE RANGE BY MARK - SNAP METHOD
(SEE DESCRIPTION OF -"VFM"- TABLE J)
IV) UPON SIGHTING THE FIRST PYROTECHNIC FROM THE SUBMARINE TRANSMIT "ROGER SMOKE, BEARING ..." ON UWT OR "QPQ" ON SST
V) UPON SIGHTING THE SECOND PYROTECHNIC FROM THE SUBMARINE, TRANSMIT "ROGER SMOKE, BEARING ..." ON UWT OR "QPQ" ON SST
VI) PASS A SURFACE SITUATION REPORT ON UWT
VII) INFORM THE SUBMARINE OF ANY SHIP IN THE VICINITY WHICH HAS VDS/DTAS STREAMED TO A GREATER DEPTH THAN ALLOWED DURING THE SURFACING PROCEDURE, AND OF THE DEPTH TO WHICH THE VDS/DTAS IS STREAMED. THIS MAY BE NECESSARY IF BAD WEATHER RESTRICTS THE RECOVERY OF VDS/DTAS
VIII) ONCE THE POSITION OF THE SUBMARINE HAS BEEN DEFINITELY ESTABLISHED AND IT IS SAFE FOR THE SUBMARINE TO COME TO PD IN THE NEXT 10 MINUTES, TRANSMIT "DDD" ON UWT OR SST OR SIGNAL A-5 (FIVE CHARGES) OR SIGNAL MK84 CODE 3, UNLESS RELAXATION 3*E IS IN FORCE. IF IT IS NOT SAFE FOR THE SUBMARINE TO COME TO THE PD, PASS "JJJ" ON UWT OR SST , SIGNAL A-3 (THREE CHARGES) OR SIGNAL MK84 CODE 2. IF IN ANY DOUBT THAT "JJJ" OR MK84 CODE 2 HAS BEEN RECEIVED BY THE SUBMARINE, THE SIGNAL A-3 MUST ALSO BE MADE.
IX) IF  "JJJ," SIGNAL A-3, OR SIGNAL MK84 CODE 2 HAVE BEEN MADE, THE ENTIRE SURFACING PROCEDURE MUST BE RESTARTED AS DESCRIBED BEFORE.
X) THE SURFACING PROCEDURE MAY BE CONSIDERED AS COMPLETED WHEN THE SUBMARINE HAS REPORTED THAT IT IS AT PD AND OPERATIONS NORMAL.
XI) IF NO COMMUNICATIONS HAVE BEEN ESTABLISHED AT STOPTIME PLUS ONE HOUR, RETURN TO THE LAST KNOWN POSITION OF THE SUBMARINE, INITIATE A SEARCH, ATTEMPT TO ESTABLISH COMMUNICATIONS BY ALL MEANS POSSIBLE, AND FOLLOW THE INSTRUCTIONS IN ATP-10(D).
E)  SURFACING METHOD BRAVO.
SURFACING METHOD BRAVO IS AN ALTERNATIVE METHOD FOR A SUBMARINE TO CHANGE FROM SAFE DEPTH TO PERISCOPE DEPTH AT FINEX OR STOP TIME.  IT IS ONLY TO BE USED WHEN RELAXATION 3*J IS AUTHORIZED FOR USE, AND WHEN ORDERED IN THE EXERCISE MESSAGE.  METHOD BRAVO ALLOWS THE SUBMARINES'S COMMANDING OFFICER TO BRING HIS SUBMARINE TO PERISCOPE DEPTH EXPEDITIOUSLY AND SAFELY UPON EXERCISE COMPLETION.  THIS IS ACCOMPLISHED BY SURFACE UNITS STEERING SAFETY COURSE OR ITS RECIPROCAL WHILE CAVITATING AND TRANSMITTING ON SONARS AND CLEARING THE IMMEDIATE AREA IN WHICH THE SUBMARINE WAS OPERATING (REGARDLESS OF THE SUBMARINE'S ESTIMATED POSITION AT FINEX OR STOP TIME).  WHEN RELAXATION 3*J IS IN FORCE, A SUBMARINE INTENDING TO COME TO PD FROM SAFE DEPTH WHEN SHIPS AND/OR HELOS ARE IN THE VICINITY, IS TO CARRY OUT THE FOLLOWING PROCEDURES UNLESS RELAXATION 3*K AND/OR 8*E ARE IN FORCE.
F) CONDUCT OF THE SUBMARINE
I) TURN TO SAFETY COURSE
II) MAY FIRE PYROTECHNICS TO INDICATE POSITION; AND
III) WHEN IT IS SAFE TO DO SO BY THE CO, RETURN TO PD AND CONTACT THE OTC/OCS ON  ALLOCATED UHF, HF OR VHF FREQUENCY .
G) CONDUCT OF SHIPS AND HELICOPTERS
ALL ASW UNITS IN THE VICINITY OF A SUBMARINE KNOWN TO BE COMING TO PD ARE TO ACT AS FOLLOWS:
I) RAISE HELICOPTER SONAR AND  DECOYS TO A DEPTH OF 30 M OR LESS OR

TO THE REDUCED SHIP'S DRAFT WHICH MAY BE AUTHORIZED BY RELAXATION 12*B. BEFORE FINEX OR STOP TIME, RAISE VDS/DTAS TO A CABLE LENGTH NOT EXCEEDING 30 M, OR THE CABLE LENGTH AUTHORIZED BY RELAXATION 8*G . II) ASSUME THE SAFETY COURSE OR RECIPROCAL, WHICHEVER COURSE OPENS FROM THE LAST KNOWN POSITION OF THE SUBMARINE. AT TIMES, IT MAY BE DESIRABLE FOR THE OTC/OCS TO ORDER SHIPS TO STEER EITHER THE SAFETY COURSE OR THE RECIPROCAL IF THE OCS WISHES TO KEEP THE FORMATION TOGETHER FOR SUBSEQUENT OPERATIONS. THIS SHOULD ONLY BE DONE IF THE SUBMARINE'S POSITION IS KNOWN AND ALL SHIPS ARE DISPLACED AT LEAST 1500 YARDS OFF THE SUBMARINE'S COURSE.
III) DURING THE ENTIRE TIME THAT THE SUBMARINE IS COMING TO PD, PROCEED ABOVE CAVITATION SPEED, BUT NOT LESS THAN 12 KNOTS. SEC
