INTRODUCTION TO SONAR 



SONAR TECHNICIAN RATING 



The Sonar Technician rating is a general 

 rating in the deck group (group I). The funda- 

 mental task of all Sonar Technicians is to 

 provide underwater data for operational use. 

 Sonar Technicians operate and maintain sonar 

 eqiupment, perform duties required as members 

 of antisubmarine (A/S) attack teams, and in- 

 terpret target and oceanographic data. At the 

 third and second class petty officer levels there 

 are two service ratings — one for men assigned 

 to surface ships and one for men assigned to 

 submarine duty. 



SONAR TECHNICIAN G 

 (SURFACE) (STG) 



Surface Sonar Technicians operate shipboard 

 antisubmarine equipment. This equipment in- 

 cludes sonars and underwater fire control systems 

 used in solving ASW problems. Equipment opera- 

 tion at the third and second class levels usually 

 is limited to manipulating dials and interpreting 

 received data. As an STG you must also be 

 able to perform operational, preventive, and 

 technical maintenance on sonar, underwater fire 

 control, and associated equipment. 



SONAR TECHNICIAN S 

 (SUBMARINE) (STS) 



Submarine Sonar Technicians operate sub- 

 marine sonar and oceanographic equipment, and 

 interpret data received from passive and active 

 sonars, submarine fire control equipment, and 

 associated auxiliary sonar equipment. As an 

 STS you also must be able to construct and 

 interpret submarine sonar plots, and perform 

 operational, preventive, and technical mainte- 

 nance on submarine sonar and associated equip- 

 ment, excluding fire control equipment. 



DUTY ASSIGNMENTS 



The majority of sea duty assignments for 

 Submarine Sonar Technicians are in submarines 

 and aboard submarine tenders. Most Surface 

 Sonar Technicians are assigned to destroyer- 

 type ships. Other sea duty billets include de- 

 stroyer tenders, antisubmarine aircraft carriers, 

 minesweepers, and certain cruisers. Some of 

 the locations of shore duty assignments, which 

 usually consist of instructor billets, are: U.S. 

 Fleet Sonar School, Key West, Florida; U.S. 

 Fleet Antisubmarine Warfare School, San Diego, 



California; U.S. Navy Submarine School, New 

 London, Connecticut; and Fleet Training Centers. 

 Shore duty billets of a general nature, common 

 to all ratings, are also open to Sonar Technicians. 

 Wherever you are stationed, one quality that 

 all petty officers must exhibit is leadership. As 

 you advance in rate, you will have more and 

 more responsibility, authority, and control over 

 other men. You must strive always to set a good 

 example for the men under you by maintaining 

 high standards of personal conduct, as well as 

 professional and military competency. In other 

 words, be a good Navyman. General Order 21 

 outlines the leadership qualities expected of all 

 persons in the Navy in a position of authority. 



ADVANCEMENT IN RATING 



Some of the rewards of advancement in 

 rating are easy to see. You get more pay. 

 Your job assignments become more interesting 

 and more challenging. You are regarded with 

 greater respect by officers and enlisted per- 

 sonnel. You enjoy the satisfaction of getting 

 ahead in your chosen Navy career. 



But the advantages of advancing in rating 

 are not yours alone. The Navy also profits. 

 Highly trained personnel are essential to the 

 functioning of the Navy. By each advancement 

 in rating, you increase your value to the Navy 

 in two ways. First, you become more valuable 

 as a specialist in your own rating. And second, 

 you become more valuable as a person who can 

 train others and thus make far-reaching con- 

 tributions to the entire Navy. 



HOW TO QUALIFY FOR 

 ADVANCEMENT 



Wliat must you do to qualify for advancement 

 in rating? The requirements may change from 

 time to time, but usually you must: 



1. Have a certain amount of time in your 

 present grade. 



2. Complete the required military and oc- 

 cupational training courses. 



3. Demonstrate your ability to perform all 

 the PRACTICAL requirements for advancement 

 by completing the Record of Practical Factors,

 Practical Factors may contain the old form 

 number, NavPers 760. 



4. Be recommended by your commanding of- 

 ficer, after the petty officers and officers super-
