was possible bo concentrate on information of immediate 

 use to them. The school concentrated on gear widely U3ed 

 by the fleet and not on new equipment »- at least not 

 until it was installed in considerable quantity. 



The sonar course proved hig 1 sffective, not only 

 because the men could now use their ships to better 

 advantage on war patrol, but the additional training 

 enabled them to repair equipment casualties at sea. 



Field engineers also gave -nderway instruction to sub- 

 marine crews o At Pacific submarine b^es, '.he engineers 

 would go out on every submarine for one or two days instructing 

 crews on the ooeration of electronic equipment

The assistance given to staff commands was varied and 

 extensive. Operating through the Bureau of Ships, at Ijavy 

 yards and stations or with the forces afloat, field engineers; 

 1) modified a device for improving training facilities at 

 the San Diego Fleet Sound School; 2) made circuit modifi- 

 cations and additions, and changed RCA sound gear so it could 

 be used with a Harvard Underwater Sound Laboratory BDI on 

 ASW training ships; 3) redesigned arrangement of sonar 

 equipment in DE sonar huts, making the equipment more ac- 

 cessible and easier to maintain ana operate; 4) introduced 

 equipment and techniques of checking ship's sonar equipment 

 on arrival or departure; 5) at the Chicago Navy Pier and 

 the Treasure Island Training Schools,, assisted with planning 

 lay-out of equipment , procurement and installation of equip- 

 ment, planned the curriculum, trained Instructors; 6) planned 

 and directed an expendable radio sonobuoy (ERSB) school for 

 air force personnel at ASW headquarters^ Oahu, and at the same 

 time aided in solving problems of launching certain devices, 

 designed a floating triplane radar target, and established a 

 communications system for aircraft and ground station coordina- 

 tion; 7) supervised training, and development of attack tech- 

 niques at the Submarine Chaser Training Center, Miami; £) 

 assisted in improving the use of sound equipment, repaired 

 equipment, trained personnel on destroyer escort shakedown 

 cruises o 



Detection of Fundamental or Type Equipment Difficulties. 



An important part of the field engineer's duties was to 

 locate and diagnose equipment difficulties of recurrent 

 character, making changes or corrections in the field, then
