Pro- Submarine Activities, 



By the fall of 1943 Group M had grown to approximately 50 

 members snd It began to be apparent that operational research 

 could be of use to the Navy in studying other than anti-submarine 

 problemso A first broadening cf interest was in the direction 

 of aiding our own submarines . Dr„ Tate and Mr. To E. Shea 

 visited Pearl Harbor and discussed matters with Commander Sub- 

 marines, Pacific Fleet (ComSubPac), Shortly thereafter a re- 

 quest came from Pearl Harbor for the assignment of several 

 ASWORG members to assist the ComSubPac staff,, In answer to 

 the, request, Drs. Go E. Kimball and R, F. Rinehart were sent 

 to Pearl Harbor, Dr, Kimball to return after a short visit, 

 Dr. Rinehart to stay on indefinitely,, Subsequently, four 

 other Group M members were sent to work under Dr. Rinehart, 

 and a complete IBM installation was set up at Pearl Harbor. 

 Under Dr. Charles Kittel, a corresponding pro-submarine group 

 was set up at Washington to work on statistical and analytical 

 problems. 



During 1944 still other requests for members of Group M 

 came in from Naval units in the Pacific Vice Admiral T, C„ 

 Kincaid, Commander Seventh Fleet in the Southwest Pacific Area, 

 requested an anti-submarine analyst for his staff. Dr. Stein- 

 hardt was moved from his assignment with the Fourth Fleet In 

 Brazil and v/as sent to Brisbane, Australia, and later to Manus 

 (Admiralty Island) , in March 1944. Subsequently, he was re- 

 placed by Mr. A. M. Thorndike. In June Mr. R. E. Traber was 

 sent to Pearl Harbor to work with the Anti-Submarine Training 

 Unit in Fleet Airwing Two. He was later replaced by Mr. Gordon 

 Shellard. 



In the meantime, a new unit of OSRD, the Office of Field 

 Service, had been established and ASWORG transferred to it, 

 although it continued to operate as an integral unit, and 

 completely under Cominch control, most members of the staff 

 having been transferred In January 1944. From that time on, 

 Group M was not strictly a part of Division 6, though the 

 relationship between group and division remained practically 

 as close as before. 



In October 1944, the entire Group M v/as transferred back 

 to Readiness Division of Cominch and was reconstituted as ORG, 

 a part of the Research and Development Section with Dr. Morse 

 as Director. ASWORG became a sub-group assigned back to 

 Tenth Fleet, and other sub-groups were formally organized and
