AsDevLant. 



Still another important development was the formation in 

 February 1943 of Aircraft Antisubmarine Development Detach- 

 ment, Atlantic Fleet (AirAsDevLant ) . This unit, under Commander 

 Air ForceSj, Atlantic Fleets and combining the activities of the 

 tactical development unit and the specialist training unit, 

 filled a long-felt need for an organization which would carry- 

 on tactical experimental work in antisubmarine operations and 

 which would at the same time provide operational training for 

 antisubmarine air crews. The commanding officer of the detach- 

 ment was Capt. Vosseiler who had been connected with the early 

 development work of ASW0RG o The unit wa,s located at Quonset 

 Point , Rhode Island 



In response to a request for technical help Drs = Co F. 

 Squire and W, Jo Horvath* were assigned first to the unit and 

 later Dr. Bell was transferred there the next July, 



The ASWORG unit at Quonset worked on a great variety of 

 problems o They helped to devise tactical and operational 

 tests of new equipment^, and to write the manuals and tables 

 to govern its use They helped test various types of new 

 low-altitude bombsights. They made calculations for proper 

 sighting and inter valometer settings for glide bombing. They 

 devised procedures for the testing of rockets, and devised 

 arid analyzed a variety of tests having to do with visual and 

 radar sighting. They helped in the establishment of methods 

 for the effective utilization of sonobuoys and investigated 

 the proper tactic? for searchlight planes. In July the re- 

 sponsibilities of the Air Ai ~i submarine Development Detachment 

 were broadened to include tactical experimental work with 

 surface craft. The "Air' 1 was dropped from m: .''3 title 

 and it became the Antisubmarine Development Detachment 

 (AsDevLant) o The original Group mit became the Aircraft 

 Division of the new detachment and a new co-equal Surface Divi- 

 sion was addedc Dr, H, ho Elliott was assigned to the Surface 

 Division and assisted Commander H. R. Hummer, section head, in 

 testing various sonic and other detection gear., Mr. J* K» 

 Tyson was also assigned to the Surface Division which he. aided 

 by analyzing trials of surface vessel attack procedure, 



The inauguration of the carrier escort group as a major 

 factor in antisubmarine warfare confronted Group M with a 

 set of new problems. In order to study these problems at 

 first hand Dr. Wo E. Albertson was sent on an operational trip.
