Morse and Shockley also went over as special OSRD representa- 

 tives, they reported collaterally to Mr. Bennett Archambault , 

 head of the OSRD London office, Mr. Archambault made arrange- 

 ments for >j rice s : ar • transport tion facilities and was 

 helpful in arranging contacts for the two representatives 

 of Group M. 



Many contacts had to be made. The Admiralty had opera- 

 tional responsibility for anti-submarine warfare, routed the 

 convoys, and controlled the destroyer escorts on the British 

 side of the Atlantic „ The Admiralty also had operational 

 control ever Coastal Command's anti-submarine planes, 



A particular problem which required settlement grew out 

 of the fact that the AAFAC squadron of 3-24 's were the first 

 anti-submarine planes in England to have S-band radar sets 

 British plans - arrangements for blind landings and so on - 

 were built around the longer wave ASV Mark II sets. Conse- 

 quently, many complications arose. Further troubles grew cut 

 of the fact that the American squadron had beer assembled 

 hastily and had not had an opportunity for thorough radar 

 training,, Thus the 1 erent advantages of the S-band radar 

 gear were net immediately realized. Following considerable 

 discussion, the members of she squadron ^:evc ^iven extra time 

 for further training ar ". were just about ready to go into 

 action when they transferred again, this tine at a base in 

 Casablanca in North Africa. There bhey subsequently performed 

 much useful work. 



Negotiations for closer liaison with the operational re- 

 search group of the Coastal Command were aided by the presence 

 of Mr. J. Po T„ Pearman, a pioneer member of the CR5 group, 

 who had earlier in 1342 visited the United States at the time 

 a Coastal Command squadron was sent to this country to assist 

 in anti-submarine work In the Caribbean. Mr. Pearmar had 

 spent considerable time In bringing t] : lembers or A3W0RG up 

 to date on the work of their opposite numbers in Great Britain, 



Through Prof. Blackett, Dr. Morse and Col. (now Brigadier 

 General) Schonland, head of the Army Operations Research Group, 

 a visit was also made to the Eighth Bomber Command, U. 3, AAF ; 

 and to the Army Operations Research Group, assigned to that 

 command. The members of this group under the leadership of 

 Mr. J. M. Harlan were recent arrivals and were busily sorting
