D: Dratta ot proposed letters to Director,

1. a. .Attached hereto, lnclosure A., is a proposed organisational 

structure for the subject conference. In brie1', it proposes the following groups; each ot which would have U.S. and British members: 

(l) A PleDal"J' Committee 

(2) .ln Executive Committee 

(3) J. SUbcomittee for CCM attaira 

(4) A Subcommittee tor other than CCJI affairs, 

with f'our Working Groups each of' which 

is assigned a specitic area ot the wort 

to be done. 

b. It mq pron inexpedient for the British to have the 

Conference organized as indicated above. However, the division o£ the 

actual work to be dona into tour areas is logical, in view ot Enclosure 

B to Reference A, and we could propose to the British that such a 

division be accepted tor the Combined Conterence, if' feasible for them. 

2. a. In Enclosure A I have indicated 1117 suggestions as to 

the U. s. composition of the Executive Connittee, and tor the u. s. 

Chatrman ot each of the auboomitteea. The .tall U. s. composition of 

each o£ the subcommittees and of the Working Groups should be determined 

by the u. S. Executive Committee in collaboration with the U. S. 

Chairmen of the two subcommittees. It the foregoing meets with 7f11Jr 

approval, I propose to call a meeting of the U. s. Executive Committee 

for that purpose and tor ether preparator;y discussions.

b. In connection with this matter ot U. S. m•bership it will 

be noted that I propose U. S. representation from. the Service 

Cl7Ptol0gic Agencies on each ot the two subcommittees. Before the 

arrival ot the despatch from GCHQ to Brigadier Tiltman relative to 

the composition ot the British Delegation (Bnclosure B), I bad 

thought that representation from the u.s~ Sel"V'ice Cryptologic 

.Agencies would be adequate to represent their interests, as well 

as those ot the coamunication sel"V'ices ot the JrlV1 Haq, and Air 

Force, since onll' research and development aspects and the lim1.ted 

exchange ot crypto-principles were involYad. But I note that the 

British Delegation inoludea~ lwh~ is to represent the 

"operational requirements o the three services,• and this somewhat 

changes the picture. I therefore suggest that it would be logical 

and a good political gesture to invite General McClelland to be a 

member ot the U.S. Delegation and to designate two ottioera ot 

hi• organization to represent JCIXl and other Service intareata in. 

the matters to be discuss.a. in the two subcOBD.ittees of the 

Conference. Slleh JCIC repl"eaentatives could be designated tull 

members ot the Conference or thq could serve at least in the 

capacity of observers. I•recmmeml the former twe of participt1tion

3. a. Encloaure c' a letter dated 14 .&ugust 1950 from. ass 

on the sa.bject conference baa bean studied and coordinated with 

.&FSA-OJ and JPSA-04. The additional subjects recommended tor 

inclusion in the Agenda are logical and the onq additional it•s 

which the u. s. would have to discuss or demonstrate are the Y-8, 

ASAD-1, and JFSAL 5104. There are no reasons wb1' &JV' of these 

subjects or itmns should be withheld from the British. Thq have 

bean included 111 Enclosure A. 

b. Col. Collins •• ot the opinion that no further action 

or approval b;y .Ai'SA.C is necea8817 1n order to add the items desired 

b7 AlSS to the agenda which .AFSAC approved 111 AFSAC 63/l. HoRV'er, 

AFSA-OJ, 04, l2 and l4 are of the opinion that specific approval ot 

AFSAC should be obtained tor these additiou and that such approval 

could be obtained oraJ.l1'. In view of the tact that a regular Al'SAC 

meeting is scheduled tor 25 August, perhaps you can present the matter 

oralq at that meeting and obtain the approval desired. In coordination with AFSA-12 I prepared a draft of a statement to be ma.de to 

AFSlC on this point and thought it advisable to include provision in 

the stat•entto cover the contingenq that the U.S. or the British 

might wish to discuss additional equipments, it considered consonant 

with the general JCS directive tor the Conference. I beline 7ou have 

alreadJ' seen that statement.

4. a. This morning I received word froa Brigadier Tiltman 1 s 

office that the British partT is detiDitai,- sailing on the Qu.ean 

Elizabeth leaving London DD 14 September. Theref"ore, the opening 

session could be held on 19 or 20 September, the latter being 

preferable. It is belined desirable that prior to the arrival at 

the British Delegation the U'. S. m•bars of the various Comittees, 

Subcommittees, and Working Groups proposed herein should get together, 

to receive :lnatructiona for their gu.idance in participating 1D the 

discussion, tor gaining an understanding or the various limitations 

on matters to be discussed in Combined meetings, and tor determiDing 

the position to be taken DD certain questions which mq be delicate 

or involve matters o:t polic7. For this reason it is desired to 

determine as soon as practicable the tull U. s. oompoaitien of each 

COlllllittea, Subcommittee, and Working Group, ao that u. S. meetings 

can SOOD begin. 

b. The designation of .APSA membership can be made without 

delq. The designation of members from outside 1FSA should be 

undertaken at once, ao that meetings of U. s. representatives on 

Subcommittees A and B and the Working Groups can be initiated as 

prompti,- as practicable. 

o. It 'llllq' be advisable to write formal memoranda or 

letters to the Service Cl"1Ptologic Agencies and to the Director, 

C0111111unications-Electronics, requesting their designations of members 

to participate in the work of the Conference. Attached hereto are 

drafts of such memoranda or letters (Enclosure D). 

5. A aun97 of the available apace in Building 17 indicates that 

plenty of good working space, praaentq assigned to AFSA-14, ia 

available in the third floor area thereof. Although the area 1a 

not compartmented into separate rooaa with doors into each, except 

tor one room {17-319), the ba;ya are large enough so that working groups 

can work sinmltaneousq without contusion. It mq be possible and 

it would be beat to establish the headquarters tor the British Delega.-

tion and the Conference Room tor SubcDlllllittees A and B, all within 

that area. Arrang•enta will be u.de to reserve the NCS Lounge tor 

the opening and closing plenary sessions, and to schedule reservations 

ot conference rooms 1212 and l9-l2S. I have had prel!mina.17 conf'arences 

with AFSA.-OS on the toregoing matter ot apace, facilities, and 

secretarial assistance for the Conf erenca. I asaume that your office 

will arl"Bl'lg8 tor &f1T official social affairs in connection with the 

Conf ere:nce.
