b. Admiral Stone indicated that these additional names v.rould be 

sent to the Chairman, RDB, \'Tho would either himself arrange 

f'or approaching the companies and candidates concerned., or 

delep,ate this to ~FSA. 

4. TJIRAFSA mentioned briefl.y the interest of C;J:A in the establishment 

ot SCAG and £or that reason indiented the need for having SCAG be prepared 

and briefed as soon as practicable so as to enable its members to undertake 

1vithout dela;r a consideration of the specific COr.:INT problems of' primary 

concern to CIA as well as AFSA. 

5. a. LCDR Gleason outlined his general suggestions as to a proper 

program, indicating that it might well consist of the following 

four phases: 

(1) Introductory indoctrination and briefing, with assurances 

of AFSA's appreciation of the fact that there must be a 

complete disclosure or the details of the specific 

problems A.FSA desires SCAG to consider, ii' the members of 

SCAG are to make worthwhile contributions to their solution. 

Nothing essential or desirable for them to kno\11 should be 

1:'1ithheld. 

(2) A.rousing interest in those problems by indicating the 

importance and value their solution w·o•1ld have in national 

defense. 

(3) Presentation(s) to give those members or SCAG i·rho have had 

no previous contact 'ti'dth COIITNT some idea ae to the ecope and 

ccu"D.plexity or, and the general or special comitions 

encountered in COMINT operations in actual practice, as 

distinguished from those of purely theoretical situations 

or principles., 

(4) Presenta.tion(s) as to AFSA's current position vii.th respect I 

to analytic .machinery- and the ideas AFSA personnel have on 

ne\.v methods and new apparatus for hiy)l-speed analysis .. 

b. He v1ent on to suegest that r~orld ~"ar II F.-operations would make an 

excellent subject for a 1-hour presentation pertinent. to phase (3) above, and 

"t'rould, moreover, be useful in providing background for wired.-Vlheel problems. 

The E-presentation should not be exhaustive and should be slanted tO\"lard laying 

the .foundat.ion f'or an understa..'lding of" the "sari tching11 principle and machinerytherefor.

c. Brief discussion then indicated the desirability or having a tour 

ot COlDJJT operations follow rather than precede the E-presentation and this 

was agreed upon. 

d. The question of the advisability or making a presentation directed 

tov1ard the solution of problems in the field of additive systems we.s discussed. 

and a1th0Uf,h some deemed it impractical and inadvisable to include such a 

presentation, because of lack of time, the nature or those problems, and the 

possibility of confusing SCAG members by' giving them too much at first, it wa~ 

finally agreed that a brief presentation thereon v1ould be useful,, it only' to 

give the members or SCAG a general picture of the problems in the additive 

field and how they lvere solved in World War II. It was aue;gested that the GEE 

problem lrould not only be very interestinp,, but highly useful. 

e. The decision to use the World Viar II E-operations as a basis for 

this presentation brought up the question of l'fl;lether reference to UK-US 

collaboration should be avoided and whether the BLO via.a to be permitted to 

learn about SCAG and the proposed conference. lJDlAFSA indicated that no 

' 

special efforts tmta.rd maintaining secrecy in this regard we1•e necesaar;r but 

that AFSA need not teke acy- acth-e steps tovrard informing the BLO as to SCAG, 

or tOlvard disclosing to SCAG full details as to UK-US collaboration. 

t. ri:r. Highley pointed out, am it 't'laS agreed, that a presentation 

regarding AFSA as an agency o£ the JCS and the Armed Forces would be useful 

for background or a general nature. This should include information regarding 

sources of raw rna·t.erial, how· it gets to AFSA, what is done with it and with 

the end product, etc. 

g. Dr. Campaigne suggested that a presentation dealing 't'l'i.th the 

mathematical analysis of 1rl.red-wheel problems would be very use:ful as background for SCAG in studying IW.batross; he suggested Jf.r • .Albert E. Roberts of 

F.RA as nost co~petent to rr.a.ke this presentation, since he is most familiar 

\'Tith task S""J':,~T.r.R. 

h. Dr. Campaigne also sup-,gested that a lresentation be ma.de regardine AFSAts proeram in the computer .field and that this program be reviewed by 

SCAG. 

i. It was proposed that as the final item on the program a list. of 

problems in the solution of l'rhich SCAG might assist AFSA be rJ.ra.vm up and 

discussed.

6. a. It was agreed that the first conference of SCAG should consume 

approximately three full da,vs and that it should be primarily arranged ror 

and directed tov1ard. briefing the mathematical members or SCAG since it was 

true, aa pointed. out by LCDR Hall, that most of the engineering members 

already have a good lmowledge of the background of C01'D?T and the subjects 

to be discussed.. 

b. A tentative agenda for this conference, based upon the items 

mentioned in Par. 5 above, is attached hereto(Enclosure A). 

1. a. lJIRAFSA indicated his desire to have everythine ready for a 

first meeting of SC.\G on or about l lfay 1951, and it was the ooncensus that 

11dry runs" o£ presentations were essential and should be made well in advance 

of the opening session so ae to make the actual presentations suitable £or 

the distinguished audience before which they will be p,iven. 

b. DJRAFSA indicated that he r1ould try to have certain important 

officers welcome SCAG at the openine session, such as the Director, Central 

T.ntelligence and one or more or the Service Directors ot Intelligence. 

S. a. l.CDR Gleason volunteered to prepare the presentation on 

E-operationa and ~fr. Kirby agi'eed to prepare that on additive problems; both 

agreed to be ready for Rdry runs" on or about 16 April. 

b. These presentations are to be brier, touch only the high spots, 

and be slanted so as to have an immediate bearing on the specific problems 

_to be studied by SCAG. Exhibits will be used to illustrate points or specia1 

9. a. It was suggested that the ASA Conference Room (AHS) and Roan 

20202 at MSS would be most suitable for the general sessions, and steps will 

be taken to reserve them tor this purpose. 

b. T)!RAFSA suggested that ror the duration or the conference each 

flEmlher of SCAG be assigned a specific member of ~SA to serve as a guide and 

assistant to the SCAG member to whom. assigned, such assignments to be made on 

the basis of community of interests. 

e. "PV11 badges will be provided the members or SCAG and all steps 

ta.ken to facilitate their entry- and extt. 

d. DIRAFSA is to look into the matter of social arrangements ar:d. 

possible entertainment for the conference.
