Declassified and approved for release by NSA on 03-12-2014 pursuant to E.O. 1352e 
bo In August 1951 the Report of the Tripart~ .. :e Working Grotw was 

approved by the US. As of this date neither the UK I .... ________ J 

Govemm.ent hae approved that Report o However, it i!s to be noted that 

despite the conclusion quoted above in sub=paragraph _a, the pertinent re~om~ 

mendation based upon that conclusion simply states that: (U3CIB~ Ll,1./l32 9 4b) 

"bo The proposed approach and plan be implemented when 

LSIB and USCIB have agreed that the requisite conditions 

have been meto 11 

Co It appears, therefore, that the recommendation of th~ I 

Conferees does not require that the approach to the I I be contingent 

upon the approval of the Report of the Tripartite Working Group by all 

three ;·. ernmentso Hence, it USCIB agrees wit·····h LS ..... /IB' the a ... p .. iproach to the I Jcould be made without further delayo 

6,. With reference to the CCM 1 s to be provided,, the lJK, as noted above, 

will be ready 1n about two months to provide its quota (8) of the twenty 

machines 1niti~ required tor thel j;i the US/agreed to furnish 

the remaining twelve,. At the time of the Conference, the A.nI\Y agreed to 

provide these twelve machines and it is assumed that/this promise is still 

valid o Sixty additional machines are to be provideQ. by the US and the UK "in a 

program phased in consonance with their respeciive/.NATO commf,tments.,"
