EXECUTIVE SECRETARY 

SUSLO, LONDON 

DIRNSA 

PLEASE PASS THE FOLLOWING·TO THE CHA!RMAN, LSIB FROM THE CHAIRMAN, USCIB: 

1. USCIB has carefully considered the list of equipments contained in 

your Secretary's note of 21 January 1955 (LSIB/28/55) and has asked that 

the comments set .forth below be conveyed to your Board. 

2. USCIB is prepared to provide items 3(B), (D) and (E) as listed. 

Item 3(E) is, however, not currently on hand. The Director, NSA has been 

directed to arrange for procurement and delivery of these items and will, 

if it is agreeable to you, handle the matter directly with the Director, 

GCHQ. 

3. Item (F), the SCR-291 HF /f/JF equipments, is unavailable and is, as you 

are no doubt aware, considered by our people to be obsolete. Was there a 

particular reason whyr----1 requested this? We believe we could obtain 

AN/CRD-2A 1 s !or them tr'a:'ccePtable in place of the SCR-291. 

4. Items 3(A) and 3(0), the AN/APR 9 receivers and the signal generators, 

are in critical short supply and their use has been for all practical 

purposes pre-empted as ~ high priority item for current EI.INT requirements. 

USCIB therefore cannot undertake to supply those items.

5. However, to the ext:.ent that ELINT equipment neede.d !or COMINT search 

is involved in Item .3(A) of your list, USCIB can obtain for you a limited 

quantity of AN/APR-4 equipments (or its U.S./Navy shipborne counterpart 

the RDO and SPR-2) as more suitable for UHF /communications search, if 

they are necessary to successfu;t. COMINT negotiations, even though these 

are also in short supply. 

6. While we wish to do everything possible to prevent any disruption of 

UKUSA COMINT negotiations with the I I, we must •again point out that 

USCIB has no cognizance in the ELINT field. USCIB,theref'ore is not in 

position to divert EI.INT equipment from U.S. ELINT use or to arrange 

_discontinuance of direct U.S. approaches tol Ion ELINT matters. 

7. USCIB is informed that t~/already has ;ell advayced arrangements 

to supply ELINT equipment tol___J in retum fo:tf _ ELINT and that 

GCHQ is aware of these arrangements which commenced in the spring of 1954 

and are continuing. 

S. Your comments would be appreciated." 

Meeting adjourned at 1810.
