COMINT Relations withl ... .,.__ _ __. 

The CHAIRMAN (Captain Taylor) stated that the special meeting was · called to consider the enclosure with USCIB 29.17/16 of 15February 1955, 

which comprised the U.K. response to the recent query concerning (a) which 

of the equipments listed in LSIB 28/55 the U.K. believe to be intended 

which 

for ELINT 

may be 

purposes 

used for 

and

are 

and

COMINT, 

for 

how

the 

purposes, 

U.K. believes 

and ~ 

intends to use them and what COMINT th.e U.K. expe.cts may be thus 01:5 aine • 

He invited comment from the Chairman o.f. t· .. he U.S. T~ Committee which 

has considered the list of equipment requested forL___J. 

CAPl'AIN HOLTWICK suggested that the\U.K. response be reviewed item 

by item, considering at the same time the comments of the members of the 

Technical Committee. 

It was so agreed. 

Referring to paragraph A of the U.K. response, LT. COLONEL HARROLD 

expressed some doubt as to the requirement \for ten AN/APR-9 1s to ensure 

continuous operation of six. He explained that this equipment is in 

critical short supply; however, through careful planning, he said, the 

Air Force has been able to progrfm ±.tern Ar· /Af'R· ... -9's with all necessary backup equipment for delivery to ___ .... 

CCMMANDER BRINGLE responded that the Navy has found it possible to 

keep fourteen to sixteen AN/APR-9 1s in operation with the assistance of 

only two spares. 

In reply to the Technical Commit tee 1 s comment that such equipment 

could in some instances be used for VHF and u~ sear~r,, LT. COLONEL 

HARROLD said that he does not oppose providing with equipment for 

VHF or UHF search; however,, he does not feel that the AN/APR-9 is the 

best equipment to accomplish this objective and would be more properly 

classified as purely EI.INT equipment. 

CAPTAIN HOLTWICK said that although ELINT is outside of USCIB1s 

area of responsibility, it seems necessary at times, that the Board take 

notice of it. It is not,, he noted, a question of whether the equipment 

is to be used for COMINT or ELINT purposes, but a simple recognition of 

the fact that USCIB cannot take a position on an ELINT transaction.

LT. COLONEL HARROLD explained the operating principle of the 

AN/APR-9 concluding with his opinion that other equipment would better 

serve the intended purpose. 

Continuation of the review .of the U.K. response in conjunction with 

the opinion of the U.S. Technical Committee resulted in agreement that 

USCIB should undertake to supply all items except those listed in 

paragraphs 3(a) and 3(c) ot the enclosure with USCIB ';fJ.17/13 of 

31 January 1955. It was concluded that the items in paragraphs 3(a) and 

3(c) appear tr he nymarily of an ELINT nature; are probably not intended 

to be used by for COMINT purposes, and are in critical short 

supply. With respect to offering substitute equipment for unavailable 

CCMINT items or for those considered obsolete, the members generally 

agreed that a frank exposition of the U.S. position should be provided 

and suitable substitutes offered. 

The CHAIRMAN, at this point, suggested that a-drafting committee 

be appointed to explore further the availability of the equipment under 

discussion and to prepare a message to LSIB presenting the current U.S. 

position. 

It was so agreed, with the understanding that the drafting committee 

would prepare, for USCIBEC approval, a message to be sent to LSIB by USCIB 

presenting the current U.S. position, the message to be drafted in such 

a form as to make it easy to separate policy statements from statements 

simply setting forth what equipment can and cannot be provided. 

DECISION: (16 February 1955). As a result of the USCIBEC discussion, it 

was agreed that: 

a. The AN/APR-9 equipments listed in item 3(a) of USCIB 29.17/13 

of 31 January 1955, are primarily ELINT bu~ do have limited COMINT uses. 

They are currently in critical short supply in the U.S. and those that are 

available are being monopolized as a high priority item in the ELINT 

effort. 

b. The SKL chain amplifiers listed in item 3(b) of USCIB ';fJ.17/13 

may be used for either ELINT or CCMINT, principally the latter. They are 

an unclassified item available commercially. 

c. The Signal Generators listed in item 3(c) fall in the same 

category as the AN/APR-9 Receivers listed in item 3(a). They are in fact 

test devices for maintenance of the AN/APR-9 Receiver. 

d. The Kay Sonograph (item 3(d)) is a commercial item used extensively for either ELINT or COMINT purposes.

e. The Clark VHF Receivers listed in item '.3(e) are used extensively !or both ELINT and COl-!IINT. They can be made available, but not 

immediately. 

t. The SCR-2!Jl HF /DF equipments listed in item 3(.f) are solely 

C<lUNT items and are now considered obsolete in the U.S. They are also 

unavailable. More modern equipment, such as the AN/CRD-2A, is understood 

to be available. 

In addition, USCIBEC agreed that: 

a. USCIB should not undertake to try to supply any of the items 

listed in paragraphs 3(a) and 3(c) of USCIB 29.17/13. · 

b. USCIB should be as frank as possible with LSIB on this 

matter. 

c. Captain Taylor, Captain Holtwick and Lt. Colonel Harrold 

would meet at 0900, Thursday, 17 February 1955, to explore further the 

availability of the equipment and to draft a message .tor approval by 

USCIBEC to be sent to LSIB by USCIB as presenting the current U.S. position. 

The meeting adjourned at 1130.
