that;
propose .
Ambassador Johnson reviewed the proposal and concluded that
neither State have. need for the additional communications
is not clear -- according to Ambassador Johnson review.
He concludes that the only essential requirement which the system
will serve is secure voice for tactical air control comrxiunications
between the centers in Phnom Penh and Saigon ?- the volume of
the tra#?ic and need fax secure voice (as contrasted with teletype)
Ambassador Johnson is expected to recommend to Adxx~.iral Mooxer
--. The present control center (in downtown Ph~.om Penh where
electrical interference is high) be moved to a mare suli.table
location.
-- Provide voice codes for use by Fhnom Penh and Saigon centers.
-- .Data on traffic volume and need for secure voice be compiled as
basis for reevaluation o? the proposal. (He requested -- see below. )
-- Steps be taken to provide Embassy Phnom Penh telephone circuit
with secure voice equipxxient.
Ambassador Johnson sent a cable yesterday asking for additional
information traffic volume on which to base his reccammendation to you.

From the foregoing it is clear that the principal justification for the
trapo-scatter system is tactical aix control. The traffic now may be
comparatively light (we just don't know). But with increasing Thai and
SVN aix support and U. S. "interdiction" efforts, the traffic may increase
substantially. Moxeaver MACV is convinced that no "voice codes" will
be secuxe for long.
-- It would provide rapid and secure voice camxx~.unications between
the .D i r.e c.t, Aix Support Center, in Phnom Penh, and the Tactical
Air ,Control Center in Saigon (and latex Bangkok).
-- It vsrauld provide secure telephonic camxnunications between Phnom
Penh and Washington/Saigon.
-- It would provide a support fax SSO communications of a hi her
quality and ca acit ca abilit
-The decision, therefore, rests primarily on the need fox better
tactical aix control. Ambassador Johnson has requested an estimate of
the volume of this traffic (a reply is expected today). We would guess
that any reply will be a highly qualified one' -- there are just. too many
variables fox' a firxin projection of future .traffic of this kind.
The advantages of this system would be:
-- It would provide roam for expansion if necessary.
The disadvantages would be a larger number of personnel in Phnom.
Penh. -- at least ten contract ox other U. S. civilian personnel -- increased
U. S, visibility at Phnom Penh Airport -- four large vans and an antenna
tower, requiring security protection. There is at present no secuxe commu-
nication between the airport and the Embassy in Phnom. Penh -- this could
be provided.
We recommend that we wait until the reply to Ambassador Johnson's
query to the field is received today. ,Then, unless the predicted traffic
volume for tactical air control is at ~. 1ow level, we recommend imxx~.ediate
approval of the project. .
