Dear Dick:
In keeping with our recent conversation, I would like to propose the follow-
ing work statement and cost estimate for initial studies on project GUSTO.
On the t8th, were here to give the initial security
briefings.
During our recent meeting in the northeast. I made a certain proposal to you
and others regarding a new bird, in which you showed considerable interest.
Prior to this time we had, on our own, made studies of various materials
and combinations of structures bearing on the general effects desired for
project GUSTO. I would like to propose the following work statement for the
next phase of our activities:
1. Carry on preliminary design of the bird shown to you during our
recent visit, including studies of equipment arrangement, structure, weight,
balance, etc.
2. Undertake early wind tunnel tests in both a low speed and high speed
wind tunnel.
3. Carry on such tests as we are able to make on the effect of various
materials and shapes of the bird with regard to their reflective character-
istics.
4. Investigate various plastic structures for use in certain areas of the
bird. This includes structural testing, availability, and desirability of sub-
contracting certain construction.
'v'arious reports will be prepared on the outcome of the above investigations,
and certain material has already been furnished you. I would not expect
that we could complete high speed tests in the wind tunnel by June 1958,
although we should be well into a model construction at that time. Lcw speed
wind tunnel tests should be completed by that time.
25X1 A A sum of is proposed for your acceptance to cover the total cost
of the activity indicated above. It is extremely difficult to estimate accurately
at this time the specific breakdown of this cost proposal, because of
important unknowns in the basic field of Rainbow. The above sum would ccvc r
our early studies, two reports on which have already been given you on
alternative configurations which might be applicable to project GUSTO. We
are continuing our studies on the assumption that the foregoing outline is

to you but, as in all our past dealings. various changes in the
program can certainly be ride by mutual agreement, as further knowledge
is gained.
The above cost does not include the major mockups discussed in our
northeast meeting recently, as yon are aware.
Sincerely,
Approved For Release 2001/03/01 : CIA-RDP33-02415A000500390144-4
