MEMORANDUM FOR: Special Assistant to the Director
for Planning and Development
SUBJECT : Advisory Panel Meeting
1. Af ter he=i the results o design studies 25X1
and those o I believe that three issues will have to be re- 25X1
solved at the next meeting of the Advisory Panel on 12 November 1958.
The first of these is the question of a relative radar detectability of
the two designs. Both contractors have had the benefit off- 25X1
advice and model testing. I am discussing with Frank the possibility
that he get the best estimates of both contractors and incorporate them
in his Monte Carlo type analysis for presentation to the Advisory Panel.
2. The second issue involves a number of factors including the re-
lative aerodynamic performances. the addition heating problems which
might be encountered at and the area which can 25X1
be covered with certain design ranges o THE reconnaissance vehicle util-
izing staging or refueling. In this area we will have to rely, I suspect,
on the knowledge and forthrightness of the contractors plus our own exam-
ination of the best target geometry.
3. The third issue is that of the relative complexity, reliability
and times to develop ramjets which operate on the one hand in a speed
regime of Mach 2 to Mach 4 and on the other hand over a speed range of
high supersonic to about Mach 3. On the last point we should perhaps con-
sider inviting to attend the meeting on 25X1
12 November. However, this would add, undesirably, no doubt, to the pre-
sentation time. As an alternative, but somewhat less satisfactory than
having them present to answer directly questions from the Panel, we could
discuss this last area privately with people from Ion 25X1
their home ground prior to the meeting on 12 November.
4. I have informedi of the discouraging results of the25X1
J-79 powered F-101 using BEF fuel. Key told me in turn that while he
was unaware of the F-101 test with its discouraging results from the radar
