STATUS
AEC "code" words for future test oper-
ations.
It is considered that only
association of the “code” word with
time (See 1.1) is revealing and not
its identification as a test operation.
Hence the operation "code" word is a
code word in situations revealing the
timing of a test series, but is a
nickname for ali other references.
1.2.1
Hardtack or OQnoeration Hardtack
when used as a "nickname" (1.e.,
in any context nct revealing
time).
EXAMPLE:
U
The mere association
JTP-7 with Hardtack
or Operation Hardtack
but without indication
of ~iming is not a re-
vealing context.
1.2.2
A code word such as Hardtack or
Operation Hardtack used in any
context which reveals the tine
of a miclear test operation.
(See 1.1).
NOTE:
NRD
The intent of the use of
"code" words is to permit
™
unclassified reference to
.
operation with the under-
i
c
q
a forthcoming nuclear test
a
standing that such reference
a
of iteelf does not provide:
Qajas
t that a
potent
test operation will be held at 2S
or EPG or (2) a statement
that a nuclear teat operation will be held during
some definite period of time
(See 1.1)
