'Mr, Strauss recalled the President's instructions to the AEC"~

to reduce, 1f picvsivie, the number of shots scheduled for Operation
HARDTACK to less than 25,

He said the Commission wished to ciscuss

with the MLC the schedule for the test serles and attempt to
eliminate some o* the shots.

General St:iroird then reviewed with

the aid of charts the 18 devices scheduled by the AEC, and the 3
contingency devices which arc to be ready for testing if some of
the other shots do not function properly,
Colonel Lay described with the use of slides the five shots
requested by the DOD for the test series,

‘Three of the five, he

said, would be high altitude detonations and the other two WenaGbe underwater bursts designed“for naval use,

The highsedbuag:
LR, |
shots to be detonated from rockets, Colonel Lay said, are int nded

to provide information in three major categories; (1) weapons =
effects data for anti-ICBM missiles

(2)

data on neutron fluxes at

high altitudes, and (3) the ability to detect nuclear detonations

whether it would be possible to obtain all the information needed
from the 250,000 foot shot alone,

He pointed out that off-site

fallout would be reduced by approximately two megatons if the
125,000 foot shot were eliminated,
General Loper replied that in order to determine the effects
of detonations at these high altitudes it is necessary to know
