Effects input and structural response information of two FuJ=4 aircraft
was measured.
‘The information obtained was concentrated in inputs and effe-t,
from higher yields in order to correlate with data obtained from the lover
yields of Plumbbob and confirm the Class D delivery capability of the eircrai+
In general, excellent correletion of blast response data was obtained, vei -fying the dynamic analysis used for predicting structural responses,
It tas
concluded that response data had been obtained over a sufficiently wice rouge
of yields and incidence angles to permit subsequent definition of the Clacs ~~
delivery capability of the Fu-4B aircraft.

This prcegram, consisting of five projects had a wide range of project’
station locations:
Wake Island and Eniwetok, Eikini, Kwajalein, Kusaic,. °
Wotho, and Rorgelap atolls.
One project to study the wave form of electromagnetic pulse from a
muclear detonation, used two sites:
Wotho, 240 miles from Eniwetok,
Kusaie, 420 miles from Eniwetok, and
The objective was to make broad-band measure.-
ments from 0 to 10 Mc at ranges up to 460 miles.

Although improvements in equipment were in-
corporated, the pimary conecrn of this project wes to increase the catalog-
ing of wave forms.

The data, which is in good agreeneit with thet obtained during Operation
Redwing, indiccles that device yield and range and the presence of 2 second
stage can be determined from wave-form parameters.
Another project with stations ct ‘ishi Island and Kusaie studied iono=-
spheric effects of large~yield surface detonations,.
Inagreement with reswts
of Operation Redwing Project 6.3, the energy responsible for the first disturbance in the ionosphere above Kusaie was propegated with a mean volocity
of 20 km/min,
Also corroborating previous results, the second disturbance
