Two goals of these tests were to determine if radiation and blast and heat effects of high-altitudedetonations were capable of neutralizing an enemy reentry vehicle and capable of determining theblackout effects on radar and communications of various yields and altitudes of bursts.

Operation Fishbowl, the Department of Defense’s high altitude testing portion of Operation Dominic I, was conducted in the Johnston Island area of the Pacific testing area in 1962. These five weapons-effects tests, launched by Strypi, Thor, and Nike Hercules rockets, were as follows:

• STARFISH PRIME, July 9, 400-kilometer altitude, 1.4 megaton
• CHECKMATE, October 20, tens of kilometers altitude, low
• BLUEGILL 3 PRIME, October 26, tens of kilometers altitude, submegaton
• KINGFISH, November 1, tens of kilometers altitude; submegaton
• TIGHTROPE, November 4, tens of kilometers altitude, low
