0800039 - Project Long Shot - 1965 - 13:15 - Black&White - This video discusses Project LONG SHOT, a Department of Defense, Defense Atomic Support Agency- sponsored test, with participation of the Atomic Energy Commission, the Department of the Interior, the U.S. Coast and Geodetic Survey, and numerous university scientists and engineers.

The approximately 80-kiloton LONG SHOT device, buried 2300 feet underground, was detonated on October 29, 1965. As part of the Vela Uniform Program, LONG SHOTs primary purpose was to find ways to detect nuclear explosions underground using ground-based seismic instruments.

This video discusses geological studies conducted on the island prior to the detonation; test preparations including construction milestones; an overview of experiments conducted during the project; and environmental and safety activities before and after the test. The canister holding the nuclear explosive is shown being lowered into the shaft. Surface effects during and after the detonation are also shown.

The three underground nuclear tests conducted on Amchitka Island, Alaska, were as follows:

LONG SHOT, October 29, 1965, shaft, Vela Uniform Project, approximately 80 kilotons
MILROW October 2, 1969, shaft, weapons related, approximately 1 megaton (Mt)
CANNIKIN, November 6, 1971, shaft, weapons related, less than 5 Mt
