The best of physics, of metallurgy, of electronics. During the months after the historic definition, preparations for a new series of tests to solve the problems of a deliverable megaton weapon went ahead at an accelerated pace throughout the country. Operation castle became a reality and is now successfully concluded. The report which follows is a summation of what occurred at the Pacific Proving grounds during that operation in 1954. Here the League Office record is general clarkson, task force commander. Operation castle was concluded on the 14th of may in 1954. Castle was an all thermonuclear test, a test of devices in the megaton range. We feel that the report of this important test should give the failures as well as the successes, should reflect the changes in thinking that occurred during the test. We hope this treatment will help you understand the problems that we experienced during the operation. This program encompassed them, three shots on land and 4 shots our Main Base Ca
