Operation Castle was a series of high yield thermonuclear weapon design tests. The original schedule included a weaponized version of the cryogenic fuel system used in Sausage designated the TX/EC-16, the test device being named JUGHEAD. Experiment: Yankee Device: JUGHEAD Prototype: TX/EC-16 Fuel: Cryo H-3 (wet) Date: March 22, 1954 Revised Date: April 27, 1954 Predicted Yield: 8 Mt Revised Yield: 9.5 Mt Manufacturer: Los Alamos Scientific Laboratory Test Location: Barge off Iroij, Bikini
