When was the Castle Bravo test performed?
Castle Bravo
Castle Bravo was the first in a series of high-yield thermonuclear weapon design tests conducted by the United States at Bikini Atoll, Marshall Islands, as part of Operation Castle. Detonated on March 1, 1954, the device was the most powerful nuclear device detonated by the United States and its first lithium deuteride fueled thermonuclear weapon.[1][2] Castle Bravo's yield was 15 megatons of TNT, 2.5 times the predicted 6.0 megatons, due to unforeseen additional reactions involving 7Li,[3] which led to the unexpected radioactive contamination of areas to the east of Bikini Atoll.
Castlemore Moat
The motte and bailey castle was constructed in the 12th century AD by Raymond FitzGerald (Raymond le Gros), one of the commanders of the Norman invasion of Ireland. The land of Forth O'Nolan was granted to Raymond and he married Basilia, sister of Strongbow. They lived together at Castlemore.
