Mark 21 nuclear bomb
The Mark 21 nuclear bomb was a United States nuclear gravity bomb first produced in 1955. It was based on the TX-21 "Shrimp" prototype that had been detonated during the Castle Bravo test in March 1954. While most of the Operation Castle tests were intended to evaluate weapons intended for immediate stockpile, or which were already available for use as part of the Emergency Capability Program, Castle Bravo was intended to test a design which would drastically reduce the size and costs of the first generation of air-droppable atomic weapons (the Mk 14, Mk 17 & Mk 24). At long, in diameter, and weighing , the Mk-21 was half the length and one-third the weight of the Mk-17/24 weapons it replaced. Its minimum yield was specified at four megatons.
The Bravo
The Bravo is a novel by James Fenimore Cooper first published in 1831 in three volumes. Inspired by a trip to Europe where he traveled through much of Italy, the novel is set in Venice. "The Bravo" is the first of Cooper's three novels to be set in Europe. This group of three novels, which one critic would call Cooper's "European trilogy", include "The Heidenmauer" and "". Like his other novels set in Europe, "The Bravo" was not very well received in the United States. The book largely focuses on political themes, especially the tension between the social elite and other classes.
