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.
Dwayne Bravo
Bravo made his One Day International debut against England in their 2003/04 tour of the Caribbean, in a match in which he failed to bat but took 2–31 with the ball. In the West Indies tour of England in 2004 Bravo made his Test debut when he was selected for the First Test at Lord's in which he scored 44 and 10 and took three wickets. He finished the Test series with 68 wickets and a total of 220 runs with his most impressive performance at Old Trafford in a match in which he was the top scorer in the first innings with 77 followed by an 8 for 37 performance with the ball. The latter remains his best bowling figures in Test cricket.
