Yesterday workers in Amarillo, Texas removed the uranium from the last B53 nuclear bomb. This marks a huge moment for this country because the B53 were the largest nuclear bombs ever created by the United States. The B53 which is the size of a minivan weighed in at around 5 tons and was 600 times more powerful then the atomic bomb that killed 140,000 people in Hiroshima, Japan. The size was due to the inaccuracies of older nuclear bomb, newer bombs are smaller but they are also better aimed to reduce collateral damage.
While the nuclear bomb was one of the most deadly technological advances of all time the science behind it cannot be ignored. Before nuclear bombs were created near the end of World War II nuclear reactions were completely unknown to the world. Through the development of nuclear bombs like the B53 we have been able to harness the power of nuclear reactions for electricity which releases less pollution then standard coal-fired power plants.
The dismantling of the bomb is part of the United States larger effort to reduce and possibly eliminate all nuclear weapons throughout the world. The two countries with the largest stockpiles of nuclear weapons, the United States and Russia, built most of them during the arm race that was the Cold War. The rest of the countries that have nuclear weapons recieved the technology from one of the original two countries. The UN has been trying to reduce the number of nuclear weapons and hopefully the START treaty that the US and Russia signed will lead these countries to reduce their nuclear stockpile as well.
