(Washington Reuters) The U.S. Department of Defense said on Tuesday (5th) that the U.S. Navy has been equipped with a submarine ballistic missile with a low -equivalent nuclear warhead.The Pentagon believes that the United States needs such arms to deal with the threats of Russia.

The U.S. Department of Defense said in a statement that day that the U.S. Navy has been equipped with W76-2 low-volume nuclear warheads on the submarine ballistic missile.The statement stated that it enhanced the deterrence of the United States, reflected the United States' commitment to extending deterrence, and showed to potential opponents that limited nuclear deployment had no advantage.

According to the statement, in the nuclear situation assessment released by the US Department of Defense in 2018, the potential opponent in the United States feels that deployment of low equivalent nuclear weapons can bring advantages to the United States and its allies. In response, the U.S. military must improve some submarine shootingThe ballistic missile can be equipped with a low -equivalent nuclear warhead.

The power of the explosion is like the original bullets voted in the U.S. World War II

This low -volume nuclear warhead is still devastating, but its lethality is less than 20,000 tons. The explosion is about the same as the atomic bomb cast by the United States in the U.S. in Japan during World War II.

U.S. arms control advocates and some legislators believe that this low -volume weapon reduces the threshold of might use nuclear weapons and may increase the possibility of nuclear conflict.

At present, the United States already has low -yield nuclear weapons launched in the United States, and some experts believe that this should be enough.
