LAS VEGAS — A major nuclear weapons test was conducted Saturday deep beneath the surface of the Nevada Test Site, the Department of Energy announced.
The test, which had a yield of between 20 and 150 kilotons, was detonated 1,690 feet beneath Yucca Flat, about 87 miles northwest of Las Vegas, department spokesman Chris West said.
The blast, code-named "Cottage," was only the second announced test of the year at the sprawling testing facility. The last was March 15, when a weapon was detonated a few miles away from Saturday's test site.
First in Three Months
The two recent tests ended a three-month span when no announced tests were detonated at the site, the longest pause in testing since late 1976 and early 1977 when four months elapsed between tests.
