A huge mushroom cloud of dust is expected to rise over Nevada's desert in June when the Pentagon plans to detonate a gigantic, 700-ton explosive -- the biggest open-air chemical blast ever at the Nevada Test Site -- as part of the research into developing weapons that can destroy deeply buried military targets, officials said yesterday.

The test, code-named "Divine Strake," will occur on June 2 about 90 miles northwest of Las Vegas in a high desert valley bounded by mountains, according to Pentagon and Energy Department officials.

"This is the largest single explosive we could imagine doing," said James A. Tegnelia, director of the Pentagon's Defense Threat Reduction Agency, which is conducting the test.
