Bush administration officials on Friday launched California nuclear weapons scientists on designing the nation's first H-bomb in more than 20 years.
The decision marked the biggest step yet toward a controversial plan for wholesale replacement of the fully tested U.S. nuclear arsenal with bombs and warheads of the same military missions but redesigned for greater hardiness, safety and security.
For the first "reliable, replacement warhead" — designated RRW1 — federal weapons officials chose a highly conservative design produced by a team at Lawrence Livermore and Sandia National Laboratories-California over a more free-wheeling design offered by Los Alamos lab and Sandia labs in New Mexico.
The warhead would replace the most numerous nuclear warhead in the U.S. arsenal, the W76, which rides atop missiles on submarines in the Pacific and Atlantic.
