From today's Albuquerque Journal:

Tired of nuclear weapons that behave like finicky Ferraris, a small group of nuclear weapons designers is beginning to think about an alternative. Think Volkswagen Bug— nothing flashy, just cheap and reliable.

The program, created under prodding from Congress and the Pentagon, is modest in size, just small teams of designers at nuclear weapons labs in New Mexico and California. But if it succeeds, it could lead to a new generation of nuclear weapons fundamentally different from the finely tuned, lightweight killers designed for the Cold War.
