America’s intercontinental ballistic missile force is fading. 400 Minuteman IIIs — the remnant of a fleet deployed in the 1970s — will by mid-decade need too much maintenance to threaten the largest strikes contemplated by deterrence strategists. Refurbishing these aging missiles would cost more than replacing them, so the Air Force has given Northrop Grumman a $13.3 billion contract for the Ground Based Strategic Deterrent, a new ICBM that might cost nearly $100 billion.
