...suite are feeling better. The master's assistant says she's glad she won't have to find a pawn shop for that plutonium anklet she was on special occasions. And that gang up in D-51 is glad they don't have to take down their early-warning radar system...
Terminal defense is easiest, technologically. Warheads, heated and slowed by friction with the atmosphere on re-entry to speeds of about two miles per second, could be tracked by airborne or even ground-based radar. They could be hit by interceptor rockets or pellets discharged by fragmentation bombs. But enough missiles would have to be destroyed in boost, and enough warheads in post-boost phase or mid-course, to keep the terminal defense from being overwhelmed. And then there is the problem of hitting the warheads high enough to minimize the effect of blast, fire and radiation on the ground...
...atmosphere around the negotiating table is not likely to be improved by the Administration's determination to "get satisfaction," as one official put it, on apparent Soviet violations of past Strategic Arms Limitations Talks (SALT) treaties. One example: the construction of a huge radar facility at Krasnoyarsk in Siberia that could be used as a defensive warning system, in violation of the 1972 antiballistic missile (ABM) treaty. Richard Perle, a critic of past arms-control measures, charged last week that the U.S. has allowed the Soviets to "think they could play fast and loose with these accords...
...document envisions a "period of transition," starting around 1995, during which both sides would still have their offensive nuclear missiles. Those weapons would be protected by a latter-day version of ABMs called ballistic missile defense, or BMD. If American missiles and command centers were effectively guarded with radar-guided interceptors and death rays that could destroy incoming warheads, the Soviet Union would never be tempted to think that it could disarm and decapitate the U.S. with a pre-emptive strike. In principle, the Soviets could have a similar system...
...divulged. The secrecy has set off the inevitable guessing game over such code names as Seek Axle, Have Flag, Cactus Plant and Theme Castle. Some experts believe that Aurora is the budget heading for "stealth" technology, which one day could make a plane or cruise missile invisible to enemy radar. Aurora's price tag: $80 million in 1986 and a hefty $2.3 billion...
