Ten Soviet inspectors arrived at Dugway Proving Ground on Tuesday for a surprise check, designed to make sure that America wasn't secretly testing cruise missiles capable of delivering nuclear weapons.

The team arrived about 2 p.m., had dinner with Dugway officers about 7 p.m., and completed its inspection later in the day, Dick Whitaker, public affairs officer at Dugway, said Wednesday.The inspection was carried out near Wig Mountain, where a cruise-missile testing range had operated. The range has been shut down, under the Intermediate Nuclear Forces Treaty of 1988, and the Soviets were making certain that it was not secretly reactivated.

Under the treaty, they may inspect Dugway Proving Ground on short notice for the next 12 years to make sure that the missiles aren't being tested.

The inspectors were separate from a group of Soviets permanently stationed near the Hercules facility at Magna, who are there to make sure that missiles aren't manufactured in contravention of the treaty. America has similar teams and also carries out surprise inspections in the Soviet Union.

For surprise inspections, the Soviets do not say where they are going until they arrive at Travis Air Force Base, Calif. They could fly to any of several inspection sites in the country.

The inspection went off without a hitch.
