Lugar is in Russia with Sen. Barack Obama (D-Ill.) to visit several sites associated with the program. They are scheduled to visit a nuclear warhead storage facility in Saratov, 450 miles south of Moscow, and a site near Perm, about 725 miles east of the Russian capital, where mobile SS-24 and SS-25 intercontinental ballistic missiles that once threatened the United States are being destroyed.
On previous visits, Lugar said, he has run into situations where Americans were denied access to U.S.-funded activities.
"There might be a commander who is just uncooperative, who wasn't really eager to see Americans around there," Lugar said. "So we had to argue diplomatically that, after all, this was cooperative, we were providing contractors and various other support, so we felt that for the American taxpayers we ought to take a look. This was not always agreed to in the old days or more recent days."
Lugar recalled visiting a Russian warhead storage facility about five years ago.
"Literally we saw the warheads sort of like coffins, lying side by side, with labels at the top indicating ... when the warhead was constructed, what kind of servicing, how long it might have efficacy," he said.
Lugar said he believed it was important for the momentum of the program to continue the work, citing as an example U.S. help in construction of a plant in the Siberian town of Shchuchye to destroy chemical weapons.
"We believe it's in our best interests to continue to work with the Russians and other countries to fund the Shchuchye project, which I understand will finally be completed in about 2008, because there's still 40,000 metric tons of nerve gas or other dangerous chemical weapons out there that Russia has pledged to destroy but physically found it's unable to do so by itself," he said.
On Friday, Lugar and Obama visited a Moscow-area agricultural laboratory where Soviet-era research included finding ways to counter a possible U.S. biological weapons attack.
"This is a biological facility dealing with agricultural situations, and there are dangerous pathogens. They're scattered over many rooms, many floors, many buildings," Lugar said. "So the idea, which the Russians fully support and are enthusiastic about, is that we rebuild a certain section or fortify these rooms so they will contain in a fairly small area the pathogens, and thus secure the place."
