MOSCOW, June 26 - The administration of the Pivdenmash plant in Dnipropetrovsk understands that the halt of the production of Zenit-3SL rockets may lead to the plant's shutdown, an informed source in the Russian rocket and space industry told Interfax-AVN on Wednesday.

"It is hard to predict how geopolitical processes in Ukraine may develop but one can say with a great degree of certainty that Pivdenmash is interested in the continuation of the Sea Launch project," the source noted.
