Russia's main arms exporter has signed a string of deals with a leading French defense firm for provision of night-vision devices on combat vehicles. The contract was signed between Russia's Rosoboronexport and France's Thales company and concerns night-vision devices for Russia's T-90 tanks that will be manufactured under a licensed agreement at an optical-mechanical plant in Vologda, Russian media reported. "Under the contract, Russia has the right to assemble thermal imaging systems for armored vehicles under license in Vologda, with the subsequent maintenance," said Igor Sevastyanov, head of the Russian defense company, according to RIA Novosti.
