Moscow, Nov 1 (IANS/RIA Novosti): Russia is strengthening the security of its missile launching sites in the wake of rising potential threats.

The Russian Strategic Missile Forces (SMF) are finalising the modernisation of automated security systems at nine of its major missile bases, said SMF spokesperson Col. Vadim Koval Wednesday.

The step is being undertaken to counter the growing threat of potential terrorist attacks, he added.

"The modernisation includes the upgrade of warning and surveillance systems, detection sensors, integrated fire control systems and power supply grids," the spokesperson said.

He also said that automated security at SMF bases is provided by six different systems, developed and produced by Russian defence industry firms.

"The overhaul is being carried out at the highest levels of secrecy in regard to the specifications of the installed equipment and its operating algorithms," Koval said.

The SMF is also tightening rules of engagement and training requirements for security personnel at the bases and around mobile missile launch sites.
