A Russian Soyuz-2.1b carrier rocket laden with the newest defense satellite was launched from the Plesetsk Cosmodrome in the country’s northwest, the Russian Defense Ministry said Tuesday.

“A Soyuz-2.1b carrier rocket with a new generation space apparatus in the interests of the Russian Defense Ministry was launched from the Aerospace Forces’ Plesetsk Cosmodrome at 9:34 a.m. [06:34 GMT],” the Defense Ministry’s press service said.

The current launch is the fourth in 2015 from the Plesetsk Cosmodrome using a Soyuz-2 carrier rocket.

Furthermore, Russia’s Frigate rocket booster carrying a state-of-the-art Defense Ministry satellite successfully separated from its Soyuz-2.1b carrier rocket minutes after launch, the ministry said Tuesday.

“The spacecraft’s ascent to a calculated orbit with the help of the Frigate upper stage rocket will take several hours,” a Ministry representative told RIA Novosti.
