MOSCOW, June 20 (RIA Novosti) - Russia will conduct scheduled flight tests of the Bulava sea-launched ballistic missile in the next two months, a deputy defense minister said Tuesday.

"This test will involve target destruction at a testing site, like previous, fourth, test," Army General Alexei Moskovsky said, adding that the upcoming test would be more demanding.

Four previous tests clearly showed that the development and testing of the missile were in the final stages, the general said.

The R-30 Bulava (SS-NX-30) ballistic missile has been developed at the Moscow Institute of Thermal Technology.

The first in-flight test launch was conducted on September 27, 2005, from the Dmitry Donskoi, a Typhoon-class ballistic missile submarine.

On December 21, 2005 another Bulava was launched from the Dmitry Donskoi in the White Sea before traveling thousands of miles to hit a dummy target on the Kura test site on the Kamchatka Peninsula. It was the first time a Bulava had been launched from a submerged position.

Russia's Borey-class nuclear submarines could be equipped with Bulava missiles as early as in 2008, the missile's chief designer said in April.
