The upcoming tests of Russia's troubled Bulava ballistic missile will determine whether it will be put in service with the Russian Navy or scrapped, a senior Navy commander said.

The Russian Navy is planning to conduct at least four test launches of the Bulava ballistic missile at the end of June.

"I believe that this summer will be decisive in terms of adopting Bulava for the service with the Navy," First Deputy of the Naval General Staff Vice Admiral Oleg Burtsev said in an interview with Ekho Moskvy radio station on Saturday.

"We will continue Bulava tests launches from Dmitry Donskoy submarine and ultimately from Borey class Yury Dolgoruky sub, which is scheduled to carry out several test launches during sea trials," Burtsev said.

The Yury Dolgoruky is the first of Russia's Borey class strategic nuclear submarines, which have been exclusively designed for the Bulava, and is currently undergoing sea trials.

The admiral confirmed that if the tests are successful, both the submarine and the missile could be put into service with the Russian Navy by the end of 2010.

The Bulava (SS-NX-30) is a three-stage liquid and solid-propellant submarine-launched ballistic missile (SLBM). It carries up to 10 MIRV warheads and has a range of over 8,000 kilometers (5,000 miles).

The future development of Bulava has been questioned by some lawmakers and defense industry officials following a series of test failures. Only five of 12 Bulava test launches from the Dmitry Donskoy sub have been officially reported as being successful.

Some analysts suggest that in reality the number of failures was considerably larger, with Russian military expert Pavel Felgenhauer contending that of the Bulava's 12 test launches, only one was entirely successful.

But the military has insisted there is no alternative to the Bulava and said the tests of the missile would continue until it is ready to enter service with the Russian Navy.
