The Russian Navy will resume Bulava test launches in August or September, according to a navy official.

The official said that three test launches would be carried out for the ill-fated Bulava ballistic missile by the end of 2010, according to RIA Novosti.

The latest test launch of Bulava on 9 December 2009 from the Dmitry Donskoy nuclear submarine in the White Sea failed due to an engine malfunction.

Bulava is a three-stage liquid and solid-propellant submarine-launched ballistic missile that was successfully launched for only five times in 12 tests.

The Russian Navy intends to fit the Bulava ballistic missiles on its Borey Class submarines once they are operational with the navy.
