Kommersant reports today that the test of the Bulava missile, which took place on September 18, 2008, was not quite successful. According to the Kommersant report, all three stages of the missile performed well, but then the bus failed to separate the warheads. It was the eighth test of the missile (not including two pop-up tests). The success record is hard to judge, but it appears that if we count this test as a partial success, four of the eight flight tests were successful or partially successful so far.
