December 19,2008:
Despite several successful tests in the last two years, and the decision to
put its new Bulava SLBMs (Sea Launched Ballistic Missiles) into production,
Russia just announced that several more tests would be performed before the
missile was actually put into service.
Despite the
many test failures, the Russians were confident in the basic technology in the
Bulava. They knew there would be test failures, and believed they were facing
no more problems that the two most recent U.S. SLBMs. These had had a 13
percent (23 tests of the Trident I) and two percent (49 tests of Trident II)
failure rate. What did make many Russians nervous was the fact that the Bulava
is replacement for an earlier SLBM that had to be cancelled during development
because of too many test failures, and too many design and equipment problems
that could not be fixed. Thus the Bulava is basically a navalized version of
the successful Topol land based ICBM. The reliability of the Topol is the
primary reason the Russians moved forward with Bulava.
The Bulava
will equip the new Borei class SSBN (nuclear powered ballistic missile
submarine). The first one is about ready to enter service. The Borei class
boats would replace the aging Cold War era SSBNs, which are being retired
because of safety and reliability issues and the high expense of running them.
Nuclear submarines are one area of military spending that did not get cut back
sharply after the Soviet Union collapsed in 1991.
The 45 ton
Bulava SLBM is a little shorter than the Topol M, so that it could fit into the
missile tube on the sub. Thus Bulava has a shorter range of some 8,000
kilometers. Bulava has three stages and uses solid fuel. Currently, each Bulava
is being configured to carry ten 150 kiloton warheads. The warhead is also
shielded to provide protection from the electronic pulse of nearby nuclear
explosions. The Bulava could also carry one 500 kiloton nuclear warhead, plus
decoys. Many Russians are obsessed with trying to defeat American anti-missile systems.
Russian
doubts about Bulava are consistent with long time problems with their submarine
launched ballistic missiles. These problems were largely kept secret during the
Cold War, but since then, more information has emerged. Apparently the Russians
want to increase the reliability of the Bulava before they make lots of them
for arming the new Borei boats. This may delay deployment of the first Borei
boat by a year or more.
