Russia warns U.S. it could overwhelm N-missile shield
WASHINGTON -- Moscow warned the United States Monday that it has enough weapons to overwhelm any anti-ballistic missile system and threatened to deploy more atomic warheads if Washington builds a national missile defense system, the Washington Post reported Tuesday.
In a story from Moscow, the Post quoted Nikolai Mikhailov, first deputy defense minister, as saying that Russia's arsenal has such "technical capabilities" to "overcome" any antimissile defenses.He told the Post the technology was available and would be used if "the United States pushes us toward it."
His comments followed last week's meeting between Russian and U.S. officials to discuss possible amendments to the 1972 Anti-Ballistic Missile Treaty (ABM).
Putin Says Russia Will
'Overwhelm' US Missile Shield

MOSCOW - President Vladimir V. Putin said today that if the United States proceeded on its own to construct a missile defense shield over its territory and that of its allies, Russia would eventually upgrade its strategic nuclear arsenal with multiple warheads reversing an achievement of arms control in recent decades to ensure that it would be able to overwhelm such a shield.
Mr. Putin made his comments in a meeting with American correspondents that lasted nearly three hours tonight and was organized last week to give him an opportunity to explain his views after his summit meeting with President Bush in Slovenia on Saturday.
The Russian leader emphasized that though he is buoyed by Mr. Bush's pledge that Washington and Moscow will work cooperatively in coming months to investigate the full ramifications of Mr. Bush's vision for a new security framework that includes missile defenses, Russia is also very alert to unilateral American actions.
And in response to comments made Sunday in Washington by Mr. Bush's national security adviser, Condoleezza Rice, that the United States would proceed with missile defense with or without Russia, Mr. Putin said Russia would not threaten or try to prevent American actions, but would "augment" its nuclear forces without regard to treaties that now require the elimination of multiple warheads.

New submarine supermissile can pierce ABM shield
The new Russian liquid-fuel Liner missile is world’s most advanced submarine-based strategic weapon with range and payload capabilities surpassing every model deployed by any other country, its developer says.
The submarine-launched ballistic missile (SLBM) Liner can carry up to 12 low-yield MIRV nuclear warheads and has a payload/mass ratio surpassing any solid-fuel strategic missiles designed by the US, UK, France and China, the developer Makeyev State Rocket Center said in a statement. It is very flexible in terms of what its payload can be, varying and mixing warheads of different capabilities.
The design bureau believes that the missile, which was first tested on May 20, will ensure the use of Delta IV class submarines until at least 2030.
There are seven vessels of this class in the Russian Navy, and they are armed with the SLMBs Sineva. The Liner is a highly advanced version of the Sineva missile.
There is little further detail about the Liner’s specifications so far. Sineva is a three-stage ballistic missile. It has a reported operational range of almost 12,000 kilometers, listed throw-weigh of 2.8 tonnes and can be launched from up to 55 meters deep.
Russia is the only nation that uses liquid-fuel submarine-based nuclear missiles. All other nations deploying SLBMs opt for solid propellants, since they allow for the building of more reliable missiles, which are simpler and cheaper to operate.
Russia has a solid-fuel SLBM in development too. The Bulava missile, which is the designated armament for the advanced Borey-class submarines, has seen several delays and setbacks over the years, but now it is slated to enter service after a series of successful test fires in 2010-2011.
Military experts say there is a certain competition between the two design approaches, but each has its own niche in the Russian Navy.
“The Bulava, which is similar to the American Trident II missile, is not able to replace the heavy liquid-fuel missile Sineva and its advanced version, the Liner. Only such heavy liquid-fuel missiles are capable of throwing big payloads to very long ranges,” military analyst Igor Khokhlov told RT.
The use of such missiles is necessary due to specifics of the missions,which the Russian Navy has to carry out, as well as its structure and nature, the expert says. Historically, Russia has perceived a land invasion as the primary military threat, while the Navy’s task was to protect the coastline rather than serve as an attack force. Liquid-fuel missiles are part of this force and will remain an integral part of Russia’s nuclear deterrence for at least several decades to come.
“Submarines armed with such missiles can operate from Russia’s safe territorial waters, where they are covered by the Russian Air Force and its surface Navy. They can also have electronic equipment, necessary to suppress the US antiballistic missile system, as part of their payload in addition to the warheads themselves,” Igor Khokhlov from the Institute of World Economy and International Relations explained.
