S-400 Gets Better

Discussion Board on this DLS topic
Russia continues to develop and test new versions of its most powerful anti-aircraft missile, the S-400 (also known as the SA-20, Growler or Triumf). Particular attention is being paid to electronic countermeasures that the Americans might have, or be developing. Eighteen months ago, Russia put its first S-400a into service when a S-400 battalion (eight launchers, each with four missiles, plus a control center and radar) officially became operational outside Moscow. A second battalion was deployed in the same area this year.
Belarus is also getting the S-400 from Russia. This system is similar to the U.S. Patriot, and is expensive. Belarus is broke, but is a close ally of Russia, and will apparently get a good terms and a low price. This will also provide at least one export customer. Russia is unsure if they want to export S-400 right away, but they do want to deploy the S-400 system where it will do the most good, and pro-Russian Belarus is a good place to put the missiles.
The S-400 missiles weigh 1.8 tons each and are 26 feet long and about 20 inches in diameter. The missiles have a range of some 400 kilometers, and can hit targets as high as 100,000 feet. The missile has a 320 pound warhead. The target acquisition radar has a range of 700 kilometers.
The S-400 has over five times the range of the U.S. Patriot, weighs twice as much and claims the ability to detect stealthy aircraft. The S-400 also has an anti-missile capability, which is limited to shorter range (3,500 kilometers) ballistic missiles. That would mean a warhead coming in at about 5,000 meters a second (the longer the range of a ballistic missile, the higher its re-entry speed.)
The S-400 system actually has two missiles, one of them being a smaller, shorter range (120 kilometers) one. The S-400 has no combat experience, but U.S. intelligence believes that the tests these systems have undergone indicate it is a capable air defense weapon. Just how capable won't be known until it actually gets used in combat.
Russia plans to buy up to 200 launchers (each with four missiles) by 2015, and phase out the older S-300 and S-200 systems. This would mean deploying at least 18 battalions in the next six years, and perhaps more than twenty. The S-400 is sometimes described as an improved version of the S-300. Basically, it is. This is how Russia prefers to develop weapons, making incremental improvements on a basic design, and doing so for decades if the system continues to be successful.
