These are top ten defense technologies of Russia for 2011, according to National Defense magazine.
The RS-24 Yars, a thermonuclear intercontinental ballistic missile, takes the lead of the list. It was first tested on May 29, 2007 to replace the older R-36 and UR-100N that have been already used almost for 50 years. The RS-24 is a missile that is heavier than the current Topol-M (which can carry up to 10 independently targetable warheads).
The second place goes to the Sukhoi PAK FA which is a twin-engine jet fighter being developed by Sukhoi OKB for the Russian Air Force. The Sukhoi T-50 is the prototype for PAK FA. A fifth generation jet fighter, the T-50 performed its first flight 29 January 2010. The PAK FA has a reported maximum weapons load of 7,500 kg. It has an apparent provision for a cannon. It could possibly carry as many as two 30 mm cannons. It has two internal bays estimated at 4.6-4.7 meters by 1-1.1 meters.
The S-500 is a new generation surface-to-air missile system, designed for intercepting intercontinental ballistic missiles and for defense against Airborne Early Warning and Control, Airborne Warning and Control System, and jamming aircraft. With a planned range of 600 km, the S-500 would be able to detect and simultaneously engage up to 10 ballistic supersonic targets flying at a speed of 7 km/s and will have a flight ceiling of 40 km.
The Yasen-class submarine, a new Russian nuclear multipurpose attack submarine class, takes the fourth place. The Yasen-class nuclear submarine is armed with cruise missiles, with several types suggested. It also has 8x650 mm and 2x533 mm tubes as well as mines and anti-ship missiles. This class is the first Russian submarine to be equipped with a spherical sonar, designated as Irytysh-Amfora. Yasen-class submarines will be the first Russian SSNs/SSGNs equipped with a fourth generation nuclear reactor.
