RIA Novosti: the main target of the S-550 will be the American space drones X-37 
The main target of the mobile missile defense system S-550 currently under development in Russia, will become the American space unmanned vehicles X-37, capable of carrying nuclear warheads. This was reported by RIA Novosti with reference to two sources in the military-industrial complex.
According to the interlocutor of the agency, the S-550 will specialize in the destruction of ballistic and orbital space objects, including nuclear warheads of intercontinental missiles. He stressed that among the typical targets of the Russian missile defense system can be called planning hypersonic units and drones, such as the X-37.
It is noted that in fact the new system will be a modification of the S-500 with specialization in intercepting ballistic and orbital targets .
Earlier, TASS military observer Dmitry Litovkin said that the Russian S-550 missile defense system is likely to work on the principle of kinetic interception of targets, which will eliminate the formation of “nuclear ash” over the heads of Russian residents when intercepting enemy missiles , for example the USA. The author notes that “in the case of the missile defense system in the USSR, the interception of nuclear warheads over the Central industrial region of the country was carried out by a counter nuclear explosion.” “Everything burned in the plasma cloud – decoy decoys and the warheads themselves. Thus, the “nuclear ash” still fell on the country. Logically speaking, the S-550 will work according to a different principle – kinetic interception, “the observer is sure.
