Russian long range ballistic missiles for S-400 Triumph surface-to-air missile systems will go into serial production in the autumn, a leading missile manufacturer said on Friday.

Earlier media reports said the S-400 missile system was incomplete as long range ballistic missiles, among others, had not been adopted for it.

"On December 26, 2009 the preliminary tests were finished and the missile was put forward for state tests," Kommersant daily quoted the general director of Almaz-Antei, Igor Ashurbeili, as saying.

"In the third quarter of 2010 we should finish them, along with combat duty launches, and then put it [the missile] into serial production in the fourth quarter," he added.

According to Ashurbeili, there were no technical failures or difficulties concerning the long range missile tests.

"The tests of S-400 missile lasted for about 3 years...We are bewildered by the bacchanalia of rumors and slander concerning the issue as an ordinary working process is going on," he continued.

Ashurbeili added that the situation regarding the production of missiles after 2012 is unclear as Almaz-Antei does not have "any signed contracts for 2012".

The S-400 Triumph boasts unique characteristics. It can destroy any air target, including aircraft, unmanned aerial vehicles, and cruise and ballistic missiles within a range of 400 kilometers and an altitude up to 30 kilometers. The system is almost three times more efficient than its Russian and foreign counterparts.

There are no plans so far to export the S-400. It will be produced only for the Russian Armed Forces. An additional two systems will be deployed by the end of 2010.
