Russian strategic missile forces will put on service about 100 new Topol-M and Yars missiles by the end of this year, the Defense Ministry said Tuesday.

With the deployment, "the share of modern weapons in the strategic missile forces will approach 30 percent," ministry spokesman Vadim Koval told reporters.

According to the spokesman, the rearmament of Teikovo missile division has been completed. The division, deployed in Central Russia's Ivanovo region, has become the first in Russia which is fully armed with fifth-generation missiles.

Two regiments of Teikovo division have been armed with Topol-M, and two other regiments have received Yars missiles with multiple warheads, according to the ministry.

The Defense Ministry said it was also rearming the divisions stationed in Novosibirsk, Kaluga and Saratov regions with Yars missiles.

After the Saratov-deployed division receives Topol-M missiles by the end of 2012, "the program of re-equipment of the strategic forces with the Topol-M will be completed," Koval said.

Topol-M is a 47-ton solid-fuel missile capable of delivering 800 kiloton nuclear warhead at the range of 10,000 km. Yars is a 36-ton missile with the range of 11,000 km.

Moscow has announced plans to allocate 20 trillion rubles (over 600 billion U.S. dollars) for a massive upgrade of the armed forces until 2020.
