Russia began exercises with the Yars intercontinental ballistic missile system and several thousand troops, its defense ministry said on Wednesday, in what is likely to be seen as another attempt by Moscow to show off its nuclear strength.
President Vladimir Putin has aimed to make the Yars missile system, which replaced the Topol system, part of Russia's "invincible weapons" and the mainstay of the ground-based component of its nuclear arsenal.
"In total, more than 3,000 military personnel and about 300 pieces of equipment are involved in the exercises," the defense ministry said in a statement on the Telegram messaging service.
How are Russia's Yars missiles tested?
The drills involve the Strategic Missile Force's comprehensive control checking of the Omsk missile formation together with a command and staff exercise with the Novosibirsk missile formation equipped with the Yars systems.
During the exercises, the Yars mobile systems will conduct maneuvers in three Russian regions, the ministry said, without identifying the regions.
"Also, strategic missile men will carry out a set of measures to camouflage and counter modern aerial reconnaissance means in cooperation with formations and units of the Central Military District and the Aerospace Forces."
There are few confirmed tactical and technical characteristics of the Yars mobile intercontinental ballistic missile systems, which reportedly have an operational range of 12,000 km (7,500 miles).
According to military bloggers, the systems are able to carry multiple independently targetable nuclear warheads and can be mounted on a truck carrier or deployed in silos.
Since launching an invasion of Ukraine in February last year, Russia has conducted numerous military exercises on its own or with other countries, such as China or South Africa.
It has also increased military training with Belarus, which borders both Russia and Ukraine, conducting a series of comprehensive drills over the past year.
