Russian sub test-fires 4 intercontinental missiles in salvo

The Russian navy says one of its nuclear-powered submarines has successfully test-fired four intercontinental ballistic missiles in unison.

The navy said the submarine, named Yuri Dolgoruky after the medieval prince who founded Moscow, launched the Bulava missiles on Tuesday from a submerged position in the White Sea.

The navy said the mock warheads the missiles carried reached their targets on the opposite side of Russia— the Kura shooting range on the far eastern Kamchatka Peninsula.

The exercise marked the first simultaneous launch of four Bulava missiles, which can carry multiple nuclear warheads and has a range of up to 9,300 kilometers (about 5,770 miles.)

The Yuri Dolgoruky is the first in a series of new Borei-class submarines carrying the Bulava. Russia now has three and five more are under construction.
