Putin claimed a new nuclear missile had unlimited range — but it flew only 22 miles in its most successful test yet

Russian President Vladimir Putin bragged earlier this year that his country had a new nuclear-powered missile with unlimited range — but it has yet to perform a successful test over multiple attempts, according to sources with direct knowledge of a U.S. intelligence report on the weapons program. The cruise missile was tested four times between November and February, each resulting in a crash, according to sources who spoke to CNBC on the condition of anonymity.
