Turns out, Vladimir Putin’s unlimited range missiles do have limits.

The Russian president boasted in March about how Moscow developed a nuclear-powered missile with unlimited range, but four test firings between November and February show the rocket petered out in just minutes, according to a CNBC report.

Of the four launches, the longest flight lasted for a little more than two minutes, allowing the missile to travel about 22 miles before crashing, said CNBC, citing a US intelligence report on the weapons program.

The shortest test lasted four seconds and went five miles.

Asked about the duds on Tuesday, Kremlin spokesman Dmitry Peskov said Putin should be trusted over the US intelligence community.

“Listen to the president of Russia Vladimir Putin and believe him,” Peskov said, according to the TASS news service.

Putin, in his state-of-the-nation speech on March 1, warned the US about installing anti-missile systems in Romania and Poland and said his new hypersonic weapons would be able to defeat those defenses, calling them “invincible.”

“No one wanted to listen to us. Listen to us now,” Putin said.

The missiles, in development since the early 2000s, take off using a gasoline-powered engine but then switch to nuclear power for the flight, CNBC reported.

But during the tests, the nuclear-powered part of the missile failed to initiate and couldn’t reach the unlimited range Putin bragged about, the US intelligence report said.

It did not mention the environmental or health risks posed by the nuclear weapons damaged in the crashes.
