Russia has tested the world’s most powerful vacuum bomb, which unleashes a destructive shockwave with the power of a nuclear blast, the military said on Tuesday, dubbing it the “father of all bombs.” The bomb is the latest in a series of new Russian weapons and policy moves as President Vladimir Putin tries to reassert Moscow’s role on the international stage.

“Test results of the new airborne weapon have shown that its efficiency and power is commensurate with a nuclear weapon,” Alexander Rukshin, Russian deputy armed forces chief of staff, told Russia’s state ORT First Channel television. The same report was later shown on the state-sponsored Vesti channel. “You will now see it in action, the bomb which has no match in the world is being tested at a military site.”
