"Dad of all bombs."

Russia builds 'most powerful bomb'
Russia claims it has the world's most powerful non-nuclear air-delivered bomb
It is said to be more powerful than the U.S. "mother of all bombs"
Russia says it is similar to a nuclear bomb without harming the environment

MOSCOW, Russia (AP) -- Back in 2003, the U.S. proudly trotted out the so-called "mother of all bombs," a device described as the most powerful non-nuclear weapon in history.
Now, Russia claims it has built the "dad of all bombs."
Russian state television says the military has successfully tested what it describes as the world's most powerful non-nuclear air-delivered bomb.
The military claims the bomb is comparable to a nuclear weapon in efficiency and capability, but unlike a nuclear weapon, it doesn't hurt the environment.
The Channel One television report showed the bomb dropped by parachute from a bomber and exploding in a massive fireball. It featured the debris of apartment buildings and armored vehicles at a test range, as well as the scorched ground from a massive blast.
With extra oil revenues, the Kremlin has been taking steps to rebuild its global clout and its military.
