The US says its latest aid package being sent to Ukraine will contain long-range missiles, capable of almost doubling their current attack range.
The ground-launched small-diameter bombs (GLSDB) are capable of hitting targets 150km away.
Up until now, Ukraine's longest-range weapon was the Himars rocket system, which can hit targets up to 80km away.
In a tweet Ukrainian President, Volodymyr Zelensky, thanked US President Joe Biden, saying:
"The more long-range our weapons are and the more mobile our troops are, the sooner Russia's brutal aggression will end".
Previously, Western nations have ruled out sending offensive weapons to Ukraine, which could be used to strike Russia.
It is reported that there has been speculation as to whether the weapons could be used to attack parts of annexed Crimea.
Pentagon spokesperson Brigadier General Pat Ryder told reporters "when it comes to Ukrainian plans on operations, clearly that is their decision,
"This gives them a longer-range capability, long-range fires capability, that will enable them, again, to conduct operations in defence of their country and take back their sovereign territory, Russian-occupied areas."

- Additional ammunition for High Mobility Artillery Rocket Systems (HIMARS)
