It’s hoped the weapon will boost Ukraine’s lagging counteroffensive but the UN says they should never be used – and more than 100 countries have banned them.
President Biden has agreed to give Ukraine controversial cluster munitions to use against Russian troops.
The weapon detonates in the air and releases “bomblets” that scatter over a large area.
Opponents say they kill indiscriminately and that some of the smaller munitions can fail to detonate, posing a long-term risk to civilians.
US officials said the cluster bombs it will provide have a low “dud rate” of under 2.35% to minimise the risk.
President Biden called it a “difficult decision” but said he had to act as “the Ukrainians are running out of ammunition”.
He told CNN the cluster bombs were being sent as a “transition period” until it can supply more standard 155mm artillery.
Colin Kahl, under secretary of defense for policy, said “hundreds of thousands” were available but refused to state how many would initially be provided.
He said Russia had been using older cluster munitions with a dud rate of 30-40% since the start of the war.
Ukraine is said to have given written assurances not to use them in populated areas, to map where they are used, and committed to a post-war clean-up.
The US put off the decision “as long as we could” due to the risk to civilians, said Jake Sullivan, Mr Biden’s national security adviser.
But he said there was “a massive risk of civilian harm” if Russia takes more territory because Ukraine doesn’t have enough artillery.
Ukrainian presidential adviser Mykhailo Podolyak said cluster munitions could have an “extraordinary psycho-emotional impact” on demoralised Russian troops.
More than 100 countries are signed up to a convention against the use and manufacture of cluster bombs, but the US, Russia and Ukraine are not part of it.
“We’re not signatories to that agreement, but it took me a while to be convinced to do it,” President Biden told CNN.
He said he’d followed the recommendation of US defence officials.
NATO Secretary-General Jens Stoltenberg said the alliance had no position on the issue and that it was for “individual allies… to make those decisions”.
However, the United Nations has urged both sides not to use them.
UN human rights office spokesperson Marta Hurtado said “the use of such munitions should stop immediately and not be used in any place”.
The International Red Cross said cluster munitions “cause significant numbers of preventable civilian casualties”.
