The US is likely to announce this week the purchase of an advanced medium to long-range surface-to-air missile defence system for Ukraine, a source familiar with the matter has told Reuters.
Washington is also expected to announce other security assistance for Ukraine, including additional artillery ammunition and counter-battery radars to address needs expressed by the Ukrainian military, the source said on Sunday.
The weaponry is the latest assistance to be offered to Ukraine by the US since Russia invaded its eastern European neighbour in February.
This month, US President Joe Biden agreed to provide Ukraine with $US700 million ($A1 billion) in military aid, including advanced rocket systems that can strike with precision at long-range targets.
Ammunition, counter fire radars, a number of air surveillance radars, additional Javelin anti-tank missiles, as well as anti-armor weapons are also part of that package, officials said.
Another arrangement to sell four large, armable drones to Ukraine was paused earlier this month amid concerns their radar and surveillance equipment could create a security risk for the US if it fell into Russian hands.
